【Abstract】 We use the TRIZ theory to conduct a functional and causal chain analysis for the scarp adding process and identify the key reasons for obtaining low scarp steel ratio in the production procedure. The technical conflict, physical-field analysis and physical conflict tools are used to design and improve the scrap adding method, and four novel schemes are obtained. Combined with the real-life converter steelmaking process, the optimal technical scheme is as follow: When the converter stops smelting and starts to incline and receive scraps,the scrap needs to be sent to the preheating bin of the low heat storage furnace through the conveyor for heating. The preheated scrap enters the scrap feeding hopper through the discharge port at the bottom of the preheating bin of the low heat storage furnace. After the scrap feeding hopper is moved out by the mobile flat car, it is lifted directly into the converter at the inclined receiving position by the crane.During vertical smelting in the converter, the scrap steel is lifted to the high position of the converter, and the scrap steel is quickly entered into the preheating chamber of the regenerative furnace with the chute. After preheating, the scrap steel is weighed through the chute and added into the converter in the vertical state of smelting.更多还原
