904L stainless steel Hot extrusion technology of special section steel for pipe

Tianjin Stainless steel pipe Based on the data and experience obtained during the test under the production conditions, combined with the relevant data used in the test, the advantages and existing problems of warm and hot extrusion, the selection of processing temperature, the measurement and calculation of extrusion pressure and deformation force, the selection of lubricant, the design of die and the performance and quality of products are summarized, In order to better and more widely use this new pressure processing technology in the future.


It can make the hard to deform material to be processed. General hot extrusion press is the production of tubular 904L Hot extrusion technology of stainless steel pipe and special section steel / hot extrusion technology of special section steel developed by Japan steel pipe company. If various dies or dies and mandrel are used, steel with complex cross-section can be produced. The section size and extrusion length of the product generally depend on the pressure of the extruder and the capacity of the die. The company has a maximum mold size of 330mm Using 904L stainless steel tube blank with large diameter of 1200mm, special section steel with large section can be processed. In addition, glass lubricant is used, tool design and extrusion conditions are optimized, and the cladding compound extrusion technology is used to produce special section steel satisfying customers. For the uneven metal flow phenomenon in the past, the company adopts to disperse the metal plastic deformation concentrated in the central part to the left and right parts, so as to control the change of the internal width between the head and tail of the extrusion profile, so as to achieve the results that the dimensional accuracy meets the requirements. In 1973, Qing'an company and northwest Polytechnic University cooperated with each other to carry out a series of technological tests on warm hot extrusion in combination with the technical innovation project of Qing'an company, and checked the performance and quality of the products. The preliminary satisfactory results have been obtained in these studies, and the products selected for the project have been put into trial production.
