Light Burnt Magnesium Oxide Ball
1.Stable quality performance
2.Protect the furnace
3.Reduce consumption
4.MGO:65%

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:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
Q:How to choose thermal insulation materials for flood heating?
How to choose the appropriate thermal insulation materials: 1, Thermal insulation material shall have a small thermal conductivity, good thermal insulation properties. Besides, that also depends on whether the specific temperature changes of in the insulation materials' working environment can ensure the material has good thermal insulation. 2, when purchasing, we must be make sure it is light, and loose enough. These heat insulating material can not only afford bracket, and can also increase the heat transfer performance of the heat insulation material. prevet water penetration. Waterproof function should be soild, even if it accidentally absorbs water, its thermal insulation function must be guaranteed. 3, None of the organic material should applied to production of insulation materials, Thermal insulation material containing organic matter may get rotten, mildewed, and cause other destructive . At the same time they should not contain flammable substances, in order to avoid the fire. I hope my answer can help you
Q:What is acid refractory material?
Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry. Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment. High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
Q:What is the role of the vermiculite fireproof material?
Apart from inflaming retarding, the materials covered with vermiculite has a lot of advantages including anti rust, waterproof, anticorrosive, wear-resisting, heat-resisting and the coating is armed with toughness, colorability, adhesiveness, fast-drying and luster.
Q:How to divide fire resistant level of fire door?
Fire resistant level of fire door【Class A fire door】. Class A fire door is also called complete fire door. It can meet the requirement of fireproof thermal insulation and refractory integrity at the same time in specified time. Fire resistant levels are 0.5h(Grade C), 1.0h(Grade B), 1.5h(Grade A) and 2.0h, 3.0h. 【Class B fire door】Class B fire door is also called part heat insulation fireproof door. Its requirement of fireproof and thermal insulation performance is 0.5h. Refractory integrity levels are 1.0h, 1.5h, 2.0h and 3.0h respectively. 【Class C fire door】Class C fire door is also called not thermal insulation fireproof door. Ther is no requirement of its fire resistance and thermal insulation. It only meets the requirement of refractory integrity in specified refractory time. The grading of refractory integrity is 1.0h, 1.5h, 2.0h and 3.0h respectively. There is the content of not thermal insulation fire door in British BS standard.
Q:How many hours of the fire endurance time of the rock wool laminboard?
This is depending on the fire rating, about two hours and the better one, 5 hours.
Q:what's the varieties of fire-proof sealing material?
ATD-AB, organic fire-proof caulking, fire retardant bag, fire retardant net, fire retardant ring, fire barrier wrap, fireproofing sealing strip, flexibility fireproofing coiled material, fireproof glue, etc., fireproofing sealing materials currently on the market can be divided into two types, one is the traditional type: flexible organic caulking, WXY-II, fire retardant bag, fire bulkhead, cable refractory coating; there are some new materials used in large-scale projects: fireproofing coating board system (fireproofing coating board, intumescent fireproof sealing tape, elastic fireproof sealant, Waterborne Fire-retardant Coating), fire retardant module system (fire retardant module, sealing gum, cable refractory coating), fireproofing plaster system (fireproofing plaster, sealing gum, cable refractory coating).
Q:How do refractory materials apply into pyrophyllite?
When it is sized, add some clinker and after calcination, aggregate will be finished. From: turn to help
Q:What parts of cement kilns are refractories used on?
In kilns.
Q:what are the types of piping insulation material fire rating?
There are two grades: 1, the organic material: Grade B Grade B1 hard combustion (fire retardant) 2, inorganic materials: class A no burning it is divided into three levels, attributed to the types of materials!
