Product Description
Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips (green silicon carbide production need to add salt) such as raw material through high temperature electric resistance furnace smelting.There is also a rare mineral silicon carbide in nature, and the mo SangShi. Silicon carbide is also called the moissanite. In contemporary C, N, B the oxide refractory raw materials in the high technology, such as silicon carbide as the most widely used, one of the most economic, can be called corundum or refractory sand.At present China's industrial production of silicon carbide can be divided into two black silicon carbide and green silicon carbide.

- Q: Does anyone know the characteristics of refractory for glass kiln?
- Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
- Q: How can refractory materials be divided?
- Refractory materials in China can be roughly divided into refractory products and unshaped refractories.
- Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
- 3, the selection principle of antioxidant and its thermodynamic and kinetic mechanism31 selection principles of antioxidants:(1) according to the thermodynamic data and the conditions of use, the possible condensed phase and the vapor pressure of each gas phase are determined;(2) compare the size of each coacervation and oxygen affinity, and the possibility of reaction with CO.(3) the influence of various reactions on the microstructure of brick was analyzed.The thermodynamic and kinetic mechanism of 3.2 antioxidantsFrom a thermodynamic point of view, at the operating temperature, the additives or additives that react with carbon react with oxygen more closely than carbon and oxygen, giving priority to carbon oxidation, thus protecting carbon;From the analysis of dynamics point of view: the compound additive with oxygen and carbon monoxide reaction changed the microstructure of carbon composite refractory materials, such as increasing the density, blocked pores, hinder the diffusion of oxygen and reaction products.
- Q: Is fireclay poisonous?
- Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
- 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: How to prolong the furnace age of Induction furnace by using fireproof materials?
- magnesia solid materials have thermal endurance and erosion/ performance and its change of temperature is likely to cause cracks. properties of materials (aluminum) in such case have to be taken into consideration.
- Q: What kind of material is refractory bauxite?
- Bauxite in refractory industry usually refers to the calcined bauxite ore which contains Al2O3 no less than 48%, while the content of Fe2O3 is rather low. Clinker of bauxite with high alumina is calcined bauxite. Tghe clinker is grey, light yellow and dark gray.
- Q: The principle of choosing fire-resistant material in Thermal Energy and Power Engineering equipment.
- Different thermal technology equipment has different operation condition and select different refractory material. We should take economical and practical as principle.
- Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Hello there. Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.
