A split type continuous casting crystallizer for conductive copper material

Abstract

The invention discloses an electro-conductive copper split type continuous casting crystallizer. The electro-conductive copper split type continuous casting crystallizer comprises an outer assembly and an inner assembly which are made of a rigid and hot good conductor material. The outer assembly is provided with a first channel, the inner assembly is located in the first channel of the outer assembly, a second channel is arranged in the inner assembly, and the outline cross section of the inner assembly is the same as the cross section of the first channel; and the inner wall of the first channel is provided with a first cooling groove, the outer wall of the inner assembly is provided with a second cooling groove, and the first cooling groove and the second cooling groove jointly form a cooling channel. The electro-conductive copper split type continuous casting crystallizer has the advantages that the cooling channel is convenient to machine and good in sealing performance, so that coolant leakage and firing are avoided.

Description

technical field [0001] The invention relates to the technical field of copper processing equipment, in particular to a split-type continuous casting crystallizer for conductive copper materials. Background technique [0002] Conductive copper busbar is a high-current conductive material used in the field of electric power. It is suitable for high-voltage and low-voltage electrical appliances, switch contacts, power distribution equipment, bus ducts and other electrical equipment. It is also often used in the electrolytic smelting industry; the conductive copper busbar has the advantages of low resistivity and large bendability. Conductive copper busbars are mainly produced by continuous casting method to produce bright oxygen-free copper rods, and then the bright oxygen-free copper rods are processed into conductive copper busbars by continuous extrusion molding technology. [0003] The crystallizer used in continuous casting of copper materials is mainly made of metal with...

Problems solved by technology

However, on the one hand, the split type crystallizer consumes a lot of coolant during metal casting, because the cooling channel sealing performance of the crystallizer is insufficient, and part of the coolant will inevitably leak; In the air gap area, a part of the coolant is in an open fire state, which causes the coolant to heat up rapidly, which not only increases the energy consumption of metal casting, but also inevitably produces some ingot quality defects
