随着冶金工艺的不断更新,冶炼的速度日益提高,因此对炉前分析要求有一个与相适应的跃进,在“准”的前提下,对“快”提出以秒钟计的更高要求。在这种情况下,化学分析己逐渐地感到难以胜任。至六十年代,直读光谱仪的问世,使炉前分析进入一个新的领域,而后又相继采用了高速光源、风动送样、高速试样制备装置等新工艺,使 With the continuous updating of the metallurgy process and the increasing speed of smelting, there is a leap forward compatible with the requirements of the furnace front analysis. Under the premise of “quasi”, higher requirements of “quick” are set forth in seconds. In this case, chemical analysis has gradually become less competent. By the 1960s, the advent of direct reading spectrometers enabled furnace front analysis to enter a new field, followed by new technologies such as high-speed light sources, pneumatic feed, high-speed sample preparation,
