炉外精炼技术是冶金技术革新重大发展方向之一,真空氧氩精炼炉(VOD)在炉外精炼系列中占有重要地位,特别是设有付枪装置的精炼炉可在冶炼进行中,在不破坏真空条件下,进行测温,定氧或采样等。这些信息的获得,对掌握冶炼动态,制定合理的精炼工艺,以使 Furnace refining technology is one of the major development directions of metallurgical technology innovation. Vacuum oxy-argon refining furnace (VOD) plays an important role in the refining of the furnace. In particular, the refining furnace equipped with the pay-gun device can be in the process of smelting, Destruction of vacuum conditions, temperature, oxygen or sampling and so on. The acquisition of these information, to master the dynamics of smelting, to develop a reasonable refining process so that
