Description
Technical field
The present invention relates to copper-alloy pipe-material production equipment field, be specifically related to a kind of horizontal continuous casting of copper gas shield crystallizer.
Background technology
Copper pipe and copper alloy tube are the critical materials of the heat-exchange system in desalinization, thermoelectricity nuclear power and naval vessel.Production of copper compo pipe at present, main method is extrusion, adopts alternate manner to bore a hole as oblique casting, and continuous casting rolls and draws seldom, extrusion process production process is: first batching casting circle base, through sawing, sorting, heating, extruding, pickling, then through rolling, be stretched to production tube, its defect is: (1) production process is numerous and diverse, and auxiliary equipment is many, maintenance die expense is high, floor space is large, and personnel require many, and competency profiling is high; (2) scale of investment is large, more than one hundred million units at least, several hundred million yuan at most; (3) justify base post bake, need extrusion modling, recipient, pin, need the energy consumptions such as preheating high before work; (4) the operation metal losses such as stirring, ingot casting, sawing, heating, pressure are remaining, decortication, pickling are large, and yield rate is low, for base yield rate <90%; (5) adopt single-unit furnace semi-continuous casting or the founding of split stove, continuous production is poor, and efficiency is low; (6) zinc scaling loss is large, stir, and post bake, extruding and the smog such as lubricated are large, seriously polluted; (7) pipe is eccentric large, affects follow-up cold working, and especially the extrusion yield of the large-caliber thin-walled brass tube of forward extrusion is 40%～60%.Generally speaking the technique of China's copper base copper alloy tube falls behind at present, and the quality of product is stable not, yield rate is low and cost is high.Horizontal casting is a kind of method of continuous casting, its principle is to utilize the principle of molten metal crystallisation by cooling, from the metal of melting or alloy molten solution, slowly extract continuously the effigurate solid metallic wire rod of tool or sheet material out, its advantage is that production capacity is large continuously without courses of work such as process extruding, rolling, drawings; Crystallisation by cooling system is a key equipment of horizontal casting, in cooling procedure molten metal be heated inhomogeneous, near a side cooling velocity of water jacket fast and away from a cooling velocity slow, cause pipe appearance to have crackle, solidified inside to organize thick defect.In condenser pipe market, HSn70-1 and Ha177-2 brass tube, BFe10-1-1 and the application of Bfe30-1-1 White Copper Tubes are many, if wherein HSn70-1 and Ha177-2 brass tube adopt horizontal casting, along with the solidification shrinkage of metal, liquid metals on graphite mo(u)ld by only depending on graphite wall to shrinking certain gap, there is alloying component in brass also to contain more zinc, and the fusing point of zinc is lower, the intra-zone solidifying at liquation divides zinc to volatilize to condense on crystallizer graphite mo(u)ld, extraneous air easily penetrates into gap from the port of export of pipe, and first metallic zinc of solidifying reacts with graphite mo(u)ld, thereby generating oxide sticks in graphite wall, increase the frictional force of pipe pull-out, and affect heat-transfer effect, greatly shorten the service life of graphite template, and along with production is carried out, the oxide of adhesion is more and more, in the time of pipe cast, easily makes pipe occur crackle with frozen metal while contact, inner or surperficial if oxide shedding is embedded in pipe, can destroy the ductility of matrix.
Summary of the invention
Object of the present invention is exactly the defect existing for prior art, and the horizontal continuous casting of copper gas shield crystallizer of the good and long service life of a kind of crystallization effect is provided.
The concrete technical scheme of the present invention is: comprise outside graphite overcoat and inner graphite centre rod, and graphite overcoat and graphite centre rod form annular inner chamber; The bottom of graphite overcoat is provided with inlet, and graphite overcoat middle part is up set with pressing plate, flange and cooling copper sheathing successively; Between described pressing plate and graphite overcoat, be provided with the refractory material protective sleeve that 15-20mm is thick; Described pressing plate inner side is provided with cooling jacket, is provided with electromagnetism generation cavity in cooling jacket, and multiple solenoids are installed in electromagnetism generation cavity, and solenoid is connected with three phase mains, and the yoke that permeability magnetic material is made is equipped with in the outside of solenoid; Described pressing plate and flange are austenitic stainless steel; The power frequency of described three phase mains is 50Hz, and current strength is 85-95A; Described graphite centre rod is that tapering is the round platform of 1.2-1.4; The inner chamber of described cooling copper sheathing is installed cooling coil, cooling coil one end through cooling copper sheathing overcoat be connected with air inlet, the other end passes successively cooling copper sheathing inner sleeve, graphite overcoat and is connected with gas outlet, and the inwall of the Way out of described gas outlet and described graphite overcoat is tangent, and the Way out axis of gas outlet and the axis angle of graphite overcoat are less than 90 °; Described air inlet connects inert gas source of the gas.
