- Q: What is the difference between wear-resistant material and refractory material?
- Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
- Q: Who knows the model of fireproofing materials?
- Inorganic binder: it mainly includes sodium silicate, gypsum, phosphate, cement,etc; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch,etc; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin,etc. Nonflammable fireproof addictive: it mainly includes phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, TBP ( tributyl phosphate ), decabromodiphenyl ether), and borate series (boric acid, zinc borate, aluminium borate), antimony series, aluminium series, zirconium series and other inorganic compounds.

- 1 hour. It is in line with the fireproof test standards of national building materials . CaSo4.2H2O is molecular structural formula of gypsum which contains 20% water, crystal water and free water. When 10% water slowly evaporates on the flame surface, there is still 10% crystal water. Itself is grade A fire retardant material. It can reach up to four hours at most.
- Q: What a blast furnace refractories generally?
- refractories for blast furnace include carbon brick and silicon-aluminum refractory. BF carbon brick inlcudes half-carbon charcoal bricks, microporous charcoal brick, ultra porous charcoal bricks, graphitic brick and mould pressing charcoal brick. tiles and molded graphite small charcoal bricks. I hope my answers above are helpful to you and your ideal anwers.
- Q: What refractory material does cupola lining use?
- In order to improve the service life of the lower wall and the bottom leather, dense and high alumina brick can be used for masonry. The front furnace is composed of the bottom, the wall and the top. The top of the furnace is vaulted or hanging flat roof. The front furnace body is usually made of clay brick and high alumina brick, and the bottom work floor is rammed with ramming material. The material is the same as that of cupola furnace. The bridge and the front guard taphole, slag hole and other parts due to erosion by high temperature molten iron and slag erosion, lower service life, frequent repairs. Large blast furnace adopts hot blast or oxygen enriched blast, which has higher temperature and higher production capacity... The damage is faster, and it is hard to maintain production by using clay brick or high alumina brick. Should be used aluminum, carbon or corundum refractory silicon carbide castables pouring or tamping, so that the integrity of good, high strength, corrosion resistance, and therefore significantly improved service life, generally up to one year or so. Refractory materials, including chimneys and spark traps, are used in other parts of the cupola. The chimney and the cupola shaft directly connected with the shell made of steel plate, lined with ordinary clay brick, can also be used ordinary refractory castable pouring. The chimney is provided with a furnace heat exchanger, which can preheat the air to 300~500 DEG C, and the spark collector is used for catching the hot coke and dust particles brought out in the flue gas. The chimney at the top of the reflector (cover) by plate welding, can also be used to cast iron, its lining refractory coating or spraying paint.
- Q: What are the main components of refractory cement?
- SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
- Q: Who know about the knowledge of acid refractory material? Please explain in detail.
- Abrasion resistance of fire resistance material depends on the material group and structural material. The abrasion resistance of dense single crystal materials depends on the hardness of mineral crystal. The higher the hardness, the more resistance the material is to abrasion. non mineral crystals with fine grain material has a high wear resistance. The abrasion resistance of materials is related to bulk density or porosity. Aluminium refractory material can resist a temperature as high as 700~900 degree within the elastic range. The higher the temperature, the lower the resistance. Abrasion resistance will be increased with elastic modulus as temperature increase. In many cases, refractory material will often cause a lot of harm due to mechanical abrasion.
