Technical Field

The invention relates to a pipe mill, in particular to a graphite core rod water blowing device of the pipe mill.

Background

At present, in the production process of a mandrel cooling water ring of a mandrel trolley of a tube rolling mill, the cooling water ring cools a mandrel after tube rolling, the mandrel is cooled by water and then enters a graphite spraying ring to be sprayed with graphite, the inner surface quality of the rolled tube is improved, but the mandrel cannot be completely dried out due to the high-pressure water cooling, water enters graphite spraying equipment, the graphite spraying quality is poor, the water enters a graphite recovery tank, and the graphite solubility is reduced.

Disclosure of Invention

The invention aims to provide a water blowing device for a graphite core rod of a pipe mill, which has the characteristics of improving the spraying quality of graphite and reducing the using amount of graphite, and solves the problems of graphite spraying of the graphite core rod of the pipe mill in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a tube mill graphite plug blows water installation, its includes tube mill plug, the front and back section of tube mill plug is provided with cooling water ring and graphite spraying ring respectively, cooling water ring inserts cooling water system, graphite spraying ring inserts graphite spraying system, wherein, be provided with one at least high pressure ring of blowing between cooling water ring and the graphite spraying ring, a plurality of wind gap has been seted up on the ring of blowing, high pressure ring of blowing inserts high pressure air drying system.

In particular, the high-pressure water blowing rings are arranged in one pass.

In particular, the high-pressure air drying system comprises a compressed air pump which is communicated with the high-pressure water blowing ring through a pipeline.

In particular, the tuyeres are evenly distributed on the high-pressure water blowing ring.

Compared with the prior art, the graphite core rod water blowing device for the tube rolling mill has the advantages that the high-pressure water blowing ring is additionally arranged between the cooling water ring and the graphite spraying ring, and water on the surface of the core rod is dried before the core rod enters the graphite spraying, so that the water entrainment is effectively reduced, the graphite spraying quality is improved, the quality of the inner surface of a steel tube is improved, and the use amount of graphite is reduced.

Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a graphite core rod water blowing device of a pipe mill according to embodiment 1 of the present invention; fig. 2 is a schematic structural diagram of a high-pressure air drying system of a pipe mill graphite core rod water blowing device according to embodiment 1 of the present invention.

In this embodiment, a pipe mill graphite plug blows water installation includes pipe mill plug 1, pipe mill plug 1's front and back section is provided with twice cooling water ring 2 and three graphite spraying ring 3 respectively, cooling water ring 2 inserts cooling water system, graphite spraying ring 3 inserts graphite spraying system, be provided with one high pressure water ring 4 between cooling water ring 2 and the graphite spraying ring 3, a plurality of wind gaps 5 have evenly been seted up on the high pressure water ring 4, just high pressure water ring 4 passes through pipeline 6 and connects compressed air pump 7, compressed air pump 7 sends for high pressure water ring 4 high pressure wind through the pipeline behind the compressed air.

When the device works, a pipe rolling mill mandrel 1 is firstly cooled after being rolled through a cooling water ring 2, then the pipe rolling mill mandrel 1 passes through a high-pressure water blowing ring 4, the water on the surface of the pipe rolling mill mandrel 1 is dried through the high-pressure water blowing ring 4 so as to reduce the water brought into a graphite spraying process as much as possible, and finally the pipe rolling mill mandrel 1 passes through a graphite spraying ring 3 to perform graphite spraying on the surface of the pipe rolling mill mandrel.

The graphite core rod water blowing device of the pipe mill can effectively reduce the process of spraying graphite by taking water into the graphite, improves the spraying quality of the graphite, improves the inner surface quality of a steel pipe, and reduces the use amount of the graphite. Reduce the defects of the inner surface, improve the quality of the inner surface product and reduce the consumption of auxiliary materials, thereby playing the role of cost reduction and efficiency improvement.
