- Q: Which are fire proofing thermal insulation materials?
- aluminum silicate fiber, ceramic fiber, etc,
- 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: Does anyone know about the fire resistance period of thin fireproof coatings?
- The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.
- Q: Is aluminium oxide refractory material?
- Aluminium oxide with 2030?C melting?point is a kind of good refractory material. It can be used as analytical reagent, dehydration and adsorbing?material of organic solvent, catalyst of organic reaction, abraser,polishing agent, raw material of aluminum smelting technology and refractory material. Hope it is helpful to 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!
- What is said above ia wrong. Crusher choosed by general refractory material factory is roller type, for example: Roll crusher,teeth-roller?cracker. Choose different crushing equipment according to your requirements. You can go "Zhengzhou Keda Machinery Co., Ltd." to inspect! ! ---Hope it is helpful to you!
- Q: How to choose the material of refractory?
- Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
- Q: Could you tell me the fire-resisting time of class B fire proof door?
- The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
- Q: Introduction to refractory material
- Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
