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...
Before kiln, the characteristic that should burn base glair according to place decides a graph that warm up and drops in temperature. Distributinging circumstance of the curve and following element are having close relationship: 1, the ply of the water content;3 when the composition of preform and purity;2, base substrate enters pit, base substrate and size, the type that the temperature of base substrate conducts coefficient;4, kiln, construction and capacity...
2004, with one action of crop of global crude steel breaks through 1 billion T to close greatly, among them crop of crude steel of electric steel factory is 1.5 billion T, worldwide inside the rate that electric steel place holds all is in 33% the left and right sides. Reckon global steel output will achieve 1.15 billion T 2005, among them blast furnace steel occupies 750 million T, electric steel occupies 365 million T. The main raw material of tradition of electric stove steel-making...
The has poriferous structure adiabatic and fireproof product that clay pledges heat preservation brick points to Al2O3 content 30%-46% . Basically use but the poriferous product that model pug lights ashes to add thing or slop bubble law or chemical legal system become. National level (GB3994, 1983) presses brick of argillaceous qualitative heat preservation bulk density cent to be NG-1.3, NG-1.3a, NG-1.3b, NG...
The knot broken bits of the itself of ash content is characteristic, this is main the compositive circumstance with all sorts of compound in grey bate temperature, ash (content of sulfur, iron is big, grey dissolve point is low) , the atmosphere with located coal ash (ash is in reducing atmosphere to be nodded than oxidisability atmosphere dissolve low) wait for an element to concern. The external cause of knot broken bits: 1, empty tolerance is not worth;2, fuel and air when combustion...
Although kiln blocks igneous board and fire-wall to be controlled to the operation of kiln furnace in path kiln,have a lot of positive effect, but if be mixed in the amount,install locally unreasonable, also can go up to control bring negative effect, reason puts forward a few principles to offer reference. 1, the action kiln that kiln path blocks igneous board and fire-wall on the road the effect that blocks igneous board and fire-wall place to rise is main...
Saddle steel took the lead in using much brilliant Mo Laishi in area of burner of complete hydrogen bell furnace fireproof fiber vacuum shapes compound brick. Although heat insulation and bulk density problem were solved in burner area. Its service life appears mostly after a year horniness piece clearance increases, craze falls off. Much brilliant Mo Laishi is fireproof fiber vacuum shapes compound brick is right complete hydrogen bell furnace...
Magnalium is qualitative fireproof and pouring the composition of makings and function magnalium are qualitative fireproof and pouring expecting is by frit of electric frit magnesia, agglomeration magnesia, report or agglomeration magnalium corundum of frit of pointed spar, report, alumina pink, tall aluminium powder make up and become. Bond has silicon of water glass, oxidation and alumina cement of small pink, aluminous acerbity calcium, phosphate. Magnalium is qualitative fireproof irrigate...
