Description of drawings
Fig. 1 is the structural representation of the amorphous alloy iron core thermal treatment unit that one embodiment of the invention provided.
Embodiment
For above-mentioned feature and advantage of the present invention can be become apparent, exemplary embodiment cited below particularly, and conjunction with figs. are described in detail below.
Please refer to Fig. 1, it is the structural representation of the amorphous alloy iron core thermal treatment unit that one embodiment of the invention provided.As shown in the figure, this amorphous alloy iron core thermal treatment unit comprises the bracing frame 20 of heat treatment furnace 10 and removable turnover heat treatment furnace 10, and bracing frame 20 has a plurality of equally distributed fulcrums 21, in order to support a plurality of amorphous alloy iron cores 100.This amorphous alloy iron core thermal treatment unit also comprises furnace temperature transmitter 30, a plurality of iron core temperature sensor 40 and temperature regulator 50, and wherein furnace temperature transmitter 30 is arranged in the heat treatment furnace 10, to measure furnace temperature; A plurality of iron core temperature sensors 40 when a plurality of amorphous alloy iron cores 100 place on the bracing frame 20, lay respectively at a plurality of amorphous alloy iron cores 100 inside, with the real time temperature of monitoring amorphous alloy iron core 100; Temperature regulator 50 is connected with a plurality of iron core temperature sensor 40 signals with furnace temperature transmitter 30, and according to these transmitter institute sensed temperature, adjusts the heating power of heat treatment furnace in real time.
To have iron core temperature sensor 40 in order making in each amorphous alloy iron core 100, can on bracing frame 20, an iron core temperature sensor 40 to be set the position of corresponding each fulcrum; Perhaps after placing amorphous alloy iron core 100 on the bracing frame, respectively an iron core temperature sensor 40 is inserted amorphous alloy iron core 100 inside.
Like this, in the amorphous alloy iron core heat treatment process, a temperature sensor is used to measure furnace temperature, and a plurality of in addition temperature sensors insert core interior, is used to monitor the real time temperature of amorphous alloy iron core.And adjust the heating power of heat treatment furnace in real time according to these temperature, the control corresponding furnace temperature guarantees that iron core is heated evenly unanimity, heats up, is incubated, lowers the temperature according to specific program.So both can avoid because the iron core temperature hysteresis in furnace temperature, makes iron core holding temperature or soaking time not enough, and influences the elimination of iron core stress; It is too fast to avoid part iron core temperature to raise again, causes iron core mis-behave and inhomogeneous.
Describe in detail below and utilize above device to carry out the heat treated process of amorphous alloy iron core.
At first, bracing frame 20 is shifted out the burner hearth 12 of heat treatment furnace 10.Then pending a collection of amorphous alloy iron core 100 is placed on the bracing frame 20; In put procedure, iron core on the same support bar 22 needs consistency from top to bottom to place, and is reserved with certain space between each layer iron core, blows to top to guarantee hot blast from the bottom of burner hearth 12, guarantee that each layer iron core is heated evenly unanimity, the uniformity consistency of enhancing product performance; In addition, iron core temperature sensor 40 is convenient to insert in the space of reservation.After amorphous alloy iron core 100 placements finished, the burner hearth 12 with bracing frame 20 immigration heat treatment furnaces 10 closed upper furnace door 11, begins heating.In heat-processed, to utilize furnace temperature transmitter 30 and iron core temperature sensor 40 monitoring furnace temperature and iron core temperature in real time, and adjust the heating power of heat treatment furnace in real time according to these temperature, the control corresponding furnace temperature guarantees that iron core is heated evenly unanimity.Whole heat treatment process is: at first charge into nitrogen to get rid of the air in it in burner hearth 12, heat up according to certain temperature rise rate then, treat that temperature reaches setting and requires back insulation for some time, lower the temperature by certain speed again, at last, bracing frame 20 is shifted out the burner hearth 12 of heat treatment furnace 10, finish thermal treatment this batch amorphous alloy iron core 100.
Accordingly, one embodiment of the invention also provides a kind of amorphous alloy iron core heat treating method, and it utilizes the furnace temperature of temperature sensor measurement heat treatment furnace; Simultaneously, utilize the real time temperature of the pending a plurality of amorphous alloy iron cores of other a plurality of temperature sensor monitors; According to the real time temperature of the furnace temperature of being measured and a plurality of amorphous alloy iron cores, adjust the heating power of heat treatment furnace in real time.
Usually, the heat treatment process of amorphous alloy iron core three processes that comprise intensification, are incubated and lower the temperature, and above method often is applied to heat up and insulating process, and when begin to lower the temperature in order to the section of declaring.
Particularly, before heat-treating, often preestablish furnace temperature scope and amorphous alloy iron core temperature range.When the real time temperature of all amorphous alloy iron cores reaches its default temperature range, insulation for some time; The cooling of lowering the temperature is then reduced to room temperature until all amorphous alloy iron core temperature.Specifically, the furnace temperature scope can be set at 300～400 ℃, the iron core temperature range is set at 290～390 ℃, treat to pick up counting when cored temperature reaches set(ting)value, then be incubated 20 to 240 minutes, stop heating then, begin the cooling cooling, reduce to room temperature until the iron core temperature, enter next process.
When using above method the batch iron core being heat-treated, both can guarantee that iron core was heated evenly unanimity, and can guarantee the utilization ratio of burner hearth again, enhance productivity, thereby improve the uniformity consistency of product performance.
Above-described temperature sensor can be made of thermopair, and certainly, the present invention is not as limit, and those skilled in the art can select for use other temperature sensors to be realized under this prompting.
In sum, because intensification, holding stage in heat treatment process, adopt the temperature of a plurality of each amorphous iron cores of temperature sensor monitors, the corresponding heating power of adjusting heat treatment furnace, thereby guarantee the homogeneity and the synchronism of amorphous iron core heat treatment process, effectively improved the electromagnetic performance of amorphous iron core product, made product percent of pass, obviously increased economic benefit near 100%.
