Description
Technical field
The present invention relates to the technical field of post weld heat treatment, more particularly, to a kind of post weld heat treatment branch stake tool and postwelding
It is heat-treated support meanss.
Background technology
Power industry is the important support industry of national economic development.To ensure national power demand, economy, society are realized
Meeting, the coordination sustainable development of environmental protection, China's power industry are in a unprecedented high-speed development period, and firepower
Generating occupies high specific weight in China's supply of electric power.
Post weld heat treatment occupies an important position in the welding structures such as boilers and pressure vessel, pressure pipeline, at postwelding heat
Science and engineering work is the important process link of welding process, can significantly improve the performance of weld bond, and it is to ensure these part workmanships
A key measure.Lot of examples explanation both domestic and external, for dealing with improperly for this problem, it is possible to cause pressure-containing member
Major accident is produced in running.In heat treatment process, due to heating, the speed of cooling velocity, directly affect processed
The temperature difference between workpiece each point, excessive temperature differentials will produce larger thermal (temperature difference) stress, and weld seam or heat affecting will be caused when serious
The cracking in area.Wherein, the control of cooling velocity should be more strict, and stress caused by uneven heating can be with the liter of temperature
It is high and gradually relax, and stress caused by cooling down can remain, and form residual stress, endanger weld seam.The postwelding of weld bond
Heat treatment mainly has following arrangement and method for construction：When pipe away from it is larger when, crawler type heater can be used, every weld bond is independently arranged
One heater, the heater of more weld bonds are concatenated, and are heated using power supply all the way.At this moment it is noted that should be carried out to heater
Screening, makes the watt level of heater basically identical, ensures that the weld bond temperature of same stove heat is consistent.When pipe is away from smaller, it is impossible to single
When weld bond arrangement heater and heat-insulation layer, can use tracklayer heater, several weld bonds while with one or two heater
Several weld bonds are wrapped up together, heated simultaneously with power supply all the way, in pipe away from heater being furthered with iron wire, try one's best
Tube wall.Then in stove outer layer colligation heat-insulation layer, heat-insulation layer it is wider than heater go out 50-100mm, outside width of heating
All pipes is tight with insulation material plug away from gap, ensure the relatively stable of furnace air, make heating-up temperature uniform.Large-scale
Steel construction post weld heat treatment and preheating are also such.
For horizontal positioned tube panel or steel construction, because tracklayer heater porcelain block weight is larger, if colligation is loosely,
Bottom easily drops, and departs from processed part, makes section heaters radiating slow.Tube panel or steel construction bottom are due to the original of gravity
Because, and insulation material can not also be close on the heaters, there is gap, cause processed part heating irregular, heater in itself due to
Heat-transfer effect is reduced and overheat, and larger gravity is born during electric heating element high temperature and is stretched, it is possible to causes stratie
Damage, have impact on the first-time qualification rate of heat treatment, and the damage frequency and insulation material tenesmus for also increasing heat treatment heater draw
The temperature risen is unstable.
Based on problem above, propose a kind of keeping temperature stability and to meet at the postwelding heat of different heat treatment height
Reason branch stake tool is particularly important.
