Problems solved by technology

[0007] The process flow of the above two production methods is relatively long and the yield is low. For example, the yield of 1.0mm copper alloy thin strip is about 60%, and there are defects such as large energy consumption, high metal loss, and high cost. In line with the country's economical society's fundamentals of a strong country
[0008] The applicant unit has applied and implemented the continuous casting and rolling production method in the fields of aluminum and aluminum alloy strips and magnesium and magnesium alloy strips, but the field of copper and copper alloy strips has not been applied and implemented, which is mainly copper and copper The physical and chemical properties of the alloy are very different from those of aluminum and aluminum alloys or magnesium and magnesium alloys. Due to the high melting point, the melting temperature of copper and copper alloys is also high, and the temperature of the solution drops quickly, forming the corresponding production method of continuous casting and rolling. The process parameters and the supporting equipment settings around the process parameters are also very different from the continuous casting and rolling of aluminum and aluminum alloys and magnesium and magnesium alloys.
[0009] It is well known that the continuous casting and rolling production method of copper and copper alloy strips has great social benefits and economic value, but no related reports have been seen so far. The difficulty of solving lies in the process setting and surrounding Technical issues such as equipment matching for process setting

Abstract

Disclosed is a continuous casting-rolling production method for strips of copper and copper alloys. The method comprises a continuous casting-rolling production technology and device configurations related to the continuous casting-rolling production technology, wherein the continuous casting-rolling production technology is generally set as the following seven working procedures: melting-stream guiding-purification-head box-distribution-continuous casting and rolling-winding. The device configurations comprise a melting device, stream guiding devices, a purification device, a head-box device, a distributer device, a continuous casting-rolling machine and a winding device. The connection sequence of the device configurations is: the melting device-a stream guiding device-the purification device-a stream guiding device-the head-box-a stream guiding device-the distributer device-the continuous casting-rolling machine-the winding device. The production method organically combines castingtechnology and rolling technology into one working procedure, and is a novel near-net-shaped processing technology, thereby apparently improving production efficiency of the strips of copper and copper alloys, dramatically decreasing energy consumption and conforming to national industrial development direction.

Description

【Technical field】 [0001] The invention belongs to the technical field of nonferrous metal processing, and in particular relates to a continuous casting and rolling production method of copper and copper alloy strips. 【Background technique】 [0002] Currently known production methods for copper and copper alloy strips mostly adopt the following two methods: [0003] 1. Ingot hot rolling method [0004] Batching and melting - semi-continuous casting "slab" - sawing - heating - hot rolling - milling - cold rolling - annealing - cold rolling - finishing - shearing - product packaging process. [0005] 2. Continuous casting strip billet cold rolling method [0006] Batching and melting - horizontal continuous casting "slab" - milling - sawing - cold rolling - annealing - cold rolling - finishing - shearing - product packaging process. [0007] The process flow of the above two production methods is relatively long and the yield is low. For example, the yield of 1.0mm copper al...
