Problems solved by technology

[0014] However, as in the cryogenic treatment apparatus 100 disclosed in Patent Document 1, if the low-temperature nitrogen gas is discharged to the outside of the cooling tank 102 through the exhaust port 102A penetrating the side wall of the cooling tank 102, temperature fluctuations will occur in the cooling tank 102. Stablize
[0015] In this way, if the temperature is unstable in the cooling tank 102, the cooling of the object to be cooled 101 will be uneven, and the quality of the object to be cooled 101 will be unstable.

Abstract

The present invention provides a sub-zero treatment device capable of uniformly cooling a cooling target object and reducing the amount of liquid refrigerant used for cooling the cooling target object. The sub-zero treatment device has an exhaust member extending from a through-hole provided in a cooling tank constituting a cooling target object mounting chamber through to the interior of the cooling target object mounting chamber, and having an exhaust port, wherein the exhaust port is disposed in an exhaust port positioning space, which is the space located in the upper half of the cooling target object mounting chamber and having a width in the transverse direction that is equal to the maximum width in the transverse direction of the suction port.

Description

technical field [0001] The invention relates to a cryogenic treatment device for improving properties such as hardness and toughness by cooling iron and steel materials such as mechanical parts to a low temperature below 0°C. [0002] this application claims priority based on Japanese Patent Application No. 2013-060698 for which it applied to Japan on March 22, 2013, and uses the content here. Background technique [0003] Conventionally, in order to improve performance such as height and toughness of steel materials such as machine parts, cryogenic treatment is performed to cool steel materials such as machine parts to a low temperature below 0°C. [0004] As one of the cryogenic treatment methods, there is known a low-temperature atmosphere method of cooling the object to be cooled by cooling the atmosphere gas in a cooling tank for storing the object to be cooled by a refrigerator or liquid nitrogen. [0005] Patent Document 1 discloses a cryogenic treatment device used ...
