On July 14th, as the firecrackers started to crack, another significant product-600t Huizhou Nuclear Half-speed Rotor was slowly rolled out from the steelworks plant, which was the 24th steel ingot for nuclear half-speed rotor and the 5th 600t steel ingot. The success of this hot charge marked that Erzhong had passed another major test and delivered a good answer to her client.

It is a daunting task to manufacture 600t huge steel ingot, which not only tests extreme ability of supporting equipment and technical strength of workers, but also challenges the coordination of multiple systems.  

After taking on this task, the team of technical backbones in the casting and forging plant of Erzhong made a comprehensive summary of difficult and key points in the manufacturing of huge steel ingot by drawing from its success in manufacturing experience and fully demonstrating rationality of parameters in its carefully designed process. From selection of raw materials, production organization and arrangement to control of every package of molten steel and every package of chemical composition, every detail of the process had been repeatedly deduced to finally determine the optimal technical program.

Elaborate technical preparation is the basis of smooth production, while the perfect control of process detail is the guarantee of quality. With full preparation and 23 hours of continuous production, great success was made in the combined casting of the four packages of the 600t Huizhou half-speed rotation shaft. The cracking of the firecrackers not only marked the completion of this casting but also sounded the call to more efforts of Erzhong people in the next task.
