摘要： An industrial furnace for heat-treating metallic workpieces has separate heating and cooling chambers. The latter uses a circulating cooling gas, the flow of which against or past the workpieces produces cooling or gas-quenching. The furnace may have another chamber for oil-quenching lying below the gas-cooling chamber. In order to enable the gas cooling to operate quickly and efficiently, a cooling box fed with air by ventilator fans is provided in the shape of a tunnel, with internal surfaces above and at both sides of the effective cooling space constituted by interchangeable nozzle plates (or blank plates if no nozzle openings are desired at the top or at the sides). The workpieces to be cooled rest on a platform which may be raised or lowered to adjust the distance from the top nozzle plate or lowered into an oil bath. The nozzle plates provide a choice of nozzle patterns for different articles or groups of articles to be cooled after heat treatment. The nozzle plates may have setbacks or protrusions in order to vary the spacing of the nozzle openings from the median plane of the cooling tunnel.

摘要： A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. The workpieces are positioned in an air-tight washing vessel. The vessel is filled with an immersion bath substantially covering the workpieces and having a temperature of between 50.degree. C. and 90.degree. C. After closing the washing vessel it is evacuated down to a vacuum having a pressure being below the saturation vapor pressure of the fluid at the prevailing temperature. Thus, the fluid starts to boil although its temperature is substantially below the boiling temperature of the fluid at atmospheric pressure. After a certain period of time of maintaining the vacuum and the boiling, the vacuum is relieved and the bath is discharged.

摘要： A method and an apparatus serve for drying industrial barrels (60). The industrial barrels (60) are positioned on an inclined base (12, 20) and are enclosed by a pressure-tight vacuum hood (30). A suction pipe (40) that is connected with the vacuum hood (30) extends through a bunghole (63) provided in the tilted barrel (60) at its lowest point (71) where the residual liquid quantity (70) gathers. A heating rod (55) is arranged inside the suction pipe (40). The suction pipe (40) is connected to a vacuum pump (48). The heated suction pipe (40) removes from the interior of the barrel (60) at first die liquid residual liquid quantity (70), and then the vaporizing residual liquid. Compared with conventional methods, using hot steam for drying, this method leads to cost savings and an improved drying effect (FIG. 1 ).

摘要： A burner for an industrial furnace has a plurality of lines passing through a furnace wall for fuel gas, burner air, and waste gas. Arranged in the furnace space is a combustion chamber (66) in which a mixture of fuel gas and burner air is combusted, and from which a flame (89) is directed into the furnace space. The combustion chamber (66) is delimited by walls (32, 65). The walls (32, 65) are arranged to be movable with respect to one another (65', 65"), so that the volume of the combustion chamber (66) is adjustable (FIG. 2).

摘要： In order to permit operation with preheating of the combustion-supporting air to 50 or preferably 65 percent or more of the oven temperature, the air is fed to a ceramic burner tube through an annular nozzle directing it in an annular jet along the interior walls of the burner tube. For a burner of low back pressure having no restriction at the mouth of the ceramic burner tube, the ceramic burner tube fits over the end of the outer member of the annular nozzle and some of the combustion product gas, flowing from the oven into the burner structure for countercurrent of the preheating of the air supply, is sucked into the underpressure zone between the annular air jet and the inner wall of the burner tube through a small annular gap where the burner tube fits on the air-supply nozzle. For a burner design involving considerable back pressure, the ceramic burner tube fits within the outer wall of the annular nozzle with a very small clearance in the overlap and some of the supplied air, which is at higher pressure than the exit in gases, escapes through the gap around the outside of the burner tube and cools the burner tube and the adjacent overlapping portion of the air supply tube.

摘要： A method and an apparatus for treating workpieces with a fluid, in particular for cleaning metallic workpieces prior to a subsequent heat treatment are disclosed. According to claimed method the workpieces are positioned in a washing vessel and are entirely overflowed with a pressureless swell of a treating fluid. After a certain period of time, a discharge opening in the vessel is closed so that an immersion bath is filled in. When the workpieces are entirely immersed in the treating fluid, the fluid is agitated by means of air bubbles. During subsequent bath discharge the workpieces are continuously overflowed by the treating fluid in order to avoid chemical reactions with the ambient atmosphere. Finally, the workpieces are dried by means of a vacuum dryer.
