【摘要】 <正>电弧定碳炉源于我国,已有十六年历史。现在自制的商品仪器中高频高压引燃炉较之低频低压和工频高压引燃炉具有激发能量大的优点,但其引燃率受试样形状、粒度和钢种的影响还不能达到百分之百,手动调节弧距也给操作带来不便。 作者提出连续电弧自动跟踪试样燃烧炉,它具有电弧不断、自动调节弧距、自动更多还原

【Abstract】 A continuous arc automatic following furnace has been proposed in this paper. Advantages of this furnace are:self regulation of the arc length; follow specimen automatically; being unaffected by the difference in shape or grain size of sample; without addition of accelerator; high tem-’perature and achieving a perfect sparking rate etc. It can be connected with various types of other instruments for determine carbon and sulphur and with safety in operation.更多还原
