Abstract

Finishing machine for heat treatment of steel workpieces including the workpiece Cold steel and hot steel workpieces The finished machine is a type that consists of Heat treatment furnace for steel workpieces through the heat treatment process. heated room For preheating the cold steel workpiece before the cold steel workpiece is fed into the heat treatment furnace. The heated chamber is connected to the heat bath to receive the wasted heat from the heat bath. for the preheating process and there is an outlet section for pushing out the cold steel workpiece; The heat bath has a heating zone for heating the steel workpiece, a heat bath area adjacent to the heating zone and a heat source for heating the heated steel workpiece within the heating zone. already heated at temperatures higher than the temperature of the heating area For the heat treatment process, the heat bath area has a ceiling higher than the ceiling of the heating area and has a device for connecting the heating area to the heated room. to feed wasted heat into the heated room

Claims (3)

1. Finishing machines for heat treatment of steel workpieces including cold steel workpieces and hot steel workpieces. The finished machine is a type that consists of Heat treatment furnace for steel workpieces Through the process of bathing heat The preheating chamber is used to heat the cold steel workpiece before the cold steel workpiece is fed into the heating furnace.The heated chamber is connected to the heat bath to receive the waste heat from the furnace. A heat bath for preheating processes and an outlet for removing cold steel workpieces. And there is a device for feeding the steel workpiece into the heat treatment furnace and moving the steel work piece through the heat treatment furnace. Improvements related to heating stoves Which includes (a) a heating room with a first ceiling The first side wall And one end with an inlet for steel workpieces. (B) The heat bath is integrated with the heating chamber. The thermal bath is connected to the heating chamber so that the heat energy is fed from the thermal bath to the heating chamber. And so that the steel workpiece can be moved from the heating chamber to the heat bath Thermal baths have a second ceiling. The second side wall is equipped with a heat device for heating steel workpieces and There is an outlet that is assembled at one end of the heating chamber away from the heating chamber for the removal of the steel workpiece.The heating chamber is aligned with the heating chamber along the path. Of the movement of steel workpieces from the inlet of the heating chamber to the outlet of the heating room (c) a device for connecting one end of the heating chamber to the outlet portion of the heating chamber Heat To feed the heat from the heating room to the heated room. And where the heating room is assembled into the room area One, which has a heating device installed on the upper part of the second side wall, one wall of the heating room. The second ceiling of the heating chamber is higher than the first ceiling of the heating chamber. Where radiant heat is produced near the second ceiling within the heating room when the heating device is operating. Therefore, most of the heat treatment is radiant heat to the steel workpiece that has been heated in the heating chamber mainly by conduction. This is because the heat energy being fed from the heating room is higher than that of the heating chamber. 2. Apparatus for heating steel workpieces as described in Clause 1, where the furnace is installed perpendicular to the heated chamber. Compared with the path of movement of steel workpieces And where the equipment Connected as a pipe for feeding the heat loss from the heating area to the heated room. 3. The apparatus for heat treatment of steel parts as described in Clause 1, where the connection device is a pipe with a built-in valve to open and close the pipe.
