Abstract
Copper and copper alloy section tube preparation method and equipment, with vacuumize respectively, direct water filling chilling and add measure such as trace element, raw material once can be cast can direct applied big length copper and copper alloy section tube, thereby has reduced cost and equipment investment.
Description
The present invention is the production technology of a kind of copper and copper alloy section tube, and has invented a kind of new equipment new technology is implemented.Specifically the present invention relates to a hole or a plurality of hole, wall thickness equates or does not wait that hole and verandah have the production method or the equipment of the special section tubular product of circle or non-circular curve.
The production technology of domestic special section tubular product consists essentially of ingot casting, operations such as cut-out, perforation, heating, extruding, drawing, pickling, and what have also will be through intermediate annealing.The shortcoming of existing technology is that 1. the extruder investment is big, the expense height, and extrusion yield is low; 2. operation is many, and mould is many, the percent defective height, and the cost height, the special-shaped section that has can not once be extruded into, must be through a few procedure transition; 3. extrusion is because each extrusion billet weight is limited, so the special section tubular product limited length of producing is difficult to the length supply of material by customer requirements, if length is not enough, will weld lengthening in the use, not only cause trouble to the user, main is the danger that increases seepage; 4. the shape tube of some specifications and models such as rectangle eccentric pipe are difficult to produce with extrusion, even can't produce, and have to adopt other cross sectional shape to replace.Abroad also be to adopt extrusion to produce shape tube.
The top continuous metal cast process that Finland's Japan Patent is spoken of can be produced special-shaped pipe, method is that a vacuum chamber is inserted in the crystallizer top, in vacuum chamber, is furnished with cut-out, withdrawing device, this brings very big trouble just for the production of big length pipe, because vacuum plant is very big, and it is not easy to operate, more difficult when frequent replacing kind, also having a kind of method in addition is that crystallization portion is down sunk to copper under water, though do not vacuumize like this, but need large-scale electric furnace, certain liquid depth requirement is arranged, and not too safe, and casting pressure is little, be difficult to adjust, so product quality is difficult for guaranteeing
The purpose of this invention is to provide a kind of Processes and apparatus, be more suitable for the middle-size and small-size factory and the variety production that manys than existing manufacturing technique and equipment.Can significantly reduce cost, reduce production process, shorten the production cycle, save equipment investment; The present invention also aims to utilize this equipment directly raw material to be processed into without other section deformation, with regard to direct applied big length copper of energy and copper alloy section tube material, be devoted to improve the performance of copper and copper alloy section tube, make it have desired shapes and dimensional tolerance, higher fineness, the crystal grain of refinement.
Production technology of the present invention is added the rare earth element of 0.001%-0.008% in copper and copper alloy solution, weakened the effect of micro-objectionable impurities, improved the performance of copper and copper alloy section tube, the present invention locates copper and the direct water filling chilling of copper alloy section tube at (A), strengthened the thermograde on crystal region top, pull rate is greatly improved, because crystallization rate is accelerated, crystal grain has obtained refinement.In order to make crystal plane remain on copper and to need a pressure differential more than the copper alloy liquid level, this process using vavuum pump vacuumizes respectively copper and the copper alloy section tube inside in crystallizer (1) and the casting, vavuum pump and crystallizer (1) and copper and copper alloy section tube (7) head connect with flexible pipe (9), and there is seal nipple (12) at the flexible pipe two ends.
Continuous casting equipment of the present invention mainly contains speed change part, vibration part, adjustable clamping tractive unit part, frame part and vacuum partly.Speed change is partly rotated by chain power transmission shaft (3) by a speed-regulated DC motor, reduction box; Vibration partly is to drive cam by another speed-regulated DC motor to hit the chain pilled-in selvedge, and power transmission shaft (3) is intermittently rotated; Adjustable clamping tractive unit part is made up of idle wheel (4) in the middle of a pair of and a pair of above gear nip rolls (2), idle wheel (4) rotated in the middle of power transmission shaft (3) drove, a pair of above gear nip rolls (2) clamps copper and the copper alloy section tube in the casting and intermittently rotates upwards traction synchronously, to directly different pipe clamps when tight, the position of gear nip rolls (2), can pass through slide block (6) and pass through Luo Ding (5) adjustment, gear nip rolls this moment (2) changes slightly with the centre-to-centre spacing of middle idle wheel (4), but, can not influence the transmission of its clamped condition tractive force because the modulus of gear is enough big; Frame partly is made up of column and rocking arm, and adjustable clamping tractive unit part and crystallizer (1) are installed on the rocking arm; Vacuum partly is made up of vavuum pump, pipe winding wheel (10), flexible pipe (11) and seal nipple (12), owing to be directly copper and copper alloy section tube (7) inside in crystallizer (1) and the casting to be vacuumized, this has just saved huge vacuum chamber and cut-out, extraction device, makes the work of vacuumizing become very convenient.
Copper of the present invention and copper alloy section tube continuous casting process and equipment, can cast polytype copper and copper alloy section tube, and needn't carry out big adjustment, vibration frequency and hauling speed all can be on a large scale step-less adjustment, this just selects for the best processing parameter of multiple pipe and adjustment has brought convenience.
