Problems solved by technology
Because the bottom of the graphite mold is too wide and it has to work at a high temperature of 1150°C for a long time, the graphite mold will expand and shrink with temperature fluctuations. Due to the insufficient strength of the mold, either the thickness of the copper strip blank produced is uneven, or the mold is two-dimensional. The side cracks, which will damage the mold and affect the normal production of copper strip embryos

The invention discloses an upward continuous casting machine of a superwide copper strip blank, comprising a smelting furnace, heat preserving furnaces, the upward continuous casting machine arranged above the heat preserving furnaces, inductors, a variable frequency coreless winding machine and a graphite mould. The upward continuous casting machine of the superwide copper strip blank is characterized in that both sides of the smelting furnace are respectively provided with the heat preserving furnaces; the inductors are respectively arranged at the bottoms of the heat preserving furnaces and the smelting furnace; the upward continuous casting machine is provided with two drawing heads; each drawing head is connected with a crystallizer; the graphite mould is in a rectangular shape, and a C-shaped clamp is arranged on the graphite mould and fixed by using a bolt. The invention has the advantages of simple structure and long service life, realizes the short process of the superwide copper strip blank, achieves the energy saving, the emission reduction and the low carbon; in addition, the superwide copper strip blank produced by using the upward continuous casting machine has uniform thickness and stable quality.
Description
technical field [0001] The invention belongs to the technical field of copper processing, in particular to an ultra-wide type copper strip blank up-drawing continuous casting machine. Background technique [0002] Due to the small specifications of the current copper strip billet up-leading continuous casting machine, the width is generally below 380mm, and the output is low below 15 tons per day, so a single-set up-leading multi-head continuous casting machine with two furnaces integrated is generally used. With the continuous expansion of the market economy and the continuous innovation of short-process copper processing technology, customers' requirements for the width and output of upward continuous casting copper strip blanks are also continuously increasing. In order to meet the market demand, the biggest problem lies in the graphite mold installed on the crystallizer to produce 400-650mm ultra-wide copper strip blanks. Because the bottom of the graphite mold is too w...
