Abstract

The invention relates to a heat treatment method for a super-alloy electromagnetic stirring roller used in a high-temperature environment. The heat treatment method comprises steps of placing an electromagnetic stirring roller which is made from a super-alloy UNSS66286 material in a heating electric furnace, and sequentially implementing solution treatment, aging treatment and stabilizing treatment to obtain a super-alloy UNSS66286 electromagnetic stirring roller used in a high-temperature environment, wherein the product processed by heat treatment can be used in a 650 DEG C high-temperature environment. The UNSS66286 electromagnetic stirring roller which is prepared through the heat treatment and is applicable to a high-temperature environment has excellent tensile strength, yield strength, elongation, shrinking percentage, hardness, grain size and high temperature endurance property, the UNSS66286 electromagnetic stirring roller prepared by the heat treatment greatly has high service life; through test, the UNSS66286 electromagnetic stirring roller cannot be worn and fractured after being used for 2 years, thus greatly prolonging the service life.

Description

technical field [0001] The invention relates to a heat treatment method of a superalloy electromagnetic stirring roller for high temperature, in particular to a heat treatment method of a superalloy UNS S66286 electromagnetic stirring roller for high temperature. Background technique [0002] The heat treatment process of the electromagnetic stirring roller made of UNS S66286 material currently used is as follows: the electromagnetic stirring roller made of UNS S66286 material is first heated to 980°C for 1 hour, then water-cooled, then raised to 720°C for 16 hours, and then air-cooled. Obtain the electromagnetic stirring roller made of the existing UNS S66286 material. The electromagnetic stirring roller of UNS S66286 material obtained by this heat treatment process has been tested, and the test results are shown in Table 1. [0003] Table 1 [0004] [0005] It can be seen from Table 1 that the room temperature mechanical properties and high temperature durability of ...
