Embodiment Construction
[0010] A process for treating oily sludge from steel rolling by utilizing the residual heat of steel slag, the steps are as follows: 1. Spread and load steel slag exceeding one-third of the volume of the slag pool in the hot stuffy slag pool, and control the surface temperature of the steel slag at above 500°C; 2. 1. Pull and transport the oil sludge produced by steel rolling to the hot stuffy slag field, pour the oil sludge into the hot stuffy slag pool, and spread it evenly; 3. Continue to feed the slag into the slag pool, and pour high-temperature liquid steel slag on the evenly spread rolled steel For the upper part of the oil sludge, follow the normal hot stuffy slag process after 30 minutes; 4. After the hot stuffy slag process is over, select the iron in it for use according to the normal magnetic separation process of the steel slag iron selection process.
