    • In a cementation method of metals in which hydrocarbon gas and oxidization gas are introduced into a heat treatment furnace, a small quantity of hydrocarbon gas of is introduced at a low pressure into the heat treatment furnace. The shift time and the gradient of the carbon potential varying toward a predetermined high or low level are controlled by increasing or decreasing the quantity of cementation gas and oxidization gas to be supplied to the furnace. After the carbon potential is reached to the high or low level, the carbon potential is maintained for a predetermined time period so as to prevent the deposited carbide from being bulked. In order to prevent the gas supply pipe from being choked with the soot of the hydrocarbon, oxidization gas of intermediate pressure is flushed into the gas supply pipe. In order to prevent the components of the atmosphere in the furnace from varying due to the change in furnace pressure when the door is opened or closed, hydrocarbon gas of a low pressure and oxidization gas of an intermediate pressure are added in the conversion pipe in the preheating zone. CO.sub.2 of intermediate pressure is supplied into each gas supply pipe at the same time in order to remove the soot in each of the gas supply pipes and to prevent the lack of CO to be introduced into the furnace.
    • 在其中将烃气体和氧化气体引入热处理炉中的金属的固井方法中,将少量烃气以低压引入到热处理炉中。 通过增加或减少要供给到炉中的胶结气体和氧化气体的量来控制向预定的高或低水平变化的碳势的偏移时间和梯度。 在碳电势达到高电平或低电平后,碳电势保持预定时间段,以防止沉积的碳化物膨胀。 为了防止气体供给管被碳氢化合物的烟灰窒息,将中间压力的氧化气体冲入气体供给管。 为了防止炉门内的气氛成分由于炉门打开或关闭时的炉压变化而变化,低压的烃气和中压的氧化气体被加入到转炉管中 预热区。 中间压力的二氧化碳同时供给到每个气体供给管中,以便除去每个气体供给管中的烟灰,并且防止CO的缺乏被引入炉中。
