Description
Technical field
The invention belongs to heating furnace floor tube adiabatic heat-insulation technical field, especially relate to a kind of wrapping of heating furnace water beam ceramic fibre combined type wrapping layer and wrapping method thereof.
Background technology
Heating furnace water beam in adding the hot stove of steel rolling is the vitals that supports the steel billet motion, its heating furnace water beam is made up of heating furnace floor tube and slide block, its heating furnace floor tube is divided into single water pipe structure and two water pipe structure, the slide block (also claiming cushion block) of top assembling.Be the structural strength that guarantees that the water beam supports under the hot environment, logical recirculated water cooling in the water beam, for energy-conservation purpose, great majority adopt the vaporization cooling technology at present.The thermal insulation protection effect to prevent that cooling water absorbs a large amount of heat in the water beam in stove, is played to water beam and slide block piece by the refractory material wrapping of various insulations simultaneously in water beam outside, prevents at high temperature scaling loss and oxidation.
Tradition wrapping mode has following two kinds:
The one, individual layer wrapping: on the water pipe of water beam, be welded with the anchor studs that increases adhesive strength, the water beam is with watering material feeding or moldable with cast or ramming mode that water beam wrapping 60-70mm is thick respectively, material mainly constitutes with the powder and the sand of alundum (Al, silica, bonding and curing materials be based on cement or aluminum phosphate, after the wrapping through normal temperature cure again by operation work after the certain parameter baker High-Temperature Strengthening.Above-mentioned material is made the prefabricated section of all size, behind sintering, form the higher wrapping of intensity watt, watt be embedded in the anchoring piece that contacts and cooperate with the water pipe outer surface of water beam, usually adopt welding manner will wrap up around watt water pipe that is fixed on the water beam fast, wrapping watt seam is filled sealing with clay, and speed of application is fast, need not baker.
The 2nd, compound wrapping: be welded with the anchor studs that increases adhesive strength on the water pipe of water beam earlier, twine the certain thickness cellucotton of 20-30mm again, at last with watering material feeding or moldable with cast or ramming mode that water beam wrapping 60-70mm is thick respectively, material is mainly with alundum (Al, the powder of silica and sand constitute, bonding and curing materials are based on cement or aluminum phosphate, after the wrapping through spontaneous curing again by operation work after the certain parameter baker High-Temperature Strengthening, owing to effect of heat insulation material is preferably arranged in the compound wrapping, in the water beam cooling water take away heat in the stove can be to reducing.
The shortcoming of above-mentioned two kinds of wrapping modes is:
The gross thickness of individual layer wrapping is 60-70mm, the wrapping effect of heat insulation is poor, a large amount of heat energy is taken away by the cooling water in the water pipe, and refractory material is heavy (proportion is generally at 2.3-2.8), volume and weight are bigger, because build, ramming construction heat-resisting slide block both sides, water pipe top can't accomplish real smooth slope, will cause the alluvial of the iron scale of steel billet like this, form that the shielded area influence steel billet heating quality, black seal is obvious;
When adopting wrapping watt wrapping; still can form more wide heating at one section working time rear oxidation iron sheet covers and influences the steel billet heating quality; and engage between wrapping layer and meet that to become the pad intensity of weak spot wrapping watt relatively poor again for vertical masonry joint; flame or furnace gas meet the anchoring piece and the phase of solder joint that are embedded in piece to contact through engaging; being easy to oxidization burning loss causes wrapping layer to come off; wrapping watt is washed away by high-temperature furnace gas and vibrate to be easier to break, scaling loss, to come off, and the water beam loses wrapping protection.
Compound wrapping gross thickness is 70-80mm, its wrapper material volume is bigger, build, ramming construction heat-resisting slide block both sides, water pipe top can't accomplish real smooth bevel, will cause the alluvial of the iron scale of steel billet like this, formation is covered, influencing steel billet heating quality steel billet, to form black seal more obvious, and steel billet time inside furnace and Fuel Consumption increase.
