Description of Castable Refractory Materials

Castable for ladle is bagged particle, ash grey. It is used as lining material for ladle with the property of high refractoriness, long service life, reduction of materials and manual operation.

Features of Castable Refractory Materials

Easy to operate: times and labor saving, shorten the work time, reduce work strength of workers.

Superior property: resistant to scour and erosion of molten iron slag, good thermal shock resistance, non-stick of iron slag, tiny linear variation, no cracking, and easy to break up.

Extend service life: high technical content, good property in using.

Long service life: can be used for the number of 800-1200

Q:who knows the uses of refratories?
Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !
Q:What 's the highest temperature can magnesium plate glass resist ?
You only need a fire-resisitance board thicker than 10 mm, remember to add more perlite as filler during production, 12 mm board is 80 yuan. . . .
Q:Who knows the fire endurance of B-level fireproof doors and windows?
Rock wool board of B-grade fireproof doors keeps 46mm in thickness, doors that are generally used in relatively common fire fighting access, while A-grade fireproof doors are generally used in machine rooms, warehouses, oil depots and other important fire fighting access and flammable and combustible pulbic places. B-grade fireproof doors are more widely used than A-grade fireproof doors.
Q:what are the types of piping insulation material fire rating?
Pipe insulation material Fire rating: heat conductivity coefficient(at room temperature) 0.025 grade non-combustible Class A low temperature bending ≤ 5000 breaking elongation 5,000 specifications 5000 anti-bending strength 5000 compressive strength 5000 special brand of high use temperature -250 ~ 150 ℃ core material, phenolic foam, form, stratiform, shape,flake.
Q:What are the requirements on fire resistance period of C-level fireproof glass?
Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance.
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's the fire endurance of A grade fireproof glass curtain wall?
According to the latest requirement, fire door has three types of FMA, FMB and FMC, of which A, B, C refer to the class. Take FMA as an example, it refers to A class fire door (namely thermal insulation fire door). The fire endurance of these three types all can be 0.5h, 1.0h, 1.5h, 2.0h or 3.0h, and the specific fire resistance time needs to be determined by the design. Generally the design drawing will make clear of it. As to A class fire door, its fire endurance is 1.5h.
Q:Physical and chemical indicators of various refractory.
it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
Q:Is aluminium oxide refractory material?
Aluminium oxide with 2030ºC melting point is a kind of good refractory material. It can be used as analytical reagent, dehydration and adsorbing material of organic solvent, catalyst of organic reaction, abraser,polishing agent, raw material of aluminum smelting technology and refractory material. Hope it is helpful to you.
Q:who knows the fire endurance of fireproof coating?
It's fire endurance is 3hours. Fire endurance test of certain building components showed by standard time temperature curve from the starting of fire to lose of supporting capabilities or its integrity or fireproof property. unit time is one hour.
