The manufacture of steel is a hot topic

The manufacture of steel is a hot topicThe most well-known of these is the Linz-Donawitz process (or LD process), also known as the basic oxygen steel making process. Liquid pig iron and scrap metal are fed into the LD converter, and flux for making slag is added. Oxygen is blown into the cast via a lance.

Open hearth process is a slow process and easy to control. We can minimize the slag due to the low speed and high efficiency of the process. The process is controlled and all the carbon need not be burned, unlike Bessemer process, hence being able to stop the process when required carbon contents are achieved.
