Abstract
The invention discloses a process for recombining non-corrosive steel / cotton bimetal rod which comprises the steps of , press-loading the red copper rod into a stainless steel tube, heating the composite metal rod in a heating-furnace, rolling the composite metal rod on a rolling mill according to the required dimensions, thermal straightening the rolled composite metal rod.
Description
Technical field
The present invention relates to the compound process of a kind of stainless steel/copper metal bar.
Background technology
At present, be used for the environment for use that chemical industry and other requirement have corrosion-resistant and high conduction, thermal conductivity, that uses has a stainless steel/copper metal bar, the structure of this compound bar is the outer stainless steel that coats, and internal layer is the copper core, and the cross section is to have the rectangle of specific dimensions and the shape that combines of two cambered surfaces, be that the cross section is that the rectangle with specific dimensions combines with two cambered surfaces, the size in the cross section of copper: the long 10～70mm of rectangle, wide 8～30mm, the radius of two cambered surfaces are 5～16mm.The stainless steel layer of outsourcing and the copper of internal layer are combined closely, stainless steel thickness 1～3mm uniformity.This compound bar is used for the conductive cathode of chemical industry.The production method of stainless steel/copper metal bar has casting, explosive welding and other processing method.The shortcoming of casting production is: in the made stainless steel/copper metal bar bubble arranged, accompany impurity, interface between stainless steel and the copper produces shrinks, and final products also need to remove dead head etc., therefore of poor quality, yield rate is low, and product approval is poor.And there is following problem in explosive welding (EW) by composite methods: blast causes that surface quality is poor, need carry out surface quality processing type shape and handle, and secondly cost is higher, and operation is long.
Summary of the invention
The purpose of this invention is to provide that a kind of flow process is short, method is easy, cost is low, be fit to very much the compound process of stainless steel/copper metal bar of industrialized mass.It is firm that the made stainless steel/copper metal bar of this method has the interface, dense internal organization, advantage such as surface quality is good.
For achieving the above object, the present invention takes following technical scheme:
The compound process of a kind of stainless steel/copper metal bar, this method comprises the steps:
(1) use stainless steel pipe and red copper bar to be raw material;
(2) red copper bar is fitted in the stainless steel tube, stainless steel pipe and red copper bar are tight fit;
(3) will press-fit good composite-metal rod and put into the heating furnace heating, heating-up temperature is 700-1000 ℃, and temperature retention time is 10-150 minute;
(4) size that composite-metal rod is placed on the milling train as requested is rolled;
(5) under 700-980 ℃ of temperature conditions, the composite-metal rod after rolling is carried out thermal straightening, promptly make the stainless steel/copper metal bar.
In the compound process of above-mentioned stainless steel/copper metal bar, between described step (1) and step (2) also (1 ') in steps, promptly stainless steel tube and red copper bar are given processing.Giving processing mainly is that cleaning is carried out on the surface of stainless steel tube and red copper bar.
In the compound process of above-mentioned stainless steel/copper metal bar, this method also comprises step (6), will make the stainless steel/copper metal bar and carry out post processing, is about to the stainless steel/copper metal bar and cleans in pickle, cut scale, repair material, the ultrasonic examination inspection.Pickling mainly is to the composite-metal rod flush away oxide skin etc. in pickle behind compound, aligning.Through the ultrasonic examination inspection, is to check that the bimetallic interface is in conjunction with situation to composite-metal rod.
In the compound process of above-mentioned stainless steel/copper metal bar, in the described step (3), heating-up temperature is preferably 800-900 ℃.And temperature retention time to be quantity, weight according to metal bar decide, metal bar quantity is many more, temperature retention time is just long; Metal bar weight is heavy more, and temperature retention time is also just long.
In the compound process of above-mentioned stainless steel/copper metal bar, in the described step (3), the temperature of thermal straightening is preferably 800-900 ℃.
Advantage of the present invention is: under process conditions of the present invention, be basically on a procedure, realized stainless steel one copper rod compound, simultaneously compound bar has reached the shape of regulation and the size of requirement.Wait other bimetallic complex methods to compare with casting and processing, it is firm that the made stainless steel/copper metal bar of process of the present invention has in the compound bar stainless steel one a bronze medal combination interface, dense internal organization, advantages such as surface quality is good, simultaneously because technological process is short, method is easy, and cost is low etc., is fit to very much industrialized mass.In addition, it is compound that combination process of the present invention is suitable for the sharp copper bi-metal of stainless steel of similar following geomery requirement.The cross section is the shape that rectangle combines with two cambered surfaces.Size range is: the cross section of copper is of a size of the long 10～70mm of rectangle, wide 8～30mm; The radius of two cambered surfaces is 5～16mm; The stainless steel layer of outsourcing and the copper of internal layer are combined closely, stainless steel thickness l～3mm uniformity.
The specific embodiment
Embodiment
Adopting stainless steel pipe and red copper bar is raw material, and the internal diameter of stainless steel pipe is a tight fit with cooperating of the external diameter of red copper bar.Earlier the sharp red copper bar of stainless steel tube is carried out the processing of giving of cleaning surfaces.Adopt artificial then or pressing machine is fitted in red copper bar in the stainless steel tube.To press-fit good composite-metal rod again and put into the heating furnace heating, heating-up temperature is 900 ℃, decides and temperature retention time is quantity, a weight according to metal bar, in the present embodiment, adopt a metal bar to heat in heating furnace, temperature retention time is 10 minutes.The size that then composite-metal rod is placed on the milling train as requested is rolled.Under 800 ℃ of temperature conditions, the composite-metal rod after rolling is carried out thermal straightening again, promptly make the stainless steel/copper metal bar.At last, to make the stainless steel/copper metal bar and carry out post processing, being about to the stainless steel/copper metal bar cleans in pickle, flush away oxide skin etc., cut scale, repair material, and composite-metal rod carried out the ultrasonic examination inspection, check that the bimetallic interface in conjunction with situation, promptly makes qualified stainless steel/copper metal bar.
