本文介绍了用液体原料制取的直接式渗碳炉气的应用及其可控性研究结果。采用多相平衡反应的方法计算了四种炉气成分。 研究发现,由于混合比变化造成的炉气成分变化,是引起单参数碳控时炉气碳势波动的重要原因。这种波动的大小反映了炉气可控性的优劣。并发现可以通过选择合适的渗剂、合适的控制参数及恰当的通气量改善其可控性。
This article describes the use of liquid raw materials obtained from the direct carburizing gas applications and controllable research results. Four kinds of furnace gas compositions were calculated by the method of multiphase equilibrium reaction. It is found that the variation of furnace gas composition due to the mixture ratio changes is an important reason for the fluctuation of carbon potential in the furnace gas caused by single-parameter carbon control. The size of this fluctuation reflects the pros and cons of furnace gas controllability. And found that it is possible to improve its controllability by selecting suitable osmotic agents, suitable control parameters and proper ventilation.
