Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic filling of slag stoppers, in particular to an electric drive lifting structure for an automatic filling device of a slag stopper. Background Art
[0002] The converter steelmaking plant in the steel industry has adopted the slag plug placement device for more than 20 years. The corresponding process has a good effect on improving the quality of molten steel and is low-cost; however, in the preparation method of installing the slag plug on the slag plug placement device, the manual lifting and insertion method has been adopted; the automatic loading slag plug technology equipment is blank. Under the current trend of large-scale steelmaking main equipment, automation, informationization, and intelligent requirements for placement devices, and increasingly improved occupational health and safety environment requirements, it is necessary to upgrade the slag blocking process technology equipment.
[0003] The existing slag-stopping steel-making process is only equipped with a placing device for the slag-stopping plug placing process, but no corresponding equipment is configured in the slag-stopping plug installation process. Since the slag-stopping plug installation process adopts a manual lifting and insertion method, in addition to the configuration of loading labor, it is also necessary to configure operators on the placing device. Not only is the degree of automation of the whole process low, there is a lack of information data collection, but it also requires higher labor costs.
[0004] Smaller tonnage converters are equipped with slag plug placing devices. When the slag plug is manually lifted and inserted, the weight of the slag plug exceeds the ergonomic lifting condition of forearm bending and a lifting force of approximately 150N. The loading process can be barely completed by lifting the slag plug against the abdomen. With the development of large-scale converters and the increase in the diameter of the converter tapping port, the weight of the slag plug is generally more than 25kg. From the perspective of occupational health requirements, it is no longer suitable to use manual lifting and insertion operations. Utility Model Content
