高炉炼铁时所产生的熔渣,必须盛入装在车架上的渣罐内,然后用火车拖运到距工厂较远的地方倾洗掉。这种渣罐,通常是用铸铁铸成。一个14立方公尺的渣罐,本身重量有二十六吨。承制该件的铸造车间,因起重、熔炼设备条件不足,存在一定的困难,为完成这一任务,对所需工具的准确、设备及造型、浇铸的工艺都加以细致的考虑。经过两个月的制作过程,第一个产品完全符合规格。
Slag produced during blast furnace ironmaking must be contained in a slag pot mounted on the frame and then towed by train to a location farther away from the factory. This slag pot, usually cast iron. A 14 cubic meter slag tank, its own weight of 26 tons. In order to accomplish this task, the casting workshop that undertakes this piece of equipment has some difficulties due to the lack of lifting and melting equipment. Careful consideration is given to the accuracy of the required tools, the equipment, the molding and the casting process. After two months of production process, the first product fully meet the specifications.
