在某一选定的加热温度下进行热处理时,不论是含0.1％碳的钢,或是高至碳饱和的奥氏体钢,都可能需要一种与钢的含碳量相平衡的炉气。对存在于炉气中那些能产生渗碳或脱碳作用的成分含量如果不能进行分析或控制,那就难以控制钢的含碳量。要对炉气进行分析,首先必须能取得有代表性的炉气试样。 Heat treatment at a selected heating temperature, whether steel containing 0.1% carbon or austenitic steel up to carbon saturation, may require a furnace gas that is balanced with the carbon content of the steel . It is difficult to control the carbon content of steel if it is impossible to carry out the analysis or control of the contents of the components present in the furnace gas which can produce carburization or decarburization. To analyze the furnace gas, you must first be able to obtain a representative furnace gas sample.
