Several problems to be avoided in the construction of refractory bricks

Refractory bricks are mainly used to build smelting furnaces.1580℃—1,High temperature of 770°C.Refractory material with a certain shape and size.The correct and reasonable use of refractory bricks can give full play to the refractory properties of refractory bricks, provide the service life of refractory bricks, and extend the service life of refractory bricks. Let's take a look at the precautions for the use of refractory bricks.

1. When using refractory bricks, clean the dust and slag scraps on the inner wall of the kiln shell to avoid loosening.

2. The inside of the kiln shell should be flat without unevenness, let alone tilted.

3. The gap between refractory bricks is controlled within 1.5mm~2mm.

4. Use special cement for refractory bricks to bond refractory bricks.

5. Leave a little expansion joint between the refractory bricks.

6. The lining of important parts and parts with complex shapes should be pre-built; share refractory products from Yineng.

7. The lock seam should be firm.When processing bricks, use a brick cutter to finely process the bricks, and do not use hand-made bricks; the capping bricks in the rotary kiln and under the brick slabs should not be less than 70% of the original bricks; the joint bricks and curved bricks on the plane In, not less than 1/2 of the original brick.It must be locked with original bricks.The processing surface of the brick should not face the inner side of the furnace.

8. Refractory materials must be stored in a dry warehouse.
