The difference between continuous roll and cast steel
2024/04/24
Roller is a tool for rolling metal materials, and its varieties and manufacturing processes continue to progress with the development of metallurgical technology and rolling equipment. Middle Ages rolling soft non-ferrous metals using low-strength gray cast iron rolls, the middle of the 18th century Britain mastered the production technology of cold hard cast iron rolls for rolling steel plates. In the second half of the 19th century, the progress of European steelmaking technology required rolling larger tonnage of steel ingots, and ordinary cast steel rolls with carbon content of 0.4~0.6 came into being. The use of alloying elements and the introduction of heat treatment in the early 20th century improved the wear resistance and toughness of cast and forged steel hot and cold rolls.
