Find out what the Q-BOP process is for steelmaking.
The Q-BOP process for steelmaking is a variation of the basic oxygen process (BOP), which involves blowing high-purity oxygen through a bath of molten pig iron. This is called the Q-BOP process, used in the production of low-alloy steel, which is defined as steel that has no more than 5 percent total combined alloying elements.
It has mainly a surface hardness. The depth of hardness depends on alloy content. There are five types of processes currently employed in the production of low-alloy steels: oxygen top-blowing, known as LD (Linz-Donawitz) process, BOF (basic oxygen furnace), or BOP; oxygen and lime bottom blowing, known as OBM or Q-BOP; top and bottom mixed blowing; open-hearth furnace; and electric-arc furnace.
