[0002] The pouring process is an important process in the casting production process, and the quality control of this process has a great influence on the final quality of the casting. The pouring process requires not only to ensure the pouring temperature and pouring speed, but also to timely and accurately grasp the rising of the molten metal level in the mold and the riser, so as to timely reduce the flow of molten steel, add covering agent to the riser, stop the flow of molten steel, etc. In order to accurately grasp the rising of the molten metal level in the cavity and the riser, the staff often need to stand near the sand box and observe from above the riser at a close distance or stand on a platform far away from the sand box but at a certain height to observe. In this process, if the molten steel splashes in the riser or other abnormal conditions occur during the ladle pouring process, it is very easy for the observer to be burned or fall from a height, which poses a great safety hazard.
