Abstract

The invention discloses a secondary cooling water purification device for a continuous casting machine. A bypass valve and a filtering pipeline are arranged on a secondary cooling water pipeline, the filtering pipeline crosses over the secondary cooling water pipeline in front and at the back of the bypass valve, a filter is arranged on the filtering pipeline, a water inlet valve is arranged on the filtering pipeline at a water inlet end of the filter, and a water outlet valve is arranged on the filtering pipeline at a water outlet end of the filter. The invention further discloses a method for operating and using the purification device. By the aid of the technical scheme, the problem of a pipeline is easily blocked when secondary cooling water flows through the pipeline is solved, the atomizing effect of a nozzle is more uniform and stable, and further continuous casting billets with high quality are obtained. Filtering processes are conveniently switched, back flushing is convenient, a filter barrel is rapidly replaced without affecting use, the quality of the cooling water is improved and stabilized, a filtering device is rapidly replaced and maintained, the quality of the secondary cooling water can be ensured under the condition of quite low investment, and the quality of the continuous casting billets is stabilized.

Description

technical field [0001] The invention belongs to the technical field of cast iron pipe production, and relates to the production equipment technology of a continuous casting machine. More specifically, the invention relates to a secondary cooling water purification device for a continuous casting machine. In addition, the present invention also relates to the operation and use method of the secondary cooling water purification device. Background technique [0002] At present, the secondary cooling water of the continuous casting machine is generally settled in the advection pool in the water pump room, degreased, and filtered by the main pipeline to remove the particulate matter in the water and reduce the clogging of the nozzle. [0003] In the actual production process, this method can only remove larger particles, and the phenomenon of nozzle clogging often occurs, which affects the quality of the slab. Contents of the invention [0004] The invention provides a seconda...
