Привет всем!
Помогите, пожалуйста, перевести: DRI, HBI - название сырьевых материалов, применяемых в сталеварении.

Thanks in advance.

Direct Reduced Iron or sponge iron as it is often referred to, is the substitute for melting scrap in the steel making process. It is a manufactured high ferrous content charge material for iron and steel making. It is produced in lump or pellet form sized typically at 4 by 40 mm. It also comes in compacted and briquette form known as Hot Briquetted Iron (HBI), which is made by hot compacting DRI at temperatures over 650°C into a pillow - shaped briquette measuring 110x50x30mm.
