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 a

Example Embodiment

[0024] Example 1:

[0025] like Figure 1-2 As shown, a continuous casting machine equipment circulating cooling water return device includes a continuous casting machine water treatment center 1, a cooling water pipeline 2 and a plurality of continuous casting machine equipment 3, and the water outlet of the continuous casting machine water treatment center 1 is cooled The water pipeline 2 is connected to the water inlet of multiple continuous casting machine equipment 3, and also includes equipment cooling return water pipeline 11, pond 12, and cooling return water main pipe 10, and the water outlets of multiple continuous casting machine equipment 3 pass through the equipment cooling return water pipeline 11 is connected to the water inlet of the accumulated water pool 12, and the water outlet of the accumulated water pool 12 is connected to the water inlet of the continuous casting machine water treatment center 1 through the cooling return water main pipe 10.

Example Embodiment

[0028] Example 2:

[0029] On the basis of Embodiment 1, a lifting device 14 is further included, and the water outlet of the accumulated water pool 12 is connected to the inlet port of the cooling return water main pipe 10 through the lifting device 14 .

[0030] The existing conventional technology is to set a flow meter in the cooling water return pipeline of the equipment, and judge the cooling condition of the equipment by detecting whether there is flow in the pipeline; in fact, the cooling condition of the equipment is determined by whether there is cooling return water and the size of the return water. It is judged that in order to achieve this purpose, flow meters and valves are designed on the return water pipeline. Greatly increased the investment of continuous casting machine. In actual use, the cooling condition of the equipment does not require very high cooling water. As long as the pipeline is not blocked and the cooling water volume is not abnormally large, i...

Example Embodiment

[0036] Embodiment 3:

[0037] On the basis of Example 2, a continuous casting machine equipment circulating cooling water return method includes the following steps: the continuous casting machine water treatment center 1 supplies cooling water to the continuous casting machine equipment 3, and the cooling water passes through the continuous casting machine equipment 3 After that, it enters the accumulated water tank 12 for storage, and the lifting device 14 lifts the water in the accumulated water tank 12 to the casting machine water treatment center 1 for processing.

[0038] In the present invention, since the return water first enters the accumulated water pool 12 next to the continuous casting machine equipment 3, the accumulated water pool 12 is conducive to the precipitation and cooling of the backwater, and only the lifting device 14 is required to lift and suppress the water in the accumulated water pool 12 to The water treatment center 1 of the continuous casting mac...

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...
