Abstract
A process for producing oxygen-free copper from impurity-contained red copper includes such technical steps as screening impurity-contained red copper, packing, smelting, adding intermediate rare-earth alloy, pouring into oxygen-free copper melting furnace, keeping temp constant, drawing and reeling. Its special apparatuses include a float ball device which jalong with delivery tube moves synchronously with the level in temp-keeping furnace, and a smelting furnace for smelting impurity-contained red copper, which is above smelting furnace and close to line-frequency furnace. Its advantages are simple technique and less consumption of energy.
Description
The present invention relates to the purple composition brass of a kind of usefulness and produce the method and the corollary apparatus thereof of oxygen free copper.
Producing oxygen free copper at present is through there being core main frequency furnace melting-deoxygenation-insulation-traction-rolling to be finished product with No. 1 electrolysis copper coin.Can not be with purple composition brass direct production oxygen free copper, but use round-about way, promptly earlier purple composition brass is packed → melted → be cast into positive plate → be electrolyzed to produce electrolytic copper → input smelting furnace melting → deoxygenation → insulation → traction → rolling.Its shortcoming is a complex procedures, and the cycle is long, copper loss height in the production, and energy consumption is many, pollute to weigh, and the product of producing does not often reach the national standard requirement.
The purpose of this invention is to provide method and corollary apparatus that the purple composition brass direct production of a kind of usefulness goes out to reach the oxygen free copper product of GB requirement.
Task of the present invention is finished as follows, its technical process is: purple composition brass is through screening pack → enter smelting furnace melting → add rare earth intermediate alloy → pour into oxygen free copper smelting furnace → holding furnace → traction → rolling at 1100-1200 ℃, its support equipment be in the holding furnace that the core line frequency induction furnace is arranged, increase by one with tubing synchronously with the floating ball device of liquid surface lifting, above a side of smelting furnace, increase the smelting furnace (being coreless power frequency induction furnace) of the purple composition brass of a melting, coreless power frequency induction furnace is by there being core line frequency induction furnace one side, there is the converter nose of pouring smelting furnace into towards outside the top, bottom has hinge to connect with pedestal, and the smelting furnace top is communicated with and connects liquid bath.
The present invention has following effect: in original oxygen free copper production unit, increase this supporting device and use this method, can directly produce the oxygen free copper product that meets GB3952.2-89 continuously with purple composition brass, and minimizing operation, energy-saving and cost-reducing, reducing and pollute, is to utilize waste and old purple composition brass resource to produce the optimal path of oxygen free copper.
Fig. 1 is a structural representation of the present invention;
To describe embodiment in detail below in conjunction with accompanying drawing.
The present invention produces the technology of oxygen free copper and the improvement of equipment to the purple composition brass of existing usefulness, at first aspect equipment, it includes one has the core line frequency induction furnace and leads the equipment of pulling out, in the holding furnace 9 that the core line frequency induction furnace is arranged, increase by one and lead to the tubing 8 that leads the equipment of pulling out, synchronous floating ball device 10 with liquid surface lifting is arranged on the tubing 8, it above a side of smelting furnace 6 smelting furnace 2 of the purple composition brass of melting, smelting furnace 2 bottoms have hinge 4 to be connected on the pedestal 12 by core line frequency induction furnace one side is arranged, and connect liquid bath between smelting furnace 6 tops and the smelting furnace 2.During work, earlier purple composition brass is screened, remove deleterious metal,, with packing machine purple composition brass is packed again as iron, tin, lead etc., drop into the interior melting of a smelting furnace (being coreless power frequency induction furnace), when temperature during at 110-1200 ℃, in copper liquid, add rare earth intermediate alloy, copper liquid is stirred, under the effect of rare earth intermediate alloy, quicken deoxidation slag making, refinement copper crystal grain, thereby improve the electrical property and the mechanical property of copper.With above-mentioned copper liquid after the reduction deoxidation, removing petticoat pipe 1 smoke abatement, the removal of impurities of skimming, connect liquid bath 5 from can be in hinge 4 rotates the smelting furnace 2 that tilts pouring into through converter nose 3, flow into smelting furnace 6 again, flow in the holding furnace 9 through the communicating aperture 11 of smelting furnace 6 below holding furnace 9 central dividing plates 7 again.Then by the tubing 8 with floating ball device 10 liftings be extracted into lead lead in the equipment of pulling out pull out, rolling, can pack warehouse-in.
Claims (2)
1, purple composition brass is produced the method for oxygen free copper, and its technical process is: the melting of purple composition brass screening packing → input smelting furnace → and in 1100-1200 ℃ of adding rare earth intermediate alloy → pour into oxygen free copper smelting furnace → holding furnace → traction → rolling.
2, purple composition brass is produced the corollary apparatus of oxygen free copper, it includes one has the core line frequency induction furnace and leads the equipment of pulling out, it is characterized in that: in the holding furnace that the core line frequency induction furnace is arranged, have and lead to the tubing that leads the equipment of pulling out, synchronous floating ball device with liquid surface lifting is arranged on the tubing, it above a side of its smelting furnace the smelting furnace of the purple composition brass of melting, the smelting furnace bottom connects liquid bath by there being core line frequency induction furnace one side hinge-coupled to be arranged on pedestal between smelting furnace top and the melting.
