How is rolled steel heated
WebSteel heated above the point of recrystallization and forced between two rollers to achieve a specific length and thickness is known as hot rolled steel. The steel, as a result, can be more pliable and flexible. For hot-rolled steel sheets, slitting, shearing, blanking, stretcher leveling, degreasing, and brushing are Dass Steel service ...
