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...
In aluminous aluminous grog, common impurity has TiO2, Fe2O3, K2O, CaO to wait, the effect that its produce to aluminous alumina is as follows: 1, TiO2 is the impurity with the higher content in aluminous alumina. In 2 class aluminous alumina, tiO2 basically fashions solid solution with Molaishi, enter vitreous phase little, aluminous to aluminium agglomeration is adverse, but can raise its...
Furnace of LF steel bag is to use electric arc to heat fine equipment of the technology, it is the molten steel park in the Chu Lian in general steel-making furnace special steel bag has refined facility. The characteristic of LF furnace is undertake by 3 electrode; heats through electrode on one hand burying arc to heat build; of tall alkalinity reducing slag to undertake composition of deoxidization, to decoke, molten steel is adjusted on the other hand etc...
In recent years, compound and fireproof material already made the metal the heat of research, in if wait for Si, Al and Fe,introducing fireproof material, research developed carbon of cup of Si-Si3N4- corundum qualitative pottery and porcelain, Al- - corundum qualitative slide and Fe-AlN-MgO-Si3N4 composite material, some already aborning received promotion application, the effect that gained satisfaction...
The dust inside furnace compares coal fired annealing furnace big, use the means that mechanical coal fired heats secondhand, can reduce furnace inside of big grain dust invade, law of this kind of combustion is to belong to aerification of half dirty coal to burn. The dust immerge of coal fired arrives fireproof fiber surface, without intense chemical reaction, the combustion of coal and formation atmosphere, cannot make right...
The working requirement of each place lining should understand converter magnesian carbon brick is on converter the application of each place, above all, need to understand converter the working environment of each place. It is the reason that the eroding that each place gets easily mars below. 1. Change of the mouth feed a machine, blowing, tapping, temperature when pouring broken bits is big, slag is eroded, of the waste gas that carry this world is brushed, feed a machine...
