Description

Solid solution treatment furnace for weight manufacturing

Technical Field

The utility model relates to a technical field of solution treatment stove especially relates to a solution treatment stove is used in weight manufacturing.

Background

Solution treatment (solution) refers to a heat treatment process in which an alloy is heated to a high temperature in a single phase region and kept at a constant temperature, so that an excess phase is sufficiently dissolved in a solid solution and then rapidly cooled to obtain a supersaturated solid solution.

The operation process is similar to quenching, and is also called solution quenching. The method is suitable for the alloy which takes solid solution as a matrix and has larger solubility change when the temperature changes. Firstly, the alloy is heated to a certain proper temperature above the solubility curve and below the solidus line and is kept for a certain time, so that the second phase is dissolved in the solid solution. Followed by rapid cooling in water or other medium to inhibit re-precipitation of the second phase, a supersaturated solid solution at room temperature or a solid solution phase which is normally present only at elevated temperatures can be obtained. Since thermodynamically in a metastable state, desolventization or other transformations will occur under appropriate temperature or stress conditions. Generally, the heat treatment is a preliminary heat treatment, which is performed to prepare optimum conditions for the subsequent heat treatment.
