- Q: What are the refractory stocks?
- The company produces energy saving, environmental protection type functional refractory materials and unshaped refractory materials. It is the main functional refractory material and unshaped refractory production enterprise in china. Company's products to new green high-quality refractory materials, energy saving and environmental protection as the leading iron and steel industry technological progress and improve the level of technology and equipment to adapt to meet the "development policy" refractories industry to develop industry, has a strong competitive advantage in the market. The main domestic refractory products company can only use part of the products of refractory materials production of iron and steel industry, iron and steel industry production and Pu resistant can be used in the vast majority of refractory products, iron and steel industry with the most complete refractory products. Therefore, the future development of the company is closely related to the prosperity of the iron and steel industry. More than more than 2000 enterprises in refractory industry, the company is the largest supplier of refractory materials in China, and the market share is less than 2%. Iron and steel group integration will inevitably lead to the overall contract cost control, supplier refractory decreases by seventy or eighty to two or three. The company's overall contract accounted for 37% (Montreal 68%), the overall contract increase will enhance the market share and profitability. China's urbanization, industrialization and investment in the 4 trillion infrastructure will stimulate sustained and rapid growth of China's steel demand. Therefore, in the long run, the prospects for the development of refractories for iron and steel are broad.
- 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: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: Manganese steel belongs to refractories
- Material wear and other harsh working conditions, extrusion, there will be work-hardening phenomenon rapidly on the surface. The most important feature of manganese steel is that it is not refractory under a strong impact, and under extrusion conditions, part of it will be fractured. The main form of damage is wear and consumption: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃, mainly used to endure impact. Manganese steel is a kind of high strength steel, which is free of deformation, so that it can remain austenite good toughness and ductility at heart while keeping good wear resistance at the same time on hardened layer. Refractories are
- Q: Can refractory be used as sealing element?

- Q: how to classify Insulating Refractory ?
- We are glad to answer your questions! This one is professional. My advice is to go through relevant webs for reference.
- Q: Can anyone tell me what is a high alumina refractory?
- Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
- Q: What's the fire resistance test method of doors and roller shutters?
- Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
