[0055] As a technical optimization solution of the present invention, the heat dissipation pipe 11 can assist the heating furnace chamber 2 in its operation and play a role in heat dissipation and exhaust, thereby avoiding the phenomenon that the high-temperature gas inside the heating furnace chamber 2 cannot be discharged and causes metal fatigue and collapse.

[0056] refer to Figure 1 The front end and the back end of the heating furnace cavity 2 are both laterally fixedly connected with reinforcing ribs 12, and the reinforcing ribs 12 are used in conjunction with the heating furnace cavity 2.

[0058] refer to Figure 5 The front end and the back end of the placement plate 509 are both provided with limiting grooves 13 , and the limiting grooves 13 are used in conjunction with the placement plate 509 .

[0059] As a technical optimization solution of the present invention, the setting of the limiting groove 13 can assist the silicon carbon rod body 511 in working, thereby avoiding the phenomenon that the silicon carbon rod body 511 rolls off due to the flat surface of the placement plate 509.

[0060] The working principle and use process of the present invention are as follows: when in use, the silicon carbon rod body 511 is placed on the surface of the placement plate 509, and then the servo motor 502 is started. The servo motor 502 drives the gear 503 to rotate clockwise, and the rotation of the gear 503 drives the synchronous wheel 506 to rotate accordingly. The rotation of the synchronous wheel 506 drives the rotating rod 504 and the worm 505 to rotate synchronously. During the rotation of the rotating rod 504, the L-shaped clamping sleeve 8 is used to steadily maintain the stability of both ends of the rotating rod 504. Then the worm 505 rotates and cooperates with the staggered threads to drive the worm wheel 507 to rotate. The worm wheel 507 rotates to move the tooth plate 510 to the left. The tooth plate 510 moves to the left and drives the placement plate 509 and the silicon carbon rod body 511 to follow the movement. When the placement plate 509 moves to the left, it cooperates with the roller 508 to support the bottom to reduce the movement friction, and cooperates with the clamping plate 10 to press against the placement plate 509 to prevent the movement direction from deviating. Finally, the placement plate 5 09 drives the silicon carbon rod body 511 to penetrate into the heating furnace cavity 2 for heating treatment. When the silicon carbon rod body 511 enters the heating furnace cavity 2, the motor 62 is started to work. The output end of the motor 62 rotates to drive the first pulley 63 to rotate. The first pulley 63 rotates clockwise to drive the belt 67 and the second pulley 66 to rotate. The second pulley 66 rotates to drive the output shaft 64 to rotate. The output shaft 64 rotates at a high speed to drive the axial flow fan 65 to work and blow the airflow to circulate inside the heating furnace cavity 2, so that the airflow movement takes away the heat and is discharged from the inside of the heating furnace cavity 2 through the heat dissipation pipe 11 to complete the heat dissipation. Finally, the surface of the silicon carbon rod body 511 is sprayed with a high-temperature anti-oxidation coating 71 and an antibacterial coating 72. This coating can improve the high temperature resistance of the silicon carbon rod body 511, and can also prevent harmful gases and substances from eroding the silicon carbon rod body 511 to a certain extent, thereby indirectly playing an antibacterial and anti-corrosion role.

[0061] To sum up: the heating furnace for producing W-type silicon carbon rods and the method of using the same, through the base plate 1, the heating furnace chamber 2, the fixing box 3, the bracket 4, the driving mechanism 5, the support plate 501, the servo motor 502, the gear 503, the rotating rod 504, the worm 505, the synchronous wheel 506, the worm wheel 507, the roller 508, the placement plate 509, the tooth plate 510, the silicon carbon rod body 511, the heat dissipation mechanism 6, the base 61, the motor 62, the first pulley 63, the output shaft 64, the axial flow fan 65, the second pulley 66, the belt 67 and the material component 7, the use of the same solves the problem that the existing W-type silicon carbon rod heating process requires the operator to carry the material to the heating furnace, which is time-consuming and labor-intensive.

When the placement plate (509) moves to the left, it cooperates with the roller (508) to support the bottom to reduce the movement friction. Finally, the placement plate (509) drives the silicon carbon rod body (511) to go deep into the heating furnace chamber (2) for heating treatment, and executes S2; S2; When the silicon carbon rod body (511) enters the interior of the heating furnace chamber (2) and the motor (62) is started, the output end of the motor (62) rotates to drive the first pulley (63) to rotate accordingly, the first pulley (63) rotates clockwise to drive the belt (67) and the second pulley (66) to rotate accordingly, the second pulley (66) rotates to drive the output shaft (64) to rotate, the output shaft (64) rotates at a high speed to drive the axial flow fan (65) to work and blow air to circulate inside the heating furnace chamber (2), so that the air flow moves to take away the heat and discharge it from the interior of the heating furnace chamber (2), thereby completing the heat dissipation.
