The firing process of refractory bricks includes the three processes of kiln loading, kiln firing and kiln discharge, which have a great impact on the quality of the finished product, so every step in the process must be treated strictly.
Loading kiln: The technical indicators of refractory brick loading kiln include kiln density (t/m3), effective cross-sectional area (%), effective heating area (m2/m2), etc. The heating rate of the product in the kiln is related to the effective cross-sectional area, the effective heating area, and the uniformity and uniformity of heating.
kiln: the kiln operation is carried out in accordance with the established firing system. For intermittent kilns, burning Chengdu requires three stages of heating, heat preservation and cooling, while continuous kilns only need to maintain the temperature of each part of the kiln and the cart system. In order to ensure the firing temperature system and firing atmosphere during the firing process, attention should also be paid to maintaining the pressure system in the kiln. In order to ensure the uniformity and stability of the product quality, the temperature difference in the kiln should be eliminated and reduced as much as possible.
Out of the kiln: The process of taking the burned products out of the kiln or unloading them from the kiln car is called out of the kiln. Care should be taken when leaving the kiln to avoid damage to the products during the kiln exit process. Products of different brick sizes and varieties should be strictly separated.
After the three steps of kiln installation, kiln firing, and kiln discharge, the refractory bricks are finished. However, its stacking problem must not be ignored. Different models and sizes must be stacked separately and arranged neatly to avoid damage caused by falling.
