Description

Technical Field

[0001] The utility model relates to a high-nitrogen and low-nickel stainless steel ultrasonic stirring medium-frequency induction furnace, belonging to the field of alloy processing. Background Art

[0002] Stainless steel is an iron-based alloy. It is mainly composed of iron, chromium, nickel and other elements, and usually contains a small amount of carbon, manganese and other elements. High nitrogen low nickel stainless steel is a special type of stainless steel alloy with a higher nitrogen content and a lower nickel content than other stainless steels. This type of stainless steel usually contains a higher nitrogen content, which is very beneficial to improving the strength and corrosion resistance of the alloy. At the same time, due to the lower nickel content, this stainless steel can be used in some specific cost-sensitive applications. A medium frequency induction furnace is a common alloy processing equipment. It generates an alternating magnetic field through a coil and transmits electrical energy to the alloy inside the workpiece, thereby generating eddy currents inside the alloy and generating heat through the resistance of the alloy. It has been widely used in the field of alloy processing due to its efficient heating, precise control and wide applicability. However, when processing high-nitrogen, low-nickel stainless steel, in addition to using a medium frequency induction furnace for processing, it is also necessary to combine the process of ultrasonic vibration technology for heating. The purpose is to improve the metal uniformity of high-nitrogen, low-nickel stainless steel under the action of ultrasonic waves during the processing process, so that high-nitrogen, low-nickel stainless steel can be processed evenly. In existing conventional stainless steel medium frequency induction furnaces, the devices for realizing ultrasonic stirring, such as ultrasonic conductors, transducers, ultrasonic probes, etc., are mostly fixed, and cannot be adjusted according to the actual metal smelting liquid level. The outlet of the medium frequency induction furnace is also mostly exposed, which results in the metal located in the center of the medium frequency induction furnace being not conducive to eliminating gas inclusions and low uniformity of the melt.

[0003] Therefore, it is urgent to propose a new type of high-nitrogen and low-nickel stainless steel ultrasonic stirring medium-frequency induction furnace to solve the above technical problems. Utility Model Content
