- Q: What is the principal part of silicious refractory material
- blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon?dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica?brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
- Q: What is the difference between wear-resistant material and refractory material?
- Focus is different. Wear-resistant material may or may not be refractory. Such as, aluminum oxide ceramics is both refractory and wear-resistant, and many organic wear-resisting materials are wear-resistant but not fire-resistant. First, refractory material should be refractory. It should be wear-resistant in special cases. High-temperature fluidized bed, trough, etc. need refractory material with high strength and good wear resistance.
- Q: What are the requirements of refractory temperature of refractory brick?
- Oxygen fluctuation of load once happened during operation. Sometimes oxygen control valve will cause oxygen fluctuation of load, and sometimes large particles will block valve of high pressure coal slurry pump. The sudden drop in flow of coal slurry may cause relative excess of oxygen. Oxygen fluctuations directly cause fluctuations in furnace temperature. The range of oxygen fluctuations is 500m?-600m?. The maximum can reach about 1000m?. A sudden increase in oxygen causes a sudden increase in furnace temperature, which will suddenly burn out high-temperature thermocouple. The situation has a great influence on refractory brick and should be avoided. Furnace temperature is very inportant to life of lining of refractory bricks, so it should be strictly controlled not to overheat. There is a cinder layer on the surface of refractory bricks under the condition of normal production. In fact, cinder layer is dynamic. If the temperature is low, cinder layer is thick. If the temperature is high, cinder layer is thin. Appropriate cinder layer may slow the scour of high temperature gas and molten slag. The requirement of refractory brick is higher than that of stoves which use heavy oil as raw material. The main reason is permeability and corrosion of molten slag to refractory material. When replacing refractory bricks, it is found that penetration thickness is 10mm-20mm. After slag penetrates, strength decreases significantly. If temperature is high, erosion intensifies. According to the relevant information, when the operating temperature exceeds 1400 ℃, etching effect multiplies.
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- Refractory metal is used to lay and control cables, while trunking is used to lay wires and communication cables; refractory metal is bigger (200*100-600*200), while trunking is smaller; refractory metal has bigger turning radius, while trunking mostly turns a right angle; refractory metal has larger span, while trunking has smaller span; their fixation and installation ways are also different.
- Q: Is the linear change on reheating the same as heating permanent linear change of refractory material?
- “+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
- Q: What refractories can withstand high temperature above 2100 degrees?
- You can refer to advices from the first one coupled with the second one.
- Q: What is the fireproofing requirements of external wall thermal insulation materials?
- External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.
- Q: I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?
- Looking for refractory materials network, you can conduct online transactions, funds guaranteed
- Q: Which fireproofing materials factory is the best in Xiangyang?
- Xiangyang Shenglaide Door Technology Co., Ltd. Location: Taibai Road, Fancheng District, Xiangfan, Hubei Province Xiangyang Ai'ruite Door Technology Co., Ltd. Location: Scientific and Technical Pioneering Park, Xiangcheng District, Xiangfan, Hubei Province Xiangyang Innovation and Ideal Manufacturing Co., Ltd.

- 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.
