1.Structure of Calcined Bauxite Description
Bauxite (aluminous soil; Bauxite) is also called the alumina or bauxite, main ingredients are alumina, hydrated alumina containing impurities, is an earthy mineral. White or gray, brown and yellow or light red by iron. From 4 to 3.9 g/cm3 density, hardness, 1 ~ 3 is not transparent, very brittle. Very difficult to melt. Insoluble in water, soluble in sulfuric acid, sodium hydroxide solution. Mainly used for aluminium, refractory material.

- Q: who knows the fire resistant levels of fireproofing glass?
- According to the fire resistance levels, it can be divided into three categories: Class A: a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B: Marine fireproofing glass, including porthole fireproofing glass and rectangular window fireproofing glass, surface glass pane is tempered safety glass, the inner surface glass pane material can be arbitrary selection. Class C: it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements.
- Q: Can quantitative feeder be used in refractory plant? Thank you
- Feeder experts, justice and analysis, quantitative feeder, of course, can be used in refractory plants
- Q: What kinds of refractory will be used in kiln of sintering ceramics?
- If it is ordinary ceramic, you can use ordinary clay bricks and high alumina brick, adding calcium silicate board, the insulating brick and cotton fiber.
- Q: What type of firebrick does TZ-3 represent?
- Z represents a straight brick, T stands for common brick, common straight standard brick, -3 represents the length, and the specification is 230 * 114 * 65 (mm).
- Q: who knows the requirements of refractory for forge furnace?
- Forging heating furnace working temperatures above 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. refractory is generally required to have the following properities: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
- Q: what is the common materials for home fireproofing material?
- 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion
- Q: How long is the fire endurance of the rock wool board?
- Some time ago we did an experiment, the result is no change in the burning 30 minutes. The following is the picture of rock wool after the test .
- Q: Which brand of refractory fiber hard thermal insulation board is better?
- Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.
- Q: what should be paid sttention when buying the refractory?
- First, look at the appearance of the product, it will be better if the surface of product is smooth, if there are the injuries and damages which may influence the use, do not use it. Second, the main characteristics of insulation material is flame resistance, reduce the loss of fire occurred at the time of purchase combustion performance testing products, non-combustible stone wool products are the best. Third, refractory insulation with good hygroscopicity is also very important, it can keep your room drying for a long time , played the role of moisture-proof, and more capillary, the hygroscopicity is better.
- Q: Which refractory is suitable for the tunnel kiln?
- Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.
