In the later stage of steel tapping of converter steelmaking, in order to avoid quality accidents caused by over-standard rephosphorization of molten steel due to the fact that converter slag flows into a molten steel tank, slag blocking balls are generally thrown into the converter to block the converter slag. The slag stopping ball is generally delivered by a slag stopping ball vehicle, and the concrete operation steps are as follows: firstly, the slag blocking ball vehicle is moved to the position near the converter, then a slag blocking rod in front of the slag blocking ball vehicle is used for clamping a steel bar on the slag blocking ball, and finally the slag blocking rod is controlled to put the slag blocking ball into a specified position in the converter. The existing slag stopping ball vehicle is characterized in that an operator continuously reminds passing personnel to avoid the slag stopping ball vehicle to complete reset action; due to slight negligence, the slag stopping ball car sweeps away from the side of the personnel when backing, which often endangers the personnel or causes injury. The working environment of converter steelmaking is severe, and devices which are installed more precisely can be damaged quickly. In the prior art, a detection device is not installed, and the automatic returning and returning of the slag stopping ball car cannot be realized.
