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.It is made from high quality magnesia and high purity magnesia-dolomite clinker in appropriate granularity ratio, it has good sticking ability, low rebounding rate and high abrasion-resistance
Usually it is used for converter gunning repairs
- Q: Can anyone tell me what is A-leve fireproof material?
- What you say is probably palstic! B-level means the fireproof rating is at B1-level because palstic material doesn't belong to fireproof materials. It only is fire?retardant. When wholesaling all kinds of insulation materials and construction, it need tos look at the names. B1-level refers to the fire endurance rating of the fireproof material, which is determined according to the fire resistance of the material. In addition, different parts of the material have different fire endurance ratings! You can download a "Specifications of Fireproof Design for Buildings" for further information!
- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
- Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
- There are many kinds of raw materials used, three, two aluminum oxide is one of the most commonly used raw materials, as well as alumina, hollow ball, Magnesium Oxide, zircon, etc., or the specific design temperature and the use of parts.
- Q: Do you know the refractories?
- Acidic material products: these products to quartz (SiO2) as the first phase, SiO2 is an acid oxide, helped named. Brick is representative of the product acid material; semisilica brick, alkali proof brick, acid brick in SiO2 content of 60% to 80%, is a semi acidic material.
- Q: How many types of special refractories are there?
- Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
- Q: What do we mean by saying that a ladle cover knots, elbow knots, blowpipe knots in refractory materials? What is the “knot”?
- Blowpipe is also the construction of unshaped refractory materials. Refractory material for ladle cover is light weight heat insulation refractory material. What you said that the construction of bend out refractory materials in some steel mills called "knot".
- Q: What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
- The material is very troublesome, it might crack horrendously if not baked well and all of them may be scraps after being took out from the furnace. Magnesia hydration is inevitable during the baking process. As volume expansibility of magnesite reaches 200%, so it is easy to crack. The key to bake is to quickly rule out the water vapor in furnace, especially within 150 degrees Celsius. After quickly ruling out the water vapor in furnace to avoid excessive reaction with magnesia of 150 degrees, it can be operated in accordance with convention. In addition, you should pay attention to the heat sources, for which i recommend electrical and coke to avoid generating a lot of water vapor during the natural gas combustion process which will worsen the situation.
- Q: How to deiron refractory?
- Our company uses magnetic separation method.
- Q: What is the magnesium carbon refractory?
- The composition of refractory brick raw material There are many types of refractory brick raw materials, mainly divided into six categories: Soil, stone, sand, mineral, power and others.

- Q: What are the main materials in concrete fireproofing material?
- it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )
