After 10 days of hard work, Shaanxi Diesel Engine Heavy Industry Co., LTD., recently successfully poured out the heavy casting product -- AV80 casing. It is reported that the shell weighs more than 40 tons. It is the ultra-large tonnage casting currently produced by Shaanchai Heavy Industry Co., LTD. It is also the ultra-large tonnage casting cast in the newly put into production casting workshop after the company adjusted the casting capacity.
The case of AV80 is large in volume and weight, and the sand box, iron press and casting groove required in the casting process are all special tools. For this reason, Shaanchai Heavy Industry also designed and welded 2 pieces of 4-meter-long casting groove, 1 piece of modeling ring box, 16 pairs of lock box ears, 8 pieces of large lock box special bolts and other tools while borrowing the tooling, which effectively guaranteed the product quality.
As the shell structure and production process of AV80 are quite different from the products previously cast by Shaanchai Heavy Industry Co., LTD., during the production process of AV80, the company's technicians drew lines in strict accordance with the requirements of the drawings when positioning the sand cores, which met the requirements of casting size. When developing the production process, the company adopts the "double insurance" scheme of pressing iron and locking box bolts at the same time to eliminate the phenomenon of castings scrap; The difficulty of pouring was successfully solved by using self-made pouring groove to draw molten iron. In addition, the company also uses the return charge to melt molten iron for production, which greatly reduces production costs. The smooth pouring of this large casing has accumulated experience for Shaanchai heavy castings production in the future, and laid a solid foundation for the company to expand new markets and enter the market of super large castings.
