  • Characteristic of brick of tall aluminium of light qualitative heat preservation reachs useless brick utility

    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...

  • How does brick of adiabatic and fireproof heat preservation choose?

    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, ...

  • Torpedo canister repairs the introduction with firebrick and liner

    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...

  • The characteristic of compound firebrick

    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 and impact pledge factor of adiabatic brick property introduces gently

    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 introduces

    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...

  • Why should be RH furnace changed without chromium with fireproof material?

    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...

  • Converter of refine copper plant uses fireproof material and operation method introduction

    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. ...

  • Refine lead uses Ao Simai special furnace and fireproof material introduction

    Ao Simai is special law fusion technology is applied extensively in all sorts of metallic extraction processes, can mineral products of fusion copper energy goes mine of lead of essence of vulcanization of cupreous milometer, direct fusion to produce concentrate of stannum of wide lead, fusion to produce tin, all sorts of broken bits material that also can handle smeltery and reworked material. Ao Simai is special the law is the fuse-element inside bath, charging, between gas...

  • Argillaceous brick produces the method that promotes finished product

    Argillaceous brick can bring about finished product percent of pass because of a variety of elements when production too low, pass related side law to be able to promote, detailed introduction looks please below. Argillaceous brick makes obsolete matter: Argillaceous brick dimension is unqualified, because mould installation is not firm, pattern plate is mobile; If enter,expect quantity wave motion is bigger, the change that also can cause blank dimension...

  • Brick of fireproof heat preservation: Do the choice of insulation material and construction introduce furnace of high temperature kiln?

    Begin lecturing of technology of brick of TOP fireproof heat preservation, is what share to everybody today about furnace of high temperature kiln how to choose insulation material? The main function of kiln basically depends on the technical economic performance of fireproof material, affect the investment cost of kiln directly. Character of service. Thermal efficiency. Cost of moving specific power consumption. Those who choose fireproof insulation material is general former...

  • How is brick of light qualitative clay produced?

    Furnace of kiln of TOP fireproof material applies technical channel begin lecturing, what share to everybody today is the knowledge that passes brick of light qualitative clay. Brick of light qualitative clay is the small qualitative refractory products of AL2O3 content 30%-46% , belong to firebrick of adiabatic heat preservation. Use clay grog or pledge argillaceous grog is mixed gently but model clay is main raw material, use combustible law to produce...
