- 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: Are the specification of fireclay bricks and ordinary clay brick the same?
- The standard size of refractory bricks in our country is: 230mm × 114mm × 65mm; ordinary brick: 240 ×115 ×53, building blocks: (it is divided into blind hole and via) 240×390×190, 240×190×190, 240×90×190, 190×190×190, 190×390×190, 190×190×190, 190×90×190, 140×390×190, 140×190×190, 990×200×400, 0×390×190, 90×190×190, 90×90×190. Another is interlocked hollow block : 90×200×400，90×200×245，90×200×200，90×200×100，90×200×290，150×200×275，150×200×200，150×200×100，150×200×290.
- Q: What's the function of aluminium dihydrogen phosphate on the refractories?
- Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
- Q: What are the construction measures of refractory material in winter? Please descriptive briefly.
- The temperature is low in winter, so refractory bulk materials should be stirred evenly on time to avoid freezing.
- Q: What are the insulation fireproofing materials?
- Insulated shoes, insulated gloves, tape (cloth, plastic, as well as waterproof) yellow wax tube, mouth care, fireproof (ie asbestos cloth is sold by jin) there is pressure-caps black tape, waterproof tape ,casing. There are glass fiber needle felt is widely used in electrical, chemical, construction, transportation, automotive and other industries interlayer insulation and silencer system, and used as an insulating fireproof material.
- Q: What refractories are accessible with ease in daily life? This material is suitable as a disposable mold and crucible for melting brass.
- There are many refractories in daily life. Such as the lining of furnace! And refractory cotton ... If you want to melt brass, you need to resort to professionals! It's rare in daily life to find out those molds that can be made by ourselves. You can buy a corundum crucible in the neighbouring laboratory equipment market! Remember that brasses' melting point is at above1000 degrees, so the material must have refractoriess of 1000 degrees.
- Q: Refractories for iron-making blast furnace?
- Cement kilns?
- Q: Can anyone tell me what is a high alumina refractory?
- Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
- Q: what textures of furnace refractories are good?
- First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
- Q: Who knows about the types of Dalian thermal insulating and refractory materials?
- There are mainly following types: rock wool series, rubber and plastic series, glass wool series, mesh series, ventilation series, mortar series, extruded sheet series, geothermal series, insulation supporting pin series, glass silk cloth series. I hope my answer can help you.
