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:What's the fire resistance test method of doors and roller shutters?
- Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
- Q:What are some of the new refractories and what are their characteristics?
- Refractory common AZS refractories are often used brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, aluminum oxide, beryllium oxide and other refractory materials, Magnesium Oxide
- Q:How long is the fire-fighting time of A class fire resisting window?
- Duration of fire resistance of A class fire resisting window is not less than 1.2 hours; B class window is not less than 0.9 hours. And when install fire window, you must use Level to correct or use hanging line method to correct verticality of four directions, making its same horizontally anf vertically. Window frame must be integrated with the building, using wooden or metal parts connected to the wall. After steel frame is installed, cement mortar must be watered between window frame and wall , and is maintained more than 24 hours before normal use.
- Q:What are the materials for refractory materials? What are their names?
- High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
- Q:Which manufacturers have the best fire-proof materials with light weight?
- Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical?equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.
- Q:What's the refractory material?
- Main components of basic refractory are magnesium oxide and calcium oxide, and magnesia brick is commonly used. For the magnesia brick with magnesium oxide content of more than 80%-85%, it has good resistance to basic slag and scum, and it has higher refractoriness than that of the clay brick and silica?brick. It is mainly applied to the open hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting equipment and some high-temperature devices.
- Q:Which kind of furnace hearth refractory is better?
- Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
- Q:How many external wall thermal insulation fireproof material are there
- Class A exterior wall insulation: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic foam, foam glass
- 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 is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. Fire resistance rating of the building is divided into four levels. Standard of fire resistance rating is determined by the combustion performance and fire resistance of the main housing member. Level one or two are in accordance with the Article 1.0.2 in this specification.
