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: The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
- Yes. After moulding by casting in the firing of 1450 ° degrees.
- Q: whether the fire resistant level of aerated concrete building blocks can reach the grade one?
- Aerated concrete building blocks is made by calcareous materials (such as cement, lime) and siliceous material (such as sand, fly ash, slag), adding aluminum powder ingredients as filling agent, by mixing with water, casting molding, gas - expansion, raising the pre-cut, and then the high-pressure steam curing of silicate building blocks. when aerated concrete is at the temperatures below 600 ℃, the compressive strength will be increased slightly, when the temperature is at about 600 ℃, the compressive strength is close to the compressive strength at normal temperature, so the aerated concrete, as building materials, the fire performance can meet the national fireproffing safety standards level.
- Q: What kind of material is refractory fiber?
- Refractory fiber is good infrared radiation material with good thermal capacity and infrared heating effect. The use of firefractory fiber products can effectively save energy. It is an ideal energy-saving material. Practice has proved that using refractory fiber in continuous industrial heating furnace can save energy of over 15%, and using it in interval industrial heating furnace, it can save energy of more than 30%, while increasing productivity and improving product quality. And make the furnace structure light, large-scale with good comprehensive performance. Refractory fiber is soft and flexible and it is also ideal sealing material. As it has good insulation, sound absorption, anti-oxidation, oil and water resistance and easy construction, it is widely used in metallurgy, building materials, petroleum, chemical, shipbuilding, electric power, aerospace and other fields.
- Q: Which schools are the best schools in the world for learning knowledge about refractories?
- Wish it helps you out.
- Q: What's the material of electrical fire prevention board?
- Industrial electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface! ! ! !
- Q: What parts of cement kilns are refractories used on?
- These parts are decomposition furnace, smoke chamber, kiln, kiln hood, grate?cooler, tertiary air duct and coal pipe.
- Q: What types does refractory floor include?
- There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
- Q: What kinds of refractory materials that can resist 3,000 Celsius degree?
- steel fiber reinforced spalling resistant bricks, phosphate bonded high alumina brick with high strength and wear-resistance, and high R.U.L bricks and composite bricks
- Q: Can the teflon material resist fire?
- Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
