Description

Technical Field

[0001] The invention relates to the technical field of design and application of a slag scraper truck, in particular to a slag scraper device of an electric slag scraper truck. Background Art

[0002] Aluminum casting slag removal vehicles play the role of removing sediments at the bottom of liquid metal and slag on the surface in key equipment such as smelting furnaces, holding furnaces, and mixing furnaces in many medium and large aluminum plants, with the purpose of improving the quality of aluminum ingots. The slag removal operation of domestic aluminum smelting furnaces has traditionally relied on manual operation or modified forklift-type slag removal tools. However, this operation method is time-consuming, and the slag removal effect is not satisfactory. The slag removal tools are prone to deformation and damage, resulting in frequent replacement, which increases the cost of use. During the slag removal process, the furnace door is open for a long time, resulting in a large amount of heat loss, and it will also cause aluminum material burning, thus affecting the quality of the smelted metal. Therefore, in order to solve these problems, slag removal vehicles came into being. Slag removal vehicles are mainly composed of a walking mechanism and a slag removal device mounted thereon. The slag removal device is usually composed of a telescopic arm and a lifting mechanism to drive the slag removal head to complete the slag removal task. However, most slag removal vehicles on the market are powered by an oil-driven system, but their operating costs are high, and their mechanical structure design is not compact enough, their dead weight is large, and there are unreasonable configurations.
