Screen grabber chrome10/31/2022 ![]() ![]() Equipped with convection cooling system for fast cooling. It can also be used to process capillary tubes in coils. The length of the steel pipe can be up to 40m. The hourly output is about 0.3 to 1.0 Tons. This bright annealing furnace type is suitable for small-diameter thin-walled precision special-shaped stainless steel pipes. (2) Mesh belt type bright annealing heat treatment furnace. It can be equipped with a convection cooling system to cool the special-shaped stainless steel tube faster. The protective gases that can be used are high-purity hydrogen, decomposed ammonia and other protective gases. This bright annealing furnace type is suitable for heat treatment of large-size and large-volume special-shaped stainless steel pipes, with an hourly output of above 1.0 Tons. (1) Roller-type bright annealing heat treatment furnace. The adoption of this heat treatment process not only improves the surface of stainless steel pipes, but also overcomes the environmental pollution caused by pickling.Īccording to the manufacturer of stainless steel pipes, according to the current world development trend, bright annealing continuous heat treatment furnaces are basically divided into the following two types: As a bright surface without oxidation can be obtained, the traditional pickling process is eliminated. Heat treatment technology of stainless steel pipe surfaceįor the heat treatment technology of the surface of stainless steel pipes, non-oxidation continuous heat treatment furnaces with protective gas are generally used abroad for intermediate heat treatment and final heat treatment of finished products.
