After the steel wire is lead-quenched, the steel wire is heated to a temperature above AC3 for a certain period of time to obtain uniform austenite, and then the cooling temperature and time are controlled to decompose the austenite into sorbite. In the production of steel wire, the Soxhlet can be used as a heat treatment before drawing the product. Such as: prestressed steel wire, spring steel wire, etc.
The sorbite is a mixture of iron quality and cementite obtained by the temperature conversion of the steel. The sorbite has good mechanical properties. The processing of the steel wire to obtain the sorbite is beneficial to the stability of the product.
