Features of Magnesia Brick

Magnesia Brick , it is to point to magnesium stone as raw materials, the Israeli magnesium stone as the main crystal phase, MGO style content in 80% ~ 85% or more of the refractory brick. Its products are divided into two categories: Metallurgical magnesia and magnesia products. Magnesia brick is the main products of basic brick, high refractoriness, of alkaline slag and iron slag has good resistance, high refractory brick is a kind of important. Mainly used in open hearth, oxygen converter, electric furnace and non-ferrous metal smelting, etc.

Typical Application of Magnesia Brick

Furnaces of metallurgy industry, heat treatment furnace.

Furnaces of chemical industry and construction industry.

Furnace of incineration of garbage, recirculating fluidized bed furnace .

Q:What are the specific raw materials for plastic pallets?: There are two kinds of raw materials for plastic pallets: one is polypropylene (PP) and the other is polyethylene (HDPE).Plastic pallets for logistics storage: pp+pe material, recycled material 10%;Plastic trays for food trays: food grade PP, PE, pc;Polyethylene (HDPE) has excellent impact resistance and cold resistance, and it can resist environmental stress cracking. Excellent chemical stability, good oil resistance. Water absorption and tiny, low permeability, organic vapor transmission rate is larger. Electrical insulation is good, in all frequency range, dielectric properties are extremely excellent.

Q:What is the difference between corundum and high alumina??: The main components of high alumina brick are high alumina bauxite, mullite and partial corundum sand.

Q:What's the price of high alumina refractory bricks?: The price of high alumina refractory bricks varies greatly according to the content of AL2O3.

Q:Which is faster for heat transfer between corundum bricks and high alumina bricks?: There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.

Q:How can the refractory brick blast furnace be pulverized and pulverized enough not to be taken away by the wind?: Because the hot air outlet of the top burning hot blast furnace is high, the installation requirement of the hot air manifold is high, and the requirement of the strength of the pillar structure is higher, so the rectangular arrangement of the hot blast stove is arranged. The top burning hot blast stove is located on the furnace top because of burner and hot air valve,Therefore, operation, maintenance and installation all require mechanization and automation. Also, because these water cooled valves are mounted with a high elevation,Therefore, the demand for cooling water supply pressure should be improved accordingly, the use of large top burning hot blast stove, the key lies in the design of high-power high-efficiency short flame burner. The top combustion hot blast furnace absorbs the advantages of internal combustion and external combustion hot blast stoves, and overcomes some of their shortcomings,Its structure can meet the requirements of modern blast furnace for high temperature, high pressure and large scale development,Combustion capacity, while meeting production requirements, has been successfully reduced by many devices,

Q:What is the price of the first grade high alumina brick?: The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories

Q:What are the requirements for Rubble backfill height?: 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.

Q:Use of high alumina refractory bricks?: Because of the high Al2O3 high aluminum products, low impurity content, the formation of fusible vitreous body less so than the clay brick high load softening temperature, but because mullite crystallization has not formed the network organization, so the load softening temperature is not high silica brick.

Q:What materials are used for roof insulation?: The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.

Q:What is the difference between fireclay bricks and high alumina refractory bricks?: First of all, there is a difference in the material, one is clay, and one is high aluminum.Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.
