What is fused magnesite?
Fused magnesite is produced by high quality magnesite through electro- fusing, After melting, the SiO2 of material moves to the surface for the difference in the specific, so it has well grown crystals, well crystal perfection and structure homogeneity, excellent chemical stability, good corrosion resistance to slag and high strength at high temperature.
Where to apply fused magnesite?
It is widely used for gunning materials, fused magnesite ramming material, magnesite brick, magnesite chrome brick, vacuum and vacuum induction furnace, electric arc furnace refractory lining, magnesia crucible, furnace and a variety of refractory, such as large scale glass furnace by floating method, electrical furnace, convert furnace, house hold electrical appliances as electrical insulating materials,
- Q: Who knows about roof fireproofing materials?
- Roof thermal insulation materials are various which generally can be divided into two categories, namely inorganic and organic materials: Inorganic materials are expanded perlite, aerated concrete, rock wool, glass wool, etc. Organic materials are styrofoam, polyurethane?foaming?plastic and so on. A. common roof thermal insulation materials 1. the expanding polystyrene board (EPS) has good thermal insulation performance, and cheap price but poor intensity with heat conductivity coefficient of 0.038-0.041. 2. extruded polystyrene board (XPS) has better thermal insulation performance and high intensity but an expensive price with heat conductivity coefficient of 0.028-0.03. It is moisture resistant but needs treatments on surface in construction. 3. rock wool board, with heat conductivity coefficient of 0.041-0.045, is fireproofing, fire?retardant. It has a good hygroscopicity performance but is poor in thermal insulation. 4. gelatine powder polyphenyl granule heat insulating slurry, with heat conductivity coefficient of 0.057- 0.06, has a good flame resistance performance, but the results of recycling and thermal insulation are unsatisfactory. It has high construction requirements. 5. polyurethane foaming material, with heat conductivity coefficient of 0.025-0.028, has good waterproofness and thermal insulation performance, as well as high intensity, but it is expensive. 6. perlite and other slurry, with heat conductivity coefficient of 0.07-0.09, have good flameproofness and water-absorbing ability but are poor in thermal insulation and thermostability.
- Q: what's the fireproof levels of fireproof and thermal inuslation matertial?
- 1, organic materials: B level material is flammable, B1 level material is flame retardant. 2, inorganic materials: Grade A flame-resistant materials are divided into three classes and two kinds of materials.
- Q: Who can tell me about the foundry refractory materials?
- The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming?mass, castable refractory, refractory cement, silica sand, magnesite, etc.
- Q: What are the physical properties of refractory material?
- The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
- Q: What is the use of refractory?
- It is used as a protective layer inside the high-temperature, high-corrosion, high-washing, easy to be wore equipment and as an insulation layer outside equipment.
- Q: What are the models of bauxite with high alumina?
- China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
- Q: What are the fire resistances of grc partition panels?
- It's ok, calcium silicate itself is a non-combustible material. Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls. We can talk about it in detail.
- Q: How long is the duration of fire resistance that fireproof door of level B can endure?
- The national standard for fireproof door of level B is 1.5h, which must be achieved. The data GB12955-2008 means that the door leaf of raw material is 0.8mm-1.2mm in thickness and door frame is 1.2mm-1.5mm in thickness. And other metal melting temperature shall not be less than 950℃, the duration of fire resistance shall not be less than 0.9 hours. Fire department will check and accept based on the manufacturer's inspection report, so you have to refer to manufacturer's inspection report if you want to know more in detail.
- Q: Who can tell me the properties and classification of insulating refractories?
- Insulation materials can be classified according to service temperature, production process and application fields.
- Q: Who knows what fire heat preservation material are there?
- Organic material, polystyrene board, plastic extruded board, phenolic resin. Sea capacity module (fire insulation materials fire performance can reach the B1 level, thermal conductivity is only 0.028w\m - K is a good choice, class A fireproof materials now is the mainstream rock wool (mineral wool is wool). A1 fire resistance The largest manufacturer is Thai stone rock wool Co. Ltd.
