Water pressure-adjustable cooling water system of upcasting continuous casting machine

Abstract

The invention discloses a water pressure-adjustable cooling water system of an upcasting continuous casting machine. The water pressure-adjustable cooling water system comprises an upcasting continuous casting crystallizer, and a crystallizing channel is vertically arranged in the upcasting continuous casting crystallizer. An input water distributing channel and an output water distributing channel are arranged at the upper end of the upcasting continuous casting crystallizer, and a bottom connecting channel is arranged at the lower end of the upcasting continuous casting crystallizer. The input water distributing channel, the output water distributing channel and the bottom connecting channel are all circular and are coaxial with the crystallizing channel. The input water distributing channel and the bottom connecting channel are connected through a plurality of vertical water inlet channels, and the output water distributing channel and the bottom connecting channel are connected through a plurality of vertical water outlet channels. The input water distributing channel and the output water distributing channel are connected with a cooling water inlet pipe and a cooling water outlet pipe correspondingly. According to the water pressure-adjustable cooling water system, the cooling effect stability of the upcasting continuous casting crystallizer can be improved.

Description

technical field [0001] The invention relates to the technical field of copper processing equipment, in particular to a cooling water system with adjustable hydraulic pressure for an upward continuous casting machine. Background technique [0002] Upward continuous casting machine is a production equipment for large-length bright oxygen-free copper rods, which has the advantages of high production efficiency and good production continuity; The up-drawing continuous casting crystallizer sucks the molten copper in the melting furnace through vacuum negative pressure, and then through the rapid cooling of the cooling water channel, the molten copper crystallizes into solid copper, thus obtaining a large length of bright Oxygen-free copper rod. Most of the cooling water channels in the upward leading continuous casting crystallizer in the prior art are cooling water chambers, and then the water inlet pipe and the water outlet pipe are connected to the cooling water chamber. The ...

AI Technical Summary

Problems solved by technology

Most of the cooling water channels in the upward leading continuous casting crystallizer in the prior art are cooling water chambers, and then the water inlet pipe and the water outlet pipe are connected to the cooling water chamber. The cooling water channel with the above structure is not conducive to the orderly flow of water flow, and part of the cooling water will Staying in the cooling water cavity for a long time, and part of the cooling water flows out of the cooling water cavity before fully absorbing heat, so the cooling effect is unstable

[0003] In addition, the cooling water flow rate and temperature in the upward continuous casting crystallizer need to be strictly controlled, because different microscopic metallographic structures will be produced during the crystallization process of molten copper liquid under different cooling conditions; Under normal circumstances, the faster the flow rate of cooling water, the lower the water temperature at the water outlet; if the water temperature at the water outlet is too high, the cooling and crystallization of the copper rod will not be complete, and the water temperature at the water outlet is too low, which is not conducive to the uniformity of the internal metallographic structure of the copper rod.
