Background technology
Magnesium alloy plate is the structured material of a kind of lightweight, has been widely used the fields such as aerospace, defence and military, automobile, telecommunications in recent years. But magnesium alloy has the shortcoming of plasticity difference at normal temperatures, the rolling technology of traditional steel plate/aluminium sheet is therefore adopted to be difficult to roll high-quality magnesium alloy plate.
By the Research of Rolling Process of magnesium alloy materials being shown, rolling temperature controls when 225-400 DEG C, and roll reduction can reach 87.5% and crackle do not occur, and rolling temperature below 200 DEG C time, then crackle easily occurs. Magnesium alloy is again the metal of oxidizable burning simultaneously, and when in the operation of rolling, magnesium alloy temperature is too high, the oxidizing reaction of magnesium alloy can be accelerated, it is easy to causes magnesium alloy burning, and grain structure becomes big, and mechanical property is deteriorated. Therefore, in magnesium alloy rolling process, the temperature of magnesium alloy generally to be controlled within 220-400 DEG C.
But roll of the prior art does not have the ability regulating magnesium alloy temperature in the operation of rolling, before the rolling, roller temperature is lower, and magnesium alloy plate is met low temperature roll and easily produced rolling crack; And in the operation of rolling, after roller temperature rises, particularly when rolled sheet metal and rolling reduction are bigger, roll can not take away the high heat produced in the operation of rolling timely, this easily cause again magnesium alloy plate to occur burning, crystal grain become problem big, mechanical properties decrease.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of roll preheating insulation system, the problem of magnesium alloy plate temperature in rolling technology claimed range can not be ensured in the operation of rolling to solve tradition roll.

Accompanying drawing explanation
Fig. 1 is the structural representation of roll preheating insulation system of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure, the present embodiment roll preheating insulation system, comprise storage tank 1, recycle pump 2, well heater 3, water cooler 4, upper roll 5, bottom roll 6 and controller 7, described upper roll 5 and bottom roll 6 inside are provided with oil chamber, and upper roll 5 is provided with the two ends of bottom roll 6 and enters oily swivel joint and fuel-displaced swivel joint with oil chamber is connected;
The oil outlet of described storage tank 1 is connected by the oil-in of pipeline with recycle pump 2, the oil outlet of described recycle pump 2 is connected by the oil-in of pipeline with well heater 3, the oil outlet of described well heater 3 is connected by the oil-in of pipeline with water cooler 4, the oil outlet of described water cooler 4 is connected with the oil swivel joint that enters of bottom roll 6 with upper roll 5 respectively by pipeline, and described upper roll 5 is connected by the oil-in of pipeline with recycle pump 2 with the fuel-displaced swivel joint of bottom roll 6;
The oil-in pipeline of described well heater 3 is provided with temperature sensor 8, the signal input terminus electrical connection of the signal output terminal of described temperature sensor 8 and controller 7, the signal output terminal of described controller 7 respectively signal input terminus with well heater 3 and water cooler 4 be electrically connected.
The mode of operation of the present embodiment roll preheating insulation system is:
Before the rolling, oil in storage tank 1 is recycled pump 2 and pumps and circulate along pipeline, controller 7 controls the temperature that oil is heated to processing requirement by well heater 3, hot oil enters roll 5 and roll is preheating to the temperature that technique specifies by bottom roll 6, thus when can prevent rolling, magnesium alloy plate heat is siphoned away by low temperature roll and produces the problem of rolling crack.
In the operation of rolling, by monitoring well heater 3 oil outlet oil temperature during temperature sensor 8, when temperature is higher than design temperature, controller 7 just controlled cooling model device 4 hot oil is lowered the temperature, when temperature oil temperature is lower than design temperature, controller 7 just controls well heater 3 and hot oil is carried out heat temperature raising, thus adjustable roller temperature remains within the scope of processing requirement, to avoid, roller temperature is too high can not take away the high heat produced in the operation of rolling timely, cause magnesium alloy plate that burning occurs, crystal grain becomes big, the problem of mechanical properties decrease, and avoid because roll middle portion temperature is low, cause rolled piece temperature to be siphoned away by roll and the problem of rolling crack occurs.
As the improvement to the present embodiment, the oil outlet pipeline of described well heater 3 is provided with pressure transmitter 9, the signal output terminal of described pressure transmitter 9 and the signal input terminus electrical connection of controller 7. The oil pressure of roll oil-in side is monitored constantly by pressure transmitter 9, when the oil pressure is low, by controller 7 or Artificial Control storage tank 1 oil outlet valve opening to system repairing, the problem of oil is lacked with resolution system, when oil pressure raises, by pressure relief valve 10 pressure release being arranged in oil circulation pipe, raise the problem that tubing system is produced infringement with resolution system oil pressure.
