Abstract
The invention discloses a TP2 copper tube up-casting production technology. The technology process comprises the steps of copper electrolyzing, melting, P-Cu and B-Ce adding, heat preservation, up-casting, rolling, cogging drawing, intermediate annealing, drawing, inspection, sizing, inner and outer surface cleaning, flaw detection, bull block drawing, final annealing, clearing, packaging inspection and warehouse entry. After liquid copper melts, a liquid level is covered with charcoal, and the thickness of the charcoal is 20 mm, in this way, oxygen is isolated, oxidization is prevented, and the reducing atmosphere is produced and plays a role in preliminary deoxidation and heat preservation. Heat perversion facilitates uniformity of the solution temperature and ingredients and facilitates melt exhaust. P-Cu adding in steps can allow the P content to be uniform. Working procedures are simpler, so the production cost is lowered, and the yield is improved.
Description
Technical field
The invention belongs to copper tube production process, be specifically related to derivation production. art on a kind of TP2 copper pipe.
Background technology
It is very general at home that up-drawing method produces copper material, and due to its small investment, operation is fast, production process is relatively simple, is one of technique of current many medium-sized and small enterprises first-selection.Up-drawing method is more used in copper rod, plate production, uses less in copper pipe, and particularly producing has the copper pipe of additive then more few use.Reason is to be introduced through the process that journey is a continuous casting, and raw material is constantly adding, and the composition difficulty in whole body of heater realizes stable.Add that continuous casting billet structure is comparatively loose causes the density of pipe lower, inherent quality is difficult to ensure that follow-up large deformation stretches.TP2 copper pipe process many employings horizontal continuous-casting-extruding-drawing process, this production technology investment cost is large, and production cost is high, and lumber recovery is difficult to be stabilized in more than 80%.Whole technological process is complicated, and energy consumption is large, and the cycle is long.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, provide derivation production. art on a kind of TP2 copper pipe, operation is relatively simple, reduces production cost, improves yield rate.
Derivation production. art on TP2 copper pipe provided by the invention, technological process comprises: cathode copper → melt → add P-Cu, B-Ce → be incubated → above draw → rolling → cogging drawing → intermediate annealing → drawing → inspection → scale, surfaces externally and internally cleaning → flaw detection → dish draw → finished products → level → test package → warehouse-in.Wherein, after copper liquid dissolves.Liquid level covers charcoal, charcoal thickness 20mm; Holding temperature is 1116 ~ 1118 DEG C, insulation 20min; On crystallizer gos deep into the copper liquid degree of depth when drawing is 15 ~ 20mm, holding furnace temperature is 1130 ~ 1150 DEG C, melting furnace temperature is 1160 ~ 1170 DEG C, cooling water temperature is 35 DEG C, lock is 70 times/min, and traction voltage is 65V, and leaving water temperature is 50 DEG C, cooling water pressure is 0.7MPa, and skirt speed is 150 ~ 180mm/min; Substep adds P-Cu, in employings slotting method P-Cu is added holding furnace and on draw stove copper liquid depths, segmentation adds B-Ce.
Derivation production. art on TP2 copper pipe provided by the invention, its beneficial effect is, after copper liquid dissolves.Liquid level covers charcoal, charcoal thickness 20mm, and object is the anti-oxidation of starvation, and produces reducing atmosphere, plays pre-deoxidation and insulation effect; Solution temperature and uniform composition are convenient in insulation, and are conducive to melt exhaust; Substep adds P-Cu, and can to realize P content even.Sequence is relatively simple, reduces production cost, improves yield rate.
Detailed description of the invention
Below in conjunction with an embodiment, derivation production. art on TP2 copper pipe provided by the invention is described in detail.
