It includes columniform graphite jig main part, graphite cover and asbestos cover, and the graphite jig main part is opened has the vertical middle hole that link up, and install in the graphite cover bottom of the copper endotheca of crystallizer to inlaying between copper endotheca and the graphite cover and being equipped with the asbestos cover, graphite cover, asbestos cover back and copper endotheca threaded connection are passed from bottom to top in proper order to the upper end of graphite jig main part, the middle hole of copper endotheca and the middle hole UNICOM of graphite jig main part, and its characterized in that: it still includes the copper protective sheath, the whole cladding of copper protective sheath in the lower extreme of graphite cover, graphite jig main part stretches out the part of graphite cover.
Description
Technical field
The utility model relates to the processing tool field of oxygen-free copper bar, especially relates to the processing tool field adopting UPCAST to produce oxygen-free copper bar, is specially a kind of graphite jig for up-drawing method crystallizer.
Background technology
Up-drawing method produces oxygen-free copper bar, that cathode copper is fused into liquid through power frequency induction furnace, through holding furnace, copper liquid temperature is controlled in prescribed limit, by conticaster quick crystallisation by cooling thus continuously produce oxygen-free copper bar in a crystallizer after copper liquid enters graphite jig.Along with the market demand, in order to improve performance, the copper alloy circle line application that the copper alloy bar adding other metallic element is produced as blank is more and more extensive.And existing graphite jig comprises columniform graphite jig main body, asbestos cover and graphite cannula, wherein graphite jig main body has vertically through middle endoporus, crystallizer to be installed in graphite cannula and to be embedded with asbestos cover between crystallizer and graphite cannula, graphite jig main body is threaded with the copper inner sleeve of crystallizer through after graphite cannula, asbestos cover from bottom to top successively, thus make the middle endoporus UNICOM of the middle endoporus of pipe in copper and graphite jig main body, see accompanying drawing 1.In common oxygen-free copper bar production process, molten alloyed copper in holding furnace comes to completely cut off with extraneous air by one deck graphite flakes of surface coverage, but molten alloyed copper surface still can mix slag and oxide, when the graphite jig being equipped with crystallizer stretches into molten alloyed copper, first the lower end of columniform graphite jig main body is stretched in molten alloyed copper, now be deposited in the slag on molten alloyed copper surface and oxide to form oxide and stick on the middle inner hole wall of graphite jig main body along with molten alloyed copper is mixed in the middle endoporus of graphite jig, thus affect the quality of the copper alloy bar made.
Summary of the invention
For the problems referred to above, the utility model provides a kind of graphite jig for up-drawing method crystallizer, and it can solve the slag on existing graphite jig molten alloyed copper surface when putting into molten alloyed copper and oxide and easily enters the middle endoporus of graphite jig main body and affect the problem of copper alloy bar quality.
Its technical scheme is such, it comprises columniform graphite jig main body, graphite cannula and asbestos cover, described graphite jig main body has vertically through middle endoporus, the bottom of the copper inner sleeve of crystallizer is installed in described graphite cannula, and be embedded with described asbestos cover between described copper inner sleeve and described graphite cannula, the upper end of described graphite jig main body is from bottom to top successively through described graphite cannula, be threaded with described copper inner sleeve after asbestos cover, the middle endoporus of described copper inner sleeve and the middle endoporus UNICOM of described graphite jig main body, it is characterized in that: it also comprises copper protective sleeve, described copper protective sleeve integral coating is in described graphite cannula, the part of described graphite cannula is stretched out in the lower end of described graphite jig main body.
Further, the bottom of described copper protective sleeve is the conical surface.
Further, the thickness of described copper protective sleeve is 0.2mm ~ 0.3mm.
After adopting graphite jig of the present utility model, it is completely cut off by the bottom inlet external environment of copper protective sleeve by graphite jig main body, when the graphite jig being equipped with crystallizer stretches into the molten alloyed copper of holding furnace, molten alloyed copper surface graphite flakes is pushed open and first copper protective sleeve is contacted with molten alloyed copper by copper protective sleeve laterally, thus the slag being mingled in molten alloyed copper surface is separated with oxide and graphite jig main body, slag and the oxide of effectively avoiding being mingled in molten alloyed copper surface enter into graphite jig and stick to the problem of middle endoporus, ensure that the quality of production of copper alloy bar, and the bottom of copper protective sleeve is set to taper surface, the graphite flakes that fast and effeciently just can cover copper alloy surface is pushed open to both sides, thus avoid graphite flakes to enter in graphite jig main body after the fusing of copper protective sleeve, guarantee the quality of production of copper alloy bar further, in addition, the thickness of copper protective sleeve is set to 0.2mm ~ 0.3mm, can ensure copper protective sleeve in the molten alloyed copper of holding furnace rapid melting, can protect in the middle endoporus of graphite jig main body again, graphite cannula surface do not adhere to slag and oxide, further ensure that the quality of production of copper alloy bar.
Accompanying drawing explanation
