Features of coil grout

图片
Coil grout Coil grout works as refractory materials , it is mainly used between the working layer for sealing. Coil grout is characterized by high strength, high density and good insulation performance. Features of it are as following for your reference: 1.It has good insulation performance, which could prevent the coils from short circuiting or discharging. 2.It has excellent viscosity and easy to be constructed. It is applied to the coil to form the smooth surface, which could buffer the expansion and shrinkage of the working layer. 3.It could protect the furnace from the leakage of the metal liquid, stopping the coils from the metal liquids. 4.To support the coils, preventing the lining from deforming, especially the top of the furnace, it could prevents the coils from being scratched.

Converter Patching Material Furnace Patching Material, Converter Patching Material , Patching Material Application: Furnace patching material mainly applied for converter furnace hot patching, and suitable for periodic manufacturing. Property:   When converter furnace working, and the furnace patching material will flow to pit and fill broken departs. Thus to finish hot patching work. Ladle magnesia carbon brick Performance: 1. Patching material mainly made from high purity magnesia sand and synthetic dolomite sand, and mixed with wetting agent and agglutinant. 2. In high temperature ,which has performed flowability and can spread out automatically. Magnesia Carbon Brick for Converter 3. Scientific proportioning, low melting point, fast sintering speed,high adhesion, erosion resistance, long service life, environment friendly, suitable for patching broken departments 4. Saving time, energy conservation, improve furnace service life, does not pollute molten steel.

What is the role of silica in refractory materials

图片
refractory material The natural minerals of silica are called quartz. Refractory materials , clay and siliceous refractory material contain more silica. Silica is acidic at high temperatures, and siliceous refractories are resistant to acid residue corrosion. The main raw material for the production of clay refractory brick is natural refractory clay, the main mineral is kaolinite (molecular formula Al2O3 · 2SiO2 · 2H2O), clay brick containing SiO2 between 45% and 65%, are weak acid refractory, Have a certain resistance, but easy to be alkaline slag erosion. Low alumina clay refractory suppliers refers to the alumina content of 10% to 30%, SiO2 content of less than 85%, semi-silica refractory brick ≥ 65% SiO2 content of not less than 93%, natural quartzite as the main raw material of refractories known as silica, mainly silicon bricks, special silica bricks, quartz glass and its products. China's literature generally referred to these products as "silicon refra
