Q: What is the heat preservation material used in a laboratory furnace?: Thermal insulation cotton is a high-purity clay clinker, alumina powder, silica powder, chromium sand and other raw materials in the industrial furnace melting at high temperature, forming fluid. Then, compressed air is used to blow or use the wire throwing machine to turn the yarn into a fiber shape. After the cotton collector is collected, the cotton is formed into a heat preservation cotton.The high alumina brick is usually made of high alumina clinker with small amount of clay. After grinding, the high alumina brick is poured and shaped in the form of slurry by the way of gas generation or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.

Q: What are the main components of high alumina bricks?: High alumina brick materials according to the main mineral phase can be divided into: aluminum silicate minerals, such as sillimanite, kyanite, andalusite, and synthetic mullite.

Q: Introduction of high alumina brick: Three alumina silicate refractory product with a content of two Al2O3 (48%).

Q: What's the difference between high alumina refractory bricks and high alumina refractory bricks?: High alumina refractory brick in all thermal shock properties except performance are better than clay refractory brick, masonry in furnace and thermal equipment, such as clay bricks can be competent the work environment is not high aluminum brick masonry.

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: RT3 series trolley type resistance furnace is a national standard energy-saving cycle type operation furnace. It has super energy-saving structure, adopts fiber structure and saves electricity 30%. Exclusive production of composite high aluminum nails group, car anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, without the basic installation, placed on the ground floor can be used. Mainly used for high chromium, high manganese steel castings, ductile iron, roller, steel ball, 45 steel, stainless steel quenching, annealing, aging, and various mechanical parts heat treatment. Features: 1, no noise, no environmental pollution. 2, small heat storage, less heat loss. 3, high temperature control accuracy, furnace temperature uniformity. 4, a high degree of automation, simple. 5, PID programming can be used to set, fully automatic operation. 6, good sealing, long life, safe and reliable. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electricity, ships, paper, mining, medicine, central heating and other industrial sectors. With the development of social productive forces, its application in various industries is more and more widespread. Two, pitannealingfurnace (for example: flange heat treatment furnace) use: the furnace for metal parts, such as ring of equipment heat treatment at rated temperature: the furnace is composed of furnace body and a movable furnace cover and control system.

Q: What are the common thermal insulation materials for thermal conductivity?: The vacuum heat insulation plate is a kind of high efficiency thermal insulation board made of inorganic fiber core material and high resistance gas composite film. It is made of vacuum encapsulation technology and covered with special interface mortar.

Q: What are the alloy wear resistance materials?: KNMn19Cr2 (patent) high manganese alloy (ZGMn13Cr2MoRe), super high manganese alloy (ZGMn18Cr2MoRe); two: anti-wear chromium cast iron series: such as high, medium and low chromium alloy cast iron (Cr15MOZCu); three: wear resistant alloy steel series: such as, low and high carbon multi metal combined steel (such as ZG40SiMnCrMO and ZG35Cr2MoNiRe); four: ADI (ADI) series; five: all kinds of composite or gradient material and hard alloy materials, nano KN alloy (patent product): such as chromium carbide composite (Cr2C3+Q235), high-energy ion osmosized tungsten carbide materials (WCSP), high toughness of cemented carbide (YK25.6), KN999 nano alloy (Beijing Naimo patent) etc.;

Q: Which is better, the soft core or the hard core?: When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.

Q: What are ordinary bricks, refractory bricks, hollow bricks?: Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..

Q: What does refractory consist of?: Refractory materials can be divided into main raw materials and auxiliary raw materials according to their function in the production process of refractory materials.The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.
