In 2013, global steel production reached a level of 1.548 million tons. This value indicates that, in the 21st century, steel is still one of the most popular construction materials. In Poland 8.2 million tons of steel was produced in 2013. A large share of steel is used for the production of hot-rolled plates for car bodies. Steel products made in high temperature processes are used in virtually all sectors of industries. The hot-rolled plates for car bodies should comply with the highest quality requirements. In this chapter the results of research from the 3-month follow-up are presented. To assess the level of non-conformity in hot-rolled plates the Pareto-Lorenz diagram was used. The results are the basis for the improvement of the production process of hot-rolled products.
