New Prefabricated Kiln

 

For quick and easy installation on flat concrete floor, very compact with latest prefab kiln technology incorporated.

 

The prefabricated kiln is a small or medium size kiln which is fabricated in our factory and delivered in separate modules to be joined at the site.

 

To reduce the investment and operation cost, we built the prefabricated kiln with suspended kiln wall, which is supported by steel structure. Thus the wheel of the kiln car will be exposed in the atmosphere, the working tempeature of wheel is designed around 80°C and the requirement for lubrication will be much less.

 

The Unique Waste Heat Utilization system provides less power requirement and less fuel consumption.

 

The main parameters of one new concept kiln with daily output of 100T to be executed in 2010 are given as below for reference only: 

  • The designed sintering temperature: 1,670°C;

  • The designed limiting temperature: 1,800°C;

  • Output: 100T/day;

  • Total length: 40m (net width: 4.6m);

  • Product:  Calcined Bauxite, Synthetic Mullite, Homogenized Materials (Synthetic Mullite, Synthetic Corundum, and so on);

  • Fuel:  Coal gas

  • Fuel consumption:  30,000~33,000Nm3 of coal gas per day (its heat calorie value is about 2,700Kcal/Nm3), which is equivalent to 900Kcal per kg of calcined bauxite (Al2O3: 80~93%) at sintering working temperature between 1,650~1,670°C

  • Power consumption: 35~45 KWH

  • Firing period: 120 hours

  • Long firing time generating more corundum phase and few glass phase

Q:Pals who know something about fire resistant material please tell me how many types of refractory material there are
There are a variety of refractory materials, each of different use. It is necessary to make resonable classification for refractory materials so as to facilitate scientific research, rational selection and management. There are many kinds of classification methods for refractory materials, including classification based on chemical property, chemical mineral composition, production process, material form and other methods. 1, according to the capacity of fire resistance: ordinary refractory materials: 1580 degrees C ~1770 C Advanced Refractory Materials: 1770 degrees ~2000 degrees c: Classification according to product shape and size: standard 230mm×113mm×65mm no more than 4 scales
Q:How many types of special refractories are there?
Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
Q:Can anyone tell me what material the first rate fire resistant door is?
Material of Class A fire doors mainly are steel, wood, steel and wood, and other materials. Fire door is one of the measures of the building fire separation, usually used on the firewall, entrance and exit of staircase or tube well openings, which is required to hane the abilities of smoke insulation and fire insulation. Fire door plays an important role in prevention of the spread of smoke and fire and the reduction of fire loss. Therefore, we must have strict requirements. Fire doors are divided into class A, class B and class C, whose properties of fire-resistant thermal insulation and fire-resistant integrity should be no less than the following values: Class A should be1.50h; class B should be1.0h; Class C should be 0.5h. - stipulations in article 4.5.1.2 in "The New Standard of Fire Doors" GB12955-2008. I hope my answer can help you. Thank you.
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:What is the definition and classification of amorphous fire resistance materials?
9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
Q:What are the electrical fire protection materials?
Inorganic binder: Water glass, gypsum, phosphate, cement, etc.; Refractory mineral filler: Alumina powder, calcium carbonate, asbestos, perlite, cornstarch; the main purpose of electrical fire prevention board is to prevent fire and heat. The heat conductive plate will conduct electricity, leading to good equipment insulation and large superheating surface! ! ! ! Hope my answer will help you.
Q:What are the requirements of refractory temperature of refractory brick?
Refractory temperature of refractory brick is 1650 degree.
Q:What kind of refractory materials are used in metallurgy industry?
Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.
Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.
