Red copper furnace drawing water pressure stabilization control system

Abstract

The invention relates to the technical field of red copper furnace cast ingot processing, in particular to a red copper furnace drawing water pressure stabilization control system. A water tank is provided with two water inlet channels which are respectively a tap water pipeline and water supplementing pipeline; tap water in the tap water pipeline sequentially passes through a worm gear clamp typebutterfly valve and a pneumatic butterfly valve and enters the water tank; water supplementing is from an on-site water treatment cloud circulation system and is divided into two parts to flow, a Y-shaped filter and the pneumatic butterfly valve are sequentially fed into the water tank through the worm gear clamp type butterfly valve, the Y-shaped filter and the pneumatic butterfly valve, and then the water tank sequentially passes through a worm gear clamp type butterfly valve, the flexible connecting pipe and the like to form a water distribution bag of a red copper furnace, and water is supplied to the equipment; and meanwhile the worm gear clamping type butterfly valve communicate with the Y-shaped filter to supply water to the equipment. According to the red copper furnace drawing water pressure stabilization control system a variable frequency pump, an electromagnetic flowmeter and other intelligent detection elements and pipes are additionally arranged, the pressure and the flow of red copper casting water are controlled, and temperature and other technological parameters so as to achieve ideal parameter requirements. Meanwhile, the water of other furnace stations is not affected, and the casting quality of cast ingots is improved.

Description

technical field [0001] The invention relates to the technical field of copper furnace ingot processing, in particular to a copper furnace casting water stabilization control system. Background technique [0002] In the ingot processing process, the cooling rate refers to the cooling rate of the ingot, also known as the cooling intensity, which is expressed by the temperature dropped per unit time. In actual production, this variable is not easy to control, so the cooling water pressure or cooling water flow is often used as a measure of cooling speed at the production site. [0003] In direct water-cooled semi-continuous casting, as the cooling intensity increases, the crystallization speed of the ingot increases, the solute elements in the melt have no time to diffuse, the degree of supercooling increases, and the number of crystal nuclei increases, so the obtained grains are fine; at the same time, the size of the transition zone is reduced. , The density of the ingot is ...

AI Technical Summary

Problems solved by technology

If the cooling intensity is too large, the temperature gradient in the casting will increase. If the inside of the casting cannot shrink synchronously, the thermal stress value will also increase accordingly. Therefore, the crack tendency of the ingot will increase.

[0004] In the absence of accurate quantification of cooling water, it is largely necessary to rely on the experience of the master worker to judge the size of the cooling intensity, resulting in high uncontrollability and unstable quality of ingot products
