Description

technical field [0001] The invention relates to the technical field of copper processing equipment, in particular to an automatic control device for cold water water pressure for copper processing. Background technique [0002] The upward lead continuous casting machine is a large-length bright oxygen-free copper rod production equipment, which has the advantages of high production efficiency and good production continuity; the upward lead continuous caster is mainly composed of raw copper melting furnace, upward lead continuous casting crystallization in structure The continuous casting crystallizer sucks the molten copper liquid in the melting furnace through vacuum negative pressure, and then crystallizes the molten copper liquid into solid copper through the rapid cooling of the cooling water channel, so as to obtain large-length bright Oxygen-free copper rod.

AI Technical Summary

Problems solved by technology

The flow rate and temperature of the cooling water in the upward continuous casting crystallizer need to be strictly controlled, because different microscopic metallographic structures will be produced during the crystallization of molten copper liquid under different cooling conditions; when the temperature of the cooling water inlet is stable , 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 be incomplete, 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.

[0003] In the prior art, the water pressure is mainly adjusted by adjusting the power of the water pump, so as to control the flow rate of the cooling water, that is, the temperature of the water outlet. However, the power adjustment structure of the water pump is complicated, and the power of the water pump is not completely linearly related to the water pressure. , so there are large errors and fluctuations in the adjustment, which affects the stability of the production quality of the upward continuous casting machine
