 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's the refractory material in common use currently?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q:The development prospect of fire-resistant material
I also want to know, who can say, thanks all the way.
Q:Who knows the fire endurance of rock wool color plate?
Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof  Specification of Building Interior Decoration Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .
Q:Who knows about roof fireproofing materials?
At present, only phenolic foam boards can meet requirements. The test temperature can be 2,000 degrees, and there is no molten droplet during the tests and it can maintain integrity. heat conductivity coefficient: 0.03W / (mk), non-combustible, non-toxic, smokeless!
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
Q:What are the types of advanced refractory?
Divided into ordinary and special refractory two categories. Common refractories by chemical properties into acidic, neutral and alkaline. Special refractory are divided by the high temperature oxide, refractory compounds and high-temperature composite materials by its compositions. according to refractoriness it can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and premium refractory products (2000 ℃ above). The article can be divided into blocks (standard bricks, shaped bricks, etc.), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron carbide quality, etc.) and irregular shape (refractory clay, pouring materials and ramming mixes, etc.) According to the sintering process is divided into sintered products, cast products, melt blown products. The appearance is shaped or amorphous according to pH it can be divided into acidic, neutral and alkalinity according to basic operation mode, there are castable refractory ramming spraying materials, impressionable plastic material, coating. according to different components, there are clay, high alumina, corundum, spinel, magnesia, magnesium, calcium, magnesium aluminum quality,magnesia-chrome, silicon, etc.
Q:How to count the construction costs of refractories?
In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
Q:who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
Q:Which refractory is better for building 1500 degree kiln ?
High alumina brick or 99 alumina hollow ball brick is OK, which can withstand a temperature of 1600 ℃.
Q:The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.
3, the selection principle of antioxidant and its thermodynamic and kinetic mechanism31 selection principles of antioxidants:(1) according to the thermodynamic data and the conditions of use, the possible condensed phase and the vapor pressure of each gas phase are determined;(2) compare the size of each coacervation and oxygen affinity, and the possibility of reaction with CO.(3) the influence of various reactions on the microstructure of brick was analyzed.The thermodynamic and kinetic mechanism of 3.2 antioxidantsFrom a thermodynamic point of view, at the operating temperature, the additives or additives that react with carbon react with oxygen more closely than carbon and oxygen, giving priority to carbon oxidation, thus protecting carbon;From the analysis of dynamics point of view: the compound additive with oxygen and carbon monoxide reaction changed the microstructure of carbon composite refractory materials, such as increasing the density, blocked pores, hinder the diffusion of oxygen and reaction products.
