摘要： PROBLEM TO BE SOLVED: To remove metal and nonmetal materials stuck on the surface of a material to be treated extremely well without using a special cleaning agent, combustion flame or the like. SOLUTION: In this method, after a material to be treated 1 is fed into a closed space 2 and the closed space 2 is evacuated, a non-oxidizing gas is fed and also primary heating is performed. Then, after the closed space is evacuated, secondary heating is further performed to evaporate liquid and solid materials stuck on the material to be treated 1 and the evaporated materials are housed in a condenser to condense them. Then, the non-oxidizing gas is fed again to cool the material to be treated 1. The oxidizing gas warmed by this cooling treatment is introduced into a preheating furnace 31 to preheat the untreated material to be treated 1.

CONSTITUTION:In the above continuous heat-treating furnace 1, the product 10 to be treated is laid on a mesh-belt 2, so that the part to be treated in the product 10 is positioned in the heating part 13. And, while circulating the belt 2 toward the direction of the arrow mark A, the product 10 is moved from the left side to the right side of the furnace 1 shown in the figure. Therefore, a part of product 10, passing through in the heating part 13 heated by a heater 17 and set at the prescribed temp., is heated at the above prescribed temp. On the other hand, while temp. of the other part of the above product 10 passing through the cooling part 14 is not practically raised the treating product is carried. In succession, after the product 10 partially heated at the prescribed temp. is carried out from the heating part 13 and the cooling part 14 of heating room 11, it is sent to a slow cooling room 12, to cool the above heated part at the prescribed cooling speed, and the treatment, such as gas quenching, tempering, annealing, normalizing, brazing, is executed.

摘要： PURPOSE:To reduce an initial cost by permitting simultaneous execution of heat treatment under different conditions by providing plural heating chambers which communicate with each other and are segmented by opening/closing doors to the rear of a front chamber. CONSTITUTION:The 1st heating chamber 4 and the 2nd heating chamber 5 are successively provided via the 1st intermediate door 6 to the rear of the front chamber 3 provided with a hardening vessel 2. The heating chambers 4, 5 are segmented from each other by the 2nd intermediate door 7. An article to be treated with which the treatment time is long is carried into the 2nd heating chamber 5 and an article to be treated with which the treatment time is short is carried into the 1st heating chamber 4. The 1st intermediate door 6 is opened and the article to be treated is transferred into an elevator 9 by opening the 1st intermediate door 6 prior to hardening. The elevator 9 is then lowered into the hardening vessel 2. The articles to be treated in the two heating chambers 4, 5 are successively hardened by such operation. The front chamber 3 is rationally and effectively utilized by the above-mentioned mechanism. The energy is economized by using the 2nd working chamber 5 for the carburization and the 1st heating chamber 4 for an adjusting chamber of the hardening temp., etc.

摘要： PROBLEM TO BE SOLVED: To simplify a surface treatment process before cold working to provide a sufficient rustproof effect and to realize deep drawing with its surface hardness reduced by achieving the element-removal treatment of only a surface part of iron and steel stock under the condition of high vacuum and high temperature. SOLUTION: Only a surface part of steel stock such as mild steel tubes is element-removed under the condition of 10-2-10-6 Torr in vacuum and 1000±250 deg.C in temperature. The treatment time is preferably approximately 0.5-10 hours. Evaporation of each element is promoted in a range of 5-80 millimicron in depth of the surface of a work treated in the vacuum treatment, the rustproof effect is improved because the surface is close to that of pure iron, the deep-drawing can be achieved because the surface hardness is small, and drawing cracks or residual stresses are reduced. Because pores are formed in the surface due to the surface element removing, the phosphate film treatment or painting becomes easy.
