Updating the Mode of Annealing of Tubes from Steel ShKh15 in Chamber Furnaces

Аннотация

A study of commercial tubes from steel ShKh15 produced in a chamber furnace is performed for investigating the active annealing process. The causes of inappropriate heating and cooling of tubes in a charge are determined. The annealing mode is shown to mismatch the required temperature regime, which elevates rejection. Recommendations for eliminating the determined drawbacks, raising the quality of the annealed tubes and the output of the chamber furnaces are developed.
