Description
Technical field
The invention belongs to METAL HEATING PROCESS field, more particularly, to a kind of metal bar material heating device.
Background technology
Traditional Forge Heating is all to use induction diathermic, and a heating furnace is only used for a kind of bar diameter, and is limited to
Different bar diameters are required more heating furnaces by whole heating.Local heating is required to be only limited to small-power short distance
From.It need to especially do over again material in forging process, induction diathermic just cannot achieve, and cause tremendous economic to bear to forging process.
Sensing heating is since the kelvin effect in exchange is in one cyclic annular heating layer of material surface formation.Heat by table to it is inner with
Conduction pattern transmits.General processing technology has the uniformity of charge-temperature certain requirement.For induction diathermic furnace, temperature
Uniformity radial temperature difference, axial temperature difference are weighed.Heating layer depth depends on power frequency and furnace charge property and its section ruler
Very little (heating layer under normal circumstances, limiting value R are material radius).Thus in addition to power and the frequency for reasonably selecting equipment,
There must also be enough heat transfer times, to ensure that the uniformity axial temperature difference of temperature comes across batch furnace and walking beam furnace more.
The heat radiation under scattering and the condition of high temperature due to induction coil magnetic fidle of end keeps magnetic field at this and temperature relatively low.Coil around
When the pitch of turn unevenness and three-phase inductor of system assemble successively in an axial direction, phased magnetic field slackens, and can all cause batch furnace and step
Into in formula stove, there is low temperature band in material.
Invention content

Depressor.
Further, further include that can control the clamping device for heating electrode position, the heating electrode is fixed on
On the clamping device.
The invention has the advantages and positive effects of.
Bar both ends are fixed between two electrodes metal bar material heating device, it can be achieved that whole heating.By bar position
It is fixed between two electrodes, it can be achieved that part and whole heating.It is visual to contact electrical heating process, is convenient for thermometric, carries simply, is easy
Realize forging automation.It is small to contact the electrical heating whole cross section temperature difference, is not easy overtemperature, is suitable for the small difficult control of heats forged temperature range
Adiabator.
Metal bar material heating device is mounted in sheared blank production line, can be realized bar hot shearing, be made metal bar material
Shear fracture is more smooth, prevents shear fissure from generating.
