Dead-burned magnesite is selected from natural magnesite, calcined temperature and the shaft kiln. It is the material of ordinary magnesia bricks, shaped and unshaped refractory products.
Specification
Application
It is used for steelmaking furnace bottom and ramming furnace.
In the same condition, using manganese or silicon to deoxidize separately, the burn out rate are 46% and 37%, but it is only 29% if using manganese alloy to deoxidize. So, it is used widely to smelting steel and its output increases faster than ferroalloy's, so has become an indispensable composite deoxidizing and alloy additives in steel industry. The silicon-manganese which contains carbon below 1.9% still is used to produce medium/low-carbon ferromanganese and semi-finished products of electro silicothermic process manganese metal.
- Q: what's the application of fireproofing abs materials?
- fireproofing abs material is quite good, its fireproofing ability is quite good, now it's sales in the market is very well, you can purchase as you want.
- Q: What is the upper temperature limit for refractory materials?
- The key depends on what refractories you use
- Q: How much is refractory spraying coatings?
- This depends on whether you use the thin coatin or thick coating. Then it depends whether you use an aqueous coating or oily one. Usually thick aqueous coating is 2-3 dollars per kilogram. While the thin is six or seven dollars per kilogram. The oily coating is more than ten dollars. The prices obtained from the Internet is for reference only.
- Q: What is the principal part of silicious refractory material
- Silicon nitride and aluminite powder as well as dextrin
- Q: Concrete composition and function of magnesia bond used in refractory
- The first answer is 2 points, and the answer is accepted. You get a reward and 20 bonus points. Magnesia, magnesia brick, magnesia brick, magnesia brick, magnesia calcium brick, magnesia carbon brick
- Q: What refractories are resistant to fluorine gas?
- It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica?brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
- Q: What is the function of refractory in ceramics?
- In addition, the quality of refractory determines the finish and color of ceramic glaze.
- Q: how does the fire endurance of first rate fire resistant window?
- how does the fire endurance of first rate fire resistant window? I really don't know it and I need a specific direct and detailed answer!
- Q: How to make the service life of refractory materials longer?
- Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
- Q: who knows the fire endurance of fireproof coating?
- fireproof coating of different thickness differs in its fire endurance. Let me intrduce you as follows: The amount of time of 0.5 hours refractory thickness 0.45mm 0.79kg / m21 hr 0.9 mm 1.5kg / m21.5 hour 1.4 mm 2.3kg / m22 hr 2.0 mm 3.3kg / m22.5 h 2.8 mm 4.6 kg / m2
