The project plans to demolish the existing main workshop area and public auxiliary works of Jiangsu Shente Iron and Steel Co., Ltd., including blast furnace system, coking power generation, steel slag yard, coal preparation plant, etc., and build a stainless steel smelting workshop, a stainless steel refining workshop, a slag cooling workshop, and a slag treatment workshop. Purchase 3 120t Kangsidi electric arc furnaces, 4 sets of 60t medium frequency furnaces, 2 100t desiliconization furnaces, 4 100t AOD furnaces, 4 100t LF refining furnaces, 2 100t VOD vacuum furnaces, 4 straight arc single flow stainless steel slab caster, supporting public works, storage and transportation projects, environmental protection projects, etc.

The project is in line with the national and provincial industrial policy and the industrial orientation of Liyang High-tech Zone, and the relevant requirements such as the implementation opinions on speeding up the transformation and upgrading of the province's chemical, iron, steel, coal and power industry (Su Banfa (2018) No. 32). The project has been evaluated and demonstrated by the Office of Jiangsu Provincial leading Group for eliminating excess capacity (Suhua Jiefa (2021) No. 12), and has been listed in the province's key project database of iron and steel (Su Fa Reform Industry Development (2021) No. 1116). The capacity replacement plan has been announced (Su Gongxin Materials (2021) 533).

The implementation of the project will have a certain adverse impact on the surrounding environment, and after the full implementation of the eco-environmental protection measures proposed in the report and this reply, the adverse ecological impact can be mitigated and controlled.
