What is a molten iron ladle used for? Can water in water work on iron?

The ladle is used for pouring operations in the foundry workshop, and after receiving the molten iron in front of the furnace, it is transported to the casting place by the crane for pouring.

Main technical parameters and dimensions.

1. Hanging bag form, two-way rotary type.

2. Reduction box form, double worm gear auxiliary drive.

3. Features. 1. The rotary center is reasonably selected, which is easy to operate, and can basically be reworked by itself after pouring.

2. Double worm gear pair drive is adopted. Although the manufacturing requirements are high, the transmission is flexible and free, and the two-way reversibility is good.

3. The boom is made of forgings, which is more reliable and safe than steel plate welding.

4. The steel plate of the package body is thick, and the bottom structure of the package adopts a triple insurance combining taper, bottom hoop and welding, which not only prolongs the service life but also ensures the safety of the operator.

5. The main body and the boom, the reduction box and the handwheel are all equipped with a chain card plate that can be locked at any time.

6. The two trunnions and the boom are equipped with spherical bearings, which are of good consistency.

Qingdao Shuangjie Machinery Factory is a member of the Ministry of Machinery Foundry Machinery Professional Production Factory, leading products: sand processing equipment. Clean up the device. There are more than 20 varieties of melting equipment in three series.

Structure and use.

R01 series hanging ladle can be divided into molten iron ladle according to its function. Ductile iron ladle. Teapot bag. Ladle. Among them, the molten steel contains a leakage bottom type, and the other ladles are pouring type.

The deceleration mechanism of the pouring ladle adopts the worm gear type and the package shaft connection type.

The worm gear is made of aluminum, iron bronze, and the worm is made of 45 high-quality carbon steel, which is made of quenched and tempered to make it durable, and the boom part is equipped with a safety fork device, which can ensure the safety and reliability of the molten iron lifting process.

The quality of the hot metal bag is good, and it is recommended that you go to their official website to understand.

<> dear, hello water-in-water can be on iron, imitation stone paint has fireproof, waterproof, acid and alkali resistance, and is resistant to positive branch pollution. Non-toxic, tasteless, strong adhesion, eternal and other characteristics, water-in-water coating construction, can effectively prevent the erosion of the building by the harsh environment of the outside Qingzai, prolong the life of the building, because the imitation stone paint has good adhesion and freeze-thaw resistance, so it is especially suitable for use in cold areas. Imitation stone paint has the advantages of simple construction, easy to dry and time-saving, and convenient construction.

The scientific name of water-in-water colorful tan dust smile paint is liquid stone. In general, the common name in the industry is called water-in-water colorful paint. Water-based multicolor paint is actually a dispersed aqueous phase of water-based latex coating, which is a multiphase suspension that protects the continuous phase composed of glue solution.

Water-based colorful coatings are mainly composed of continuous phase or dispersed phase, and the continuous phase has low concentration of continuous phase and low viscosity of continuous phase; The dispersed phase has high concentration, high viscosity, etc. Obviously, water-in-water can spray special paint for color steel.

I hope the above is helpful to you If you are satisfied with me, please give me a thumbs up

Ladle castable.

Magnesia is made of mid-grade magnesia and added in the form of fine powder. The purpose of adding an appropriate amount of magnesia to the substrate is to generate spinel with excellent slag resistance at 1200 1300 during use, and at the same time, it can also produce an appropriate amount of volume expansion, so that the whole ladle forms a whole. Its chemical composition is:

mgo≥95%；sio2≤；cao≤；Cauterization ; Bulk density. With the increase of magnesia, the swelling increased significantly, and the strength after firing decreased. The dosage should be about 7%.

As a ladle castable binder (additive) is more, such as: pure calcium aluminate cement, oxide ultrafine powder, silica sol, aluminum sol, phosphate, -Al2O3 or several kinds of combination, etc., at present, pure calcium aluminate cement, polyphosphate and oxide ultrafine powder are used more. The ratio of pure calcium aluminate cement combined with castable is the same as that of ordinary calcium aluminate water castable, but the calcium aluminate cement used has high purity, the chemical composition is mainly Al2O3 and CAO, and the impurity content is very small.

Pure calcium aluminate cement is synthesized by sintering method or electric melting method after mixing and grinding fine according to a certain proportion of industrial alumina and pure limestone or calcite, or industrial calcium phosphate. Its mineral composition is mainly calcium aluminate (and a small amount of calcium aluminate (. The coagulation rate is normal, the initial coagulation time is about 1h, and the final coagulation is 6 8h.

Sodium polyphosphate is a commonly used binding agent for alkaline refractories, which is characterized by very strong bonding, less wettability of the phosphate bond formed in contact with slag and molten metal, and good thermal shock stability.

The theoretical basis of the characteristics of oxide (silica fume, Al2O3) ultrafine powder is the surface phenomenon theory, and the fine powder has a dispersion and coagulation effect due to the existence of surface energy.

Here, according to the different effects of the binder, a composite binder such as pure calcium aluminate cement and sodium polyphosphate was selected.

Selection of additives. In order to make the castable have good dispersion, fluidity and low and medium temperature strength, silica fume is selected as an additive. When silica fume is added to calcium aluminate cement, Al2O3 powder, magnesia powder, etc., the original hydrate can be changed at low temperature and form a new hydrate with them, and these hydrates form a network chain, which can maintain its form to 1100 1200, so as to ensure that they have a fairly high cold state strength after medium temperature burning.

The results show that SiO2 powder has no other benefits in the castable except for increasing the strength at medium temperature, and brings a series of factors that damage the performance of high temperature. The amount of its addition should be in the range.

Foreign experts believe that after the silica fume is added, it reacts with calcium aluminate cement, not like the formation of cah10, c2ah8 and c3ah6 hydrates in simple calcium aluminate cement, but the formation of a similar zeolite type of calcium alumina silica hydrate, which is dehydrated after 300, and the time is short, and a large amount of steam is quickly released to cause bursting. For this purpose, an anti-explosion agent is added to the castable.

The quality of the castable depends on the quality of the aggregate and powder used, the particle size composition of the aggregate, and the amount of additives added.

At present, aluminum silicon carbide carbon bricks are used more, especially large iron ladles and torpedo tankers, and small ones use high aluminum. According to the composition of the molten iron and whether it is three off, the specific lining performance is determined.

Ladle bricks for cast iron can be used for a long time. View the original post
