Specifications
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'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: What are the qualifications of refractory industry?
- Special qualification issued by Fire department
- Q: Refractory materials are needed for casting metallurgy.
- High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.
- Q: Why does refractory need to add coarse firstly and then add fine aggregate?
- Adding coarse aggregate is to assure its good combination with fine aggregate. This is just the experience. You don't have to ask.
- Q: How many refractory materials does the annual output of 1 million tons of coke oven require?
- Refractory material is an important material used in iron and steel industry, it is mainly used in steel-making furnace, furnace lining, loading and transportation of metal and slag ladle lining, the furnace lining procedure of billet heating, heat conduction and lining of blast furnace and the flue. So, to put it simply, we can think of it as a structural material, which can withstand a temperature of 260-1760 degrees centigrade.
- Q: How to classify the grade of wall fireproof and thermal inuslation matertial?
- External wall thermal insulation materials are mainly divided into grade A, grade B1, grade B2 and grade B3. In accordance with the current "Combustion Performance Classification Method of Building Materials", grade A thermal insulation material is incombustible?material and belongs to inorganic heat preservation material. However, grade A thermal insulation material is few in terms of the current market. There are only JETCO YT inorganic active wall thermal insulation material, glass wool, rock wool board, foam glass, vitrified micro bead and grade A fireproofing thermal insulation board. However, compared with grade A thermal insulation material, the more welcomed by the market is the organic insulation materials. Thermal insulation material that is determined as grade B is divided into three levels. Grade B1 is grade is flame retardant. Grade B2 is combustible. Grade B3 is flammable.
- Q: What effect does aluminium powder play in refractory bricks?
- Aluminum powder can increase the high melting point of refractory refractory, while increasing material density, hardness and other changes in physical properties of aluminum powder in the application of unshaped refractories in the gas can be discharged in the material, prevent the refractory sudden warming occurred during the burst.
- Q: How to make use of waste refractory materials whose main elements are alumina and mullite?
- Crushing and pressing refractory bricks, or refractory parts . Such as welding positioner tracks use disposable tools.
- Q: What are the technical requirements for refractories?
- How high the temperature is and what is this refractory?
- Q: Pals who know something about fire resistant material please tell me how many types of refractory material there are
- There are a variety of refractory materials, each of different use. It is necessary to make resonable classification for refractory materials so as to facilitate scientific research, rational selection and management. There are many kinds of classification methods for refractory materials, including classification based on chemical property, chemical mineral composition, production process, material form and other methods. 1, according to the capacity of fire resistance: ordinary refractory materials: 1580 degrees C ~1770 C Advanced Refractory Materials: 1770 degrees ~2000 degrees c: Classification according to product shape and size: standard 230mm×113mm×65mm no more than 4 scales
