Problems solved by technology

[0002] At present, domestic metallurgical enterprises are using sliding nozzle mechanism for flow control operation in ladle flow control technology. However, due to the special requirements of high temperature environment, some accessories are prone to quality problems such as deformation and fracture, resulting in production accidents. ;As the main pressure-bearing and pressure-applying parts of the sliding nozzle mechanism, the surface pressure rod plays a vital role in use. If the surface pressure rod has quality problems, it will directly cause the sliding nozzle mechanism to lose pressure, resulting in rigid leakage accidents

Abstract

The invention discloses a machining process of a sliding gate mechanism surface compression bar. According to the technical scheme, the machining process is characterized by comprising the following steps: (1) dividing a whole piece of round steel according to the requirements of a drawing; (2) putting the round steel into a resistance furnace for heating, forging step by step, putting into the resistance furnace for heating again, and repeating the precious process till a raw material is forged into square steel; (3) performing rough machining on the raw material by using a numerical control milling bed; (4) heating a workpiece machined in the step (3), discharging the workpiece out, then quenching, machining till the hardness HRC is about 53-58, and performing standing for next treatment; (5) finely grinding four formed surfaces of the workpiece according to the requirements of the drawing by using the numerical control milling bed; (6) processing in a gas nitriding chemical treatment mode; (7) performing anti-rusting treatment on the workpiece after the nitriding treatment.
