Technological lubricating system of hot mill steel plate continuous milling machine

Abstract

The technological lubrication system for hot rolled steel plate continuously rolling machine belongs to the field of metal rolling technology. The technological lubrication system includes an oil supplying unit, a jetting unit, a connecting pipeline, a water supplying unit and an oil-water mixing unit set between the oil supplying unit and the jetting unit, a controlled direction change unit to the output of the oil supplying unit, and an oil tank connected together. The technological lubrication system can display and record the operation state of the whole technological lubrication system and regulate the oil-water mixture ratio of the jetted liquid conveniently, and may be used in hot continuous rolling machine to raise the production efficiency.

Description

technical field [0001] The invention belongs to the field of metal rolling, and in particular relates to a process lubricating device for a steel plate hot rolling machine. Background technique [0002] In the rolling mill, the continuous casting slab or the first rolling slab is used as the raw material, after being heated by the heating furnace, it is sent to the continuous rolling mill for continuous rolling with multiple rolls, and then it can be rolled into a thin plate (also known as straight hair plate) ;After cutting the head and tail of the straight hair plate, then cutting or rewinding, it becomes a hot-rolled steel plate (coil) product; if it is trimmed and multi-pass straightened, leveled and other finishing After the line treatment, the plate is cut or recoiled to produce hot-rolled steel plate, flat hot-rolled steel coil, slitting strip and other products; if the hot-rolled finishing coil is pickled to remove scale and oiled, it will be hot Rolled pickled coil...

AI Technical Summary

Problems solved by technology

[0010] (1) The control belongs to the old-fashioned relay interlock control, which is relatively backward, and the relevant control signals of the rolling mill cannot be used. It is necessary to set up hot metal detectors and pressure sensors separately, and the failure rate is high;

[0011] (2) The scalability of the system is poor, and it can only be applied to the process lubrication system of all oil injection, not suitable for the current oil-water mixed emulsified lubricant injection system;

[0012] (3) There is no flow control, detection and display, and the working conditions of the entire process lubrication system cannot be dynamically adjusted, displayed, and recorded, which is not conducive to the operation and adjustment of process operating parameters;

[0013] (4) All signals can only be used locally, and cannot be remotely transmitted and centralized control, which does not meet the needs of the control of rolling mills with increasing automation
