Q: What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
I’d like to make supplements to upstairs that aluminum silicate refractory materials should be needed considering heat insulation.
Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
The material is very troublesome, it might crack horrendously if not baked well and all of them may be scraps after being took out from the furnace. Magnesia hydration is inevitable during the baking process. As volume expansibility of magnesite reaches 200%, so it is easy to crack. The key to bake is to quickly rule out the water vapor in furnace, especially within 150 degrees Celsius. After quickly ruling out the water vapor in furnace to avoid excessive reaction with magnesia of 150 degrees, it can be operated in accordance with convention. In addition, you should pay attention to the heat sources, for which i recommend electrical and coke to avoid generating a lot of water vapor during the natural gas combustion process which will worsen the situation.
Q: How to apply the alumina powder on refractories?
The most common one in use is the refractory bricks.
Q: What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
Q: What are refractory materials?
Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
Q: what are the types of piping insulation material fire?rating?
according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several grades grade A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk. 2, external wall thermal insulation materials, in accordance with fire rating, can be divided into1) grade A combustion performance thermal insulation material: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q: who knows the fire endurance of fireproof coating?
It's fire endurance is 3hours. Fire endurance test of certain building components showed by standard time temperature curve from the starting of fire to lose of supporting capabilities or its integrity or fireproof property. unit time is one hour.
Q: What are the requirements on fire resistance period of C-level fireproof glass?
It can be classified into three types in terms of fire resistance, Class A: The fireproof glass which meets demands of fire integrity and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.
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.
