Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
Insulation material of class A fire prevention is medium the fire prevention insulation material that fire prevention grade is class A, its basically have A1 class and A2 class stuff, class A has density to do not burn material small, thermal conductance is low, bear control capacity taller, construction convenient, economy is durable wait for a characteristic, use as extensively on facilities of pipeline of hot conduit, industry of hot equipment etc and industrial structure...
Blast furnace is the main facility of puddling, it has yield big, productivity is mixed high the good point with low cost. Process of blast furnace smelt is including complex physico-chemical change. After puddling raw material is joined from blast furnace roof, those who pass oxide of warm-up, iron is reductive the combustion that issues trickle to move detached, coke with fused, iron and broken bits and generation are gas had waited...
Converter is the main smelt container of steel-making, its furnace life is affecting the manufacturing organization of steel-making directly, because this converter furnace life is,measure economic norms of a of converter steel-making omnibus technology. From 1991 American LTV steely company is used splash broken bits to protect furnace technology, since our country used this technology 1995, converter steel-making production produced those who pledge to fly...
Cliff sliver is a kind of insulation material, be in normally petro-chemical, application of power industry equipment is very wide, the use of cliff sliver is very extensive also, have adiabatic effect not only, still have fall the action of sound absorption of a confusion of voices, the adiabatic heat preservation that can build wall of partition, act, housetop and palisade is sound-absorbing fall a confusion of voices, still use at industrial kiln furnace, oven, big mouth...
Can synthesize with stone of alumina of industry of cyanite concentrate treatment, zirconium get grog of high grade zirconium Mo Laishi: Content is not less than Mo Laishi 93% , inclined zircon is not less than 5%; bulk density to not be less than 2.96g/cm3, apparent pore rate is more than 0.8% . Crucial question is to had controlled all sorts of craft parameter, be like: Al2O3 content, a/S comparing, zirconium stone...
In steel-making production on the rails, written guarantee Leng Gang's circumstance happens from time to tome inside steel bag. May accentuate when line of fine in use thermal conductivity build by laying bricks or stones of tall aluminous brick this kind of phenomenon, the meeting inside bag of together with steel drops because of molten steel temperature, still can bring liner surface to stick the problem with serious broken bits. Xi Zhengming had determined steel wraps tall aluminous liner, the molten steel heat inside 2h...
Limekiln of alleged and modern new technology has the modern limekiln with higher rate of environmental protection, energy-saving function and mechanization, automation namely. Because it used modern technology, so it can make full use of cheap the sources of energy, can use the gas that has pollution to the environment so to make main the sources of energy particularly, become useless to be treasure. Of limekiln of modern new technology...
The our country research to expensive chromic fireproof stuff, improve main body to show in the following respects: (Of 1) raw material optimize. In the tall chromic brick of first entrance, cr2O3 raw material basically is agglomeration Cr2O3. Raw material of Cr2O3 of opposite Yu Dianrong (opposite density is 95.2%) and character, the opposite density of agglomeration Cr2O3 (91.2%) is lesser, what produce product...
Thermal conductance is to point to inside unit time, below unit temperature gradient, the quantity of heat that place of unit area sample passes. According to Henan fireproof material factory introduces the thermal conductance of fireproof material to be versed in to high temperature heat the design of equipment is indispensable important data. Good to those requirement heat proof quality light simple fireproof stuff and function of requirement heat conduction...
According to frit kiln the development course of insulation material, can divide the traditional insulation material that already developed for early and the new-style frit kiln that in recent years research and development comes out insulation material. Insulation material basically includes traditional frit cave dwelling: Brick of light qualitative clay, siliceous aluminous beaverboard, small qualitative siliceous calcareous plate, light qualitative silica brick, high temperature resistant the new-style accept Mi Rong such as coating...
Design of the choice of fireproof material, body of heater and build by laying bricks or stones build each aspects such as the technology is to help us optimize the important step of lining of argon oxygen furnace. The experience that inchoate applying already made clear argon oxygen furnace: The mechanical wear that every area gets mixes lining of argon oxygen furnace eroding is each are not identical. In general, its are fireproof what liner gets is main wear away and...
Because the spot treatment of brick of corundum of electric frit zirconium is more difficult, the treatment precision of domestic product also is put in the inadequacy with particular move, it is improper that we think to use the wrong step that seam a platoon, reason converted the method of annulus build by laying bricks or stones. Use on the operation in manufacturer of electric frit brick the home undertakes be discharginged beforehand directly, further precision work, in ensure the dimension of each brick is contented should...
