Automatic slag feeding robot

Abstract

The invention provides an automatic slag feeding robot comprising a slag feeding spoon, a joint arm and a control system electrically connected with the joint robot arm. The slag feeding spoon is installed on the end of the joint robot. The beneficial effects are that the slag feeding robot has small size, low price and even and smooth slag feeding; protective slag original states can be maintained; and problems of large size, high price, slag block, uneven slag feeding, protective slag smashing and dust pollution of the present automatic slag feeding technology can be solved.

Description

technical field [0001] The invention relates to the field of steelmaking and continuous casting, in particular to an automatic slag adding robot. Background technique [0002] The mold slag on the surface of the molten steel in the mold of the continuous casting machine can absorb the inclusions in the molten steel, prevent the molten steel from being oxidized in contact with air, and act as a lubricant, which is very important for improving the quality of the billet. Compared with the traditional manual adding method, the automatic adding slag to the crystallizer has the advantages of evenly adding slag, saving mold slag, and reducing the labor intensity of workers. The existing automatic slag adding device mainly has the following three conveying principles: one is to transport the mold slag from the high slag hopper to the low mold through the weight of the mold slag itself. The disadvantage is that it is only suitable for small cross-section The crystallizer is often pr...

Problems solved by technology

The existing automatic slag adding device mainly has the following three conveying principles: one is to transport the mold slag from the high slag hopper to the low mold through the weight of the mold slag itself. The disadvantage is that it is only suitable for small cross-section The crystallizer is often prone to clogging and uneven slag addition; the second is to transport the mold slag from the slag hopper to the crystallizer through the spiral slag feeding pipe, and the disadvantage is that the mold slag is easily stirred by the screw rod in the spiral slag feeding pipe The third is to transport the mold slag from the slag hopper to the crystallizer through the pneumatic conveying device. The disadvantage is that the compressed air flow in the pneumatic conveying device will easily cause dust, which will cause dust pollution and waste.

With the development of the application of intelligent robots, there have been robot-based automatic slag adding devices in recent years. It is installed on the robot arm through a spiral slag adding pipe with a servo motor and a screw to realize automatic slag adding. Its disadvantages include: In addition to crushing the mold slag, the screw slag adding pipe is too heavy, which leads to the large size and high price of the robot used.
