Steel forging cooling and annealing
Steel forging is a process of molding steel into larger shapes and sizes, usually using large hydraulic machines known as presses. It requires extreme precision and expertise to shape and form the steel without the risk of fracturing or over-hardening the steel, making it unsuitable for its purpose. As such, steel forging is of paramount importance for any steel-based industry.
In many cases, once the steel forging is completed, additional treatment is needed before the final product can be used. One such treatment often necessary for forming steel forgings is cooling and annealing.
Cooling is the process of cooling the steel down from the temperatures experienced during the forging process. This typically involves submerging the steel in a liquid coolant, oil, or water, depending on the type of steel being treated. The goal of cooling is to slowly decrease the temperature to a point such that the hardened steel returns to its original malleable state.
Annealing, on the other hand, is a process of heating the steel back up to a predetermined temperature in order to promote cleanliness within the steel’s crystalline structure. By heating the steel, impurities and air pockets are drawn out of the steel. During this heat cycle, the temperature is gradually increased and then slowly cooled, allowing for the steel to achieve maximum cleanliness and flexibility.
Once the cooling and annealing processes are completed, the steel forgings can be used for its intended purpose. Steel forging is a process that requires extreme precision and care, so it is important that cooling and annealing are done carefully and according to the specific needs of the steel. With the proper cooling and annealing, steel forgings can achieve the best results and be ready for use in any industry.
