It is 19.55 meters long and weighs 135 tons. It is said to be the world's largest single ductile iron casting. It was completed in the foundry workshop of Beijing No. 1 Machine Tool Plant in Gaobeidian a few days ago.

According to reports, heavy ductile iron castings are widely used in nuclear power equipment, large ships, aerospace, heavy machinery and other manufacturing industries. It is a casting product with high quality requirements and complex technology. The production of such products must have super-large production and technical equipment.

In 2000, Beiyi Casting settled in Gaobeidian from the capital, and the new environment brought new opportunities for development. After the relocation of the enterprise, the output increased exponentially through personnel reorganization and product structure adjustment. Last year, the plant bucked the trend and invested 120 million yuan to build a heavy-duty casting and super-large casting production workshop in Beiyi Foundry Base with a construction area of ​​12,000 square meters, forming the Beijing No. 1 Machine Tool (Gaobeidian) Foundry Co., Ltd. The company and Beiyi Heavy Machinery Casting Co., Ltd. dominate the "Beiyi Foundry Base", which enables the company's annual production capacity to reach 50,000 tons. In order to meet the new situation of the continuous development of domestic heavy industry, a solid foundation has been laid for the manufacture of world-class single ductile iron parts.

According to reports, the successful casting of the world’s largest single ductile iron casting not only marked a new leap in the company’s R&D and production capabilities, and set a new record in the world’s casting history. It also helped Gaobeidian actively connect with Beijing’s enterprises and promote economic development. New highlights.
