Q:What are the types of steel refractory materials
(1) clay refractory brick (2) high alumina refractory brick
Q:How to detect the acid resistance of refractory? Is there any standard? Thank you
There is a standard. However, the range what you said is a little big, it's difficult for me to say. But though the scope is a bit big, it should be: You can check the industry standard network, to see whether you can check it.
Q:what's the standard of fireproofing material?
first, the classification of fire resistant levels of buildings, 1, the classification basis of fire resistant levels of buildings, the classification of fire resistant levels of buildings is one of the basic building fire protection technology measures, our national architectural design specification divides fire resistant levels of buildings into first, second, third and fourth class, first class ios the highest and has the most strong fire-resistant capacity, fourth class is the lowest and has the weakest fire-resistant capacity. Fire resistant level of buildings depends on the combustion performance and fire endurance of the components of the buildings. construction components refer to the wall, base, beam, column, floor, stair, suspended ceiling and other basic components of buildings. Combustion performance and fire endurance of building components are shown in table 4-11), the combustion performance of building components are divided into non-combustible component,hard-comnustible component,combustible component,according to their response to the fire. as for building components, non-combustible component includes wall column and base,etc; hard-comnustible component includes hanging bracket, suspended ceiling and internal pipe;combustible component includes doors and windows, suspended ceiling, decoration materials,etc.
Q:How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?
If there is only a small local, bake according to the overall it is really troublesome, water wall repair point of direct drive estimation problem is not large, the water wall itself is used to slag slag slag principle, can also play the role of refractory materials.
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.
Q:Why the refractories should be waterproof and wetproof
It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use
Q:What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?
Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories. The above is provided by the China Technology Department
Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:which kind of refractory is used in golden smelting furnace? How about his using temperature
generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.
Q:What are the standards of refractory concrete ?
Refractory concrete is generally divided into three categories: Light insulating concrete (for insulation); medium-quality refractory concrete (It is used for the parts where requirement of refractory temperature is not very high, and it can withstand a certain erosion of air); heavy refractory concrete (It is used for the parts where requirement of refractory temperature is fairly high, and it can withstand a certain intensity of erosion of air). It mainly depends on the design temperature and the using parts. There are a variety of raw materials, of which aluminum oxide is one of the most commonly used materials, others are alumina hollow ball, magnesium oxide, zircon, etc. It depends on the design temperature and the parts on use. Commercial concrete station generally can not produce it, instead it is compound by professional refractory concrete factories.
