The firing temperature of fired bricks is closely related to the firing temperature,so when producing this product,attention should be paid to observing its own temperature.If the temperature is too high or too low,it will affect the performance of normal operation.Next,let's take a look together:
1.If fired bricks are fired in tunnel kilns,such as first and second stage,the firing temperature is usually 1500~1560℃.
2.The heating rate varies depending on different raw materials and products.In the low temperature stage before 600℃,the temperature should slowly rise from:℃to 600-1200℃,and the heating rate can be slightly faster than:℃to 1200℃.The heating speed should be controlled at high temperature.
3.When firing fired bricks,such as first and second grade,the firing temperature is generally 1430-1450℃,and the insulation time is 40 hours.
4.When firing third grade bricks,the firing temperature is 1390-1400℃and the insulation time is 24-32h.
5.The cooling rate should also be controlled during the cooling phase.
The firing temperature of fired bricks of different grades varies and fluctuates,and controlling within this range will not affect the quality.The firing temperature of bricks should be adjusted at any time to meet the process requirements.
The above introduces the relevant content of fired bricks.The firing temperature of the brick is related to its production process,so attention should be paid to the operation mode of each link in the production of this product to ensure the stability of the brick in future use.Here,the editor suggests that everyone pay attention to the temperature and observe the surface treatment when using this product to ensure that the use effect of fired bricks is relatively stable.
