Hot-rolled steel is a steel that had roll-passed at a very high temperature, approximately more than 2000 degrees Fahrenheit which is above the recrystallization temperature for most steel types.The heat gives steel a workable starting form and makes it easier to shape.Hot rolling starts with a large long steel called billet which is heated and sent to a large roll to flatten, then it is passed in a series of rolls keeping it’s high temperature until reaching to the final wanted dimensions.Then steel sheets are spun into coils and left to cool.
Hot-rolled coils are one of the flat steel products. They are sheets of prime or second choice steel that are rolled in a hot steel mill into coils while they are very hot. These coils are very common types of steel coils that form the base product for other steel coils like coated and galvanized coils and also used directly nearly in various industries and machinery, like construction, shipbuilding, automotive…etc.
