Light Burnt Magnesium Oxide Ball
1.Stable quality performance
2.Protect the furnace
3.Reduce consumption

Advantage and Application

The advantage of this new material is its high MgO content as well as burned substances,which can also avoid with in furnace decomposition burning so as to save much energy. By this new means,it will do a lot good for improving the rate of scrap steel and sand melting. It is used for converter steel making,through the splashing cross to protect the furnace,which can raise the furnace life.

Because slag splashing furnace protection requires appropriate viscosity and refractoriness, reasonable slag content is the key for slag splashing furnace protection. Common slag can’t be applied to slag splashing furnace protection directly, a certain amount of caustic calcined magnesia balls need to be added to adjust, meanwhile replacing the usage of dolomite, reducing the quantity of slag, increasing MgO content in slag. Because MgO is a mineral with high melting point of 2800°C, by increasing the MgO content in slag, the viscosity of slag and refractoriness will also be increased, which will make it easier for the slag combine together with the linings and form an effective slag protection layer, thus improving the service life of linings and reducing consumption.

Q:How is grade of fire endurance divided?
Fire resistance level is mainly decided according to the importance and function of the building. For example, very important buildings are set as the first level, and the less important is the second level, and so on.
Q:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:Who knows the new fireproof and thermal inuslation matertial?
Ceramic foam insulation board, XTP vacuum insulation panels and a variety of composite insulation panels, etc. Relatively speaking, the inorganic insulation board is a trend. In terms of the overall performance, the cost performance of the foam insulation board is higher. XTP has the best performance, but with a little trouble in construction. Because of the vacuum characteristics, transportation and installation process should be very careful.
Q:What are unshaped fire-resisitance materials?
Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
Q:Fire resistance and evaluation of refractory for casting
The products to be tested are broken and ground, adding organic binders (usually dextrin) that do not affect the refractoriness. Water is used to make standard sized test cones, as shown in figure 1-2-1. Test cone is positive, three edge cone, the bottom side length of 8.5mm, the top side length is 2mm.Test, the equivalent of high standard cone refractoriness of the 2 products to be high, No. 1 and No. 1 high temperature low standard cone of each one, and the 2 to be tested in accordance with regulations frustum cone plug made of high aluminum material, a cone prism and vertical 8 degrees. 1 degrees tilt angle. Then, the cone is heated in a high temperature furnace. When the test cone with a high temperature and bending down to the standard cone top contact cone, the high standard cone refractoriness refractoriness is running.
Q:Does anyone know the refractory temperature of fire-resistant glass?
Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. (I hope this answer can help you!) Hope you adopt !)
Q:What is the type of heat resistance property of high temperature electric furnace ?
According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃
Q:What do refractory materials include?
What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
Q:Development trend of refractories
Mullite Matrix clinker. There are higher requirements of kaolin and refractory annded life, it should be able to grind medical industrial raw materials alumina, vacuum extrusion molding, high temperature roasting and smelting from unshaped refractory material a good thermal mechanical properties in the kiln and has good application prospect; 2, Dong Qingshi clinker. With kaolin and magnesia as raw materials, wet grinding, vacuum extrusion, and then high temperature calcination, furniture has a very good prospect; 3, magnesium calcium sand. Because of the development of clean steel, low carbon steel, high oxygen steel and stainless steel, the basic importance of free calcium oxide refractories is supported; 4, fused eutectic composite. Bauxite based fused corundum, bauxite based fused mullite, bauxite based fused mullite zirconia, fused corundum zirconia fused zirconia, Magnesium Oxide and other materials have been developing rapidly; 5, high density spherical hollow mullite aggregate. The wall thickness of the shell of the 0.2 - 1.5 - 5 mm, diameter 40 mm, smooth surface, can not be uniform, spherical shell, this may be a double, a prominent part of the surface can be dense, can also be used for hollow casting material, not only can improve the insulation performance of the material, in order to reduce the volume density. Instead of destroying its strength.
Q:What refractories are accessible with ease in daily life?
Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.
