Use
The company produces other kilns with the diameter1-5 meters, widely applies in the metallurgy, the chemical industry, bears professions and so on material, Ceram site, papermaking. This kind of kiln’s supporting is divided into two forms of rolls and skids, the transmission may use direct-current or the exchange frequency conversion velocity modulation, and has many kinds of form seals to adapt the different operating mode.
Our company could also meet different needs from different customer to produce Non-standard kiln.
Rotary kiln is composed of cylinder, gears, supports device, kiln liner and kiln tail sealing equipment, kiln head hood, and combustion.
Cylinder as heated pivoting part, made of high-quality carbon steel plate, is supported on the first or some gear in order to control the turning of cylinder. Gearing gyrate according to process-required rotating speed by ring gear in the middle of cylinder. Because of the need of installation or maintenance, bigger rotary kiln has auxiliary gears, which makes cylinder gyrate more slowly. To prevent cold air come in and dust overflow, the reliable kiln tail and head sealing equipment is installed on feed and discharge end.

- Q: What is the common inorganic fireproof and thermal inuslation matertial?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3 combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), sea capacity module and vitrified micro bead. (Hope I can help you! Hope you adopt. Thank you! )
- Q: What's the feature of construction external wall fireproof and thermal inuslation matertial?
- Building external wall fireproof thermal insulation material is made by stirring, casting, foam protecting and cutting with industrial by-product gypsum as the main raw material, adding sulphate aluminium cement, fly-ash, polymer additives and other materials. It has excellent properties of respiratory function , air permeability, water impermeability, recycling system data, wind load resistance, shock resistance, thermal insulation, fireproof and sound insulation.
- Q: Are fire materials poisonous after burning?
- Neutral refractory is mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick with chromium oxide as its main component has good corrosion resistance, but its thermal shock resistance is poor, and its deformation temperature is lower at high temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, good thermal shock resistance, high strength, resistance to acid and salt corrosion, especially weak acid has good resistance, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry.
- Q: Concrete composition and function of magnesia bond used in refractory
- Mainly high purity magnesia powder and silica fume, in accordance with the 4:1 ratio of the mixture, that is, we often use in the castable MgO-SiO2-H2O binding system! Compared with cement, the content of CaO is lower, the high temperature strength of the product is increased, and the slag corrosion resistance of the product is increased!
- Q: who knows the fire resistant level of fireproof gypsum board ?
- combustion performance of building decoration materials should be divided into four levels: A level, non-flammable; Class B1, flame retardant; B2 level, flammability; B3 level, flammable. Choose the materials above B1level. Thank you
- Q: How many refractories are there for boiler above 1200 ℃？
- Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
- Q: What are the types of steel refractory materials
- (1) clay refractory brick (2) high alumina refractory brick
- Q: The manufacturing technique of refractory material
- The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%～85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.
- Q: What kinds of fireproof materials does the safe use?
- Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- (1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof?performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
