Zircon brick heat insulation Refractory Materials Iron and steel smelting
Product introduction
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
Zircon brick
Zircon brick, in the process of steelmaking, the use of steel degassing method, and zircon stone refractory slag, molten steel corrosion resistance and thermal shock resistance is good, and suitable for working under pressure, it is widely used in the metallurgical industry for masonry degassing with sheng steel bucket lining, also used as stainless steel sheng steel bucket lining, Continuous casting steel barrel lining, casting mouth brick, plug brick, sleeve brick and high temperature induction furnace lining. Zirconia refractories are highly resistant to acid slag and glass, so they are also widely used in severely damaged parts of glass kilns for melting the most active glass. Zircon refractories are also impervious to aluminum, aluminum oxide and slag, so they have good effect on the bottom of aluminum smelting furnace.
