How Rolling Mills Work in Steelmaking. Rolling mills work by using multiple rollers to manipulate the physical properties of sheet metal. In steelmaking, they offer a uniform thickness and consistency for the steel sheet metal with which they are used. Rolling mills contain rollers that squeeze and compress sheet metal as it passes through them.
Following are the 6 different types of rolling mills used in many industries: Two high rolling mills. Three high rolling mills. Four high rolling mills. Cluster rolling mills. Planetary rolling mills. Tendem or Continuous mills. 1.
The advantages of Rolling process are as follows. By rolling, uniform dimensions of the components can be obtained. It uses the same tool in the sense, the same rollers are responsible for the production of various …

This process gives steel a higher strength-to-weight ratio than can be made on a hot mill. A modern five-stand tandem cold mill may receive a sheet about 1/10 inch (0.25 cm) thick and 3/4 of a mile (1.2 km) long; 2 minutes later that sheet will have been rolled to 0.03 inch (75 mm) thick and be more than 2 miles (3.2 km) long.
The twentieth century was the century in which metallurgy evolved from a handicraft to an engineering science. In the last thirty years of that century and, in particular, the twenty-first century, the world's steel industry, including the Chinese steel industry, are facing with new challenges and opportunities for development.

A Steel Plate Rolling Mill (SPM) is a milling machine that uses rollers to press hot slab inputs to produce ferrous or non-ferrous metal plates. To produce high-quality steel plates, it is important to precisely detect and sense values of manufacturing factors including plate thickness and roll force in each rolling pass. For example, the estimation or …
