Technical Field
The invention belongs to the technical field of thermal resistors, and particularly relates to a production system and a production process of an armored thermal resistor.
Background
At present, the traditional armored thermal resistor is manufactured by cold-drawing the combination of a metal sleeve, an insulating material and a thermocouple wire. The metal sleeve is generally made of stainless steel or nickel-based high-temperature alloy, and has good oxidation resistance and corrosion resistance at the temperature of below 1100 ℃. Because the metal sleeve has only one layer, under some severe environments with high-temperature corrosion, the service life of the traditional single-layer armored thermal resistor is short, and cost control and efficiency improvement are not facilitated. Therefore, some enterprises develop the armored thermal resistor with double-layer metal sleeves, and then sleeve an outer layer metal sleeve outside the original single-layer armored thermal resistor, and then cold-draw or cold-forge the outer layer metal sleeve and the inner layer metal sleeve tightly, and the outer layer metal sleeve is generally made of nickel-based high-temperature alloy material suitable for cold machining. However, for some extremely severe high-temperature corrosion environments, the service life of the double-layer armored thermal resistor is superior to that of the traditional armored thermal resistor, but the industrial production requirement under the extremely severe high-temperature corrosion environments cannot be met.
When an insulating layer is attached to the surface of the thermal resistor, the surface of the resistor is wrapped by plasticizing a raw material through an extruder, in order to ensure that the surface of the resistor is fully contacted with the raw material, the resistor is generally introduced into a tee joint head for surface coating treatment, but the tee joint head has a small volume, the plasticized raw material is easily solidified on the inner wall of the tee joint head, the service life of the tee joint head is short, and the cleaning of the interior of the tee joint head is particularly troublesome.
