摘要： PURPOSE:To subject a work to a sub-zero treatment with the simpler equipment and smaller amt. of liquid nitrogen than in the conventional methods of dipping the work into a cell contg. liquid nitrogen. CONSTITUTION:A flexible pipe 2 is disposed along a part 1a to be subjected to the sub-zero treatment of a work 1 and the liquid nitrogen is discharged from plural discharge holes 2a formed on this pipe 2 toward the part 1a to make sub-zero treatment of the part 1a. Equally good alternative is to execute the sub-zero treatment by depositing a liquid accumulating member absorbing and holding liquid on the part 1a and impregnating the liquid nitrogen into this liquid accumulating member.

摘要： PURPOSE: To prepare a coolant which can prevent liquefied nitrogen gas from vaporizing and can keep a low temperature for a long period of time by mixing liquefied nitrogen gas and powdered dry ice with stirring under the atmospheric pressure. CONSTITUTION: Liquefied nitrogen gas is poured in powdered dry ice (solidified carbon dioxide) in an amount of 0.7 pt.wt. of the nitrogen gas per 1 pt.wt. of the dry ice and they are stirred. The outlet nozzle for taking out the liquefied carbon dioxide from the vessel filled with liquefied carbon dioxide at 20kg/cm pressure is combined with the outlet nozzle for taking out the liquefied nitrogen gas from the vessel filled with the liquefied nitrogen gas at 5kg/cm and both liquefied gases are simultaneously jetted out into the cooling vessel and they are mixed with stirring.

摘要： PURPOSE:To facilitate machining with securing clearance precision, etc., by forming at least one fitting part of subzero cooling hardener between both of male-female fitting members and treating the fitting part by means of subzero cooling after carrying out clearance adjustment machining in the fixing part under the ordinary temperature. CONSTITUTION:At least a fitting part 4a of one member 4 to the other member between two members, which male-female fits each other, is formed of a subzero cooling hardener A which is hardened by subzero cooling. While the fitting part 4a is roughly machined, one member 4 is fitted to the other member to carry out clearance adjustment machining. Then, a coolant such as snow dry ice, etc., is heaped up on the fitting part 4a so that the fitting part 4a is treated by subzero cooling. In this way, clearance adjustment machining in the fitting part 4a can be carried out easily as the hardness of the subzero hardener A is low before subzero cooling. On the other hand, the hardness of the fitting part 4a is increased by subzero cooling without any distortion and abrasion resistance and clearance precision are secured.

摘要： PURPOSE:To easily and efficiently produce an appropriate amt. of snow dry ice. CONSTITUTION:A CO2 discharge nozzle 5 is provided at one end of a cylindrical vessel 1 with both ends closed, and high-pressure CO, discharged from the nozzle 5 is adiabatically expanded to form snow dry ice (a) in the vessel. The peripheral wall 2 of the vessel is formed with a gas-permeable material, and the air and excess CO2 are discharged to the outside through the wall 2. Consequently, the pressure in the vessel is not increased, and snow dry ice is efficiently formed.

摘要： PURPOSE:To execute sub-zero treatment for cooling a build up welded material joined at the edge part with a cooling material at low cost and in short time, e.g. to form trimming edge on a trimming metallic mold. CONSTITUTION:Rubber magnets 12, 12 are fixed along both side edges in the longitudinal direction of a flexible sheet 1 composed of aluminum wool and a pipe-like vessel 13 formed by mutually attracting both rubber magnets 12, 12 is connected with a liquefied carbon dioxide cylinder and snowy dryice 6 is filled into the inner part. By separating both rubber magnets 12, 12 and attracting to the edge part of the trimming metallic mold 1, the dryice 6 held in the inner part of the pipe-like vessel 13 is brought into contact with the build up welded material 3 in the trimming metallic mold 1 and the welded material is cooled. The pipe-like vessel 13 can repeatedly be used to the trimming metallic mold having various kinds of shapes.

摘要： PURPOSE:To efficiently execute a sub-zero treatment with a small amt. of coolant by suppressing the evaporation of this coolant as far as possible. CONSTITUTION:The coolant 3, such as dry ice, is built up on a part 2 formed of a sub-zero hardening material of a work 1. The coolant 3 is coated with a flexible heat insulating sheet 4. Laminated sheets formed by laminating a non air-permeable sheet layer 4b on a heat insulating sheet layer 4a are used as the heat insulating sheet. The infiltration of the evaporating gas from the coolant 3 and the atm. air into the heat insulating sheet 4a is prohibited by the non-air permeable sheet layer 4b. The heat exchange between the coolant 3 and the atm. air is thus suppressed as far as possible and the heat insulating characteristic is improved.

摘要： PURPOSE:To execute a good sub-zero treatment without generating unequal cooling by forming the prescribed part of a die of a sub-zero hardening material, building up pulverized dry ice in this part and subjecting the part to the sub-zero treatment. CONSTITUTION:The sub-zero hardening material to be hardened by the sub-zero treatment is build-up welded to the edge part 2 of the trimming die 1 and is machined to a prescribed shape. The dry ice 3 pulverized to a granular powder form is built up atop the edge part 2 in such a manner that a part of the ice projects to the outside of the edge part at the time of subjecting the edge part 2 to the sub-zero treatment. As a result, the dry ice 3 sinks on progression of evaporation and fits to the shape of the edge part 2. The edge part 2 is thus subjected to the cooling treatment without generating the unequal cooling.
