Avoid the significant step that firebrick injures

Be damaged in use process to prevent firebrick, it is a few significant step below:
1.The firebrick stuff with right choice 1.1. High temperature resistant requirement: According to the upper limit of kiln furnace or anxious furnace working temperature chooses the material of firebrick. Measure: The choice can be able to bear or endure for a long time suffer high temperature and not bate or fused material, wait like silica brick of tall aluminous brick, magnesia brick, carbonization. 1.2. Heat-resisting shake asks: Material needs to have better heatproof shake sex, with the rapid change of counteractive temperature. Measure: The choice fights the stuff with thermal shock good performance, wait like tall aluminous brick, clay brick, zirconium brick. 1.3. Anti-corrosive requirement: According to the chemical environment inside kiln furnace (acidity, alkalescent or neuter) choose firebrick. Measure: The choice is able to bear or endure the stuff that chemistry eats, brick of the chromium that be like magnesium, carbon brick, zirconium qualitative brick. 1.4. Wear-resisting caustic asks: Firebrick should have good wear-resisting caustic performance, with counteractive mechanical wear. Measure: Choose the firebrick material of high density, high strenth, wait like carborundum brick, alumina brick. 2. Accurate construction method 2.1. Build by laying bricks or stones builds technical demand: Degrees the peace of close together sex that ensures firebrick build by laying bricks or stones is built is whole. Measure: Use appropriate brick to seam width, it is 1-2 millimeter normally. Use " dry build by laying bricks or stones " method, seam the osculatory pressure of place in order to reduce a brick. Puddle of use high temperature or fireproof slop undertake the brick seams fill, prevent a brick to seam become loose. 2.2. Expand suitably seam a requirement: The setting expands reasonably seam, the stress that because heat up,avoid to expand and arises brings about bricky body craze. Measure: Expand according to the set of hot coefficient of expansion of bricky material seam width. Use high temperature resistant flexible stuff stuff expands seam, like paper of fiber of pottery and porcelain, expand seam filling to wait. 2.3. Correct installation asks orderly: Follow reasonable installation order, cause loss in order to prevent follow-up operation to already installing firebrick. Measure: Chase an installation orderly according to the design, ensure to undertake dismantling installation again after every stability. 3. Reasonable operation is safeguarded 3.1. Control warms up and drop in temperature speed requirement: Avoid the rapid change of temperature, in order to reduce thermal shock loss. Measure: Litre of gentle rate of build-down of air temperature that controls kiln furnace or Jiao Lu, do not exceed 50-100 ° C hourly normally. Adjust temperature stage by stage when stop furnace or opening furnace, avoid suddenly cold heat up suddenly. 3.2. Examine a requirement regularly: Check the status of firebrick regularly, part of seasonable rehabilitate attaint. Measure: Make regular examination plan, those who examine bricky system wear away, break and corrode a circumstance. Use nondestructive detects method, be like infra-red detect or ultrasonic detects. 3.3. Control fuel and operation condition demand: Control fuel sort and use quantity, avoid excessive corrode and wear away. Measure: Use proper fuel, avoid fuel of tall sulfur, high ash content. Control the operation condition of kiln furnace, avoid what exorbitant wind speed or too old stuff shed pair of firebrick to erode. 4. Optimize design and structure 4.1. Optimize the structural demand of firebrick: The structure that optimizes firebrick according to the particular case of kiln furnace or Jiao Lu is designed. Measure: The brick with logical choice build kind with build by laying bricks or stones, in order to raise the stability of bricky body and durable sex. Use modular design, change and safeguard of convenient firebrick. 4.2. Prestressing force structure asks: In area of a few tall stress, the consideration uses prestressing force structure. Measure: Use reinforcing steel bar or other strengthen material, increase the integral strength of body of firebrick build by laying bricks or stones. 5. Use defend coating 5.1. Refuse demand of broken bits coating: In high temperature, slaggy contact area uses the coating that fight broken bits. Measure: Besmear Fu is high temperature resistant, fight cankerous coating material, be like aluminium magnesium coating or carborundum coating. 5.2. Adiabatic coating asks: Adiabatic coating is used in the area that needs heat preservation heat insolation. Measure: Besmear Fu is efficient heat-insulating material, reduce hot loss. Sum up the injury to prevent firebrick effectively, method of the alternative that needs to consider firebrick data integratedly, construction, operation is safeguarded, design construction and use defend the element of the many sided such as coating. Pass systematic precautionary measures, can improve the service life of firebrick, those who assure kiln furnace or anxious furnace is efficient move, decrease maintain cost.
