Thick-walled straight seam steel pipe baked and furnace: baked is the processing commonly used in the preparation of heat treatment process. Most of the machine parts and workers, mold blank after baked, can eliminate casting, forging and welding parts of the internal stress and composition of the organization of non-uniformity; to improve and adjust the mechanical properties of straight seam steel pipe, Organization preparation. The performance requirements are not high, less important parts and some ordinary castings, weldments, baked can be used as the final heat treatment. Baked is the temperature of the steel pipe to the appropriate strength, heat for a certain time, and then slowly cooling, in order to get close to the organization of the heat treatment process.
