Servel Kinds of Phosphate Bonded Refractory Castables
Phosphoric acid and acidic oxides hardly react and harden at room temperature. Therefore, it is not suitable as a binder for acidic refractory materials. Phosphoric acid reacts with amphoteric oxides (such as Al2O3) at room temperature to form a hard Read More …
Damage Mechanism and Cause Analysis of Refractory Castable for Water-cooled Beam
Because the working conditions of the refractory castable for water-cooled beams are very bad, the thickness is relatively thin, generally 50-60mm. It is only connected to the water-cooled beam by metal anchoring hooks. Under high-temperature conditions, it is affected by Read More …
High Temperature Refractory Castable for Heat Treatment Furnace
Many types of heat treatment furnaces are often used. The heat treatment furnace has low operating temperatures and good operating conditions. Generally use heat insulation refractory bricks or clay refractory bricks for the lining masonry. High alumina refractory bricks, cordierite Read More …
Refractory Materials for Grate Type Garbage Incinerators
There are many types of garbage incinerators. Refractories for garbage incinerators are mainly divided into refractory bricks and castables. Refractory bricks are mainly clay refractory bricks, high alumina bricks, and silicon carbide bricks. The refractory castables are mainly clay-based, high-alumina Read More …
Application Properties of High Alumina Cement in Unshaped Refractories
High alumina cement (formerly known as alumina cement). It is based on calcium aluminate and clinker with an alumina content of about 50% as raw material. A hydraulic cementitious material with aluminate as the main mineral component is prepared by Read More …
Several Kinds of Alkaline Refractory Bricks
Everyone knows that refractories are inorganic non-metallic materials with refractoriness not lower than 1580°C. Refractory materials must maintain stable chemical and physical properties at high temperatures to resist thermal shock or chemical attack. However, if you think that the chemical Read More …
5 Ways to Buy Refractory Bricks Cheaply
In many cases, customers do not know what kind of refractory bricks they need to buy for their factories. Only simply know that their factory needs refractory bricks. For example, a certain smelter is mainly engaged in the smelting and Read More …
Excellent High Temperature Performance of Silicon Carbide Refractory
Silicon Carbide Refractory is a high-quality refractory material that has long been known. It has high strength, high thermal conductivity, good shock resistance, oxidation resistance, wear-resistance and corrosion resistance. There are many uses in industrial sectors such as metallurgy, energy, Read More …
Clay Firebrick For Sale
Generally speaking, the fireproof degree of clay brick and silicon brick is equal, as high as 1690 ~ 1730℃, but the softening temperature of load is lower than silicon brick 200℃ above. This is because the clay brick contains nearly Read More …
