- Q:How long is the fire-resistant time of fireproof wooden door?
- The fire-resistant time of fireproof wooden door is about 1 hour. Fireproof wooden door refers to the door whose door frames, skeleton of the door leaf, door panels are made of timber or timber work and fire endurance reaches the provisions of "GB50045-95 design of tall buildings for fire protection". Fireproof door is one of devices for fire?prevention and separation of the building, generally used on the firewall, entrance and exit between stairs pipe shaft opening, which plays an important role in the reduction of fire losses.
- Q:What are the materials used in refractory material processing?
- AZS special refractory brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so on. Unshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
- Q:What is the mechanism of the errosion of the iron to the refractories?
- For example, the effect of the iron oxide: Mo corundum given temperature Fe2O3 solid solubility limit of the solid solution formed of corundum stone high solubility than the solid solution Mo Mo corundum lattice shape so Fe2O3Al2O3-SiO2-based material starts melting temperature of the system or the content of Al2O3 and Al2O3 / SiO2 ratio off Al2O3 / SiO2 & lt; 2.55 starting melting temperature of 1380 ℃ when Al2O3 / SiO2 & gt; 2.55 start melting temperature is increased 1460 ℃ and with its Al2O3 content increased gradually to increase the original atmosphere Fe2O3 original FeO off the solvent into the glass phase and the system starts melting temperature drops do not fall to 1240 ℃ 1380 ℃. Lower the melting point, increase the erosion, and reduce the life span.
- Q:What kind of refractory material should be used for common boiler?
- Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red?brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
- Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.
- Q:Why the refractories should be waterproof and wetproof
- It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
- Q:What's the commonly used refractory material for ladle?
- Commonly used types of refractory material for ladle are as follows: high-alumina brick, clay brick, magnesia-carbon brick, aluminum carbon brick, magnesia chrome brick, spinel brick, corundum brick, high alumina castables, aluminum silicon carbide carbon castables, refractory castables for ladles, magnesium castables, magnesia chrome spray coating, dry vibration materials, etc. Hope it's helpful for you!
- Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- Now cone crusher is generally used.
- Q:Does anyone know what is a lightweight refractory material?
- The volume shrinkage is larger, and the corrosion resistance is higher at high temperature. A lightweight refractory material, used as thermal insulation material in industrial furnace and other thermal equipment, has poor wear resistance, weak mechanical strength and small volume density. Compared with ordinary refractory bricks, the lightweight refractory with low thermal conductivity has higher porosity.
- 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.
