Metallurgical industr冶金行业

在冶金行业，公司起步于宝钢三期建设(1993年-1998年)，以转化设计、合作制造等方式吸收消化先进除尘技术后，先后研制了具有完全自主知识产权的LFSF型大型分室反吹风袋式除尘器、LCMD型大型长袋脉冲除尘器等国家级新产品，并迅速在钢铁行业得到了推广应用，目前除尘器产品已遍及原料、焦化、烧结球团、炼铁、炼钢以及轧钢等众多生产环节，并出口至日本、韩国、印度、巴西、墨西哥、菲律宾等国家。

In the metallurgical industry, the company started with the construction of Baosteel Phase Ill (1993-1998). After absorbing and digesting advanced dust removal technology through transformation design, cooperative manufacturing, and other methods, it has successively developed national level new products with completely independent intellectual property rights, such as LFSF large chamber back blowing bag filter, LCMD pulse long bag filter, etc., which have been quickly promoted and applied in the steel industry. Currently, dust collector products have covered many production processes such as raw materials, coking, sintering pellets, iron making, steelmaking, and steel rolling, and have been exported to countries such as Japan, South Korea, India, Brazil, Mexico, and the Philippines.
