Abstract

The invention relates to a method for producing stainless tool. Wherein, it comprises first drawing, second drawing, annealing, third drawing, treating surface. And the inventive product has long service life, uniform thickness of inner wall and bottom, simple process, low cost and environment friend.

Description

technical field [0001] The invention relates to a method for manufacturing metal utensils; more specifically, the invention relates to a method for manufacturing stainless steel utensils, which belongs to the field of mechanical processing. Background technique [0002] Stainless steel utensils such as frying furnaces are used for frying chicken legs, chicken wings, sausages, hamburgers and other foods. The fried foods are fragrant, crisp and crisp, and are deeply loved by people, especially children or teenagers. For the needs of frying food and preventing the oil from splashing out of the pot during frying, the inner cylinder of the fryer is generally deeper. The existing frying furnace inner cylinder is mainly formed by welding stainless steel plates. The oxide film of the welded frying furnace inner cylinder formed by welding is easily damaged and rust spots are generated under the condition of high temperature, which not only causes The service life of the cylinder is ...
