FUSED SILICA FOR REFRACTORY 1-3MM

Q:Who knows what material is in the center of fireproof rolling curtain?: In fact, in general, the middle of fire roller shutter is fire prevention materials, filled with asbestos fire protection materials in the fire shutter door of the two layer of iron sheet. I hope my answer can help you

Q:What refractories are accessible with ease in daily life?: Basically there have all materials. But it depends on your needs.

Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?: When casting ingot, after high temperature molten steel is poured into ingot mold, molten steel keeps shrinking during cooling, for example, killed steel is shrinking 3% --5%. because of fast heat dissipation of ingot head , some shrinkage holes appear at the head of ingot. Therefore, you should cut shrinkage holes which account for more than 15% of the ingot quality in the head while cutting steel ingot cogging. If effective measures were taken to insulate the head of ingot from heat, then the coagulation time of ingot head would lag behind in the body of the ingot solidification, which will greatly shrinkage holes, improve ingot yield so as to reduce energy consumption of steelmaking. Adiabatic plate can achieve this purpose. China Heng insulation board has the advantages of uplifting adiabaticity and small heat capacity, so that it greatly reduced heat loss of molten steel, And the tundish can be directly put into use without preheating, thereby saving a large amount of preheating fuel. So in the current process of continuous casting, the heat insulation board is the main material of tundish lining.

Q:What high-molecular polymers can be used as fire-resistant material binder?: Lignin is the least expensive.

Q:Does anyone know what is the use of waste refractory materials?: Waste refractory materials can be 1, Recycled to do the aggregate and powder of castable , or make bricks. 2, can be reused after smash.3, Metal silicon is an anti oxidant in refractory material, mainly functioning as he oxidation resistance, at the same time improve its toughness.

Q:what's the classification of fireproof materials?: Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.

Q:Do you know the refractories?: Definition of refractory: inorganic non-metallic material with fire resistance greater than 1580 degrees is refractory.Refractory material is a part of material industry. It is named refractory material for thermal kiln. Refractory materials are divided into conventional refractory materials and special refractory materials, and conventional refractory materials are used in metallurgical furnaces, cement kilns, glass kilns and other thermal furnace lining materials, mostly processed from natural raw materials. Special refractory materials are of high purity, mostly oxide synthetic materials, used in special smelting equipment, or special parts of kilns.

Q:Who knows what fire heat preservation material are there?: It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: Rock (ore) cotton, foam glass, inorganic thermal insulation mortar, etc.. 1 thermal insulation materials with class A combustion performance Phenol, powder polystyrene particles etc.. Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar. Hope my answer will help you.

Q:What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
