Product Description

Mullite Four Hole Casting Steel Refractory Brick for Blast Furnace
The Description:

Flow steel brick, also known as pouring steel brick, is a hollow firebrick that connects the steel brick and the ingot mold in the groove of the ingot bottom plate, commonly known as Tang Dao brick. Flow steel bricks are generally rectangular hollow clay bricks with a variety of specifications. In order to reduce the resistance of the liquid steel flow process and prevent steel leakage, it is required that the inner hole of the flow steel brick is smooth, the shape is regular, the joint is tight, the resistance to acute cold and acute heat is good, and the correct size and regular shape should be used, because the flow steel brick is only used once, it is a kind of refractory material with large consumption in the pouring system. According to its use conditions, all sintered clay bricks are used, with good use and low cost. According to the production of steel grade, output, process requirements, the flow steel brick is divided into center brick, double hole, three hole, four hole steel brick, tail brick and so on.

Product features:
Al203 is required to be 36%-44%, refractoriness 1690-1710ºC, porosity in 17-25%, requiring good thermal shock resistance, so it is necessary to control the porosity between 1725%, low porosity thermal shock resistance is not good, high porosity is poor corrosion resistance.
Application:
The use of flowing steel bricks for the quality of molten steel lake:Flow steel bricks are usually used in the bottom casting method, the quality of flow steel bricks shadow the quality of ingot: when the molten steel flows from the steel tank to the ingot mold, through the flow steel bricks, due to the high temperature of molten steel, will have an impact on the convection steel bricks, thereby causing the local fall off of the flow steel brick structure, while the molten steel will interact with the flow steel bricks, chemical reaction products will be included in the molten steel, affecting the ingot The quality of...
