Description

Technical Field

[0001] The utility model relates to the technical field of steel rolling equipment, in particular to a multi-channel rotary controlled cooling water tank for high-speed wire rod rolling. Background Art

[0002] High-speed wire rods all adopt the controlled rolling and controlled cooling process. During the rolling process, several water tanks need to be installed along the rolling line to control the temperature of the rolled pieces. In order to improve the cooling capacity and temperature uniformity of the water tanks, coolers, blowers and air pipes with different inner diameters are required for rolled pieces with different specifications. For most high-speed wire rod rolling production lines, the specifications of the rolled pieces span a large range, and often 2 to 4 water tank channels with different inner diameters are required. They need to be replaced according to the specifications, and the replacement workload is very large.

[0003] For example, the utility patent application number: 201520729923.0, "A fully automatic multifunctional double-sided controlled cooling water tank for high-speed wire rods", includes a box body and a hydraulic cylinder device for controlling the lateral movement of the box body, and two sets of main cooling devices are arranged horizontally at intervals in the box body; a pulley group is horizontally installed at the lower end of the box body, and a hydraulic cylinder device for controlling the lateral movement of the box body is arranged below the pulley group. The hydraulic cylinder device for controlling the lateral movement of the box body mainly includes a slide, a limit block, and a hydraulic cylinder assembly.

[0043] The cooling module 2 includes a rotating shaft 208 rotatably mounted in the housing 101 and an inlet pipe group, a plurality of coolers 204, a plurality of purges 205, and an outlet pipe group 206 sequentially arranged on the rotating shaft 208 starting from one side of the inlet duct 102. The inlet pipe group, the cooler 204, and the outlet pipe group 206 are all fixedly mounted on the rotating shaft 208 through a nozzle fixing frame 201 and an auxiliary fixing frame 202. The purge 205 is fixedly mounted on the rotating shaft 208 through a nozzle fixing frame 201. The inlet pipe group, the plurality of coolers 204, the plurality of purges 205, and the outlet pipe group 206 are respectively provided with a plurality of inlet air-through pipes 203, cooling pipes, purge pipes, and outlet air-through pipes of different inner diameters. , the inlet air-through pipes 203, the cooling pipes, the purge pipes, and the outlet air-through pipes of multiple different inner diameters are detachably mounted on the nozzle fixing frame 201 and the auxiliary fixing frame 202 around the rotating shaft 208 in sequence, and the pipes with the same inner diameter are arranged in a one-to-one correspondence. Each of the cooling pipes and the purge pipes on the multiple coolers 204 and the purge 205 is provided with a water inlet or an air inlet. The water inlets and air inlets at the tops of the multiple coolers 204 and the purge 205 are respectively connected to the piping system on the protective cover 3. The piping system is used to provide cooling water and compressed gas to the coolers 204 and the purge 205, thereby cooling and drying the rolled pieces inside the coolers 204 and the purge 205;

[0044] One end of the rotating shaft 208 is connected to a driving mechanism, and the driving mechanism is installed on the outer wall of the box body 101 on a side close to the inlet duct 102 .

[0045] The inlet air-through pipe 203 and the outlet air-through pipe on the inlet pipe group or the outlet pipe group 206 can be detachably installed between the nozzle fixing frame 201 and the auxiliary fixing frame 202, and are located at both ends of the rotating shaft 208.

The purge pipe is installed between each nozzle fixing frame 201. A flat gasket sealing ring 211 is provided between the nozzle fixing frame 201 and the cooling pipe or the purge pipe.

[0046] When in use, the rolled piece first enters from the inlet conduit 102 of the box 101, then passes through the inlet pipe group, multiple coolers 204, multiple purge devices 205, and the outlet pipe group 206 in sequence, and is finally transported from the outlet conduit 105 to the next process. When the rolled piece enters the cooler 204, the piping system on the protective cover 3 transports the cooling water treated by the turbid circulating water treatment system to the cooling pipe of the cooler 204 to cool the rolled piece passing through. When the rolled piece cools, the cooling water flowing out of the cooler 204 and the iron oxide scale falling off the rolled piece will eventually pass through the drain pipe 111. The dried rolled piece is then blown dry by the blower 205 and output to the cooling box 1 under the action of the guide wheel in the outlet pipe of the outlet pipe group 206 to enter the next process.

When the rotating shaft 208 rotates, the inlet pipe group, multiple coolers 204, multiple blowers 205 and outlet pipe group 206 on it are driven to rotate simultaneously until The pipe with the required inner diameter is rotated to align with the inlet duct 102 and the outlet duct 105, the driving mechanism is closed, and the inlet pipe group, multiple coolers 204, multiple purges 205, and multiple cooling channels on the outlet pipe group 206 are installed around the rotating shaft 208, which can make full use of the internal space of the equipment, make the cooperation between the various components more compact, thereby improving the overall efficiency and performance of the equipment, and making the overall shape of the equipment smaller and occupying a smaller area, thereby reducing the cost of production and transportation. Furthermore, by placing the cooler 204 close to the outlet pipe group 20 A blower 205 is provided at one end of 6, and each cooler 204 is connected to the pipeline system at the same time. After the cooling water cools and cools the rolled piece, the residual moisture in the cooling pipe of the cooler 204 and the water vapor on the surface of the rolled piece can be quickly blown dry. This can not only improve the service life of the cooler 204, but also prevent the rolled piece from bringing out the cooling water in the subsequent production process, thereby avoiding contamination of the production line and equipment, and avoiding the residual water vapor from adversely affecting the surface quality of the rolled piece. Blowing off the water vapor helps to maintain the surface quality of the rolled piece and reduce defects caused by cooling water.

[0049] The control component includes an electric push rod 403, the telescopic end of the electric push rod 403 is connected to the driving arm 310 through a pin shaft 1 309, and a plurality of bases 4 are provided at the bottom of the box body 101. A bottom plate 110 is fixedly installed between the base 4 and the box body 101. A support seat 401 is provided on one side of the base 4 near the bottom center of the box body 101.

[0050] The piping system includes a cooling water inlet pipe 306, a cooling air inlet pipe 307, and a purge air inlet pipe 311. The cooling water inlet pipe 306 is distributed in an array at the top of the cover body 301 and is arranged one-to-one with the water inlets on the multiple coolers 204. The cooling air inlet pipe 307 is connected to the cooling water inlet pipe 306, and the purge air inlet pipe 311 is installed at a position on the cover body 301 corresponding to the air inlet on the purge 205. The ends of the cooling water pipe and the purge air inlet pipe 311 connected to the cover body 301 are both connected to an inner sleeve 314.

The cooling water inlet pipe 306 provided on the cover 301 corresponds to each cooler 204 one by one, so as to facilitate the injection of cooling water into each cooler 204 to cool the rolled piece. After the rolled piece is treated with cooling water, the compressed gas is transported to the cooling pipe of the cooler 204 through the cooling air inlet pipe 307 connected to the cooling water inlet pipe 306, thereby cooling the rolled piece. The internal water vapor is blown dry to effectively remove residual moisture and reduce the risk of rust, thereby extending the service life of the cooler 204. Blowing dry the cooling pipe pipeline helps to remove impurities and sediments in the pipeline and keep the pipeline unobstructed. By blowing dry the pipeline, it can be ensured that the cooling water can flow quickly and evenly through the entire cooling system when used next time, achieving the best cooling effect. At the same time, before the rolled piece enters the outlet pipe group 206, the compressed gas is transported to the blower 205 through the purge inlet pipe 311, so as to quickly dry the moisture on the surface of the rolled piece and avoid residual moisture on the surface of the rolled piece, which affects subsequent production. In this embodiment, a guide plate 302 is provided around the bottom of the cover body 301. The guide plate 302 can play a positioning and guiding role when the cover body 301 is buckled with the box body 101, and a plurality of observation ports 303 are provided on the top side of the cover body 301, so that the operating status inside the box body 101 can be observed at any time, so as to quickly check the abnormal equipment status and production status.
