What are steel shots used for, and what are the main uses of steel shots

In the use of steel shots, there will be many people in the question of what the specific use is, today to help you summarize the steel shot according to the different hardness classification and the use in the construction industry, a comprehensive understanding of the steel shot, so that it can be convenient to use a good steel shot in a reasonable place.

Steel shot is a very ideal abrasive product, in many castings in the sand cleaning treatment, the use of steel shot, good cleaning effect, steel shot is also widely used in the steel industry before the coating of the descaling and rust treatment. There are many classifications of steel shots, according to the different hardness of the steel shots manufactured, steel shots can be divided into cast steel shots, cast iron shots, glass shots, etc., and steel shots of different hardness have different uses.

The hardness of cast steel shot is generally HRC40-50, and the hardness can be increased to HRC57-62 by processing some harder metals. They have good toughness, several times the service life of cast iron pellets, and have a wide range of applications. The hardness of cast iron shot is HRC58-65, this kind of steel shot has high hardness, refrigeration is very brittle, very easy to break, short life, and not very widely used.

It is mainly used where high shot peening strength is required. The hardness of glass pellets is lower than the first two hardnesses and is mainly used in stainless steel, titanium, aluminum, magnesium and other situations where iron contamination is not allowed. It can also be used for the second treatment after steel shot peening to remove iron contamination and reduce the coarse friction of the surface of the part.

The use of cast steel shot in construction:

1. Transportation and navigation foundation engineering: high-strength concrete wear-resistant layers such as ports, docks, bridges, and airport runways.

2. Coal processing coal processing infrastructure projects in the coal industry: wear-resistant layers on the inner walls of loading coal bunkers, bottom coal bunkers, raw coal bunkers, buffer bunkers, lump coal bunkers, loading and unloading bunkers of container stations, leaky doors, chutes, etc.

3. Infrastructure construction project of cement plant in building materials industry.

4. Hydropower station infrastructure project: flood discharge tunnel, flood diversion tunnel, concrete wear-resistant layer on turbulent slope.

5. The wear-resistant layer of the inner wall of the clinker warehouse, the raw material warehouse, the homogenization warehouse and the wear-resistant layer of the ground of the gypsum board factory.

Shot blasting is to use a high-speed rotating impeller to throw the abrasive out and hit the workpiece at high speed to clean the surface;

Or it is a process that distorts and deforms the lattice on the surface of the workpiece through high-speed impact, increases the surface hardness, and strengthens the surface.

Before the shot blasting process, comprehensively check the overall status of the shot blasting machine, and select a reasonable current, projection angle, shot blasting speed, etc. according to the different models of the shot blasting machine.

The quality of the abrasive has a great impact on the quality of the surface treatment of the workpiece, such as the hardness, particle size and metallographic structure of the abrasive, which will affect the shot blasting effect.

Clean the molding sand and sticky sand on the surface of the casting; The surface obtains good cleanliness and the required roughness, which is conducive to processing and coating, etc.

1. Cleaning process: In this process, alloy steel shot can complete shot blasting cleaning, shot peening cleaning, die casting cleaning, casting shot blasting cleaning, forging shot blasting cleaning, forging shot peening cleaning, casting sand cleaning, steel plate cleaning, steel plate cleaning, steel plate cleaning, H-beam cleaning, steel structure cleaning and other work.

2. Derusting process: then relative to the first process above, the derusting process includes shot blasting and rust removal, shot peening derusting, casting derusting, forging derusting, steel plate derusting, forging descaling, steel derusting, H-beam derusting, steel structure derusting, etc.

3. Strengthening process: shot blasting strengthening, heat treatment parts and gear shot peening strengthening.

4. Shot blasting process: section steel shot blasting, section steel sand blasting, ship plate shot blasting, steel plate shot blasting, steel shot blasting.

5. Shot blasting process: steel plate shot blasting, steel shot blasting, section steel shot blasting.

6. Sanding process: sanding treatment.

7. Alloy steel shot pretreatment process: coating pretreatment, coating pretreatment, surface pretreatment, ship plate pretreatment, section steel pretreatment, steel pretreatment, steel plate pretreatment, steel structure pretreatment.

There are three main differences:

1. Appearance: The steel shot is round or a small amount of oval, and the steel grit is irregular and angular.

2. Shot blasting effect:

The surface of the workpiece treated by the steel shot is more delicate, and the surface of the workpiece thrown by the steel grit is slightly rough, according to the expected effect that the workpiece wants to achieve, it is decided whether to use the steel shot or steel grit, and the model is not static.

3. **: Steel grit is slightly more expensive than steel shot**.

Steel shot and steel grit are both used for shot blasting, rust removal, and surface strengthening treatment, and steel shot and steel grit have the following differences:

First of all, the appearance: the steel shot is round or a small amount of oval, the steel grit is irregular, the angular shot blasting effect says: the surface of the workpiece treated by the steel shot is more delicate, the surface of the workpiece thrown by the steel grit is slightly rough, according to the expected effect that the workpiece wants to achieve is to decide whether to use steel shot or steel grit, and the model is not static.

**Say: Steel grit is slightly more expensive than steel shot**.

Steel grit is the product of steel shot crushing.

Steel grit has the characteristics of being used repeatedly for several consecutive times, long life, strong adhesion, no breakage, and high brightness of the cleaning workpiece. As the name suggests, alloy steel shot is a pellet cut from steel wire, which is divided into stainless alloy steel shot and ordinary high-carbon alloy steel shot and low-carbon alloy steel shot according to the different steel wires. Below I will share with you the mixed use of steel grit and alloy steel shots:

According to the hardness of the steel pipe surface, the degree of original corrosion, the required surface roughness, the type of coating, etc., the abrasive is selected, and the mixed abrasive of steel grit and alloy steel shot is easier to achieve the ideal rust removal effect.

Steel shot strengthens the steel surface, while steel grit etchs the steel surface.

The mixed abrasive of steel grit and steel shot, usually the hardness of steel shot is 40 50hrc, and the hardness of steel grit is 50 60hrc, which can be used on various steel surfaces, even if it is used on the steel surface of grade C and D grade rust, the rust removal effect is also very good.

The surface treatment of steel pipes seriously affects the service life of pipelines, and it is also the simplest and most direct treatment method, so it is necessary to strictly follow the requirements of the anti-corrosion layer specification for the surface of steel pipes, and constantly explore, summarize and improve the surface treatment methods of steel pipes.

Regardless of the application field, the quality of alloy steel shot and steel grit is the key to effective operation, which determines whether it can effectively convert energy in the process of use, play a role in cleaning and strengthening, and also determine the level of your processing cost.

If you ask about the shape, the alloy steel shot is round, the shot is cylindrical, the steel shot is cast, so the particle size is uniform, and the shot is cut into sections, so it will have edges and corners; In terms of use, the steel shot is similar to hammering, like a lead ball smashed to the ground, forming a round pit, and the advantage of throwing is that the damage to the equipment is small, the throwing workpiece is beautiful, and the efficiency is low compared with the shot cutting; Cutting shot is similar to scraping, like a knife, the advantage is high efficiency, but there are scratches on the throwing workpiece, which is very damaging to the equipment, Lumbe Metal is happy to answer for you! Hope it helps!

It is said in the book that no matter how far a person has walked with you, he will still be separated from you in the end, after all, there are few people who were born at the same time, and people who grow old together not only have the parting in the relationship but also the parting of life and death, if you think so, even if you break up, you will not be so sad, but will wish each other happiness. If we meet one day when we are old, we will have a different taste in our hearts.

Many people in love will lose themselves and can't find themselves, and some people will cleverly hide themselves behind love, but they will reap the warmth and happiness of the heart. Some people are willing to give their lives for the sake of their lover, but they can do without it for her.

The main thing is to clean, strengthen, and remove rust, and remove the rust on the surface of the parts through the grinding of steel shots, or the oxide layer, so as to increase the strength, toughness and adhesion of the throwing parts. Steel shots.

The main purpose of steel shot is to clean and remove rust on the metal surface.

Steel grit is made from high-carbon cast steel shot by crushing into sand granules, and then tempered into three hardness (GH, GL, GP) to meet different needs, especially suitable for steel surface removal and scale pretreatment operations. GH steel grit is very hard and always has edges and corners during blasting operations, which is particularly effective for forming regular, hairy surfaces.

Steel shots are made from high-quality steel scraps, which are first melted and then formed into small balls with high-pressure water jets. The formed pellets are heated again to purify the homogenization and then quenched. The quenched pellets are dried in the furnace and reheated to achieve the proper hardness, and the tempered steel shots are sorted into 11 grades according to SAE standards through mechanical screens for use in blasting equipment.

Steel shot is a kind of spherical particles made of special materials by special heat treatment.
