The service life of refractory bricks is related to many factors. If it is used improperly, it may be damaged in one or two months. If used properly, its life may reach five years and ten years. So what do we need to pay attention to if we want a refractory brick to have a long life?
1. Adopt the correct construction plan to ensure the quality of masonry; the service life of refractory bricks has a great relationship with the quality of masonry bricks. From the production experience point of view, the masonry quality is good, the refractory brick can be as thin as 40mm without falling off. Although the temperature of the cylinder is high, it can still maintain production. It directly affects production and causes losses.
2. Strictly control the heating and cold kiln time; after new bricks are built, heating and drying bricks is very important, it directly determines the service life of refractory bricks. If the heating time is too fast, the refractory bricks will burst and peel, or even fall off, so each enterprise should formulate a suitable heating system according to its own characteristics.
3. Strengthen process management to ensure the correct use and maintenance in production; in normal production, whether it is improper operation or raw materials will cause different degrees of damage to the refractory bricks, so strengthening the maintenance in production has the protection of refractory bricks. Extremely important role.
4. Select the appropriate refractory bricks according to the conditions in the kiln; the main reasons for the damage of the refractory bricks in the kiln are as follows: First, thermal stress injury. When the kiln bricks are heated, due to the different temperatures inside and outside the The resulting expansion force causes cracking and damage of the refractory bricks, and the greater the temperature difference, the more severe the damage; the second is the flame erosion of the coal injection pipe, including the position, slope, axial and cyclone adjustment of the coal injection pipe, etc. Will have a huge impact on the service life of refractory bricks; Third, chemical erosion, such as clinker liquid phase erosion, harmful component erosion, etc., cause the refractory brick surface to peel;
This is the precautions for the use of refractory bricks, I hope that you all can have refractory bricks with long life.
