STATE OF THE DIRECT REDUCTION AND REDUCTION

3. Direct Reduction Processes Direct reduction is defined as a process of producing solid iron product out of small-grain ore, lump ore or pallets, applying natural gas or coal-based reducing agents at relatively low temperatures i.e. at around 1000OC. There are two different types of direct reduction

What are Reduction Gears? What is Gear Reduction? Bright

Reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. A reduction gear assembly consists of a set of rotating gears connected to a wheel work. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, wherein the motion or torque is changed.
