Q:What are the applications of refractory in petroleum?
It can be used in transportation of natural gas, filler of chemical equipment, security, insulation or even building materials.
Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
I feel the concrete thickness should depend on the experience and the actual situation. As for the specific method, I also can't say too accurately. If it's ladle, it generally chooses alumina magnesia castable.
Q:Which are fire proofing thermal insulation materials?
Fire proofing thermal insulation materials include: fire proofing heat insulating brick, fire proofing thermal baffle, fire proofing thermal insulation paper, fire proofing thermal insulation felt, fire proofing blocking, fire proofing fiber bulker, castable refractory, etc. Yizhen Decoration wish you a happy life!
Q:What are the new types of refractories? What are the characteristics? Their applications and developments?
A new type of refractory materials are: A12O3-TiO2-SiO2 refractories, MgO-A12O3-TiO2 refractories, MgO-CaO-TiO2 refractories, MgO-SiC-C refractories, nanotechnology MgO-C brick, MgO-AL2O3-AIN refractories, MgO-La2O3 refractories etc..
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:Which brand of thermal insulating refractory is good?
Brands of thermal insulating refractory: 1, Armaflex(German brand). Manufacturer: Armacell thermal insulation materials (Guangzhou) Co., Ltd, Armacell thermal insulation materials (Suzhou) Co., Ltd. 2, Durkflex (American brand) Manufacturer: Durkee (Guangzhou) thermal insulation material Co., Ltd. Durkee (Wuhan) thermal insulation material Co., Ltd. 3, Aeroflex (Thailand Brand) Manufacturer: Aeroflex Polymer Technology (Shanghai) Co., Ltd.
Q:What material is used for making refractory stone bowl?
It can be natural stone or synthetic material (referred to as synthetic stone). If chosen improperly, some natural stones will separate out the minerals which cause gastrointestinal discomfort on sensitive people. Synthetic material has great output with relatively high safety and it is stronger than ceramic casserole. Now stone pot of synthetic material is mainly used in South Korea.
Q:Procedures for producing common refractory materials?
The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
Q:What is the magnesium carbon refractory?
The composition of refractory brick raw material There are many types of refractory brick raw materials, mainly divided into six categories: Soil, stone, sand, mineral, power and others. One of the original material, soil: Aluminum, kaolin, clay, diatomaceous earth The second raw material, Stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on.
