Electric furnace breathable brick

The ventilating brick of the electric furnace is a composite type of metal tube and magnesia carbon brick. The air vents are heat-resistant stainless steel pipes (φ3×1 or φ4×1), and the number of steel pipes is between 10 and 100 depending on the size of the brick. The matrix is made of high-quality magnesia carbon bricks, which is synchronized with the life of the furnace bottom. Due to the large number of steel pipes, it has a high blow-through rate and airflow stability rate under reasonable use, which can meet the requirements of electric furnace top and bottom blowing.
