Vacuum arc melting furnace

Brief Description:

Vacuum arc melting furnaces are mainly used by colleges, universities, and scientific research institutions to melt small amounts (tens to hundreds of grams) of precious metals, alloy materials, high-melting-point materials, and refractory metals under vacuum or protective atmosphere. Arc discharge is used to heat and melt the metal raw materials to form alloys.

Equipment Principle

Vacuum arc melting furnace , also called vacuum non-consumable arc melting furnace, button furnace, etc., is suitable for scientific research and development of new materials.

Arc melting is an electrothermal metallurgical process that uses electrical energy to generate an arc between electrodes, or between an electrode and the material being melted, to melt metals. The arc can be generated using either direct current (DC) or alternating current (AC). When using AC, a momentary zero voltage occurs between the two electrodes. In vacuum melting, the low gas density between the electrodes can easily cause the arc to extinguish, so DC power is generally used. It is primarily used to melt active and high-melting-point metals such as titanium, zirconium, molybdenum, tantalum, and niobium, as well as their alloys. It is also used to melt alloy steels such as heat-resistant steel, stainless steel, tool steel, and bearing steel. The resulting metal has reduced gas and volatile impurity levels, resulting in a more uniform crystal structure and improved metal properties, while the ingot generally exhibits less central porosity.
