Rolling mill unwinding energy storage

How does a rolling mill work?

In rolling mills, during the production process, intermediate steel products obtain their shape and dimension because of an array of shaping and finishing techniques. To get their shape, slabs are heated to an extreme temperature in the reheating furnace and are then rolled into shape with hot or cold rolling or in finishing mills.

What are the advantages of rolling mill automation?

Rolling mill automation can save 5%-18% indirectly, such as combustion furnace optimization control, which can effectively achieve the optimal control of air-fuel ratio, reduce incomplete combustion, improve combustion efficiency, reduce billet oxidation loss, reduce furnace unit consumption.

How much energy is needed for hot and cold rolling?

Globally, the total primary energy requirement for hot rolling was reported at 2 – 2.4 GJ/t, and global average energy needs in cold rolling are between 1 – 1.4 GJ/t. (IEA 2007). The way to harvest energy savings could be via upgrading existing furnaces. 1. Process Control in Hot Strip Mill

What is process control in hot strip mill?

1. Process Control in Hot Strip Mill To improve indirect energy savings through reduced oxygen rejects, we require improved hot strip mill process control. The main objective is to control and monitor oxygen levels to optimise the combustion rate in the furnace. It also enhances productivity and reduces downtime.
