$Insulation Low Cement Refractory Castable For Rotary Kiln$

Q: what is best for making refractory insulation for Blast furnace, hot stove.: High dimensional insulating blanket.

Q: which kind of refractory is used in golden smelting furnace? How about his using temperature: generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q: Refractory materials are needed for casting metallurgy.: Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.

Q: What kind of refractory materials are used in metallurgy industry?: Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.

Q: What are the insulation fireproofing materials?: Asbestos is the most common. Asbestos containing zirconium and made of the mixture of zirconium aluminum and silicon through wire drawing is better. Of course, some are made directly from natural things which can withstand 1400 degrees for over 30 seconds while the internal temperature had no significant change, and withstand 1400 degrees for over five minutes while inside temperature increase does not exceed 5 degrees.

Q: What is special refractories?: Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use

Q: Does refractory belong to stone, building materials or other?: It belongs to building materials.

Q: Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?: Advertising materials can be divided into fireproofing and non-fireproofing ones which can not tell the differences with naked eyes. You can ask 3M to provide test reports or go to a the third party test organization SGS to do flame retardant test, maybe I can help you. Mineral wool board is harmful to human body, will lead to chronic poisoning, the quality of it is bad! You must pay attention to it! It can not be used in chemical and pharmaceutical plants.

Q: whether the aluminum silicate thermal insulation material is fireproof or not?: aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
