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.
Silicon line stone is a kind natural and advanced fireproof and mineral, it has heat to expand rate is low, fight metallurgy slaggy with all sorts of glass fluid erode, high temperature wearability is good wait for a characteristic. Its manage turning performance is better than tall aluminous brick, fireproof 1830 ℃ of degree of 1770 ～ , loading bate begins 1650 ℃ of bit of 1500 ～ . Utility of silicon line stone 1 high temperature resistant prevent wear paint; 2 silicon line...
Zirconium not comes stone brick is the founding that is raw material with Molaishi and zirconia refractory products. Structure of crystal of brick of founding of zirconium Mo Laishi is compact, loading bate temperature is high, thermal stability is good, mechanical intensity is high below normal temperature and high temperature, wearability is good, thermal conductivity is good, and have the capacity that admirable resistance erodes. Agglomeration zirconium not comes stone brick is to employ worker worker...
Compound Molaishi the brick is two layer or multilayer material is qualitative compound produce and become, have the effect such as heat preservation of wear-resisting heat insolation. Firebrick is comprised by working layer, thermal insulation, use synchronism to shape, synchronous combustion technology. Working layer uses electric frit Mo Laishi, leveling aluminous grog, high grade andalusite, additive, alkali resistance erodes ability strong, be able to bear or endure tall...
According to fireproof material different, steel wraps the construction method of liner to also differ, be like the choice of firebrick, construction method is body of build by laying bricks or stones, irrigate the alternative that builds material to build construction to irrigate, have by the bag breathe freely brick, also have without breathe freely brick, still work is changed breathe freely the brick. Include the discussion of liner craft and test through of all kinds to the steelworks steel, liner is departmental...
Tall aluminous brick calls light qualitative heat preservation tall aluminous adiabatic brick again. Among them alumina content is in the 48% above, light qualitative fireproof material that basically constitutes jointly by Molaishi and corundum. Bulk density is about between 0.4 ～ 1.35g/cm3. Apparent pore rate is in about 66% ～ 73% between, compression intensity 1 ～ 8MPa. Have good heatproof shake performance. Light...
The choice of brick of adiabatic and fireproof heat preservation and specific requirement are concerned, if coefficient of thermal conductivity, temperature, density, material is qualitative,content is waited a moment. Density of the material composition of brick of light qualitative adiabatic heat preservation and structure, porosity and stomatic feature, bulk, temperature is main factor. Brick of fireproof and adiabatic heat preservation main effect is heat preservation heat insolation, reduce heat energy prediction of a person's luck in a given year, ...
Does fireproof material have torpedo pot what characteristic? Regard metallurgy as the important segment of the industry, fireproof material must have pot of torpedo of molten iron pretreatment sex of shake of good acid-proof sex broken bits and basic slag aggressivity, heat-resisting and be able to bear or endure flake quality. Generally speaking, not the torpedo canister of desulphurization is used firing argillaceous brick or andalusite brick, liner uses argillaceous brick commonly...
Compound firebrick is combined by small qualitative part and heavy qualitative part and become, manufacturing technology is trivaller, apply in furnace of high temperature kiln extensive. Compound firebrick is two layer or multilayer material is qualitative compound produce and become, have the effect such as heat preservation of wear-resisting heat insolation. Compound firebrick is comprised by working layer, thermal insulation, use synchronism to shape, synchronous combustion is versed in...
Method of construction of brick of light qualitative heat preservation pledges the build by laying bricks or stones of heat preservation brick is built gently is a detailed engineering. In construction process, to satisfy the quality requirement of each link, must notice careful construction strictly, often check. It is the relevant construction method of kiln wall and kiln top heat-insulation layer below, offer reference. (1) build by laying bricks or stones of heat preservation brick is built. The height of heat preservation wall...
Brick of heat preservation of light qualitative clay belongs to insulation material, it is the small qualitative adiabatic products in fireproof material, commonly used at kiln furnace heat-insulation layer. Brick of light qualitative clay can be used burn break a law, reduce firebrick density. Often use have curium wooden layer, charcoal, coal fines and other organic matter. Bleb law, the stoma in goods is to use bubble legal system to become...
RH furnace follows the development of fine craft to update progress ceaselessly with fireproof material, be able to bear or endure character from inchoate tall aluminium material, it is newlier common and firing magnesian chromium is able to bear or endure character material, hand-in-hand pace is direct union magnesian chromic brick, half recombine or recombine magnesium chromic brick. Tervalent chromium issues can progressively change to be 6 price chromium in certain condition in magnesian chromic brick, pollute an environment badly, minatory person...
Because have technique,refine copper plant uses converter simple, operate easy, efficiency advanced characteristic, be grown by refine copper plant consequently period in the blowing process that uses extensively at cupreous milometer. The blowing system of blowing system converter has 3 kinds: Odd furnace blowing, furnace exchange blowing and period commutative blowing. Current, home uses furnace of only station blowing to exchange blowing more. ...
