Process and apparatus for producing atmospheres for high productivity carburizing |
摘要 |
This invention is directed to a process and apparatus for producing high productivity carburizing. A process is introduced that uses a gas mixture made up of CO, H2, CO2, H2O, CH4 and N2, such that the product of the % CO and % H2 is greater than about 1600; the ratio of CO/CO2 is greater than 10; and the ratio of H2/H2O is greater than about 10. The gas mixture is controlled for a short time. A reactor for generating a gas mixture for carburizing steel is also introduced. This reactor is composed of a cylindrically symmetric body; a first central tube containing electrical heating elements for gas flow; a second central tube concentrically disposed around the first central tube; and a plurality of catalyst beds disposed in an annular space in a segmented fashion around the second central tube.
