The pouring work of large operation side mill housing 15mlong and5mwide with gross weight 387T was officially launched at 12:05 am, on September 7th, 2015, based on the previous successful pouring of four ladles. The amount of steel liquid is 677Ton. Accompanied by main leaders of Giant headquarters, special steel division and steel casting divisions, the guests from China First Heavy Industries have witnessed the whole pouring course of the biggest and heaviest steel casting in our company history.
The pouring adopts a technology of five ladles pouring together and three ladles pouring for risers, which poses a great challenge to the whole production organization.
On September 6th, vice-president of headquarters Mr. Sun held a meeting to demonstrate the pouring of the mill housing (operation side), make a strong emphasis on the safe operation and ensuring a guaranteed scheme, and further refine the operation scheme. The meeting also underscored assigning the responsibility to the relevant people and conveying all the information to every operator, to pave the way for a successful pouring operation. The attendance includes the relevant personnel of technology center and production department of company, steel casting division and special steel division.
The first ladle of steel liquid was lifted at 12:05 am, and then the rest of five ladles after LF refining were lifted one after another. Every staff arrived at appointed location promptly, and was better prepared for the pouring with concentration. The first two stationary ladles were fixed on appointed location in ten minutes according to the exercise location of ladle the day before. Another three crane ladles were in their places rapidly. With the order of the chief dispatcher in charge of the pouring course, the stationary ladles started the pouring firstly, and then the ladle holes of other three crane ladles was open by means of burning. The steel liquid flowed out through ten ladle hole within a short time, and the pouring proceeded smoothly. An hour later, the risers were poured again successfully for continuous three times, meaning that the pouring of the operation side housing was accomplished!
The pouring of three crane ladles and two stationary ladles demonstrates the operation ability and coordinate ability of every production department, and lays a strong foundation for the next pouring with two crane ladles and three stationary ladles, and even six-ladles pouring at the same time. The pouring practice also proves that our management and production quality have made a great progress and reach a new stage again.The success of five-ladles pouring inspires the confidence of Giant people, and foretells the takeoff of Giant and an aglitter tomorrow!
