Stainless steel tube annealing Widely used abroad with a protective non-oxidizing gas Stainless steel tube annealing furnace , Production of intermediate heat treatment process and the final product heat treatment, since it is possible to obtain non-shiny surface oxidation, thus eliminating the traditional pickling process. This heat treatment process of adoption, both to improve the quality of steel, but also to overcome the acid wash the pollution of the environment.
Based on current trends in the development of the domestic steel pipe industry; I learn from foreign experience in production; newly developed three types of Stainless steel tube annealing furnace:
(1) Bright mesh belt heat treatment furnace. This furnace is suitable for small-diameter thin-walled precision steel tubes, hour production of about 0.3 to 1.0 tons, processing pipe lengths up to 40 m, can also be processed into a volume of capillaries.
(2) roller shaft bright heat treatment furnace. This furnace is suitable for large size, large quantities of steel heat treatment, hour production of 1.0 tons or more protective gas can be used for high purity hydrogen, the decomposition of ammonia and other protective gases can be equipped convection cooling system for rapidly cooling the steel pipe.
(3) Muffle bright heat treatment furnace steel tube mounted on the frame consecutive in the operation of the heating muffle, at a lower cost processing of high-quality small-diameter thin-walled steel pipe, hour production of about 0.3 tons.
