Description
The utility model relates to a kind of casting equipment that electroslag technology is produced centrifugal casting, particularly portable centrifugal Bohler electroslag tapping device used.
In the conventional centrifugal casting of industrial extensive use is after metal pattern tube with centrifugal casting machine is preheating to uniform temperature, evenly coat the sand that covers of thick 1-3 millimeter at mould tube inwall, the molten metal in the ladle soon of existing side by side is poured running channel into and is flow to mould tube in the rotation, and centrifugal casting hollow after several minutes has just formed.This technology is owing to molten metal two-way solidifying between mould tube inwall and Free Surface, consequently: 1) foundry goods interior solid degree deficiency; 2) field trash in the foundry goods is more.
The eighties, Ukraine's crust electric welding research institute developed the centrifugal electroslag casting technology that is referred to as, and this technology organically combines traditional have lining electroslag refining technology and centrifugal casting technique.Compare with traditional centre spinning method, centrifugal electroslag casting method has following characteristics: (1) slag has replaced coating.In centrifugal Bohler electroslag tapping process, slag is introduced into the metal pattern tube, at first forms the thin slag crust that one deck plays the protection die wall on die wall, and this slag crust separates fully with molten metal, and traditional centrifugal casting easily forms the mixed layer of metal and coating at cast(ing) surface; (2) under action of centrifugal force, slag and molten metal flow in opposite directions, and slag is " refining " molten metal once more, make pernicious gas in the molten metal, field trash not only continue to reduce, and will remains a small amount of field trash dispersion and be spherical; (3) molten metal is in being frozen into the process of foundry goods; surface near mould tube center forms the high temperature slag blanket; stoped molten metal directly to contact with air; not only protected molten metal not oxidized; the more important thing is and play insulation effect; facilitate the directed layering of molten metal course mould tube center position in the die wall to solidify, thereby obtain the metal casting the same with the forging mechanical performance.
Promote the problem that this new technology runs into: the firstth, how to use this technology to combine with induction furnace, how to combine with electric arc furnaces, because these two kinds of stoves one are no synthetic slags, the 2nd, liquid steel temperature has the lining electroslag furnace low; The secondth, fixed have lining electroslag furnace and fixed centrifugal casting apparatus can only man-to-manly unite use, as wanting one, fixed to have the lining electroslag furnace to pour into a mould to the dissimilar centrifugal casting machine that is fixed on the different location respectively be impossible.
The purpose of this utility model is the centrifugal Bohler electroslag tapping device of a kind of movable type of design, and this device can move in the workshop and configuration neatly; The function of smelting synthetic slag is arranged; And have to accept and hold molten metal, secondary function the synthetic slag temperature raising; Also can slag, molten metal be poured into centrifugal casting machine by certain speed.It can be with existing widely used induction furnace, electric arc furnaces, lining electroslag furnace supporting use is arranged, simultaneously be arranged in a line on horizontal cantilever centrifugal casting machine, support roller formula centrifugal casting machine, vertical centrifugal-casting machine, multistation centrifugal casting machine match, thereby solve above-mentioned the problems of the prior art.
The utility model is achieved through the following technical solutions:
Portable centrifugal Bohler electroslag tapping device comprises chassis 17, chassis driving mechanism 15, wheel 16 and track 27.Slag and molten metal hybrid packet 2, slag making temperature raising electrode 24,25,26, transformer 13, electrical control cubicles 14 and tipping mechanism are arranged on chassis 17.Tipping mechanism comprises inclusion turning cylinder 1, supporting plate 3 and the supporting plate elevation mechanism below the sprue gate that is arranged on slag and molten metal hybrid packet 2.The supporting plate elevation mechanism is the steel wire rope winch structure, and it comprises drive motors 12, hoisting mechanism 10,11, column 9, counterweight 8, fixed pulley 5,6,7 and steel wire rope 4.
When portable centrifugal Bohler electroslag tapping device uses, should be before induction furnace (or electric arc furnaces) tapping, in slag and molten metal hybrid packet 2, be ready to synthetic slag, then the molten metal in the induction furnace (or electric arc furnaces) is injected hybrid packet 2, immediately by slag making temperature raising electrode 24,25,26 improve the slag temperature, before meanwhile this device moves to centrifugal casting machine along track 27, drive hoisting mechanism 10 by drive motors 12,11, with steel wire rope 4 pull-ups, thereby affect supporting plate 3 elevate a turnable ladders, is the center to making slag and molten metal hybrid packet 2 with inclusion turning cylinder 1, and slag liquid and molten metal are poured in the centrifugal casting machine.When lining electroslag furnace supporting use is arranged, needn't be equipped with synthetic slag in advance, other steps are same as described above.
The advantage of portable centrifugal Bohler electroslag tapping device is: it can be successfully the induction furnace of centrifugal electroslag casting technology and extensive use, electric arc furnaces, there is the steel-making of lining electroslag furnace to combine, make induction furnace, the electric arc furnaces molten metal again refining to reach the level of electroslag steel, simultaneously, before this device can move to dissimilar centrifugal casting machines neatly, to produce length, short different size high alloy steel pipe, and the special shape profiled member that must adopt vertical centrifugal-casting machine to produce, and on the multistation centrifugal casting machine, once cast out a plurality of high-quality foundry goods that reach the forging level.
