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] To sum up, in the process of realizing the present invention, the inventor found that there are at least the following defects in the prior art: (1) Low production efficiency: At present, in the production and process of hot rolling and cold rolling 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 carry out manual work, and the labor intensity is high
[0007] (3) The surface quality of the product is poor: process lubrication (emulsion) consumes a lot during the production process, and due to the difference in volatility of water and oil in the prepared emulsion under hot rolling high temperature conditions, 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
