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

Rotary / Shaft / Round Kiln Calcined Bauxite

Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?: It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.

Q: What kind of material is refractory fiber?: Refractory fiber is good infrared radiation material with good thermal capacity and infrared heating effect. The use of firefractory fiber products can effectively save energy. It is an ideal energy-saving material. Practice has proved that using refractory fiber in continuous industrial heating furnace can save energy of over 15%, and using it in interval industrial heating furnace, it can save energy of more than 30%, while increasing productivity and improving product quality. And make the furnace structure light, large-scale with good comprehensive performance. Refractory fiber is soft and flexible and it is also ideal sealing material. As it has good insulation, sound absorption, anti-oxidation, oil and water resistance and easy construction, it is widely used in metallurgy, building materials, petroleum, chemical, shipbuilding, electric power, aerospace and other fields.

Q: The difference between refractory and thermal insulation material: Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.

Q: The development prospect of fire-resistant material: Exported bulk material amounts to exported raw material/ To protect domestic resources, many countries have set linitations on the magnesium content in shapeless refractory material and lisences.

Q: What is the fire endurance of fireproof glass cotton?: Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.

Q: Does anyone know what is a lightweight refractory material?: I am ignorant of this!!

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 is the fireproofing requirements of external wall thermal insulation materials?: in the 2011 and 2012 revised version of "Fireproof? Specification of Building Design" in China, the external insulating layer of above 50 meters (approximately 16 layers) of the housing must use the level A material. The latest draft for approval is not so strict, above 100 meters (about 33 layers) only use level A material. The manuscript of "Building Regulations" is also regulated building's external wall thermal insulation materials in the crowded places should be level A. Except the residential buildings and the buildings in the crowded places, the height of other buildings is greater than 50 meters, combustion performance of insulation materials should be level A; the height buildings is greater than 24 meters but not more than 50 meters, combustion performance of insulation materials should not be lower than level B1. "Building Regulations" manuscript should relax the rules on the aspect of protective coating in level B1 and B2 insulation material. The outer of level B1 and B2 level insulation material must use incombustible?material as protective coating, its thickness is changed from the original 10 cm to 5 cm. Given certain conditions, I feel you can use TDD exterior wall thermal insulation decoration integrated rock wool board for construction, which is level A fireproofing with a short construction period and good thermal insulation properties. I hope I can help you!

Q: Introduction to refractory material: The best way to learn is on-site contact. If for produing purpose, it is better to ask teh leader of a plant. If for application, go to steel mill (cement plant, glassworks, etc.) to learn and look up information. Theory alone is of no help.

Q: Is it necessary for the frame of glass fireproof door to be crammed with fire-proof material?: Close the door , and check if the gap is normal, whether the hole and the door leaf are in the same plane, and whether the door leaf has tendency to fall down. Fire resistance steel door——means that use a cold rolled steel sheet as door frame, door plank and framework, and stuff a door leaf with incombustible material.
