摘要： An apparatus for sealing a fan drive shaft in a vacuum heat treating furnace is disclosed. The sealing apparatus includes a housing having an annular body and a central opening. An inflatable first seal surrounds the central opening of the annular body. A second seal surrounds the central opening and is adjacent to the inflatable first seal. The sealing apparatus also includes a channel formed in the annular body adjacent to the second seal for conducting a purging fluid into the central opening. A means for injecting the purging fluid into the central opening is operably connected to the channel. A vacuum heat treating furnace and a fan drive system incorporating the sealing apparatus are also described.

摘要： For regulating process gases for heat treatments of metal materials/workpieces in industrial furnaces (1), which have at least one treatment chamber (2), at least one burnoff point (4) having at least one first valve (4.1), and a regulator (5) having pressure meter (5.1), the burnoff point (4) is only to be opened as a function of requirements related to the process gas. For this purpose, in a first step, with open first valve (4.1), a quantity of a flushing gas (6.1) of the gas mixture (6) of the respective process gas is supplied in a controlled manner to the industrial furnace (1) and then burned off, in a second step, the valve (4.1) is closed, the industrial furnace (1) is regulated to a preset furnace pressure and this is permanently detected via the pressure meter (5.1), in a third step, with the target pressure of the industrial furnace achieved, this pressure is detected via the pressure meter (5.1) and maintained, the first valve (4.1) further remaining closed. In a fourth step, the flushing gasification can be activated and adjusted. In the event of large pressure rise, in a fifth step, an overpressure flap (4.3) of the burnoff point (4) can be opened in a controlled manner via a fixed limiting value for pressure dissipation.

摘要： A process for quenching heat treated metal parts using a liquid quenchant and high pressure is disclosed. In general, the process includes the steps of providing a load of heat treated metal parts in a pressure vessel wherein the load is at an elevated temperature after being heat treated. In a subsequent step, a liquid quenchant is injected into the pressure vessel such that a vapor of the liquid quenchant forms rapidly in the pressure vessel and cools the metal parts. The step of injecting the liquid quenchant into the pressure vessel is continued for a time sufficient to establish a desired peak vapor pressure in the pressure vessel. An apparatus for carrying out the disclosed process is also described.
