Q: What requirements should refractory materials meet?: The operating temperature of forging furnace is above 1000, which can ensure the normal operation of the furnace, prolong the life of the furnace and save energy. General requirements for refractories are as follows. 1 They should deform at a sufficient temperature without melting. 2, They should have necessary structural strength without softening and deforming. The volume should be stable at high temperature without expansion, contraction or cracking. 4, They can resist erosion of molten metal, slag, gas and other chemicals.

Q: Refractory net: The development of the industry of refractory materials is very good, manufacturers are also more and more, especially in the Henan Xinmi side, next to the factory factory, we had visited gold refractory material factory, the scale is very large.

Q: How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?: Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.

Q: What is the function of refractory material?: Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.

Q: Why does refractory need to add coarse firstly and then add fine aggregate?: Binding agent can wrap particles and improve binding effect.

Q: what kind of fireproof materials is used for high rise buildings?: steel is recommended As a form of high-rise building structure, steel is widely used especially in the ultra-high-rise and long span construction showing strong vitality, for its high strength, light weight, and good extensibility, resistance to shock and short construction period. The mechanical strength of steel decreases with rising temperature at about 5000 ℃, decreasing about 40%-50%. the mechanical properties of steel, such as yield points, compressive strength, elastic modulus, and load capabilities have declined rapidly , quickly losing their ability to support, leading to building collapse. Therefore, it is imperative to protect steel structures. Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities.

Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: First of all, customer requirements, packaging according to customer requirements. According to the packaging packaging tray packaging is divided into 40 yuan / tons, carton 70 yuan / tons, 40 yuan / ton, straw packing bags of 30 yuan / ton.

Q: The development prospect of fire-resistant material: I also want to know, who can say, thanks all the way.

Q: Who knows about the fire endurance of grade C fire doors?: The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.

Q: What are the new refractories?: There are many of them. We can talk face to face. Sichuan Province Deyang City Xinxin Refractories Co. 0838-2228543
