Rotary Kiln Lining Choose Castable or Refractory Brick

Rotary kiln is an important production equipment, mainly used in cement, steel, chemical, and other industries. For the selection of rotary kiln lining materials, both castables and refractory bricks can be used. Here is a comparison of the two materials:

Casting Material
Casting material refers to the material that is poured into the lining mold after mixing the materials. Its advantages include that it can meet the needs of various shapes, can reduce brick joints, has wear resistance and impact resistance, and is easy to use. However, the production of castables requires a high level of technology, and the consistency of material properties is difficult to ensure, so the production process needs to be carefully controlled to ensure the stability of material quality. In addition, castables have a relatively short service life and need to be replaced frequently.

Refractory Brick
Refractory brick is a material made of bricks fired at high temperatures. Its advantages include good high-temperature stability, high mechanical strength, strong corrosion resistance, etc., and can be used for a long time. However, the production and installation of refractory bricks require certain skills and experience, and the shape and size of the bricks are fixed, so correct measurement and installation are required to ensure the quality and stability of the lining. In addition, refractory bricks are prone to cracks and breaks during use and require regular inspection and replacement.

Therefore, the selection of the material for the lining of the rotary kiln should take into account the specific production needs and cost considerations. When selecting materials, it is necessary to comprehensively consider factors such as service life, stability, and cost to achieve an ideal choice.
