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.
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...
One, acid-proof brick sticks a shop to should press following program to undertake graph of technological process of acid-proof brick construction sticks a shop partly note of acid-proof ceramic tile: When having ceramic tile of line build by laying bricks or stones, bricky board must the fault is seamed arrange, the brick that be the same as a layer is seamed should stagger the 1/3~1/2; of bricky board width is adopted knead brick of crowded law line, ash is seamed should full and close-grained, ash seams the surface to press smooth; to establish face brick at any time successive...
What the particular construction kind of fireproof material liner narrates incinerator as follows. 1. Specific construction (1) undertakes checking metrical to incinerator, look pull bricky board in good condition, set stock to not have be out of shape, furnace each place dimension whether with design standard conform to, whether does whole furnace accord with build by laying bricks or stones to build a demand. (When 2) furnace accords with build by laying bricks or stones to build a demand, clear furnace wall dry...
Want to master the function of all sorts of fireproof material, especially high temperature performance characteristics, because they can be right,attaint element has counteractive effect directly, specific saying is fireproof degree, stability of bulk of intensity of high temperature structure, high temperature, thermal shock stability and chemical stability. For example in the performance characteristics of brick of common agglomeration tall aluminium, its are main the advantage is...
Heat treatment furnace is as follows to the requirement of burner: (Side of 1) adjustment performance, heat treatment craft stipulates workpiece heats have longer thermal insulation period, the thermic load of heat preservation period is less than far warm up period, differ to arrive severalfold ten times, when the bear of such bigger change, ask burner also can be used normally, criterion burner should have bigger adjustment to compare, right...
Reduce steel to include fireproof bill of material bad news is resource of managing to steely enterprise fireproof material, energy-saving a when decrease a platoon main effect, to achieve this one goal, some steelworks uses new design on 60tLF steel bag and the condition is operated on the lid, got remarkable result. 1, the operation requirement that includes according to steel designs magnesian carbon brick this steel bag is eroded fast...
