Description

Technical Field

[0001] The present invention relates to the technical field of metal strips, and particularly relates to a high-precision special-shaped strip and an annealing anti-sticking tape process therefor. Background Art

[0002] Metal materials generally refer to pure metals or alloys in industrial applications. The properties of metal materials are generally divided into two categories: process properties and service properties. The so-called process properties refer to the properties shown by metal materials under the specified cold and hot working conditions during the machining and manufacturing process of mechanical parts. The quality of the process properties of metal materials determines their adaptability to processing and forming during the manufacturing process. Due to different processing conditions, different process properties are required, such as casting performance, weldability, forgeability, heat treatment performance, machinability, etc. The so-called service properties refer to the properties shown by metal materials under service conditions of mechanical parts, including mechanical properties, physical properties, chemical properties, etc.

[0003] A metal strip is a kind of metal material, usually having a flat shape and a relatively thin thickness. It can be various metal materials, including iron, steel, copper, aluminum, zinc, etc. Metal strips are usually made by processing techniques such as rolling or stretching, and have specific dimensions and shapes. However, in the actual processing of existing metal strips, the production efficiency is not high, so it cannot meet the production needs of enterprises.

[0004] Therefore, we propose a high-precision special-shaped strip and an annealing anti-sticking tape process therefor. Summary of the Invention

[0005] The main purpose of the present invention is to provide a high-precision special-shaped strip and an annealing anti-sticking tape process therefor. Through the cooperation between the above procedures, it is possible to realize one-time heating and cooling operations for the high-precision special-shaped strip, thereby improving the working efficiency of the annealing operation of the metal strip. Through the brushing operation, it is possible to remove the oxides and oil stains adhering to the surface of the high-precision special-shaped strip generated by the previous process, and reduce the labor intensity of the operator when cleaning the residues on the surface of the high-precision special-shaped strip subsequently, and can effectively solve the problems in the background art.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A high-precision special-shaped strip and an annealing anti-sticking tape process therefor. In the high-precision special-shaped strip and the annealing anti-sticking tape process of the present invention, it includes a high-precision special-shaped strip body 1. Both ends of the high-precision special-shaped strip body 1 are provided with end heads 101. The high-precision special-shaped strip body 1 includes base metals and noble metals.

During profile drawing, it is divided into transition profile drawing and finished product profile drawing. All sizes are controlled by the profile drawing of the high-precision profiled strip annealing anti-sticking tape, and the profile drawing speed is 0 - 80 m / min.

[0017] By adopting the above technical solutions, it can ensure that the high-precision profiled strip wound into a coil does not loosen, prevent the occurrence of cross-strip phenomenon of the high-precision profiled strip. When annealing, introducing a protective gas or vacuum annealing can ensure that the surface of the high-precision profiled strip annealing anti-sticking tape is free of oxidation, improve the product quality and production efficiency of the high-precision profiled strip annealing anti-sticking tape, and at the same time effectively control the rejection rate of the high-precision profiled strip annealing anti-sticking tape, thereby meeting the production requirements of the enterprise.

[0018] Specifically, in S1, the manufacturing method of the high-precision profiled strip includes the following steps:

[0019] (1) First, perform surface treatment on the noble metal blank and the base metal. Immerse it in a 15% - 20% dilute sulfuric acid solution to remove the oxides of the substrate itself, and then perform mechanical polishing to meet the surface requirements before compounding;

[0021] (3) For the rolled product, longitudinal shearing is performed according to the finished product size requirements, and the longitudinally sheared product is placed on a coiling reel for coiling.

[0022] Specifically, in S5, when the high-precision profiled strip is coiled, there is a certain coiling tension between the coiling device and the rolling mill to ensure that the high-precision profiled strip coiled into a disk does not become loose and prevent the occurrence of cross-strip phenomenon in the high-precision profiled strip.

Immerse them in a 15% - 20% dilute sulfuric acid solution to remove the oxides on the substrate itself, and then perform mechanical polishing to meet the surface requirements before compounding. (2) Then, perform controlled atmosphere solid-phase rolling on these two materials at a temperature of 500 - 750 °C, with a strip processing speed of 1 - 2.5 m / min and a rolling deformation of 35% - 60%. (3) For the rolled product, perform longitudinal shearing according to the finished product size requirements, and place the longitudinally sheared product into a winding disc for winding.

4. A high-precision special-shaped strip annealing anti-sticking tape processing process according to claim 2, characterized in that, In S5, when winding the high-precision profiled strip, there is a certain winding tension between the winding device and the rolling mill to ensure that the high-precision profiled strip wound into a disc does not become loose and prevent the occurrence of cross-strip phenomenon of the high-precision profiled strip.

5. The processing technology of an anti-sticking tape for annealing of a high-precision profiled strip according to claim 2, characterized in that, In S6, the annealing temperature of the high-precision profiled strip is 400 - 600 °C. During annealing, it must be placed in a protective gas or vacuum annealing to ensure that the surface of the high-precision profiled strip is free of oxidation.
