Refractory Runner Brick

【Product Introduction】

Refractory runner brick is a refractory component specially used in the flow channel system of high-temperature metallurgical furnaces. It is widely used in the tundish, distributor and flow channel structure of non-ferrous metal industries such as casting, steel, copper and aluminum.

【Product Features】

High Dimensional Accuracy
After CNC processing, the dimensional error of refractory runner brick is controlled within ±0.2mm. It is tightly installed and seamlessly connected to ensure smooth metal liquid and reduce heat loss.

Wear-resistant
Refractory runner brick is made of corundum, high aluminum or mullite, with a wear resistance of up to level 8, strong resistance to molten iron scouring, and a service life 1.5~2 times longer than ordinary runner bricks.

Applicable Equipment
It is widely used in thermal equipment such as molten steel tundish, aluminum alloy casting system, non-ferrous metal diverter, etc.

Applicable Medium
It can be used for a variety of metal liquid media such as molten iron, molten steel, molten aluminum, molten copper, etc.

【Frequently Asked Questions】

Q: What is the working principle of refractory runner brick?
A: Refractory runner bricks rely on their own high-temperature resistant materials to isolate heat transfer when high-temperature molten metal flows, maintain the stability of the runner shape, and ensure the smooth transportation of molten metal.

Q: In which industries are refractory runner bricks mainly used?
A: Refractory runner bricks are mainly used in the steel, casting, and non-ferrous metal smelting industries, and are used as diversion channels when pouring molten metal.

Q: What should be paid attention to when installing refractory runner bricks?
A: When installing refractory runner bricks, construction workers must ensure that the bricks are tightly spliced to avoid leakage from the gaps, and at the same time, they are firmly fixed to prevent displacement.

Q: How to clean the refractory runner bricks after use?
A: When cleaning refractory runner bricks, the operator must first remove the residual metal slag on the surface, and then use a high-pressure air gun to blow away the debris in the gaps.

Q: What are the requirements for the storage environment of refractory runner bricks?
A: Refractory runner bricks need to be stored in a dry and ventilated warehouse, away from water sources and humid areas to prevent the bricks from absorbing moisture and affecting their strength.
