These products have been applied successfully in these steer plants. They are the third steel-making factory of Wuxi steel plant, the second steel-making factory of Xixing steel plant, Fuzhou steel plant and Dayei steel plant. The lid of electric cooker and LF kiln’s life span is two times longer than former small kiln’s lid, and the time that is needed for replacing small kiln’s lid is shortened by 3/4. The usage of the products made the operation easy and consumes less electricity, improves the environment and order of production. It creates nicer benefits of economy and society.
