Temperature processing technology and its application in thick-walled container

, For example, 45 actinium, 35CrMo steel blue brittle area is 500 ~ 600 ~ C, temperature processing temperature above 650 ℃ can choose. Ring, while operating conditions are better than thermal processing. This is exactly the temperature of attention because processing of gradually. 4 temperature processing in the application of thick-walled vessel manufacturing system I'm Luoyang refinery plant thick-walled container (extractor, glial Settler), plates for the SA516, Simplified and head thickness is 75ram, its simplified the original to be cold roll forming, after the lack of capacity due to equipment, then to warm roll forming, with satisfactory results. 4.1 Determination of temperature and roll temperature of 112-1981 under the provisions of a Japanese HPISE, SA516 lowest final temperature of heat treatment after welding 550 l curve indicated that steel in this temperature rise is in the plastic stage, came out to be rapidly taking shape. Forming process should avoid the blue brittle temperature, when the temperature gradually decreased from the 530 ~ C to 400 ℃ should be stopped forming, can be reduced to 30O ~ C the following to continue rolling, or melted down and then reheated to rolling. Rolling process temperature curve shown in Figure 2. 4.2 Temperature and temperature control roll rolling process in order to avoid the blue brittle temperature zone,[link widoczny dla zalogowanych], the temperature on the forming process should be controlled. Taking into account the plate surface in contact with cold air or the temperature will drop rapidly after the roll, with the contact surface temperature measuring device measured the temperature does not reflect the actual temperature of the plate, and can not be quickly formed between the short barrel of the festival, best plate edges parallel to the board tax drilled quite thick / 2 hole, aperture 3.2ram about 3mm into the armored thermocouple temperature to control the forming temperature. 3.3 Conclusion temperature processing temperature and processing advantages of the superiority of 5 is obvious, it can solve the cold material a large plastic deformation resistance, the problem of insufficient power processing equipment,[link widoczny dla zalogowanych], thermal processing and avoid the oxidation, decarburization, heat, burning and other defects, and can save energy. In addition, the temperature of processing can not guarantee the performance of materials, processing film forming temperature and the current application is not yet common, people used to use cold and heat processing, temperature and processing advantages of a lack of awareness, along with the development and production of temperature process of research, people on the temperature will gradually deepen understanding of processing, the application will also be more extensive.

Journal of the workers from the community of new millet, 1982.2 stamping waste production and prevent 200 cases of defective forthcoming book by flash hundred plants from the national collection of 20O a typical example, in punching,[link widoczny dla zalogowanych], bending, pulling deep, bulging, Hu repeatedly Forming the other side of the production site is the degree of pressing parapet analyzed defective practical experience and theoretical analysis based on proposed control and improve the quality of stamping the book discusses the measures the quality of personnel, management, accuracy of press and die structure, stamping raw materials, operation and methods of measurement, and environmental factors such as resistance to stamping quality. examined the difference between stamping process, interconnected, and the possible conversion between processes. book known example of a The real side of the involved instrumentation,[link widoczny dla zalogowanych], automobiles, tractors, electric locomotives, electrical, hardware, defense, electronics and home appliances industries. both practical experience and theoretical analysis. content-rich, easy to understand. This book is stamping sector scientific and technological personnel, university and college teachers long-term scientific experiments and production practice of the results and lessons learned, practical production problem solving, improve the stamping technology, bitter. to improve the level of technology and total quality management are very beneficial. This book can be engaged in stamping and tooling for the process of professional designers, production workers, administrators and researchers for reference, but also as the mouth of the small colleges and forging a reference book for teachers and students with professional touch. the book into the temple Guo,[link widoczny dla zalogowanych], Xi'an Jiaotong University, Xi'an Instrument Factory Zhaoxin Huai Shu six weeks Changzhou Tractor Plant is expected to published in 1993 compiled.
