FIRE CLAY BRICK SK-34 500*500*60 have been finished and passed inspection.
Clay refractory brick is a refractory material made of high-quality clay as the main raw material and fired at high temperature. It has good refractory properties, mechanical strength and chemical stability, and is widely used in various high-temperature industrial fields. The production process of refractory clay bricks mainly includes several links such as raw material preparation, molding, drying, firing and cooling.
1. Raw material preparation
2. Molding
Press molding: Put the mixed raw materials into a mold and press them into shape by pressure. This method is suitable for the production of small batches and high-strength refractory bricks.
3. Drying
4. Firing
The dried bricks need to be fired to enhance their strength and refractory properties. The firing process is carried out in a high-temperature kiln, and the temperature is generally between 1300 degree and 1500 degree . During the firing process, the chemical composition inside the bricks changes to form a dense structure.
The firing method is usually divided into continuous firing and intermittent firing. Continuous kilns are suitable for large-scale production and can improve production efficiency, while intermittent kilns are suitable for small-batch and special-specification production.
5. Cooling
6. Inspection and packaging
7. Storage and transportation
