Abstract

The invention relates to the technical field of kitchen cookers, particularly a manufacturing method of a cooking utensil. The manufacturing method comprises the following steps: S1. spraying ceramic glaze on a cooking utensil matrix; S2. preheating the cooking utensil with the sprayed ceramic glaze; S3. sintering the preheated cooking utensil; and S4. cooling the sintered cooking utensil. The process S2 comprises the following steps: S21. first preheating period: slowly heating the cooking utensil with the sprayed ceramic glaze from room temperature to 180-220 DEG C within 0.5-1 hour; and S22. second preheating period: slowly heating the cooking utensil with the sprayed ceramic glaze from 180-220 DEG C to 280-320 DEG C within 0.5-1 hour, wherein the heating speed of the second preheating period is lower than the heating speed of the first preheating period. The manufacturing method adopts the multiple preheating periods, so that the sintered cooking utensil has the advantages of favorable smoothness, favorable wear resistance, favorable glossiness, simple technique mode and wide application range.

Description

technical field [0001] The invention relates to the technical field of kitchen cooking utensils, in particular to a method for manufacturing cooking utensils, in particular to a method for manufacturing cooking utensils with better flatness and wear resistance. Background technique [0002] The research on ceramic glazes mainly focuses on the composition of glazes and the sintering process of glazes. The sintering process of glazes is generally divided into solid-phase sintering and liquid-phase sintering. Because solid-phase sintering requires lower temperature and less energy consumption, it is widely used in production. The traditional glaze solid-phase sintering process has a short preheating time and is preheated by rapidly raising the temperature to a certain temperature. The way of preheating by rapidly raising the temperature to a certain temperature, the moisture and organic matter in the glaze will volatilize too quickly in a short period of time, will block the g...
