Salt bath heat treatment molten salt device and control method thereof

Abstract

The invention relates to a salt bath heat treatment molten salt device and a control method thereof. The control method comprises the steps that a molten salt device body is arranged on the salt bath heat treatment molten salt device; the molten salt device body is heated when being used for quenching, and molten salt is contained in the molten salt device body; a lifting basket is arranged in the molten salt device body in the preset axis direction; during quenching, the basket is immersed in the molten salt; a heating device is arranged on the outer side of the molten salt device in the preset direction of the molten salt device; the heating device is used for heating heat treatment material in the molten salt; a cold quenching device is arranged on one side of the molten salt device; and a main control device controls the temperature and heating time of the molten salt device, after the heat treatment material is heated, the heat treatment material is moved into the cold quenching device to be quenched, or the main control device controls the temperature and heating time of the molten salt device, and the heat treatment material is annealed. According to the salt bath heat treatment molten salt device and the control method thereof, the functions of annealing and quenching are achieved at the same time, and the heat treatment process can be automatically carried out without manual intervention, so that the purposes of improving efficiency and saving cost are achieved.

Description

technical field [0001] Embodiments of the present invention relate to a heat treatment molten salt device, in particular to a salt bath heat treatment molten salt device and a control method thereof. Background technique [0002] In the existing heat treatment process of titanium alloy materials used for heart stents, both quenching and annealing of titanium alloy materials are required. In the existing technology, it is difficult to avoid Oxidation of alloy materials during heat treatment. Since the quenching and annealing processes are not on the same equipment, there is no way to control the oxidation of titanium alloy materials used for heart stents during heat treatment. It is necessary to solve the problem of one equipment that can simultaneously Realize the annealing and quenching functions, and the heat treatment process can be automated without manual intervention; thus achieving the purpose of improving efficiency and saving costs.
