The Reason of the Tungsten Heater Large Loss in the Aluminizing Process ——Breaking

If the tungsten heater loss is large, it would cause a lot of waste of material. Because that the breaking or aging of heater element would cause aluminum evapotranspiration incomplete, thus affecting the quality of the final product. What’s more due to the frequent breaking of the heater element, the operators have to install and change the heater element constantly, which would increase the workload of the operators and reduce utilization of the equipment, and ultimately affect the entire production.

The reasons for wolfram heater loss generally include breaking, aging and oxidation of the heater element. While heater element is hard, it is also very crisp to break, operators should be careful of it when transport from storage to avoid the impact of foreign objects. The improper or uneven stress of assembly process would lead to break, which requires the operator to be very careful. When assembling the heater element, the force should be uniform, operators can use a torque wrench to install the reagent, and make sure that both ends of the clamp are parallel state. The wolfram heater should be handled gently, it should not be hit with a hard object, so that it would not get any damage. The best way is to solve this problem is to improve the assembly proficiency of operators.

In addition, when heating the heater element, it would have heat expansion, if the heater element is nipped too tight, there is no room for retractable, then high temperature would lead to the increase of length of the heater element, finally, it would bend and has deformation. When the bending last for a long time, the heater element would break, such breakage is generally called as intermediate fracture. However, if the fixture does not tighten heater, the effective power would loss too much, thus affecting the evaporation effect. Operators can add spring on the fixture to solve this problem.
