Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
The utility model provides an aluminium cold rolling mill hot limit portion sprays and lasts heating device, including heat exchanger 3 and hot limit oil tank 8, 3 oil inlets of heat exchanger connect into oil pipe, the oil-out is imported through hot limit oil tank 8 of oil outlet pipe connection, steam conduit is connected to the water inlet, the delivery port is through condenser tube even receiving header tank 6, collecting header tank 6 still is equipped with drain pipe 7, it is equipped with bypass pipeline to advance between oil pipe and the oil outlet pipe, all be equipped with governing valve 1 on advancing oil pipe and the oil outlet pipe, still be equipped with butterfly valve 2 on the oil outlet pipe, last stop valve 5 and the ball valve 4 of being equipped with.
In this embodiment, the regulating valve 1 is a manual butterfly valve, the butterfly valve 2 is an electromagnetic pneumatic butterfly valve, and the ball valve 4 is an electromagnetic pneumatic ball valve.
In this embodiment, the heat exchanger 3 is a plate heat exchanger, and the plate heat exchanger is connected to each pipeline through a flange.
On the basis of the original equipment capacity of resistance heating, the overall temperature in the hot-edge oil tank 8 is improved by preheating the rolling oil at the oil inlet in advance by utilizing the high temperature of steam in the heat exchanger 3, so that the heating time of the rolling oil in the hot-edge oil tank 8 is shortened, and the oil temperature of a hot edge in the rolling process is ensured; in order to ensure the control and use safety, a ball valve 4 is additionally arranged on a steam path to control steam, the steam path is in linkage control with a butterfly valve 2, the steam can be communicated only when the butterfly valve 2 is opened, the hidden danger risk caused by continuous overheating is avoided, and the device can increase the original oil inlet temperature of 38 ℃ to be higher than 90 ℃; the temperature from 105 ℃ to 92 ℃ is reduced to 92 ℃ from the end of rolling before transformation due to the control fluctuation of the temperature drop of the pipeline, the temperature of the hot edge oil after transformation can be kept at about 105 ℃ during whole-coil rolling, and the simultaneous control of the hot spraying temperature and the plate shape is effectively ensured.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
