New-style and fireproof material is in the action of iron and steel industry

March 15, 2024Nov 25, 2024
New-style and fireproof material is producing mainer and mainer effect in iron and steel industry, efficiency of help promotion production, reduce specific power consumption, lengthen service life of equipment, satisfy the environmental protection requirement that raises ceaselessly. It is new-style and fireproof material below the main effect in iron and steel industry and applied domain:


1.Improve manufacturing efficiency
The high-powered fireproof data such as the applied magnesium chromic brick of 1.1 high-powered fireproof data, magnesian carbon brick is in the critical process equipment such as converter, electric stove, Lian Zhu wide application. These material are had exceedingly good high temperature resistant gender and fight chemical aggressivity, can bear the high temperature in steely production process and harsh environment, what assure to produce a course thereby is successional with stability.  1.2 take its natural course are peaceful fireproof and pouring makings take its natural course is peaceful fireproof and pouring makings have good liquidity and uniformity, can form in the equipment liner of complex form compact, without seamed fireproof layer, reduce cold repair time, improve the moving efficiency of equipment.
2.Lengthen service life of equipment
2.1 high temperature fight those who because its are exceedingly good,eat the new-style and fireproof stuff such as brick of brick of material pointed spar, aluminium magnesium carbon to fight aggressivity and heatproof shake sex, in bag of converter, electric stove, steel, Lian Zhu the crucial position of the equipment such as the bag intermediate gets applied extensively. These material can resist effectively molten steel, slaggy with high temperature gas erode, prolong the service life of equipment, decrease maintain frequency and cost.
Makings of base material of carborundum of 2.2 wear-resisting material, zirconium pledges the new-style material such as fireproof material has very tall wearability, apply to get acuteness tatty place, be like chute, duct path and hearth, prolong the service life of these components significantly.
3.Reduce specific power consumption
Small hole of 3.1 efficient insulation material the new-style heat preservation such as thermal insulation board of rice of heat insulating materials, accept is fireproof material exceeds low coefficient of thermal conductivity because of its, can reduce loss of quantity of heat effectively, improve the thermal efficiency of steely production, reduce specific power consumption. These material apply extensively at the heat-insulation layer of high temperature body of heater, and the heat preservation liner that Bao Hegang wraps among Lian Zhu.
3.2 energy-saving model the new-style material such as firebrick of light qualitative firebrick, low thermal conductance is reducing firebrick kiln furnace heats up losing at the same time, those who keep taller is fireproof spend and intensity, apply to the liner of all sorts of high temperature body of heater, behave in high temperature area especially good.
4.Promote a product quality
Production of 4.1 clean steel exceeds low carbon fireproof material (if exceed brick of low carbon magnesian carbon) the carbon in can reducing fireproof material enters steel fluid, those who assure molten steel is clean degree, apply to the clean steel that produces high quality. Without carbon fireproof material is like brick of pointed spar of the aluminium magnesium that do not have carbon, apply to production to ask tall steel is planted, can prevent the separate out of carbide, what promote molten steel further is pure degree.
4.2 fight oxidation material to fight magnesian carbon brick, aluminous carborundum to pledge fireproof material is had in high temperature environment fight oxidation function goodly, the service life of equipment can be prolonged below the premise that does not affect molten steel class status, apply to high to requirement of molten steel quality technology.
5.Satisfy environmental protection requirement
5.1 without chromic fireproof material as environmental protection code increasingly strict, the tradition contains chromic fireproof material to be not had gradually place of chromic fireproof stuff is replaced. The material do not have chromium such as brick of magnesian iron pointed spar, aluminium magnesium brick is had not only exceedingly good high temperature resistant and fight aggressivity can, in still can reducing manufacturing process of harmful material discharge, accord with environmental protection requirement.
5.2 low arrange data new-style low discharge fireproof material to be like brick of low carbon magnesian carbon, through optimizing the recipe of carbolic content and antioxidant, decreased to be in what high temperature issues the carbon monoxide of generation and hydrocarbon to discharge, conduce to the air pollution in reducing iron and steel to produce a course.
6.Answer mixed operating mode
Environment of high pressure of 6.1 high temperature is aimed at environment of high temperature high pressure, like blast furnace liner, new-style char composite material and carborundum nitrogen change silicon radical silicon union material can be offerred the good compression, corrode that fight broken bits and fight oxidation function, the long-term stability that ensures equipment falls in abominable condition moves.
6.2 be able to bear or endure the data with strong stability of urgent cold urgent hot thermal shock, be like brick of pointed spar of zirconium stone brick, aluminium magnesium, apply to the environment with fluctuant and acuteness temperature, if steel wraps broken bits line to wait, because urgent cold urgent tropics comes,can resist effectively damage, prolong liner life.
7.Future develops way
As the progress of science and technology, fireproof material will forward intelligence is changed, compound change and environmental protection way develops. For example, fireproof material can realize intelligence online monitor and from repair, enhance the manufacturing efficiency of iron and steel industry and security further. The advantage that composite material passes a variety of data is complementary, satisfy more complex operating mode requirement. Environmental protection fireproof material will be in ensure high-powered while, reduce the effect to the environment, develop to can last of iron and steel industry make contribution.
As a whole, new-style and fireproof material promoted production efficiency and product quality not only in the application in iron and steel industry, still reduced specific power consumption and environmental effect, the modernization that is iron and steel industry and green changed development to provide strong support.
