- Q: Does anyone know the refractory temperature of fire-resistant glass?
- Ordinary glass will burst under sharp temperature difference of about 70-120 degrees and toughened glass of 200 degrees. It is not yet clear for the bursting temperature differences of the refractory glass. If the overall glass is heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
- Q: How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
- Q: What are the new refractories? What are the features? How about their application and development?
- In metallurgy, in what position should it be used, in order to make the best. Answers are as following. In iron, steelmaking or converter. When questioning, pay attention to the ways. Answers: Try to use synthetic refractory materials.
- 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 needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: What is required to do refractory material?
- But we can’t exclude that some products may contain a certain amount of metal materials: refractory material is non metallic materials whose physical and chemical properties make it suitable to be used under high temperature. Technically, it needs high purity raw material,high pressure molding, high temperature sintering to make refractory material. Refractory materials have two properties: first, the strong thermal shock resistance, second is slag resistance, the key is to look at what parts does it apply.
- Q: What are the main characteristics of the sic refractories?
- 1. The usge temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand the dramatic changes of temperature and have a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
- Q: what's the requirements of refractory for forge furnace?
- High temperature resistance, good slag resistance.
- Q: Refractory inquiries
- Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- (1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof?performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
