摘要： PURPOSE:To produce a rapid and uniform cooling effect with a small-sized cooling chamber and to economically and effectively carry out normalizing by utilizing the latent heat of vaporization for the cooling in the normalizing of a case-hardened steel. CONSTITUTION:A steel member 8 heated to a normalizing temp. in a heating chamber 1 is placed in a cooling chamber 2, and cooled. In this case, plural tubes 3 are arranged in the cooling chamber 2, and connected to a communicating tube 4. The insides of the tubes 3 are filled with hot water at a temp. immediately below the boiling temp. The temp. in the cooling chamber 2 is rapidly raised by the heat of the steel member 8 transferred to the cooling chamber 2 from the heating chamber 1, and the tubes 3 are also heated. As a result, the hot water in the tube is boiled, and violently vaporized. Meanwhile, the temp. of the periphery of the tube 3 is rapidly lowered by the latent heat of vaporization, the air surrounding the tube is cooled, and the steel member 6 is quenched by the cooled air circulated by a agitating fan 5. When the steel member 8 is cooled below 500 deg.C, the fan 5 is stopped, cooling is changed to annealing, and heat treatment free of strains is effectively carried out in the cooling chamber of a small size.

摘要： PURPOSE:To remove partial differences in cooling velocity in respective steel stocks and to prevent the occurrence of bend deformation by arranging plural steel stocks in a width direction and providing clearances between the steel stocks at both ends and the neighboring steel stocks, respectively, and then applying forced cooling to these steel stocks. CONSTITUTION:At the time of carrying out forced cooling by arranging plural steel stocks 1-7 in a width direction, clearances (l) are provided between the steel stocks 1, 7 at both ends and the neighboring steel stocks 2, 6, respectively. It is desirable to regulate the clearance (l) to 25-75mm. By providing the above clearances (l), differences in cooling velocity at both sides of respective steel stocks 1, 7 at both ends are remarkably relaxed and deformations all over the steel stocks 1, 7 are removed. As to the neighboring steel stocks 2, 6, the steel stocks 1, 7 at both ends exist at proper clearances (l) and, as a result, no steep temp. gradients are generated and the steel stocks 2, 6 do not cause large deformations. By this method, bend deformation due to the forced cooling of the steel stocks 1-7 can be prevented.

摘要： PURPOSE:To make the hardness and structure uniform and to improve the machinability and mechanical strength by cooling a hot forged rough body under specified conditions, working it to a prescribed shape, and carrying out secondary heat treatment. CONSTITUTION:A hot forged rough body is allowed to cool from the solubilization temp. to a temp. just above the austenite transformation point (A1 trans- formation point) at which transformation starts, and is slowly cooled until the transformation finishes after it starts to form a uniform two-phase structure consisting of ferrite and pearlite. The slowly cooled rough body is allowed to cool again to ordinary temp. The rough body is mechanically worked to a prescribed shape, and it is subjected to secondary heat treatment such as carburization and hardening, carbonitriding and hardening, or induction hardening to obtain a finished article.
