Recently, the world's first set of stainless steel drum slag processing equipment was successfully tested in Jiaxing Dongfang Special Steel, Zhejiang Province. This marks a new breakthrough in the world-leading metallurgical molten slag treatment technology developed by Baosteel. It can handle both carbon steel slag and stainless steel slag with complex performance and difficulty, and promote the circulation of China's steel industry. Economic and sustainable development have far-reaching significance.
Dongfang Special Steel is a stainless steel short-flow company in Jiaxing. Baosteel Energy Saving Co., Ltd., as a professional energy-saving and environmental protection platform of Baosteel, signed a contract with Dongfang Special Steel in September last year. Baosteel Energy Conservation provided Dongfang Special Steel with a set of stainless steel slag treatment environmental protection equipment. The annual design and processing capacity of stainless steel slag is 150,000 tons.
The drum slag treatment technology has the characteristics of cleaning, short process and convenient recycling of steel slag resources, but the technical processing is difficult. In this regard, Baosteel Energy Conservation and Baosteel Co., Ltd. cooperated with the Ministry of Science and Technology, Steelmaking Plant, Baosteel Central Research Institute and other departments to conduct technical research and experiments in Baosteel Stainless, overcoming many difficulties, optimizing and innovating the original mature carbon steel slag treatment technology. And succeeded.
In September last year, the world's first set of roller stainless steel slag processing equipment was successfully started in Dongfang Special Steel. Baosteel Energy Co., Ltd. exported the complete drum slag treatment technology and equipment manufacturing design plan to Dongfang Special Steel, and tracked the project throughout the whole process, finally achieving the success of the heat load test.
It is understood that after the roller process, the stainless steel slag can directly enter the ball mill for subsequent sorting process, achieving the separation of slag steel and the subsequent utilization of tailings, which are widely used, such as soil improver, rust blasting, floor tiles, marble, etc. .
