company news about Fired clay brick-Temperature should be controlled in the scope of what?

Clay brick is very popular in industry, use our customers know clay brick is very easy to use, clay brick but we will encounter can not be used, may be in the firing process because of too high temperature caused by clay brick is damaged, this requests us in when fired clay bricks must control the temperature, today let technical personnel gold tells you the temperature to control how much range when fired clay bricks?

When fired clay bricks are hierarchical, is generally divided into grade one and grade two, if at the time of firing temperature at about 1440 DEG C, and the temperature amplitude difference is within 50, then the holding time of it is in 40 hours. But if the clay brick level three words and the temperature at 1440 degrees, so the heat preservation time it than grade one and grade two to shorter. If the tunnel to the refractory brick of level one and level two use then in the temperature should be controlled in the range of 1500-1560 when firing. Also because of different firing of raw materials and product use different then in the firing when the heating speed is different, temperature rise to 600 degrees in the differentiation began, after according to the temperature rise of one point one points, has been the temperature reached 1200 degrees stopped.
