What are the requirements for temperature in the production of kiln bricks? Are we all ambiguous as in industrial kiln factories? In the production process of kiln bricks, the autoclaved aerated block control stage occupies a very important position. High temperature and high pressure steam curing can remove the free water in the kiln bricks, and the green particles are compressed and close to each other, which can reduce the thermal expansion damage caused by rapid evaporation of water. 1, heating stage in the premise of ensuring that the kiln brick is not affected by steam, the heating time should be as short as possible, as long as the continuous and uniform into the curing chamber steam 1.0~1.5 hours. 2, constant temperature stage constant temperature stage is blank

In the case of ensuring the drying effect of the drying kiln or at least ensuring that the drying kiln does not collapse, the heat extraction of the cooling zone of the baking kiln can be appropriately reduced. According to the heat balance calculation of the kiln manufacturer, the heat required for artificial drying accounts for about 30% of the total heat of the kiln. If measures can be taken to reduce this proportion to about 20%, a large amount of heat can be saved and the degree of under-fire of the finished brick can be reduced accordingly. The measures that can be taken are as follows: a. make full use of the storage line and let the well-coded brick blank be fully dehydrated by the ambient temperature on the storage line. For every 1% decrease in the moisture content of bricks entering the drying kiln, the heat consumption of the drying kiln can be reduced by 6% ~ 8%; B.
