The impacting plate of tundish preform is made of magnesia, bauxite, white corundum, etc. as main raw materials, which are combined in the form of micro powder and ultra-micro powder, pre-molded with adding appropriate amount of coagulant and dispersant, and treated by baking at medium temperature. It has the characteristics of scour resistance, corrosion resistance and good thermal shock stability.

Silica stone and silica fume are mainly used as furnace burden for intermediate frequency furnace and tundish, and are also main raw materials for silica dry vibrating material for tundish. High-quality raw materials are the prerequisite for quality assurance.

This product is a quartz fireproofing material, which is a kind of acid dry ramming materials. It is made of high-purity quartz sand and quartz powder and particles, added with binder and anti-quick-cooling-and-heating stabilizer. It is widely used in the continuous and intermittent working environment of smelting nonferrous metals and ferrous metals in medium frequency electric furnace.

Dry vibrating material for tundish is refined from high-purity silica sand or fused magnesia as the main raw material, with special binders and sintering aid.

Silica ladle nozzle, also known as protective sleeve, is mainly used between steel ladle and tundish, and its function is to prevent the molten steel from being oxidized and splashed when entering tundish from steel ladle. Oxides formed when molten steel contacts air are the main sources of inclusions in finished products. And the air oxidation products are larger and more than deoxidation products in terms of the size and quantity of inclusions. The composition of inclusions is related to the chemical composition of molten steel, and its quantity and size are directly proportional to the time and area of molten steel exposed to air.

The slag retaining wall and current stabilizer of tundish preforms are made of magnesia, bauxite, white corundum, etc. as main raw materials, which are combined in the form of micro powder and ultra-micro powder, pre-molded with adding appropriate amount of coagulant and dispersant, and treated by baking at medium temperature. It has the characteristics of scour resistance, corrosion resistance and good thermal shock stability. Setting various forms of slag retaining walls in tundish can effectively make the inclusions in molten steel float up and separate to improve the cleanliness of molten steel. They can be built in the tundish with bricks or made into prefabricated blocks and then placed in tundish.

The in-use nozzle and the standby nozzle shall be placed in front and back of the same plane, supported by a high-temperature resistant spring, and the lower nozzle shall be replaced with hydraulic ejection method;

Castable, also known as refractory castable, is a kind of granular and powdery material made of refractory material added with a certain amount of binder, which has high fluidity and is an unshaped refractory formed by pouring.
