Embodiment

[0043] Assuming that the geometric size of the magnesium alloy plate to be rolled is 1600×4mm, the traveling speed is 1000mm / min, and the temperature is increased from 100°C to 220°C after passing through the online heating device, the design and use method of the present invention will be described below through specific equipment specifications and operating steps .

[0044] The induction device adopts a thyristor-type medium-frequency induction heating device, the inverter model is GPS / 500 / 1S, and it is cooled by water cooling with a pressure of 0.1-0.2 MPa. The inductor adopts a flat multi-layer type and adds a magnetic yoke device inside it. figure 2 , The geometrical size of the sensor is 1900*750*400, and the maximum power of the power supply is 800kW. The induction heating furnace body adopts 20mm phenolic glass silk board without magnetism, and there is a hook device on it. Two screw rods with a diameter of 40mm are connected to the top of the box, and a motor is use...

Abstract

The invention discloses an online strip heating device for magnesium alloy rolling, which includes an induction heating device, a gas heating device, and an infrared thermometer installed at the entrance and exit of the magnesium alloy rolling, and the infrared thermometer is used for real-time monitoring The magnesium alloy online temperature is connected with the control system of the induction heating device and the gas heating device, and the whole heating system is closed-loop controlled by setting the target temperature. The induction heating device adopts the medium frequency induction heating method, including the frequency conversion device, the induction heating furnace body and Furnace front control device; gas heating device includes combustion chamber, ignition electrode, ignition control system and gas distribution cylinder. The furnace body heated by induction and the combustion chamber heated by gas are distributed up and down, and the magnesium alloy strip to be rolled passes through the two And enter the rolls for rolling. The invention can quickly and efficiently control the temperature of the magnesium alloy within the optimum rolling temperature range, and at the same time can improve the temperature uniformity of the magnesium alloy strip to be rolled, so as to achieve the purpose of shape control.

Description

technical field [0001] The invention relates to processing equipment for magnesium alloy sheet rolling and forming, in particular to an on-line heating device for strips during magnesium alloy rolling. Background technique [0002] Magnesium alloy is the lightest metal among structural materials. In recent years, it has been gradually applied to fields such as aerospace, national defense and military industry, automobiles, and electronic communications. At the same time, the requirements for its performance and efficiency in these fields are also increasing. Traditional cast magnesium alloys have gradually failed to meet the requirements, and wrought magnesium alloy products produced by extrusion, forging, rolling and other processes have higher strength, better ductility, and more diverse mechanical properties. Among them, rolling, as an important means of plastic processing of magnesium alloys, has been greatly developed. [0003] Magnesium alloy has a close-packed hexago...
