What is the continuous casting process and what is the continuous casting billet

The ladle containing the refined molten steel is transported to the rotary table, and after the rotary table is rotated to the pouring position, the molten steel is injected into the tundish, and the tundish distributes the molten steel to each mold by the nozzle. The mold is one of the core equipment of the continuous caster, which makes the casting form and quickly solidify and crystallize. The tension leveler and the crystallization vibration device work together to pull out the casting in the crystallizer, and after cooling and electromagnetic stirring, it is cut into a slab of a certain length.

The automatic control of continuous casting mainly includes the speed control of the blank roller of the continuous caster and the vibration of the mold.

Control technology such as dynamic frequency control, fixed-length cutting control, etc.

It is the production process of continuous casting billet, from the production operation process of the big bag on the stage to the production operation of the blank off the line, and the continuous casting workshop is divided into two groups of people (posts) and maintenance.

Continuous casting is the abbreviation of continuous steel casting, which is a process of solidifying molten steel into a billet after steelmaking. Continuous casting billet is a product obtained by casting molten steel made from a steelmaking furnace through a continuous casting machine. There are two main types in terms of appearance:

Slab: The ratio of cross-section width and height is large, and it is mainly used to roll plates. Billet: the cross-sectional width and height are equal, or the difference is not large, mainly used for rolling section steel and wire rod.

Related Notes:

Cast steel refers to steel that is used exclusively for the manufacture of steel castings. When the strength requirements of the casting are high and the cast iron cannot meet the requirements, cast steel should be used. However, the fluidity of molten steel in cast steel is not as good as that of cast iron, so the thickness of the cast structure should not be too small, and the shape should not be too complex.

Controlling the silicon content at the upper limit improves the fluidity of the molten steel. According to the variety and use, cast steel can be divided into cast steel for general engineering, cast steel for welded structure, stainless steel cast steel, and heat-resistant steel cast.

Cast steel can be divided into cast alloy steel and cast carbon steel according to its chemical composition, and can also be divided into cast tool steel, cast special steel, cast and cast alloy steel for engineering and structure according to its use characteristics.

The billet produced by the continuous casting machine is called continuous casting billet.

Continuous casting billet is a continuous casting profile, and continuous casting is divided into copper, iron and steel continuous casting.

Continuous casting is the abbreviation of continuous steel casting. There are two methods of solidification and forming of molten steel in the production of various types of steel products in steel mills: traditional die casting and continuous casting.

In the fifties of the twentieth century, the continuous casting technology that appeared in Europe and the United States is an advanced technology that directly pours molten steel into shape. Compared with traditional methods, continuous casting technology has significant advantages such as greatly improving metal yield, casting billet quality, and saving energy.

History

Since the fifties of the twentieth century, the production process of continuous casting began in the steel mills of European and American countries, and the process of directly casting liquid steel into formed steel products through the continuous casting machine has greatly shortened the production time and improved the work efficiency compared with the traditional casting and then rolling process.

In the eighties, the continuous casting technology as the leading technology gradually improved, and in the world's major steel-producing countries have been greatly applied, to the early nineties, the world's major steel-producing countries have achieved more than 90% of the continuous casting ratio. After the reform and opening up, China really began to digest and transplant foreign continuous casting technology; By the early nineties, China's continuous casting ratio was only 30%.

What process can replace continuous casting.

Dear, I'm honored to have your question The information that the teacher found for you here is: what process can replace continuous casting: the process that can replace continuous casting is Tangyanzhou mold casting, "The entire continuous casting pouring process is realized by 3 to 4 robots, which completely replaces the manual operation of the continuous casting pouring link."

Xiao Xiaowen introduced that this kind of "one-click" pouring Xiangzhou not only reduces labor costs, but also ensures the stability of the continuous casting ring.

First, the reference is different.

1. Die casting: It is a forging method for mass production of forgings.

2. Continuous casting: that is, the forging method of continuous casting steel.

Second, the process is different.

1. Die casting: Under the action of forging machinery, the blank is forced to form plastically in the forging die chamber, so as to obtain the required shape, size and certain mechanical properties of the die forging.

2. Continuous casting: the initial rolling and billet opening process can be omitted, which not only saves the energy consumption of soaking furnace heating, but also shortens the cycle time from molten steel to billet. One of the main developments in continuous casting in recent years has been the trend of casting billets close to the cross-sectional size of the finished product, which will simplify the rolling process.

Third, the application is different.

1. Die casting: The production is mainly for automobiles, agricultural machinery, rolling stock, engineering and power machinery, machine tools, aerospace and military industry to provide key parts blanks or finished parts, such as crankshafts, connecting rods, front beam buried cavities, half shafts, universal joint forks, sliding forks, cross shafts, constant velocity universal housings, gears, synchronizer gear rings, blades, worm wheel disks, nozzles, valve bodies, pipe joints, etc.

2. Casting of bent shirts: widely used in the manufacture of hydraulic valve bodies, high-pressure parts, gears, shafts, plungers, printing machine rollers and textile machine parts. In automotive, internal combustion engine, hydraulics, machine tools, textile, printing, refrigeration and other industries.

The three major process systems of continuous casting are ().

a.Temperature system, speed system, cooling system (correct answer) bCooling system, furnace matching pants system, temperature system.

c.Pulling speed system, middle package replacement system, cooling system.

1. Ordinary casting, which is often called sand mold with collapse casting.

2. Special casting, including gravity casting, low-pressure casting, high-pressure casting, investment casting, centrifugal casting, vacuum suction casting, negative pressure casting, squeeze casting, forging, liquid die forging, etc.

Lost foam casting (also known as solid casting) is a new casting method in which paraffin or foam models similar to the size and shape of castings are bonded into model clusters, brushed with refractory paint and dried, buried in dry quartz sand and vibrated for molding, poured under negative pressure, so that the model is vaporized, liquid metal occupies the position of the model, and the casting is formed after solidification and cooling.

Precision casting, also known as lost wax casting, its products are precise, complex, close to the final shape of the part, and can be used directly without processing or very little processing, so investment casting is an advanced process that is close to net forming.

Sand casting first makes wood mold - modeling - melting - pouring - sand removal - riser removal - inspection and storage.

This is just the casting process in the foundry, and the product performance of each process is different. If you want to find a suitable foundry for a demolition of acres, you must be clear about the process you need, the transportation distance, the delivery date, etc. Hefan for these aspects of Hefei Quansheng Machinery is very good, is Hefei large-scale cast steel and cast iron manufacturers, the production of castings, never slack off, welcome to view cooperation.

First of all, what is a casting billet? Liquid molten steel needs to be cooled to convert into a solid state, and we generally turn the molten steel into a more regular solid, and then carry out subsequent processing, and finally transform it into a finished product. Before the invention of continuous casting technology, it was generally necessary to pour liquid molten steel into a mold of a certain shape, then cool it, and then demold it after it was completely solidified, which was called a steel ingot.

After the invention of continuous casting technology, there is a continuous casting billet, and the continuous casting equipment includes from top to bottom, ladle - tundish - mold and its vibrating device - sector section and its cooling device - cutting device and so on. Because continuous casting has greatly improved the productivity of casting billets, so that the world's steel production and quality have developed rapidly, except for special products, the current continuous casting technology has basically replaced die casting.
