Refractory 90percent MgO Dead Burnt Magnesite Price

Dead Burned Magnesite

Description

Dead Burnt Magnesite is produced in the Rotary Kiln by sintering raw magnesite at a controlled temperature of 1750 degree centigrade and its chemically inactive. Dead Burnt Magnesite is consume almost exclusively in the production of Refractory Field.

Dead Burnt Magnesia Application:
1. Refractory Industry for manufacture of Basic Refractory Bricks .
2. Manufacture of Ramming Mass composition, Fettling material and Magnesite Mortar.
3. It is used in SLAG beneficialness and in SLAG splashing in Arc Furnaces.
4. It is also used as a coating material in Steel Industry.

Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?: Fire endurance (h): Under the condition of standard fire resistance test, the time when the building components, accessories, or structure is subjected to fire to the time when they loose stability, integrality or thermal insulation is called fire endurance which is showed in time. Steel is the kind of building material that is nonflammable with many properties of seismic resistance and bending resistance. In practical applications, steel can improve the load capacity of buildings in a relative way, meet the needs of buildings design, beauty and mould, and it can also avoid the defects of poor flexibility and tensile strength of buliding materials like concrete. Therefore, steel is quite popular in the construction industry, and it is widely used in single-story or multi-storey skyscrapers, plants, warehouses, waiting rooms and airport terminals, etc. However, as a kind of building material, it has some unavoidable defects in fire prevention. That is its mechanical properties like yield point, tensil strength and elasticity modulus will decrease dramatically with the rise of the temperature.

Q: How long is the fire resistance time of the AAAfire resistance rolling shutter door?: How long is the fire resistance time of the AAA fire resistance rolling shutter door?

Q: What is fireproofing material? Are fireproof materials the same thing with thermal insulation materials and refractories?: Fireproofing material is inorganic board, while thermal insulation material belongs to organic board. Fireproof material can also preserve heat, but it is not as good as thermal insulation material in this aspect.

Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T: o

Q: What refractory material does cupola lining use?: Refractories for ehongtianlu, Yong, eajliao, najhuo cupola, refractory (refraetoriesfo:Cupola, furnace) masonry cupola and related parts. The utility model also discloses a heating furnace, which is a thermal equipment for melting pig iron in the casting industry and certain steel smelting plants. The working temperature of the guard is usually 1400 ~1 stone.. C.

Q: What are the common refractory insulation cotton material?: High aluminum, clay brick, aluminum silicate fiber module and so on, inorganic types are glass wool, rock wool, foam glass etc.. Organic: the best one is phenolic foam, compround phenolic foam cement layer is a-level. Aerated concrete and other refractory thermal insulation material mainly refers to the inorganic thermal insulation materials and compround thermal insulation material, expanded perlite, foam clay It is applicable for buildings that have high requirement for fire proof level, foamed concrete, volcanic ash glass.

Q: What are first rate fire resistant window materials?: Natural environmental protection, non-poisoned, non-peculiar smell, non-radioactive; non-combustible, fireproofing, moisture-proof, corrosion-resistant; easy construction, lightweight, high strength, www. jsxsmy.

Q: what's the requirements of refractory for forge furnace?: operating temperature of forge furnace is 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. general requirements for the properities of refractory: 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 are the specifications of fireclay bricks?: Specifications of fireclay bricks are shown in the figure;

Q: What are the main materials in concrete fireproofing material?: fireproofing materials mainly consist of class A incombustible?material and class B1 nonflammable material. Class A incombustible?material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
