A method for automatically dispensing process lubricating liquid in the rolling of sheet, strip and foil materials

Abstract

The invention discloses an automatic liquid preparing device and method of a technological lubrication liquid in plate and strip foil calendering. The device comprises a mechanical portion and a control portion, the mechanical portion is used for performing liquid preparing to a corresponding technological lubrication liquid during plate and strip foil calendaring, the control portion is used for real-timely controlling the liquid preparing process of the mechanical portion on the corresponding technological lubrication liquid on the basis of monitored liquid level and flow quantity of the corresponding technological lubrication liquid, and the mechanical portion and the control portion are in a signal connection. By means of the automatic liquid preparing device and method of the technological lubrication liquid in plate and strip foil calendaring, defects that production efficiencies are low, manual labor intensity is large, product surface qualities are poor and energy consumption is high in prior art can be overcome so that production efficiencies are improved, manual labor intensity is reduced, product surface qualities are improved, energy consumption is reduced, simultaneously, personnel is prevented from directly contacting petrochemical materials of emulsion, rolling oil, additives and the like, and harm of petrochemical products to the personnel is prevented.

Description

technical field [0001] The invention relates to the technical field of plate, strip and foil material production, in particular to an automatic liquid preparation method for process lubricating liquid in the rolling of plate, strip and foil material. Background technique [0002] In the field of sheet, strip and foil material production technology, on the one hand, during the hot rolling production process of sheet, strip and foil materials, hot rolling process lubricating emulsion (hot rolling process lubricating emulsion, mainly composed of water and oil in a certain proportion, commonly known as emulsion ) directly participates in the rolling production process, and mainly plays the role of cooling and lubrication in the rolling production process. The performance of the lubricating emulsion in the hot rolling process will directly affect the normal production of the industry plate (foil) strip and the shape and surface of the product. Quality, especially in the hot rolli...

Problems solved by technology

However, the above preparation and addition methods must be shut down in the cold rolling production process, which affects production efficiency. At the same time, a large number of people are required to perform manual work in the process of manual preparation and addition, and the labor intensity is high.

[0006] In summary, in the process of realizing the present invention, the inventors have found that there are at least the following defects in the prior art: (1) low production efficiency: at present, in the hot rolling production and process and cold rolling production process of plate and strip at home and abroad For the preparation and addition of hot-rolling emulsion and cold-rolling rolling oil in the actual production process on site, it is generally shut down during each heat rolling process or after the completion of rolling to manually carry out the preparation and addition of emulsion; After consumption, it is carried out by regular shutdown, and artificial preparation and addition affect the efficiency of calendering production

(2) High labor intensity: In the process of manual preparation and addition, a large number of people are required to perform manual work, and the labor intensity is high

[0007] (3) The surface quality of the product is poor: the process lubrication (emulsion) consumes a lot during the production process, and due to the volatility difference between the water and oil in the prepared emulsion under the high temperature condition of hot rolling, the emulsion before and after rolling There is a large change in the concentration, which affects the surface quality of the product. The change in the concentration of the emulsion before and after each heat rolling is large, resulting in unstable lubrication during the rolling process, resulting in surface quality problems of hot-rolled coils

[0008] (4) High energy consumption: In the production process of hot rolling and cold rolling, there are certain requirements on the process lubrication temperature. After one addition, the temperature in the process lubrication box is low, so after each manual concentrated liquid preparation, the process needs to be The lubricating oil temperature is heated to the temperature range required by the process; for example, electric heating is required after each addition, hot rolling is about 60°C, and cold rolling is about 35°C
