Dead burned magnesite- DBM-is produced using selected natural magnesite that is purified and is calcined in a shaft kiln.The final product is used for electric furnacefloors and furnace liner tamping.
Main products level :
0-1mm;1-3mm;3-5mm;0-10mm;0-30mm
50 to 325mesh (90% through)
Product feature:
high temperature performance and high-density, strong anti-permeability ability and easy to rapid sintering, very thin sintered layer,good thermal shock stability, strong slag-resistance, long service life and so on.
Product function:
Apply to the construction of bottom and wall of all kinds steel making electric arc furnace and ferroalloy smelting furnace for hot charging of hot metal and second hand steel
Product usage:
Mainly used in producing common magnesite brick, magnesite aluminum brick, magnesite chrome brick, gunning mix, hot patching mix for converter and EAF ect .
Product Advantage:
Our factory produce the products of the Dead-burned magnesite are selected natural magnesite, it is produced by mine-selecting, purifying, calcimine in shaft kiln. It is an ideal material for unshaped refractory material, the final products are used in open hearth furnace, electric furnace bottom and furnace's lining tamping.
- Q: What is the importance of silicon powder in refractory processing?
- in amorphousness it is mainly the mobility
- Q: What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q: Selection of refractory materials?
- Acid refractory with silicon oxide as the main component, are commonly used in brick and clay brick. Silica is silica containing more than 93% silica products, raw materials used in silica, silica and other waste, the acid resistance of slag erosion ability, high load softening temperature, volume shrinkage after repeated burning, or even a slight expansion; but it is vulnerable to the erosion of basic slag, low thermal shock resistance. The brick is mainly used for thermal equipment of glass furnace, coke oven, acid furnace etc.. Clay brick with refractory clay as the main raw material, containing 30% to 46% of alumina, weak acid refractory material, heat shock resistance, resistance to acid slag, widely used.
- Q: What are the characteristics of the carbon composite refractories?
- The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag
- Q: Does anyone know about the fire resistance period of thin fireproof coatings?
- The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- The most commonly used ceiling decoration materials rates B1, including gypsum board, fibrous plaster, cement particle board, mineral wool sound-absorbing panels, glass wool decorative acoustic?panel?absorber, perlite decorating acoustic board, nonflammable plywood, nonflamable medium density fiberboard, mineral wool decorative board, flame retardant wood, aluminum foil composites, flame retardant phenolic plywood, aluminum foil glass fiber reinforced plastic composite materials. The fire gypsum board fire rating can reach A. Of course, many of the suspended ceiling gypsum board of inferior quality rates below B1. plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. plaster board mounted on steel stud can be used as A level decoration materials. in accordance with the national fire safety rules on fire durance of walls and ceilings and other components. we can not simply say whether a piece of gypsum board can meet the requirements.
- Q: Fire insulation and fireproof insulation board materials What is the difference in performance?
- Fireproof materials and insulation materials, refractories not the same thing, but some insulation materials are fire resistant and refractory. Fireproof material is a synthetic material characteristics of fire resistance or the material itself is a high temperature resistant, flame-retardant. Fireproof materials are mostly used for construction, playing an important role in fireproof today in various forms.
- Q: Do you know where I can buy refractories?
- You can buy refractories in these places: 1. Addresses of refractory factory: No. 57, Qingshan District, Wuhan 2. Address of Qingshan refractory factory in Wuhan: Special NO.1 Xingli Road Hongshan District, Wuhan 3. Address of Xinghuo refractory factory in Hongshan district: No. 34 Qingshan District, Wuhan 4. Address of Henao refractory factory: No. 78 Jiangxia District, Wuhan
