Stress Free Steel and Rapid Production of Same
First Claim
1. A method of producing steel product with reduced internal stress, comprising the steps of:
- processing a semis with a rolling mill to create a steel product;
preparing a bundle of the steel product while the steel product is still hot;
cooling the bundle of steel product;
generating a magnetic field;
exposing the bundle of steel product to the magnetic field; and
vibrating the cooled bundle of steel product so as to relieve unwanted internal stress concentrations present in the steel product, wherein the vibration occurs from the steel product expanding and contracting while exposed to the magnetic field.

Abstract
A method of producing steel with reduced internal stress concentrations is disclosed. In an embodiment, hot steel is shaped by a rolling mill. The resultant steel product is bundled as soon as practicable and the bundle is allowed to cool. Vibration energy is applied to the bundle of steel product so that internal stress concentrations within the steel product are relieved. In an embodiment, a plurality of bundles are stored on a rack and the rack is vibrated, the vibrations being transmitted to the plurality of bundles so that undesired internal stress concentrations within the steel products are relieved. Alternatively, magnetics may be used to relieve the undesired internal stress concentrations within the steel products. Thus, improved steel is produced as well as improved steel that can be produced more rapidly than known techniques.
