Title:
ACETYLENE CARBURIZATION FURNACE UNDER NORMAL PRESSURE
Document Type and Number:
Japanese Patent JP2018204101
Kind Code:
A
Abstract:
To provide an acetylene carburization furnace that uses acetylene under normal pressure, can increase use efficiency of facilities to save use costs, and can accurately control an enrichment rate in the furnace.SOLUTION: An acetylene carburization furnace has a control metering device 5 mounted in an acetylene suction duct, an exhaust gas measuring device mounted in an exhaust gas duct, and a computer controller 6 connected to the control metering device and exhaust gas measuring device. After a set temperature is reached in a reaction chamber, the control metering device is actuated based upon parameters, and the reaction chamber is filled with acetylene. The control metering device and exhaust gas measuring device transmit acetylene data and exhaust gas measurement data to the computer controller in real time, respectively, so as to calculate a total carbon atom amount in the furnace and an enrichment rate of a work and then adjust an acetylene suction amount based upon the calculation result until process requirements are met.SELECTED DRAWING: Figure 1
