Q:What is the use of refractory?
Refractories mainly provide stable working environment for high temperature operation , such as metallurgical industry (steel ladle, hot-metal bottle, torpedo car and most places directly in contact with molten steel and iron), chemical industry (coke oven cokeing, dry quenching engineering) and building materials industry (lime kiln and glass kiln)
Q:Who knows about the grade C fireproof door materials?
There are no differences in the interior materials of the grade A , B and C fire doors, they all use fire rock wool boards. The only difference is the thickness of built-in fire rock wool boards. The rock wool boards' thickness of grade A fire doors is 52 mm, that of grade B is 46mm, and that of grade C is 40 mm.
Q:What is the acceptance standard of refractory?
Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
Q:What are the commonly used admixture for alumina-magnesia refractory? What are the impacts on its performance?
2, form Mg-SiO2 coagulation and combination, CA cement bond? Bricks can generally be made by combing with phenolic resin, castable use 1, combined with silicon powder; 3, can also combined with brine MgCl is binding agent
Q:Are refractory materials and fireproofing materials the same?
Refractories are generally used in the industry such as power plants, electric stove and industrial furnace. They include refractory bricks and insulation materials. Fireproof materials are generally used in building and they are fireproofing.
Q:Does anyone know the difference between refractory and thermal insulation material?
I will give you a relatively simple analysis. Refractory can bear above 1,200 degrees centigrade, but some refractory is not insulated. For example, refractory brick can be directly in contact with heat source, but it has little insulation effect. Refractory includes ceramic fiber, high silica and so on. And they can be also insulated. But insulation effect is not so good as insulation material. Insulation material generally can bear below 800 degrees centigrade, and it is large in thermal resistance, low in heat conductivity coefficient and high in porosity factor, thus reducing heat loss. Briefly speaking, insulated material is to store most heat, and just let a small quantity of heat run of through air, thus insulating heat. Refractory includes glass fiber, rock wool, aerogel blanket and so on.
Q:How to divide fire resistant level of fire door?
The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.
Q:what's the classification of fireproof materials?
Fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof panel, fire door, fireproofing glass, fire retardant coating, fireproof bag,etc Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
Q:How much is the content of boron carbide in refractory material?
Boron carbide is used in refractory material. For example, generally we could add 0.2% of boron carbide into magnesia carbon bricks. It is suggested that 0.5% is enough, because it has strong effect in boosting melt. It is said that 0.5% would be alright since boron oxide after oxidation belongs to material of low melting point, so the amount should be limited within 0.5%-1%,
Q:Who can tell me what is neutral refractory?
Neutral refractories refer to the refractory materials which will not react greatly with both acidic and basic slag at high tempreratures. Such as carbon refractories and chromite refractories. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc.
