Product description
The manufacturing process of fire brick sk34 includes the steps of raw material mixing, molding, drying and high temperature firing. Among them, the raw material mixing needs to be accurately proportioning, the molding process adopts pressing, extrusion, injection molding and other methods, and the drying methods include natural drying, air drying and hot air drying. High temperature firing requires control of parameters such as temperature, holding time and atmosphere to ensure that the physical and chemical properties of clay refractory bricks meet the requirements of the standard.
Advantages of fire brick sk34
The fire brick sk34 made by CH refractories with various size and free mold charge to meet different kiln applications. To be professional refractory blocks manufacturer since 1984, CH refractories also can design heat resistant bricks for sale, size according to your kiln drawing for free, and suggest you the most economical refractory bricks price for your kiln.
