- Q: Procedures for producing common refractory materials?
- The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
- Q: What the fireproofing materialare of the refractory kettle and where they can be sold?
- Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
- Q: Urgently!! Refractory problems, online, etc.
- Uneven contraction. When the magnesia block wall is made, the steel wire mesh can be added to the magnesium block wall. That will solve the problem.
- Q: Which refractory material is better in China? Industrial furnace, mainly in non-ferrous industries, glass kiln, cement kiln business.
- Such solid nano microporous insulation material with nano inorganic refractory powder special, with a huge surface area, nano particles contact between the minimum point contact point contact thermal resistance is very large, the heat conduction effect of the material becomes very small, resulting in heat conduction coefficient of solid such nano porous insulation materials very small; nano pores formed of nanoparticles, the average size of 20 nm, and the average free path of molecular thermal motion at room temperature under static air is 60 nm, thus locking the air molecules in powder within nano pores, making the micro convection heat transfer effect between the stationary air molecules disappeared. The room temperature thermal conductivity of solid such nano microporous insulation material is lower than the static air; at high temperature, the main effect of heat transfer heat radiation, Good energy-saving insulation materials with nano microporous infrared additive special, stop at a high temperature and reflected infrared radiation, reduce the heat radiation effect to the lowest point, the radiation heat transfer coefficient of materials under high temperature is reduced to the lowest value.
- Q: Who knows about the differences between 3M fireproofing materials and ShiLiDe materials?
- ShiLiDe materials are rubbish which can not used in many industries now, because the main materials of which are mineral wool boards. These boards are harmful to human body, will lead to chronic poisoning, and the quality of which is bad! You must pay attention to it! They can not be used in chemical and pharmaceutical plants.
- Q: What is refractory aggregate?
- Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.
- Q: What do refractory materials include?
- What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded?magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- What thermal equipment? The most simple principle is durable, low cost and with no environmental pollution.
- Q: What are the characteristics of clay refractory materials?
- Refractory clay refers to the refractory clay and bauxite, whose refractoriness is over 1580℃, which can be used as refractory materials. Apart from high refractoriness, they can maintain stability of volume under high temperature conditions and has resistance to slag, the sudden cold and hot, and mechanical strength, so after calcination, it can be abnormal firm.
- Q: what needs to be noted when choosing and using blast furnace fireproof materials?
- Hello,: three parts of the blast furnace lining in general are easily corroded. The first one is furnace bosh,second is the middle part of the furnace, The third is lower part of the furnace stack. if These parts are damaged, then we need an overhaul. Bosh, because damage to the middle part of the furnace and the furnace bosh are generally due to alkali metal and fusant erosion. the main reason for the lower furnace part damage is molten iron, slag. In view of this situation, mullite bricks, corundum bricks, silicon carbide bricks are used for reparation. make repairments as soon as possible if any problems occur in case of incidents.
