- Q: What is the importance of silicon powder in refractory processing?
- it can certainly improve the fire resistance
- 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: For refractory knowledge. What is the ratio of clay ramming?mass?
- Soil aggregates, dispersing agent, water reducing agent, plasticizer, binding agent and powder! ~ Bone meal feed approximately 6, OK
- Q: What's the maximum temperature that the refractory ceramic fiber cloth can endure?
- Ceramic fiber cloth is high temperature resistant and its continous use temperature can be up to 1000℃. It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; and it is easy to install.
- Q: What antioxidant will be used in refractories?
- Specifically speaking, it is an antioxidant used in carbon refractory products, which belongs to the fire resistant technology. A kind of refractory used antioxidants, formula proportion is as follows calculated by weight percentage: aluminium zinc alloy 1 ~ 100, conventional antioxidants in 0 ~ 100. Described in the aluminum zinc alloy element of aluminum content is 3% ~ 3%, the rest is zinc. Described aluminium zinc alloy is powder or fibrous long; The biggest size and long fiber powder makeup of maximum diameter is 0.2 mm. Preparation of the present invention contains aluminum zinc alloy antioxidants can prevent carbon oxidation temperature range is big, less side effects, and can adjust the thermal expansion of refractory. Hope I can help you.
- Q: What's the classification of refractory material?
- Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
- Q: What kind of refractory bricks material is best?
- Domestic experimental electric furnace body is made up of hearth, insulating layer and shell. Sic and high-alumina material are often used in traditional electric furnace under 1300℃ traditional furnace, while corundum material is used in 1600℃. Laboratory furnace of Occident usually uses ceramic fiber tank which is characterized by rapid temperature raising, good accuracy, light weight and small volume. In recent years, domestic Hangzhou blue sky Instrument and Shanghai laboratory equipment all have been produced by experimental furnace with ceramic fiber tank.
- Q: Does anyone knows which company produces the better refractory materials?
- 1, Xinjiang Seekon new material limited liability company: Xishan Street No. 382,Saybagh District 2, Refractory Material Co., Ltd. In Xuyan, Benxi: Near the Sihu Road, Benxi City 3,Benxi Beitai new refractory material factory sales office address: Benxi city Sihu District Liu Toro No. 16
- Q: Which basic refractory is better?
- Zhengzhou Xindeyuan Refractories Co., Ltd.and Zhengzhou Rongsheng Kiln Refractories cO.,Ltd. Their basic refractories mainly refer to refractories with magnesium oxide and calcium oxide as main components what can resist errosion of basic slag, including magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, dolomite?bricka and so on(magnesia bricks), among which magnesia bricks is the most common. Magnesia brick containing more than 80% to 85% magnesium oxide, has good resistance to basic slag and iron slag, and higher refractoriness than clay and silica brick. It is mainly used for open-hearth?furnace, oxygen-blown converter, electric furnace, ferrous metal smelting equipment and other high temperature equipments.
