Rongsheng Refractories Group
Sillimanitis is a natural high -grade refractory mineral, which has the characteristics of the low speed of thermal expansion, corrosion resistance to metallurgical slag and various glass liquids, as well as good wear resistance at high temperatures. The physical and chemical properties of syllimanite brick is better, than at High -grain brick, with a refractory of 1770-1830 ° C and the temperature of the start of loading loads 1500-1650 ° C.

The advantages of syllimanite brick
- Thermal expansion coefficient. Sillimanit – natural high -quality refractory mineral with an extremely low thermal expansion
- High softening point under load. The starting point of softening under the load is 1500 ° C-1650 ° C, With good heat resistance at high temperature
- High resistance to slag. Resistance to metallurgical sludge and various glass liquids
- Chemical corrosion resistance. Small contamination of glass fluid
What equipment is necessary for the production of syllimanite bricks？
Formation system., Computer Formation Management Program.
The system of ingredients. Automatic dosing on the radio and accurate weighing.
Mixing system. Use a mixer with an inclined angle for uniform mixing without dead ends.
Fighting system. Use a tunnel stove with a super -high temperature, which can reach 1800 ℃.
The use of syllimanite brick
It is mainly used to mold the holes for double -glazed windows, Fotter of blast furnaces, The neck of the furnace and ceramic furniture for industrial furnaces. Refractory materials, mainly consisting of natural sillimanitis, also have these advantages. Therefore, Sillimanite refractory is widely used in metallurgy, chemical industry and production of building materials.
Support individual Sillimanite refractory bricks
Fireproof brick made of sillimanite is an important refractory material for stoves for firing glass. Rongsheng can make refractory bricks of various forms for individual order. If you need fire -guidly bricks of a special shape, You need to send us the size and drawing of brick, And we will make them.
