Background
In the field of rotary targets for coating, particularly ceramic targets or high-temperature alloy targets, target tubes of the targets are spliced and bound (bonded) on a stainless steel liner tube, and the bonded materials are alloys such as indium tin with low melting point. The working principle is that the liner tube is heated to reach the melting temperature of the welding flux, then the welding flux is poured into the gap between the liner tube and the target tube, and the bonding effect is achieved by cooling. In order to improve the bonding strength, the heating is required to be very uniform, and the temperature difference between the upper temperature and the lower temperature is within 5 ℃. According to the conventional heating rod, due to the fact that the cold ends are arranged at the two ends of the heating pipe, heat dissipation at the two ends is fast, the temperature at the two ends is lower than that in the middle by more than 20 ℃, and the technical requirement cannot be met.

Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1 to 3, an isothermal alloy heating rod of the present invention includes a cylindrical heating rod 10 made of aluminum alloy. One end of the heating rod 10 is provided with a temperature sensor (not shown), the temperature sensor is connected with a temperature control cabinet (not shown), and the heating rod 10 is connected with the temperature control cabinet through a power cord 11. 3 through accommodating holes (not shown) are arranged in the heating rod 10 along the length direction, an electric heating pipe 12 is arranged in each accommodating hole, and the electric heating pipes 12 are electrically connected with the temperature control cabinet. The three receiving holes are arranged circularly symmetrically so that they are spaced at the same distance from the axis of the heating rod 10 and at the same distance from each other. The above structure allows the electric heating tube 12 to be heated, and the heat is transferred through the heating rod 10 to heat the bonded material.
In order to avoid cold ends, the two ends of the electric heating tube 12 are high power sections 14, and a low power section 16 is disposed between the two high power sections 14, the power per unit length (i.e. the sum of the total power of the electric heating tube 12 within one meter) of the high power section 14 is 10-20% higher than that of the low power section 16, and the length of the high power section 14 is 30-50%, especially 50% of that of the low power section 16.
Further, the electric heating tube 12 is equal in length to the heating rod 10; a stainless steel cylindrical sleeve (not shown) is disposed outside the electric heating tube 12, and a gap between an outer wall of the sleeve and an inner wall of the receiving hole is 0.1 to 0.15 mm. These measures make the heating of the heating rod 10 by the electric heating tube 12 more uniform.
Further, a hook 18 is provided at one end of the heating rod 10.
Furthermore, the power of the low-power section 16 per unit length is 2-4 kilowatts/meter.
The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
