Shandong Senya Metal Products Co., Ltd. is a manufacturer specializing in the production of oxygen lance pipes, coated oxygen lance pipes, refractory oxygen lance pipes, and small bore thick-walled oxygen lance pipes. The company's products are widely used, primarily for conveying oxygen or other gases during metal smelting in electric arc furnaces, cleaning up slag in converters to achieve decarbonization. Steel mills typically use small bore straight seam welded pipes, with some also opting for seamless steel pipes. Special treatment of the ends of the焊接 steel pipes (butt joints and threaded connections) effectively addresses the issue of residual pipe affecting the oxygen lance, making it easier for customers to use and improving material utilization, extending the lifespan of materials, and reducing labor intensity. The single-consumption of oxygen lance pipes has decreased from about 6Kg/t of the original oxygen lance pipes to below 2Kg/t, which not only enhances the operating rate of electric furnaces, shortens smelting time, but also reduces cost and expenses.
