Description
Technical field
The present invention relates to nonferrous materials processing technique field, a kind of copper more particularly, to diameter less than 15mm and its
The production technology of alloy bar material.
Background technique
The production technology of copper of traditional diameter less than 15mm and its alloy bar material are as follows:
Process flow 1: founding garden ingot → sawing → extruding copper and its alloy bar material → sawing → pickling → are aligned → are tied up
Packaging；
Process flow 2: founding garden ingot → sawing → extruding bar stock → sawing → pickling → vertical bar stretches (can be with multi-pass)
→ aligning → scale sawing → finished products → enlacement packaging；
Due to the processing characteristics difference of different-alloy, the production technology of traditional minor diameter copper and its alloy bar material is for producing
When certain alloys, manifest that process is too long, the excessively high drawback of functions of the equipments demand.Below with QSn6.5-0.1 and QSn7-0.2 tin
For the production of phosphor bronze Thin-diameter rod, it is illustrated:
QSn6.5-0.1 and QSn7-0.2 tin-phosphor bronze bar can carry out hot extrusion processing, but the hot extrusion performance of the alloy
There is its particularity.Consult metallurgical industry publishing house " heavy non-ferrous metal material processes handbook " (the 4th fascicle, P38) alloy bar material
The forward extrusion metal rate of outflow allowable only 0.03~0.06 meter per second, the requirement in various copper and copper alloy, to extrusion speed
It is most slow one of alloy.In specific production practices, it is believed that QSn6.5-0.1 and QSn7-0.2 tin-phosphor bronze bar hot extrusion
Pressing element is difficult.The garden ingot system of a certain extruder can be squeezed because being limited by the tin-phosphor bronze forward extrusion metal rate of outflow
Tin-phosphor bronze stick diameter out has a lower limit.For example, the φ 245mm extrusion system of 40MN hydraulic press, it is squeezable
Minimum QSn6.5-0.1 and QSn7-0.2 tin-phosphor bronze stick diameter is φ 55mm, and can not squeeze the bar stock less than φ 55mm.Such as
The bar stock for being less than φ 55mm is squeezed, then easily occurs squeezing crackle, it can not output qualified products.
If demand diameter is less than QSn6.5-0.1 the and QSn7-0.2 tin-phosphor bronze bar of 15mm, by traditional mode of production work
Skill need to then squeeze bar stock from φ 55mm and carry out multi-pass stretching, and stretching passage is excessive, and process is too long.Or use small extruding garden
Ingot system, then production efficiency is extremely inefficient.
In view of the foregoing, the production technology of a kind of copper of diameter less than 15mm and its alloy bar material is now developed.
Summary of the invention
Purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of copper of diameter less than 15mm and its conjunction
The production technology of golden bar, present invention diameter produced are less than the copper and its alloy bar material of 15mm, are particularly suitable for hot extrusion
Difficult alloy is processed, compared with traditional handicraft, is not limited by single ingot casting weight, production efficiency can be improved.
The present invention to achieve the goals above, adopts the following technical scheme that a kind of diameter is less than the copper and its alloy of 15mm
The production technology of bar, horizontal casting bar stock → sawing → production tensioning chuck → whole diameter stretches → strip off the skin stretching → intermediate annealing
→ pickling → tube reducing stretching → aligning → finished products → inspection, detection and packaging.
The first step, horizontal casting bar stock: carrying out horizontal type level continuously casting using Ajax-Wyatt furnace, casts setting specification
Casting rod base, smelting temperature: 1150~1250 DEG C, casting speed: 25~30m/h, chemical component meet GB5231-2012；
Second step, sawing: sawing casting rod base is at required length；
Third step, make tensioning chuck: every bar stock makes tensioning chuck, according to the tonnage of postorder stretching-machine, stretches folder
Head production length is 100~150mm；
4th step, whole diameter stretch: stretching to bar stock, reduce the diameter of bar stock；
5th step, strip off the skin stretching: being stripped off the skin using stretching-machine to bar stock, to remove bar stock surface casting flaw, is stripped off the skin
It stretches at least once, each diameter reduces by 1~2mm, and the stretching that strips off the skin is gradually reduced the diameter of bar stock.
6th step, intermediate annealing: bar stock is put into annealing furnace by the gross, at 250~300 DEG C of temperature, keeps the temperature 55~65 minutes,
630~650 DEG C are warming up to, keeps the temperature 90~120 minutes；
7th step, pickling: bar progress sulfuric acid is washed, is washed by the gross；
8th step, tube reducing stretch: using at least two passages are stretched on chain type stretching-machine, each diameter reduces 1mm,
The modular angle of stretching die: 6 °~12 °；The process circulation that intermediate annealing, pickling and tube reducing stretch at least once, be finally stretched to
Diameter is less than the trimmed size bar of 15mm；
Aligning: 9th step trimmed size bar obtained is aligned；
Tenth step, finished products: at 250~280 DEG C of in-furnace temperature of annealing, trimmed size bar by the gross is put into annealing furnace
It is interior, keep the temperature 100~120 minutes；
11st step checks, detects and packs: checking surface quality, the size of bar, detects final performance are as follows: and Rm >=
470Mpa, A >=13% after meeting production requirement, carry out finished product packing.
The beneficial effects of the present invention are: present invention diameter produced is less than the copper and its alloy bar material of 15mm, it is especially suitable
Difficult alloy is processed for hot extrusion, compared with traditional handicraft, is not limited by single ingot casting weight, and production effect can be improved
Rate.
