$Tabular Alumina For Refractory With Good Delivery$

Q:How should refractory cement be used?: How to use refractory cement? How to use refractory cement? Thank you.

Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?: Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.

Q:What is the upper temperature limit for refractory materials?: The key depends on what refractories you use

Q:What kind of refractory materials are used in metallurgy industry?: Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.

Q:What are the requirements of the performances of brasque refractory?: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down But only refractoriness can not fully describe the refractories, 1580 ℃ is not absolute. Refractory is now defined as material of physical and chemical properties allowing to be used in high temperature environments. Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.

Q:What are the differences between intensive refractory busway and other busways?: Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities, replacing the fire-resistant cables to transmit and distribute power .

Q:Who can tell me about the foundry refractory materials?: The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming?mass, castable refractory, refractory cement, silica sand, magnesite, etc.

Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?: Fireproofing doors can be divided into Class A, Class B and Class C by the fire endurance, the fire endurance is seperately not less than 1.20h, 0.90h and 0.60h. Fireproofing glass is a kind of special glass which can retain its integrity and insulation in the prescribed fire test, it can be divided into three categories according to fire resistance rating: class A is the fireproofing glass with refractory integrity and refractory thermal insulation. Such glass has the properties of transmittance, fireproofing (smoke insulation, fire insulation, heat radiation shielding), sound insulation and shock resistance, which is suitable for architectural steel and wood fire doors, windows, partition walls, daylighting?roof, ceiling?screen, perspective floor and other building components required both transparent and fireproofing. Class B is a fireproofing glass with refractory integrity and thermal radiation intensity. Such fireproofing glass is mostly composite fireproofing glass with transmittance, fireproofing and smoke insulation. Class C is a fireproofing glass with refractory integrity. Such glass has the features of transmittance, fireproofing, smoke insulation and high strength. it can used in partition wall, fire window and outdoor curtain wall without the thermal insulation requirements. fireproofing glass can be divided into composite fireproofing galss and monolithic fireproofing glass by the structure.

Q:What substitutes are available for high-end refractories in addition to zircon sand?: Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..
