Product introduction
Refractory bricks are called refractory bricks. Refractory fired from refractory clay or other refractory materials. Light yellow or brown. It is mainly used in building smelting furnace and can withstand high temperature of 1580 ℃ - 1770 ℃. Also called refractory brick. Refractory of certain shape and size. According to the preparation process, it can be divided into sintered brick, non sintered brick, fused cast brick (fused cast brick) and refractory and heat insulation brick; It can be divided into standard brick, ordinary brick, special-shaped brick, etc. according to shape and size. It can be used as the structural material of high-temperature building materials, building kilns and various thermal equipment. It can withstand various physical and chemical changes and mechanical effects at high temperature. Such as refractory clay brick, high alumina brick, silica brick, magnesia brick, etc.
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
Forsterite brick
It is a weakly alkaline refractory. Contains 35% ~ 55% magnesium oxide and a considerable amount of magnesium ferrite. MgO/SiO2 mole ratio is 0.94 ~ 1.33. The main crystalline phase is magnesium olivine 2MgO·SiO2 (abbreviated as M2Si). It has certain alkali slag resistance, high refractoriness and softening temperature under load, and strong iron oxide erosion resistance. Peridotite, serpentinite, pure peridotite and talc are used as raw materials and sintered magnesia is added in oxidizing atmosphere. The sintering temperature increases with the addition of magnesia. It can be used as the lining of non-ferrous metal melting furnace, steel making open hearth regenerator and cement rotary kiln.
