Abstract
The invention relates to a heat treatment process for a large seal head. The heat treatment process comprises the steps that the large seal head is put into a large heat treatment chamber for first heat treatment, and the large seal head is put into the large heat treatment chamber for secondary heat treatment. The heat treatment process is conducted integrally, control is precise, and the product quality is improved effectively.
Description
Technical field
The present invention relates to a kind of Technology for Heating Processing, be specifically related to a kind of seal head heat treatment technology.
Background technology
Currently for the heat treatment of large-sized end enclosure, the method not having controllable precise, bulk heat treatmet poor effect, product quality is the highest, does not meets actual operation requirements.
Summary of the invention
Goal of the invention: the invention aims to overcome deficiency of the prior art, it is provided that a kind of entirety is carried out, controls accurately, to be effectively improved the Technology for Heating Processing of the large-sized end enclosure of product quality.
Technical scheme: in order to solve above-mentioned technical problem, the Technology for Heating Processing of large-sized end enclosure of the present invention, it comprises the following steps,
(1) large-sized end enclosure is put into large-scale thermal chamber and carry out a heat treatment: during entrance, large-scale heat treatment indoor temperature controls at 300-400 DEG C, then it is heated to 500-550 DEG C with 3-5 DEG C/min, insulation 2-3h, then 400-450 DEG C is cooled to 5-8 DEG C/min, remove large-scale thermal chamber, carry out natural cooling；
(2) large-sized end enclosure is put into large-scale thermal chamber and carry out secondary heat treatment: during entrance, large-scale heat treatment indoor temperature controls at 400-450 DEG C, then it is heated to 600-650 DEG C with 5-8 DEG C/min, insulation 2-3h, then 300-350 DEG C is cooled to 8-10 DEG C/min, remove large-scale thermal chamber, carry out natural cooling.
Beneficial effect: compared with prior art, its remarkable advantage is the present invention: large-sized end enclosure directly entirety is put into large-scale thermal chamber by the present invention, carries out disposed of in its entirety, and carry out secondary heat treatment, temperature controls accurately, to be effectively improved product quality, meet actual operation requirements.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further illustrated.
