Fused magnesite chrome sinter

Finished Fused Mag-Chrome is made of high-quality chrome concentrate and high purity magnesite at accurate proportion, adjusting Cr2O3 content from high chrome to low chrome, in order to achieve low impurity content and high bulk density, as well as meet different needs. after molding into brick with our clincker, it is widely used in secondary refining device for RH,VOD,AOD and non-ferrous metallurgical furnace.

Q: What are included in roof thermal insulation fireproofing material?: Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire?retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.

Q: How to divide the fire rating standards of insulation materials?: 1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1. Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.

Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?: glass

Q: What is required to do refractory material?: Can you be more specific about what aspect?

Q: Can anyone say something about what A-level fire-proof decorative material is?: Combustion performance rates of decoration materials ratess combustion performance of decoration materials A incombustible B1 flame retardancy B2 flammability B3 high flammability The B1 rate combustion performance of gypsum plaster board and mineral wool acoustic panel absorber installed on steel joist can be used as A-level decoration materials. Inorganic decorative coating applied on the A level substrate can be used as A level decoration materials. Hope you adopt

Q: What is fire retardant coating mainly used for?: The functions of refractory coating are as follows: 1. Non-intumescent fire retardant coating is mainly used for the fireproofing of wood, fiber board and other materials, and it is used in the surfaces of wood truss, roof, doors, windows and etc. Second, the intumescent fire retardant coating can be divided into non-toxic intumescent fire retardant coating, expansible fire retardant coating emulsions, solvent-based fire retardant coating. 3. Non-toxic intumescent fire retardant coating can be used to protect cables, polyethylene pipes and insulation board. 4, The expansible fire retardant coating emulsion and solvent-based fire retardant coating can be used for fireproofing of buildings, electricity power, and cables. 5. New fire retardant coating: Transparent fire retardant coating, water-soluble intumescent fire retardant coating, fireproof emulsion paint, polyvinyl acetate emulsion fire retardant paint, water-soluble intumescent fire retardant paint drying at room temperature, fire insulation coating polyolefin fire retardant coating, modified high chloropolyethylene fire retardant paint, chlorinated rubber fire retardant coating, firewall coating, intumescent coatings, wire and cable fire retardant paint, new fire retardant coating, casting fire retardant coating and so on.

Q: Classification of porosities in refractories and their effects on properties: The first two types of stomata are commonly examined, known as apparent porosity.

Q: Can anyone tell me what is the material of which the mould for refractory is made？: I can make the mould and give you a discount. If necessary, you can contact me at 261240643 (qq).

Q: Where is the development of refractory industry?: Continuous casting system varieties used in refractory materials include: (1) ladle refractories -- ladle lining, permanent lining, ventilation components; (2) tundish refractories -- linings and coatings, insulation board, cover; (3) functional refractories -- non oxidation casting with long nozzle, immersion nozzle, stopper, sliding gate; (4) purifying molten steel with ceramic purifier, slag dam, alkaline coating and horizontal continuous casting for separating ring gate, etc..
