摘要： The subject of this invention relates to method carburizing of steel products, mainly parts of machines, vehicles and every mechanical apparatus, in vacuum furnaces under reduced pressure and elevated temperature. The method of under-pressure carburizing of steel workpieces according to present invention relates to introduction of active nitrogen carrier during heating up of the load. Introduction of the active nitrogen carrier is terminated when the load reaches temperature required to start carburizing process; from this temperature the carbon carrier is added. Pressure in the furnace chamber during continuous or pulse introduction of the active nitrogen carrier should be maintained within the ranges from 1 to 500 mbar.

摘要： Device for individual quenching of gears, pinions, bearing rings and other similar components of technical devices, operating in a vacuum furnace installation, whereby the quenching chamber of the installation is fitted with tightly-sealed doors for workpiece loading and unloading. The following elements are fitted inside the quenching chamber: removable table on which an individual workpiece is placed, along with a surrounding set of removable nozzles; the inlet of the quenching chamber features an attached tank supplying the cooling medium to the nozzles—preferably air or nitrogen, or argon or helium, or hydrogen or carbon dioxide, or mixtures thereof—while the outlet of the quenching chamber is connected to the inlet of a tank receiving expanded cooling medium from the chamber; moreover, there is a compressor connected in between the two tanks, ensuring closed-loop flow of the cooling medium.

摘要： A method to generate a ternary carburizing gas mixture, using a reaction of selective hydrogenation of acetylene in a stream of hydrocarbons to the form of ethylene, comprising the following steps: heating of the inside of the reactor with an inert gas to an operating temperature for a period of 20 minutes at a temperature of 300° K, passing a mixture of hydrogen and acetylene by the regiospecific catalyst, and moving out the reaction products on the outside after passing the mixture through the regiospecific catalyst, but generation is effected in a continuous mode in the operating temperature range of the regiospecific catalyst between 293° K and 398° K, preferably at a temperature of 350° K.

摘要： Multi-chamber furnace for vacuum carburizing and quenching of gears, shafts, rings and similar components has at least two process chambers connected in parallel, with a continuous feeding mechanism for individual workpieces. Those chambers—the first one being a heating chamber, the second being a carburizing chamber and the third one diffusion chamber—are configured in a vertical arrangement, placed in a shared vacuum space with gas-tight division, whereas at the ends of each chamber there are incorporated heating chambers with thermal insulation, with a graphite heating system and stepping feeding mechanism incorporated in the core for the purpose of continuous feeding of individual workpieces. At the ends of those chambers the construction incorporates transport chambers featuring loading and unloading systems X-Y enabling cooperation with individual process chambers through thermal and gas-tight doors installed in chamber ends, while external access to the transport chambers is ensured through loading and unloading locks.
