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.

Embodiment 1

[0037] Embodiment 1, a joint robot automatic slag adding device is used for automatic slag adding of a first-class large-section crystallizer, such as Figure 2-Figure 3 As shown, the joint manipulator 1 is installed on the mobile trolley 10. When not working, the mobile trolley and the joint manipulator 1 on it can be evacuated to a storage place away from the crystallizer; 1. Place it on the casting platform facing the center of nozzle 4 and close to the mold cover for automatic slag addition. Optionally, a translation mechanism of the lead screw and nut pair can also be installed on the mobile trolley, and the joint robot is installed on the translation mechanism. When working, the joint robot moves in a direction parallel to the width of the crystallizer driven by the translation mechanism.

[0038]It should be noted that the moving trolley 10 is not limited to a trolley that is manually driven to move, and may be driven by an electric motor or the like to move. The slag ...

Embodiment 2

[0039] Embodiment 2, a joint robot automatic slag adding device is used for the automatic slag adding of crystallizers 31, 32 with small and medium sections (such as billets, rectangular billets, and round billets), such as Figure 4-5 Shown, it is the application of the automatic slag adding device of the two-stream rectangular billet crystallizer. The difference between this embodiment and the first embodiment lies in the moving path of the slag adding spoon 18 and the timing of pouring mold slag during the moving process. In this embodiment, the set path means that the slag adding spoon 18 goes from point A (left slag basin 21) → point B1 (upper left part of the mouth of crystallizer 31) → point B2 (upper right part of mouth of crystallizer 31) → D Point (right slag basin 22)→C1 point (upper right part of crystallizer 32 mouth)→C2 point (left upper part of crystallizer 32 mouth)→A point, so reciprocating. Among them, between point A and B1, between point B2 and point D, be...

Abstract

The invention provides an automatic casting powder feeding device and method of an articulated robot. The device comprises casting powder pots used for storing casting powder, an articulated robot which mainly comprises an articulated robot arm and a control system for controlling the articulated robot arm, and a casting powder feeding scoop mounted at the end of the articulated robot arm. The method comprises the following steps: the casting powder feeding scoop is driven by the articulated robot to scoop the casting powder, move according to a set path, pour the casting powder out of the casting powder feeding scoop into crystallizers, and re-scoop the casting powder, and the operation is repeated in this way. The automatic casting powder feeding device disclosed by the invention has the beneficial effects of being small in size, low in price, smooth and uniform in feeding of the casting powder, capable of maintaining the original form of the casting powder, environmental-friendly and the like, and solves the problems of a conventional automatic casting powder feeding device being large in size, high in price, subjected to clogging of the casting powder, nonuniform in feeding of the casting powder, subjected to crushing of the casting powder, liable to generate dust pollution and the like.

Description

technical field [0001] The invention relates to the field of steelmaking and continuous casting, in particular to an automatic slag adding device and method for a joint 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. The traditional method of adding mold slag (referred to as slag addition) to the crystallizer is the manual adding method. Compared with the traditional manual manual adding method, the automatic slag addition to the mold has the advantages of uniform slag addition, saving mold slag, and reducing 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 th...
