Device and method for returning circulating cooling water of continuous caster apparatus

Abstract

The invention belongs to the technical field of continuous casting in the metallurgical industry, and particularly provides a device and a method for returning circulating cooling water of a continuous caster apparatus, wherein the device comprises a continuous caster water treatment center, a cooling water pipeline and a plurality of continuous caster apparatuses; a water outlet of the continuous caster water treatment center is connected with water inlets of the plurality of continuous caster apparatuses through the cooling water pipeline; the device further comprises an apparatus cooling water return pipeline, a water accumulation pool and a cooling water return main pipe; water outlets of the plurality of continuous caster apparatuses are connected with a water inlet of the water accumulation pool through the apparatus cooling water return pipeline; a water outlet of the water accumulation pool is connected with a water inlet of the continuous caster water treatment center through the cooling water return main pipe; and a continuous caster has the problems about a high water supply pressure level and a high equipment investment. The device provided by the invention avoids the use of detection components in the cooling water return pipeline, reduces a pressure of the overall water return pipeline and lowers the cost.

Description

technical field [0001] The invention belongs to the technical field of continuous casting in the metallurgical industry, and in particular relates to a circulating cooling water return device and method for continuous casting machine equipment. Background technique [0002] In the metallurgical industry, especially in the field of continuous casting, since its equipment usually works in a high-temperature area, the equipment is affected by heat radiation, which can easily lead to a reduction in the life of the equipment. Therefore, in order to improve the service life of the equipment, the equipment in the general hot zone is designed to be cooled by water. [0003] At the same time, in order to improve the utilization rate of cooling water and reduce production costs, equipment cooling water is generally designed to be closed-circuit cooling. [0004] However, the water treatment center of the continuous casting machine is generally far away from the continuous casting mac...

AI Technical Summary

Problems solved by technology

[0004] However, the water treatment center of the continuous casting machine is generally far away from the continuous casting machine, and the production line of the continuous casting machine is relatively long. In order to meet the requirements for closed-circuit cooling of the continuous casting machine equipment, the pressure of the cooling water from the continuous casting machine water treatment should not be too low. If the system pressure is too low, the cooling water cannot form a good circulation, the cooling effect of the equipment is not good, and the purpose of cooling the equipment cannot be achieved

[0005] And sometimes in order to better detect the actual cooling condition of the equipment, some detection components are designed in the equipment cooling return water pipeline, such as pressure sensors, temperature sensors, flow meters, etc. Its equipment investment cost will be high

[0006] In order to increase the water supply pressure of the continuous casting machine, the water supply pressure level of the continuous casting machine water treatment is bound to be high, and the requirements for the corresponding valves, instruments, and pipelines will also increase, and the cost will also increase
