A few days ago, I learned that a grooving knife row structure independently developed by Fangda Special Steel, an improved furnace top feed tank receiving device, and an improved synchronous moving device for a steel ejector were granted patent rights by the State Intellectual Property Office, and a utility model patent certificate was issued. By developing a grooving cutter that can be used on an ordinary lathe, it is suitable for grooving knives of different specifications to process various grooves on the short shaft, and the tool can be fed once to ensure product quality. An improved furnace top material tank receiving device adds a guide hopper to the receiving hopper, which not only prolongs the service life of the unloading port, but also quickly replaces the guide hopper to ensure the stability and reasonable structure of the unloading center point, effectively solves the problems of equipment damage caused by large wear at the discharge port and damage to downstream equipment due to changes in material flow direction, and improves production efficiency. The improved synchronous traversing device of the steel ejector effectively solves the problems of the top rod deviation and the short life of the clip roller bearing. (Securities Times)
