The Production Process of Refractory Brick
Date:2016-11-17 16:53 From:Zhengzhou Sunrise Refractory Author:admin
The variety quality of refractory materials has a big relationship with production process. The same raw material using different process, can produce need different varieties and
quality of products.
The production process of generally block burned into refractory brick:
1. Raw materials
Make different refractory products, need to adopt different chemical mineral composition of raw materials.
Refractory products demand for raw materials are: suitable chemical mineral composition and content of impurities in raw material: fewer and uniform distribution. Facilitate
mining processing and manufacturing, and lower cost.
2. The raw material processing
Raw material processing including mineral separation, drying, burning, crushing and screening.
3. Ingredients and mix practice (mixed)
Ingredients are the raw materials (large, medium and small three kinds of particles, raw material and clinker), additive (binder, mineralizer) and water to coordinate according to
certain proportion.
4. Molding and drying
The purpose of molding is to make the refractory products with specification density, appearance size and strength. Molding methods can be divided into new moon and semi-dry
forming. Metallurgical industry to use the most is the half dry molding in refractory products. The half dry molding can be divided into the machine and manual semidry molding
forming, the former is suitable for refractory brick with simple tile shape and big production, the latter is applied to small production, special shape brick is not easy to
mechanization operation.
