Description

Technical Field

[0001] The utility model relates to the technical field of casting processing, in particular to a casting production line. Background Art

[0002] Ingot molds are made by pouring molten metal into permanent or reusable molds. After solidification, these ingots (or bars, slabs or billets depending on the container) are further machined into a variety of new shapes. Ingot molds are generally set on the casting production line and move with the conveyor line of the casting production line.

[0003] If the ingot mold (referred to as: mold) directly contacts high-temperature aluminum liquid of about 720°C without residual heat, it is easy for the bottom of the mold to expand and contract due to rapid heating until tiny cracks appear. When the cracks extend to the outer shell of the mold and water seepage occurs, the high-temperature aluminum liquid flows into the mold and encounters water, which can easily cause a molten metal explosion accident.

It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following text, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0023] like Figure 1 As shown, a casting production line provided in this embodiment includes a conveyor line 24 , an ingot mold 27 and a heating device 28 arranged on the conveyor line 24 .

[0024] The heating device 28 includes a heating mechanism 3 installed beside the conveyor line 24 and close to the ingot mold 27, and a fuel station 1 located outside the conveyor line 24. The fuel station 1 and the heating mechanism 3 are connected through a first pipeline 2. The first pipeline 2 is provided with an ignition line and a fire detection line, and ignition is performed through the ignition line.

[0025] like Figure 2 As shown, the fuel station 1 is provided with a control system 4, a gas distribution system 5, an air distribution system 6 and a leakage detection system 7. The gas distribution system 5, the air distribution system 6 and the leakage detection system 7 are respectively electrically connected to the control system 4. The entire heating device 28 is controlled by the control system 4 to realize the automatic ignition and gas leakage alarm functions.

[0026] like Figure 3 As shown, the gas distribution system 5 includes a filter 11, a safety solenoid valve 12, a pressure reducing valve 13, a combustion solenoid valve 14 and a proportional valve 15 which are sequentially connected through a second pipeline 19. One end of the second pipeline 19 provided with the filter 11 is connected to a natural gas source 16, and the other end of the second pipeline 19 is connected to the first pipeline 2. A first pressure gauge 17 is also provided on the second pipeline 19, and the first pressure gauge 17 is located between the natural gas source 16 and the filter 11.

[0027] like Figure 2 As shown, the air distribution system 6 includes a fan 21 and a third pipeline 20, one end of the third pipeline 20 is connected to the fan 21, and the other end of the third pipeline 20 is connected to the first pipeline 2. The third pipeline 20 is connected to a second pressure gauge 22 and a wind valve 23.

[0028] The leakage detection system 7 is electrically connected to the control system 4 .

[0029] like Figure 4As shown, the heating mechanism 3 includes a fourth pipeline 26, a cover shell 8 and a heater 10 arranged in the cover shell 8, one end of the fourth pipeline 26 extends into the cover shell 8 and communicates with one end of the heater 10, and the other end of the fourth pipeline 26 forms a heating port 25, and the heating port 25 is arranged toward the ingot mold 27.
