Description

TECHNICAL FIELD

[0001] The present application relates to the field of non-ferrous metal processing, in particular to a complete set of non-ferrous metal semi-solid extrusion equipment. BACKGROUND

[0002] In the field of molten processing of non-ferrous metals such as magnesium and aluminum, traditional heating methods have exposed many drawbacks in the long-term application. As a common heating means, resistance heating relies on the current passing through the resistance material to generate heat, and then the heat is transferred to the magnesium and aluminum material in the form of heat conduction. However, the heating efficiency of resistance elements such as resistance wires is limited, and there is obvious thermal resistance in the heat conduction process. The heat from the resistance element needs to pass through multiple layers of medium, and each layer of medium will absorb part of the heat, resulting in slow heat transfer, and thus the heating speed of the material is extremely slow. This not only lengthens the entire molten processing cycle, seriously affecting the production efficiency, but also in the long-term heating process, due to the difficulty in achieving absolute uniformity of heat distribution, the heating degree of different parts of the material is different, which is easy to cause local overheating or insufficient heating. This has a great negative impact on the quality stability and performance consistency of magnesium and aluminum alloys. Fuel oil heating also faces many difficulties. In the combustion process of fuel oil, only part of the chemical energy can be effectively converted into heat energy for material heating, and a large amount of energy is wasted in the links of insufficient combustion, exhaust smoke heat dissipation, etc., resulting in a long-term low energy utilization rate. According to relevant data statistics, the energy utilization rate of traditional fuel oil heating equipment is usually only between 30% and 40%. At the same time, fuel oil combustion will release a large amount of waste gas pollutants such as sulfur dioxide, nitrogen oxides, particulate matter, etc. These pollutants not only cause serious pollution to the atmospheric environment, causing environmental problems such as acid rain, haze, etc., but also with the increasingly stringent environmental protection regulations, enterprises need to invest a large amount of funds for waste gas treatment, which undoubtedly greatly increases the production cost. With the continuous rise of the requirements of modern industrial production for high efficiency, energy saving and environmental protection, it is urgent to develop a completely new technology that can effectively overcome the defects of traditional heating methods. As a new heating technology, microwave heating has gradually entered people's field of vision in recent years. The principle of microwave heating is based on the interaction between microwaves and molecules. When microwaves are radiated onto the magnesium and aluminum material, the polar molecules in the material will vibrate and rub at a speed of billions of times per second under the action of the high-frequency alternating electric field of the microwaves, thereby directly converting the microwave energy into heat energy, realizing the rapid heating of the material itself. This heating method has the significant advantages of fast heating speed and good heating uniformity, and can theoretically greatly improve the efficiency and quality of magnesium and aluminum molten processing, and also has great potential in energy utilization. However, in the actual attempt to apply microwave heating technology to magnesium, aluminum melting system, encountered a huge technical bottleneck. Magnesium, aluminum and other metals belong to good conductor, microwave in contact with the metal surface, will follow the electromagnetic principle occurs strong reflection. Most of the microwave energy cannot penetrate the metal surface into the material inside, but is reflected back to the heating device, which makes the microwave energy utilization rate sharply reduced, heating effect greatly discounted. Moreover, the reflection of metal microwave heating area will cause the microwave field distribution is extremely uneven, further exacerbating the unevenness of material heating. To solve this problem, researchers and engineering and technical personnel tried a variety of methods, such as changing the microwave frequency, adjusting the heating device structure, etc., but due to the physical properties of the metal and microwave interaction is more complex, the existing technical means is difficult to fundamentally realize the efficient coupling of microwave and magnesium, aluminum material, which has become a key problem hindering the wide application of microwave heating technology in magnesium, aluminum melting system.
