Silica brick high temperature resistance Refractory Materials Iron and steel smelting
Product introduction
Firebrick is called firebrick. Refractory material fired from refractory clay or other refractory materials. Light yellow or brown. Mainly used for building smelting furnace, can withstand 1,580 ℃ - 1,770 ℃ high temperature. Also called firebrick. Refractory material of definite shape and size. According to the preparation process, it can be divided into fired brick, non-fired brick, fused brick (fused cast brick), fire-resistant and heat-insulating brick; Can divide by shape and dimension standard brick, common brick, special unusual brick to wait. It can be used as high temperature building materials and structural materials for building kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical action at high temperature. Such as refractory clay brick, high alumina brick, silicon brick, magnesia brick and so on.
Its properties
1, chemical composition: the main composition determines the quality and characteristics of the refractory
2, volume density: unit volume weight, high density, indicating good density, strength may be high, but the thermal conductivity may be large.
3, apparent porosity: no specific requirements, but as a manufacturer must strictly control the apparent porosity.
4, load softening temperature: also known as high temperature load deformation temperature, this parameter is very important, marking the high temperature resistance of the material
5, thermal shock resistance: resistance to rapid temperature changes without being damaged
6, compressive strength: withstand (room temperature) the maximum pressure capacity
7, flexural strength: the ability to withstand shear pressure
Clay brick
Clay brick is mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and quartzite (up to 30%). Usually with hard clay as raw materials, calcined mature materials in advance, and then with soft clay, semi-dry or plastic molding method, temperature at 1300 ~ 1400 C fired clay brick products. You can also add a small amount of sodium silicate, cement and other bonding agents into non - burning products and amorphous materials. It is commonly used in blast furnace, hot blast furnace, heating furnace, power boiler, lime kiln, rotary kiln, ceramic and firebrick firing kiln.
