Embodiment 1
[0024] In order to overcome the problems of low space utilization rate of existing circular coils, large energy consumption and low efficiency during use, the present invention provides such Figure 1-7 Shown is a rectangular induction coil of a tungsten-molybdenum sintering furnace. The rectangular induction coil provided by the present invention can increase the utilization rate of the furnace, and has less energy consumption and greater production capacity.
[0025] A rectangular induction coil for a tungsten-molybdenum sintering furnace, comprising a copper tube 1 and a bakelite column 2, the copper tube 1 and the bakelite column 2 form a rectangular induction coil, the inner size of the rectangular induction coil is 4910×1290 mm, and the copper tube 1 Wound into a coil shape through the mold, the coil turn spacing 4 between the coils is 15-50mm; the bakelite column 2 is evenly distributed in the vertical direction on the outer surface of the copper tube 1, and the bakelite...
Embodiment 2
[0040] Based on Example 1, in this example, the pitch of the bakelite columns 2 is 240-560mm.
[0041] Cooling water passes through the copper tube 1 .
[0042] The cooling water quality requirements: water inlet temperature ≤ 25±5°C, pH value between 6-9, resistivity 30×10³Ω.cm, hardness not greater than 10 degrees, wherein 1 liter of water contains 10 mg of oxidation Calcium, the total solid content does not exceed 250mg / L, and the outlet water temperature should be controlled below 45 degrees Celsius.
[0043] The four corners around the rectangular induction coil are rounded.
[0044] The inner dimension of the rectangular induction coil provided by the present invention is 4910×1290 mm, and is composed of a copper pipe 1 and a bakelite column 2 . Copper pipe 1 passes a special mold to make the section into Figure 7 The copper tubing shown is wound into Figure 4 coil shape shown, and guarantees that during winding, Figure 7 The copper tube 1 shown is not deformed. ...
