Description
Technical field
The utility model belongs to Bottom of Heating Furnace water pipe adiabatic heat-insulation technical field, especially relates to a kind of heating furnace water beam wrapping ceramic fibre combined type wrapping layer.
Background technology
Heating furnace water beam within adding the hot stove of steel rolling is the vitals that supports the steel billet motion, its heating furnace water beam is comprised of Bottom of Heating Furnace water pipe and slide block, its Bottom of Heating Furnace water pipe 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 under hot environment, the water beam supports, logical circulating water in the water beam, for energy-conservation purpose, most adopts Vaporization Cooling.The thermal insulation protection effect to prevent that in the water beam, cooling water absorbs a large amount of heat 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: be welded with the anchor studs that increases adhesive strength on the water pipe of water beam, the water beam is with castable or moldable with cast or ramming mode, that water beam wrapping 60-70mm is thick respectively, material mainly consists of with powder and the sand of alundum (Al2O3), silica, bonding with curing materials take cement or aluminum phosphate as main, after wrapping through normal temperature cure again by operation work after certain parameter baker High-Temperature Strengthening.Above-mentioned material is made the prefabricated section of all size, form the higher wrapping of intensity watt after sintering, watt be embedded in the anchoring piece that contacts with the water pipe outer surface of water beam and coordinate, usually adopt welding manner will wrap up around watt water pipe that is fixed on fast the water beam, wrapping watt seam is filled sealing with clay, and speed of application is fast, need not baker.
the 2nd, compound wrapping: first be welded with the anchor studs that increases adhesive strength on the water pipe of water beam, be wound around again the certain thickness cellucotton of 20-30mm, at last with castable or moldable with cast or ramming mode, that water beam wrapping 60-70mm is thick respectively, material is mainly with alundum (Al2O3), the powder of silica and sand consist of, bonding with curing materials take cement or aluminum phosphate as main, after wrapping through spontaneous curing again by operation work after certain parameter baker High-Temperature Strengthening, due to effect of heat insulation material preferably being arranged in 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 water pipe, and refractory material is heavy (proportion is generally at 2.3-2.8), volume and weight are larger, due to build, ramming construction heat temperature resisting sliding lumps both sides, water pipe top can't accomplish real smooth slope, will cause like this alluvial of the iron scale of steel billet, form that the shielded area affect heating steel billet 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 affects the heating steel billet 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 larger, build, ramming construction heat temperature resisting sliding lumps 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, affecting heating steel billet quality steel billet, to form black seal more obvious, and steel billet time inside furnace and Fuel Consumption increase.
Tradition wrapping material therefor volume is large, weight is large, and construction intensity is large, and consumption of materials is large.Cast or ramming mode are constructed has certain requirement to normal temperature cure and the process of strengthening that heats up, and has increased certain furnace drying time.
Chinese patent ZL 200610039212.6 discloses a kind of employing polycrystalline mullite fibre and has been made into two wrapping layers, hang on anchor studs and stick on the method for on water pipe, the water beam being wrapped up by high-temp glue, can realize the heat insulation of water beam and protection, but because technology at that time only limits to polycrystalline mullite fibre is made cotton shape or soft bulk, intensity difference, resistance to erosion not, wrapping layer is inboard to be connected with the water beam owing in bonding process, high-temp glue being coated in addition, because high-temp glue can not permeate or be attached on metal pipe-wall and metal pipe-wall, high-temp glue, the expansion of polycrystalline mullite wrapping layer under different temperatures, difference in shrinkage is large, so described high-temp glue can't realize for a long time wrapping layer being fixed on water pipe, final polycrystalline mullite wrapping layer washes away gradually and peels off or directly separate and come off from anchor studs from water pipe.Therefore can not steady operation, more be not suitable for the long-term use at heating furnace water beam, cause it not apply.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and intensity is good, be not easy to come off, convenient construction, replacing, lightweight, and the heating furnace water beam wrapping of good heat-insulation effect is with ceramic fibre combined type wrapping layer and wrapping method thereof.
The purpose of this utility model is achieved through the following technical solutions:
