Device for automatically controlling semicontinuous casting liquid level of aluminum and aluminum alloy

Abstract

The invention relates to a device for automatically controlling semicontinuous casting liquid level of aluminum and aluminum alloy, comprising a smelter control part, a sluice control part and a casting platform control part; the smelter control part comprises a hydraulic pump and a hydraulic cylinder, one side of the smelter is supported on a base through a rotary shaft, the other side of the smelter is hinged with a piston rod of the hydraulic cylinder, the cylinder barrel of the hydraulic cylinder is hinged on the base, the hydraulic cylinder is accessed into the hydraulic pump through pipelines via an electromagnetic valve, and the hydraulic pump is accessed into an oil tank; the sluice control part comprises an air cylinder and a sluice baffle, a position finder and the sluice baffle are arranged at the entrance of the casting platform, the piston rod of the air cylinder is connected with the sluice baffle in a driving manner, and the air cylinder is accessed into an air pressure source through pipelines via an electromagnetic valve; the casting platform control part comprises a DC motor and a core plug; the position finder is arranged in a crystallizer provided with the core plug, and the DC motor is connected with the core plug in a driving manner. The device can ensure accurate control on the whole semicontinuous casting process and improves cast ingot quality.

Description

technical field [0001] The invention relates to an automatic liquid level control device, in particular to an automatic liquid level control device for aluminum and aluminum alloy semi-continuous casting. Background technique [0002] With the development of the aluminum processing industry, aluminum processing enterprises and research institutions are committed to improving the surface quality of ingots, making the surface of ingots as smooth as possible, reducing or eliminating surface defects such as coarse grain layers and segregation tumors, and reducing the thickness of ingots. Poor, bottom warping and swelling etc. Make the ingot face milling or no milling as much as possible before hot rolling or extrusion, so as to improve the success rate. The application of liquid level automatic control equipment can effectively improve the quality of ingots and become a key device in the semi-continuous casting process. [0003] The Chinese patent No. 200420074670.X discloses ...
