Embodiment Construction

[0033] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0034] A process for preparing an ultra-wide copper strip with high precision and controllable shape for transformers, characterized in that it includes the following steps:

[0035] Step 1: Put the copper block raw material into the copper melting tower to dissolve to obtain copper liquid, and then pour the copper liquid into the mold to form an ingot;

[0036] Step 2: melting and drawing the copper block;

[0037] Step 3: Put the copper block into the walking furnace to heat, and after heating, carry out hot rolling to open the embryo to obtain the rough material;

[0038] Step 4: put the rough material into the rough rolling mill for rough rolling;

[0039] Step 5: Put the coarse material that has been rough rolled in...

Abstract

The invention provides a high-precision controllable plate-type ultra-wide copper strip used for a transformer and a production technology of the high-precision controllable plate-type ultra-wide copper strip used for the transformer, and belongs to the technical field of copper strip production. By means of the high-precision controllable plate-type ultra-wide copper strip used for the transformer and the production technology of the high-precision controllable plate-type ultra-wide copper strip used for the transformer, the problem that the performance of copper strips obtained through existing production technologies of the copper strips used for transformers is not high is solved. The production technology comprises the working procedures of ingot casting, pull casting, heating, blank opening, rough rolling, annealing, cleaning, finish rolling, rolling, centering, quality inspection and the like. Compared with the prior art, the production technology has the advantages that the ultra-wide copper strip obtained through the production technology is high in precision standard, wrinkles are avoided in a packaging process, and a quantity inspection process is strict, reliable and accurate.

Description

technical field [0001] The invention belongs to the technical field of copper strip production, and relates to an ultra-wide copper strip with a high-precision controllable plate shape for a transformer and a preparation process thereof. Background technique [0002] As a metal component, copper strip is widely used in various products, such as electrical components, switches, gaskets, spacers, electric vacuum devices, radiators, conductive base materials and automobile water tanks, heat sinks, cylinder plates, etc. kinds of parts. Among them, the copper strip used in the electrical components in the transformer needs high requirements in the preparation process because of its high standard precision requirements, and also requires higher requirements in the packaging process. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the performance of the copper strip obtained by the existing copper strip preparation process for...
