The advantages of silicon carbide refractory castable lie in its high heat conduction, low thermal expansion, and no reaction with slag. It has been used as slag reaction and high temperature peeling kiln site for a long time. The disadvantage of silicon carbide refractory is that the chemical properties are very unstable under certain atmosphere.In oxidation gases such as oxygen, water vapor, carbon monoxide, carbon dioxide) easy to corrode, iron oxide, etc, are easy to be in the hot metal and vacuum oxidation decomposition, the downside is that the refractory castable with carborundum dissolved water, in water system such as castable monolithic refractories, sometimes illiquid caused the density of silicon carbide refractory castable is bad, the third weakness is lack of sintering, hard to get high strength, but sometimes it is difficult to produce sintering and contraction, in monolithic refractories is a virtue.

This product is SiC castable developed by using high purity SiC raw material as the main material, pure calcium aluminate cement and micro powder as the binder, with high high temperature strength and wear resistance, and can be poured, sprayed and daubed.It can be used in waste incinerator, blast furnace body, cyclone furnace, effervescent furnace and boiler, etc.

Corundum ramming material is a clay billet or an amorphous mortar constructed by ramming, vibrating or pressing.Refractory aggregate, powder, binder, admixture or other liquid with certain grade.Press refractory orthopaedic material to be divided into: clayey qualitative, high aluminous qualitative, rigid jade qualitative, siliceous qualitative, magnesian qualitative, chromic qualitative, zirconia is qualitative and carborundum is qualitative refractory but plastic.According to the type of binder is divided into: sodium silicate, phosphate and binder refractory plastics, etc.According to the way of hardening, there are gas rigid or thermal rigid refractory plastic two. Corundum refractory plastic is made of wear-resisting raw material as aggregate, combined with powder or liquid binder and mixed with some additives.This product is suitable for circulating curing bed boiler cyclone tube, furnace wall lining and coal ash impact and serious parts.

Fused cast magmalox block, also named fused cast wear-resistance block, fused cast skid rail block, and fused cast zirconia mullite block. ZS Refractoriesâ?? fused cast magmalox block uses high quality bauxite, zircon sand and other raw materials, melting in an electric arc furnace at a high temperature ranging from 2000-2500�°C. The molten product then casted in molds, and kept to anneal for almost two weeks. It has advantages of compact structure, wear-resistance, impact resistance, strong thermal shock resistance, good corrosion resistance, slag resistance, and long service life. Being applicable in the areas of metallurgical pusher type reheating furnace, steel outlet tank, the lining of refuse incinerator, our fused cast magmalox block is also served as the key part of glass melting furnace.

Fused cast alumina block is also called fused cast block. As a kind of very important assisting refractories used in glass furnaces, it is composed of Alumina, Alumina and small amount of glass phase. It has superior corrosion resistance at the temperature up to 1350 C, zero bubble rate and pollution free to molten glass. It is also an ideal material for sidewall, paver of cooling zone/working end and the float canals of high quality glass furnaces. It is produced by melting and casting high purity alumina in electric furnace at 2000 corundum product is formed when alpha alumina and beta alumina inter-combine during their crystallization stage. In contact with molten glass, alpha beta alumina barely produces any blistering or stones. Therefore, alpha beta alumina blocks may be widely used in glass contact end zones of furnaces when glass quality is the priority. According to alumina content difference, fused cast alumina block can be categorized to fused cast (alpha) alumina block, fused cast (beta) alumina block, and fused cast block. We have casting method WS (VF) only.

Our fused cast AZS #41 block has the most corundum-baddeleyite eutectic crystals among the electro-fused Al2O3-ZrO2-SiO2 series products. Its corrosion resistance is the best and therefore its normally recommended to be used in quick wear positions to prolong the furnace life. It is the most widely used material both in glass contact and superstructure of glass melting furnaces. Mainly applicable for sidewalls, doghouses, throat, bottom budding, dam blocks, electric block corners, and also linings of furnace in industries. Our product has passed ISO international certification, it is made from high pure material, fired at high temperature by advanced technology, with the advantages of high strength, high compression resistance, good thermal shock resistance, good performance in high temperature, good thermal conductivity, good erosion resistance and so on. This product is available in a large size straight and special shapes which are available for special machining processes. We basically have three casting methods: PT, ZWS and WS, different required castings are manufactured accordingly.
