This passage will tell the left effects of refratory bricks.
3.Changes in the original fuel
Only on the kiln with a stable operating conditions, can the tile lining adhere and maintain a solid kiln skin, and the life of the kiln lining can be guaranteed. The stability of the heat work system requires the stability The gray score changes between 32%and 45%. At first, in order to adapt to high gray coal, the raw material of the kiln was relatively saturated, but the coal ash was too frequent and there was no coal. It is difficult to correspond, which has a great impact on the condition in the kiln. After the maintenance, the firm kiln skin is about 20m, and the magnesium chromium brick is completely under the kiln skin. However, due to the fluctuations of coal, the kiln skin is frequent sticky and falling off, and the kiln skin that is aggressive with the brick platform to form a mechanical anchoring kiln skin is peeled together with the brick body layer to thin the brick body and shorten the kiln skin to shorten the kiln skin. At about 16m, some magnesium chromium bricks were protected by the kiln skin. At the end of the kiln skin, due to the sinking of coal ash, the kiln skin was thicker, and the raw material with less liquid phase was infiltrated here. Burning bands are directly combined with magnesium chromium bricks. It is mainly due to the direct combination of magnesium chromium bricks to resist high temperature and easy -to -hang kiln skin. Speed stones are mainly combined directly. In the existence of siliconate phase isolation, it is surrounded by magnesium and spinel crystal grains. The ability of anti -alkali erosion capacity and antioxidant and restore atmosphere is quite reduced. Especially on kiln that starts and stops more frequently, the life span is greatly shortened. There is no magnesium chromium brick without kiln skin as a barrier. The surface temperature changes with the kiln condition. Frequent fatigue, chemical erosion, and the infiltration of liquid -phase salt to worsen the structure of the brick, reduce the resistance of heat resistance, and keep the carcass temperature increased at this several rings of magnesium chromium bricks. Finally The water spray is forced to form a kiln skin on the fire brick, but the heating of the kiln disappears the stress compensation in the brick lining, which is not conducive to the life of the brick lining. In addition, the refractory brick body is too thin and cannot form a stable kiln skin. Only in the kiln digging, the thinnest part of the brick is only about 40cm. Magnesium chromium bricks at 2M at the kiln mouth also occurred. The kiln mouth is flat, and the kiln can not be sent to the kiln, which increases the temperature of the kiln mouth. Squeeze and make the alien bricks at 2M crushed, bricks, and red kilns.
4: Construction masonry process
The process of the fire -resistant tiles in the rotary kiln is rough, the ash joint control is not controlled, the latch steel plate is not firmly embedded, and the refractory brick has a crack section and other phenomena and is still used.
