Cast-rolling machine front box liquid level measurement and control system and measurement and control method thereof

Abstract

The invention discloses a cast-rolling machine front box liquid level measurement and control system which comprises a liquid level measurement mechanism, a furnace mouth flow adjusting mechanism and an electric cabinet. The liquid level measurement mechanism is arranged on a front box at the front end of the cast-rolling machine, and an angular displacement encoder of the liquid level measurement mechanism can collect liquid level signals in the front box; the angular displacement encoder is electrically connected with the controller input end of the electric control box arranged beside the angular displacement encoder; the bottom end of an electric push rod of the furnace mouth flow adjusting mechanism is installed through a pin shaft, the working end is connected with a rocking handle part connected with a swing arm, a cross rod part connected with the swing arm is rotatably supported above a launder through a supporting assembly, the middle of the cross rod part is connected with an adjusting plug rod through an adjusting base, and a plug at the front end of the adjusting plug rod can plug a liquid outlet hole. The electric push rod is electrically connected to the electric cabinet. According to the cast-rolling machine front box liquid level measurement and control system and the measurement and control method thereof, the liquid level of the molten aluminum in the front box can be accurately measured, meanwhile, the supply flow and closed-loop control of the molten aluminum are achieved, manpower is saved, the stability of the liquid level of the molten aluminum in the front box is guaranteed, and the cast-rolling quality is improved.

Description

technical field [0001] The invention relates to the technical field of continuous casting and rolling, in particular to a liquid level measurement and control system and a measurement and control method for a head box of a casting and rolling machine. Background technique [0002] In the production process of aluminum casting and rolling, the fluctuation of the aluminum liquid level in the front box will directly affect the quality of the rolled aluminum plate. At the same time, in order to ensure the continuity of the casting and rolling process, when the casting and rolling speed changes, the flow rate of molten aluminum also needs to change accordingly, so it is particularly important to accurately measure and control the liquid level of the head box. [0003] At present, in the casting and rolling production process, the liquid level of the aluminum liquid in the front box must be kept stable, and the way to control the liquid level in the front box is usually through ma...

Problems solved by technology

[0003] At present, in the casting and rolling production process, the liquid level of the aluminum liquid in the front box must be kept stable, and the way to control the liquid level in the front box is usually through manual observation and manual adjustment of the holding furnace eyelet plug. This manual control There is a step change in the speed of the aluminum liquid in the method, resulting in large fluctuations in the liquid level, which in turn affects the casting quality of the product

In severe cases, it can lead to plate breakage and rolling interruption, which not only reduces production efficiency, but also increases manufacturing costs, takes up labor, and the product quality is unstable
