A kind of titanium alloy solid solution heat treatment furnace and solid solution method

Abstract

The present invention provides a titanium alloy solid solution heat treatment furnace and a solid solution method, the furnace comprising a feed mechanism, a charge-in mechanism, a furnace body and a water-cooling mechanism. A solid solution cavity that is formed from the charge-in mechanism, the furnace body and the water-cooling mechanism effectively ensures that products to be subject to solid solution are protected from air in the processes of heating and heat preservation, a transfer plate in the furnace body can control the time of heating and heat preservation of products in the furnace body by adjusting the transmission frequency, products are transmitted to the place above a material falling channel and put into a water tank after heat preservation ends, and the time for the products to move from the material falling channel to the water tank is the solid solution transfer time. The solid solution transfer time can be controlled shorter than 2s, which is remarkably shortened compared with that of traditional equipment. Through the titanium alloy solid solution heat treatment furnace and the solid solution method provided in the present invention, it can be guaranteed that products are unlikely to be oxidized in the process of water-cooling solid solution, and the solid solution time is short, which ensures the mechanical properties of the products after solid solution. The titanium alloy solid solution heat treatment furnace and the method are easy to use, and ensure that the products are of a high qualification rate.

Description

technical field

[0001] The invention belongs to the field of heat treatment equipment and a heat treatment method, and in particular relates to a heat treatment equipment and a heat treatment method of a titanium alloy. Background technique

[0002] Titanium alloy has the characteristics of low density and high strength, and is widely used in aviation and aerospace equipment. However, when titanium alloys are water-cooled and solid-soluted, the requirements for heat treatment equipment are extremely strict.

[0003] The solid solution method of titanium alloy is to put a single piece of titanium alloy into the furnace, heat it for a certain time and temperature, and then take it out for rapid cooling. The purpose is to stabilize the temperature of the titanium alloy below room temperature through rapid cooling and maintain a good Process plasticity to facilitate reprocessing. Because titanium alloy is very easy to age, and the aging temperature is below the solution temper...
