By taking the structure of heating system 3 shown in Fig. 2 as an example, to what is heated using heating system 3 to magnesium alloy board
The working principle of method is illustrated:
The middle part target temperature T1 and edge target temperature T2 of magnesium alloy board 1 are set to heating system 3 by controller,
And it is provided with maximum temperature difference Δ T, when magnesium alloy board 1 enters heating system 3, middle part temperature measurer 3211 and edge
The measurement of temperature measurer 3221 enters the middle part of magnesium alloy board 1 and the temperature of edge of heating component 32, the middle part that will test with
And the temperature of edge is sent to controller, controller is computed heating power required for acquisition and issues heating power and heats
It instructs onto middle part heater 321 and strip edge heater 322, middle part heater 321 and strip edge heater 322 are according to fever
Instruction carries out induction heating, while middle part displacement sensor 3212 and edge position to the middle part of magnesium alloy board 1 and edge
The distance at the detection of displacement sensor 3222 middle part heater 321 and strip edge heater 322 middle part and edge away from magnesium alloy board 1
D1, d2 and d3 (wherein d2, d3 refer to edge two sides respectively apart from the distance of magnesium alloy board), the distance d1 that will test,
D2 and d3 numerical value is sent to controller.In addition, middle part temperature measurer 3211 and edge temperature measurer 3221 continue real-time detection magnesium
The middle part of alloy sheet strip 1 and the temperature of edge, and the temperature measured is sent to controller, controller calculates magnesium alloy in real time
The Temperature Distribution in plate width direction, and being compared with middle part target temperature T1 and edge target temperature T2, when middle part and
When the temperature of edge reaches middle part target temperature T1 and edge target temperature T2, then heating power and middle part heater 321 are maintained
And distance d1, d2 and d3 at middle part and edge of the strip edge heater 322 away from magnesium alloy board 1；And arrived when real-time detection
The temperature of middle part and edge is different from target temperature, and when the difference of the two is more than maximum temperature difference Δ T, then controller root
Distance d1, d2 and d3 according to middle part heater 321 and strip edge heater 322 apart from magnesium alloy board 1 are controlled to adjust,
Corresponding regulative mode and adjustment parameter are set, and corresponding regulative mode and adjustment parameter are sent to by regulating command
Middle part is displaced regulating mechanism 331 and/or edge is displaced regulating mechanism 332, and middle part is displaced regulating mechanism 331 and/or edge displacement
Regulating mechanism 332 increases or reduces distance according to regulating command execution.
Such as: when the temperature at the middle part of magnesium alloy board 1 is lower than middle part target temperature T1, adjusting machine is displaced by middle part
Structure 331 reduces middle part heater 321 and 1 distance d1 of magnesium alloy board, until the temperature at the middle part of magnesium alloy board 1 reaches
Target temperature T1.
Another example is: when the temperature at the middle part of magnesium alloy board 1 reaches middle part target temperature T1, the temperature and edge of edge
When the temperature gap of target temperature T2 has been more than maximum temperature difference Δ T, then regulating mechanism 332 is displaced by edge and distinguishes opposite side
Portion's heater 322 carries out separately adjustable with 1 distance d2, d3 of magnesium alloy board.When the temperature of measured edge is higher than edge
When target temperature T2, then the distance of d2, d3 are increased；And when the temperature of measured edge is lower than edge target temperature T2,
Then the distance of d2, d3 are reduced.If leading to the temperature of 1 edge of magnesium alloy board due to 1 irregular deformation of magnesium alloy board
Side be higher than edge target temperature T2, and the other side be lower than edge target temperature T2 when, then can will be above edge target temperature
The distance of the side strip edge heater 322 of T2 reduces, and side strip edge heater 322 lower than edge target temperature T away from
From increase.
Again for example: when the temperature at the middle part of magnesium alloy board 1 is higher than middle part target temperature T1, being then displaced and adjusted by middle part
Middle part heater 321 and 1 distance d1 of magnesium alloy board will be reduced by saving mechanism 331, and when d1 is adjusted to minimum, temperature is still higher than
When the target temperature T1 of middle part, then the heating power of middle part heater 321 can be reduced by controller, until magnesium alloy board 1
Middle portion temperature be adjusted to middle part target temperature T1.
It, can be by adjusting magnesium alloy plate when the Edge band of magnesium alloy board 1 is symmetric deformation by the above method
With edge at a distance from strip edge heater 322, keep d2 and d3 of substantially equal, magnesium alloy board and middle part heater 321, edge
The distance of heater 322 is adjusted according to the board temperature for being magnesium alloy board, reaches mesh at the middle part of magnesium alloy board and edge
When marking temperature, may exist difference between d2 and d3；And if magnesium alloy board edge occur irregular deformation when, can be independent
D2 and d3 is adjusted respectively, until the middle part of magnesium alloy board and edge are adjusted to target temperature.
It can thus be seen that for the heating system in this case, even if the feelings that strip two sides itself are inconsistent there are spacing
Condition can also meet middle part target temperature T1 by the temperature of setting middle part and edge using Temperature Distribution as foundation is adjusted
With edge target temperature T2, meet the requirement of Temperature Distribution technique to reach, not without the two sides spacing due to magnesium alloy board 1
Distance that is consistent and adjusting middle part heater 321 and strip edge heater 322 middle part and edge away from magnesium alloy board 1, from
And realize being evenly heated of 1 plate width direction of magnesium alloy board, edge temperature is higher than middle portion temperature, edge temperature is lower than middle part temperature
The adjusting of degree or other customization Temperature Distributions.
It should be pointed out that middle part heater 321 and strip edge heater 322 are only arranged in embodiment shown in Fig. 2
One heater monomer, but in some other embodiments, middle part heater 321 and strip edge heater 322 plus
Hot device monomer can be set multiple, and the number of heater monomer can be selected according to the concrete condition of each embodiment, example
As middle part heater 321 can be set to one to eight middle part heater monomer, and strip edge heater 322 can be set to one to
Four strip edge heater monomers.Wherein, Fig. 3 and Fig. 4 shows that the strip edge heater in heating system includes multiple Edge Heatings
The embodiment of device monomer.
In addition, in the present embodiment, middle part target temperature T1 can be set to 150~550 DEG C, edge target temperature T2
Can be set to 180~550 DEG C, to plate width be 80~600mm, with a thickness of 0.5~10mm magnesium alloy board carry out induction plus
Heat.
