Superstrong cooling device

Abstract

The invention discloses a superstrong cooling device which comprises a water supply pump and a plurality of branches communicated with the water supply pump. Each branch comprises an upper branch body and a lower branch body, wherein the upper branch body is provided with an upper flow adjusting valve and upper spraying water tanks, the lower branch body is provided with a lower flow adjusting valve and lower spraying water tanks, the upper spraying water tanks are opposite to the lower spraying water tanks, the upper spraying water tanks and the lower spraying water tanks are each provided with a spraying opening, the spraying openings face a belt steel passing wire, the upper branch body is provided with an upper three-way valve, the inlet of the upper three-way valve is communicated with the upper flow adjusting valve, the first outlet of the upper three-way valve is communicated with a plurality of upper spraying water tanks, a lower branch main body is provided with a lower three-way valve, the inlet of the lower three-way valve is communicated with the lower flow adjusting valve, the first outlet of the lower three-way valve is communicated with a plurality of lower spraying water tanks, and the second outlet of the upper three-way valve and the second outlet of the lower three-way valve are communicated with a slag trough through drainage pipelines. The superstrong cooling device is more flexible to adjust and more stable in running.

Description

technical field [0001] The invention relates to the technical field of cooling of hot-rolled steel strips, in particular to a super cooling device. Background technique [0002] It is an effective way to develop hot-rolled products by controlling the cooling after rolling to improve the properties of the rolled piece. At present, the cooling of rolled products such as strip steel mainly relies on laminar flow cooling devices and super cooling devices. For thick gauge pipeline steel (such as X80, etc.) and some high-strength steel types (such as DP, MP, MS, etc.), higher intensity cooling is required, and the laminar flow cooling device can no longer meet the requirements, so it is necessary to use a super cooling device for cooling . [0003] When the cooling device is working, the water supply pump is generally used to supply water to the cooling device. When the strip steel needs to be cooled, the cooling device is turned on, and when the strip steel cooling is complete...

Problems solved by technology

However, in practical applications, it is found that this has great disadvantages. The reason is that due to the high pressure of the cooling water and the large flow rate, when the pressure-maintaining pressure relief valve discharges the cooling water, it will generate a very large vibration, and the device will run Very unstable and at the same time very unfavorable for the maintenance of its mechanical equipment and electrical instrumentation equipment
