What material is the surface layer of the breathable brick?

According to the assembly method, ladle breathable bricks can be divided into two types: internal integrated breathable bricks and external breathable bricks. Regarding the research of breathable bricks, people generally pay attention to the problems of resistance to melting damage of core bricks, resistance to penetration of molten steel and air blowing volume. , while the performance of the matching seat brick is relatively less considered.

The breathable brick is made of corundum, chrome corundum, corundum spinel, and is a supporting product for split and integral breathable bricks. It has high thermal strength, good thermal stability, good corrosion resistance and slag resistance , can effectively protect the breathable core brick. It is a key supporting product to ensure the smooth implementation of the bottom blowing argon function.

Blown vented bricks at the bottom of the converter are not cooled and quickly replaced by heat - challenge the whole life of the furnace and blow it again, take off the old ventilated bricks in one hour, and replace the new ventilated bricks in 2 hours!

The heat exchange technology provides a ventilated brick furnace bottom structure, which is characterized by a combined structure of a ventilated core block, a set of bricks, a seat block and a ventilated block fixing device, and a metal flange is connected and fixed to the converter shell.

1. General breathable brick: The surface material is a porous concrete material of general crushed stone.

2. Polymer fiber concrete breathable brick: the surface material is granite aggregate, high-strength cement and cement polymer reinforcement.

3. Colored stone composite concrete breathable brick: The surface material is natural colored granite, the marble is glued with modified epoxy resin, and then combined with the polymer fiber porous concrete at the bottom.

In addition, the breathable brick is a new century environmental protection building material that was born in order to cope with the hardening of the urban ground, create a high-quality natural living environment, and protect the urban ecological balance. Features.
