Understanding Yield Loss in Iron and Steelmaking

A yield loss arises in any parts of the iron and steel making process, when for a particular step, the weight of the steel product made is less than the input of steel that is used. In a cold rolling mill for example, if the input - often called a charge weight - is 100 tonnes of hot rolled coil, and the output is 95 tonnes of cold-rolled steel
