The service life of industrial kiln furnace basically is decide by the service life of fireproof material liner, liner is by fireproof and firebrick, pouring makings and brick of light qualitative heat preservation form. The build by laying bricks or stones of kiln furnace builds economic performance to affect the investment cost, character of service, thermal efficiency, the sources of energy that run to use up charge to wait directly. With heat-insulation layer of build by laying bricks or stones of brick of light qualitative heat preservation, can be outside regenerator of build by laying bricks or stones wall while build by laying bricks or stones is built, after also can baking kiln again build by laying bricks or stones, but should beforehand build by laying bricks or stones gives Latin brick, in order to make heat-insulation layer and outside the wall becomes one whole, prevent layer of heat preservation brick and wall body to come off, heat preservation brick and regenerator wall put oneself in another's position are taken commonly in construction at the same time build by laying bricks or stones is built. Ply of actual heat-insulation layer can be half, one, a half brick. The surface outside its also can add the heat-insulation layer; that makes other material calcareous plate of light qualitative silicon, it is to be in outside regenerator between wall pillar every other is certain the angle iron on high solder, one by one of will small qualitative siliceous calcareous plate inserts angle iron between, construction ply is one layer board thick (the construction of 50 siliceous aluminous beaverboard is more a few more troublesome, besides the solder angle iron that prop up, wear in net of reinforcing steel bar of freely direction solder even, ply is adjusted by the requirement. Only heat preservation coating chases layer daub construction on OK and outer wall, arrive at requirement ply continuously, normally hind 3 kinds of material are not direct contact with fireproof material, however construction at heat preservation brick outside. Because this chooses the characteristic of brick of light qualitative heat preservation,be (1) the function of kiln furnace and hot project characteristic. The kiln furnace that works like clearance sex should choose the material with small thermal capacity. (2) intensity of system of the safe use temperature of material, heat conduction, high temperature, chemical stability. (3) use life. (4) investment expenses upholds charge with what move. Build by laying bricks or stones is built with firebrick cent attachs most importance to qualitative firebrick and light qualitative firebrick (brick of light qualitative heat preservation) . Weighing qualitative firebrick to emphasize particularly on is high temperature stability, chemical stability what wait for; and pledge heat preservation brick is paid attention to gently is sex of heat preservation heat insolation and economy. Value of coefficient of thermal conductivity is little, the adiabatic result that shows insulation material is good, the fare of the sources of energy when moving is low. The fare of investment of charge low specification of insulation material of every unit volume is low, have good investment economy effect. 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 kind of meticulous project, each link should let achieve quality to ask to pay attention to essence of life strictly to be checked construction, frequently in construction process. Layer of heat preservation job supports to introduce relevant construction method with kiln wall and kiln below, in order to offer reference. (1) build by laying bricks or stones of heat preservation brick is built. The height of heat preservation wall, ply and overall length accord with the regulation of blueprint paper. Its build by laying bricks or stones builds method and clay qualitative firebrick is identical, use fireproof slop build by laying bricks or stones to build. System of build by laying bricks or stones should make sure grey full oar is solid, its plaster is full degree should achieve 95% above. Forbidden use hammer knocks a brick when bricklaying, the face that uses rubber hammer light clap to hit a brick looks for his. Forbidden the knife that use ash chops a brick directly, the cut of applied cut machine that needs treatment is orderly. To avoid heat preservation brick direct with bright fire is contacted inside kiln, of observation hole all around build by laying bricks or stones builds usable firebrick, heat preservation wall and heat preservation cotton and outside of the wall build receive a brick to also apply clay to pledge firebrick build by laying bricks or stones is built. (2) shop of heat preservation cotton is stuck. Heat preservation cotton board the requirement that dimension wants to accord with a design already, want to satisfy the real need of convenient installation again. The attention answers in installing a process: The contact is close together between cotton board, narrow as far as possible its connect clearance, be in place of cotton board connect, good with adhesion of high temperature binder, make its sealed tight, ensure effect of its heat preservation. The cotton that machines to need board, cut of applied cutting tool is orderly, forbidden with the hand direct tear at. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development, construction is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
