AI Technical Summary

Technical Problem

During the high-temperature heat treatment process, existing energy-concentrating pot racks are prone to deform due to the expansion of air in the internal cavity, which affects the formation of the protective layer and leads to a decrease in production pass rate.

Method used

A through hole is opened on the energy-concentrating pot rack body, connecting the cavity between the upper and lower covers, applying protective coating and heat treatment, forming a protective layer and sealing the through holes to avoid deformation caused by air expansion.

Benefits of technology

Through the design of through holes and the formation of protective coatings, the deformation of the pot rack during the heat treatment process is avoided, the yield of the protective layer and the overall production pass rate are improved, consumables are saved and the defective rework rate is reduced.

Abstract

The invention provides a manufacturing method of an energy-gathering pot rack and an energy-gathering pot rack, and relates to the technical field of kitchenware. The method comprises the following steps: providing an energy-gathering pot rack body; processing a through hole: opening a through hole connected to a cavity between two layers of the energy-gathering pot rack body on the energy-gathering pot rack body; coating a protective coating: coating a protective coating on the surface of the energy-gathering pot rack body provided with the through hole; heat treatment: heat-treating the energy-gathering pot rack body coated with the protective coating so that the protective coating forms a protective layer on the energy-gathering pot rack body to obtain the energy-gathering pot rack; during the heat treatment, air in the cavity of the energy-gathering pot rack body is connected to the outside through the through hole, during the heat treatment, deformation of the energy-gathering pot rack body is avoided, stability of the shape of the energy-gathering pot rack body in the process of forming the protective layer is ensured, and the production qualification rate of the energy-gathering pot rack is improved.
