It is understood that the current domestic wind energy generator set does not have a 1500 kW power hub casting, and the wind energy generator set can only operate at a low temperature of minus 20 degrees. After careful research and repeated tests, Dongqi Casting finally successfully casts the wind turbine generator hub under the low temperature minus 20 degrees.
With the vigorous promotion of the product structure adjustment and upgrading of the "four electric powers" product by Dongfang Steam Turbine Works, Dongqi Casting has increased the intensity of continuous development of new products. The casting of wind turbine generator sets with "new, difficult and urgent" is included in the schedule of this year's production focus. Due to the long preparation period of production, single-piece casting can not meet the requirements of just-in-time production. They boldly innovated in the production mode, and formulated a production plan for the wind turbine generator wheel hub twice a night, and carried out detailed production planning. .
For the first time, Dongqi Foundry Co., Ltd. successfully poured new products into the foundry industry, mastered new technologies, adapted to new situations, broke production routines, and wrote a new page on the history of casting in a new way of production organization.
China Eastern Electric Group Corporation's core enterprise Dongfang Steam Turbine Works Foundry Co., Ltd. (referred to as Dongqi Casting) successfully completed the first 1500 kW wind energy generator set hub, which refreshed the record of domestic large-scale high-end ductile iron castings.
