Description
Technical field
This utility model belongs to metallic conduit Technology for Heating Processing field, relates to a kind of pipeline Fast Field annealing device.
Background technology
Heat treatment is that steel is heated to predetermined temperature in the solid state, is incubated the regular hour, is cooled to a kind of heat processing technique of room temperature the most in a predetermined manner.Common heat treatment includes annealing, normalizing, quenches and be tempered；Surface heat-treatent (surface hardening: point induced surface hardening and flame surface quenching；Thermo-chemical treatment: point carburizing, nitriding etc.).
In order to reach preferable thermal effectiveness, the heat treating regime of steel for pipe is generally containing including preheating and gradient isothermal holding.The main purpose of preheating is the degree of hardening in order to reduce steel, reduces thermograde, reduces welding stress, delays the rate of cooling of weld seam, be beneficial to the effusion of hydrogen and improve stress condition, thus reduces the delayed crack tendency of joint.If interlayer temperature is not enough, it is equivalent to preheat temperature on the low side and do not reach the purpose of preheating；If but interlayer temperature is too high or preheating temperature is too high, easily causing overheated or produce joint plasticity and the decline of ballistic work, it is also possible to pearlite heatproof steel form " softened zone " in heat affected area, causes heat resistance to be decreased obviously.
Higher for design temperature (more than design temperature >=350 DEG C), high pressure, the Austenitic stainless steel pipe road (such as materials such as TP304, TP304H, TP321, TP321H, TP347 and TP347H) faced under the process conditions such as hydrogen, there is hydrogen-type corrosion iso-stress corrosion phenomenon, according to design document, need to carry out gradient heat treatment operation, process and stabilizing treatment etc. including postwelding stress-removal.Generally, this type of stainless steel pipes is heated to 900 ± 15 DEG C, is suitably incubated and constant temperature, make Cr23C6 dissolve, then forced air-cooling, form stable TiC or NbC, eliminate crystal boundary chromium depleted, and eliminate residual stress, it is ensured that the requirement of stress corrosion resistant.
At present, the many employings of pipeline heat treatment complete step by step, including solution heat treatment, aging strengthening model, destressing heat treatment etc., and institute's work consuming duration.
