Problems solved by technology

This situation is not conducive to development. On the one hand, the price of raw materials has risen rapidly and greatly, and the supply has become increasingly tight, which has greatly increased production costs and seriously restricted the production and development of heat-resistant ceramics; on the other hand, lithium materials are increasingly Use heat-resistant ceramic utensils, which have high firing temperature, small firing temperature range, difficult process technology control, relatively small thermal conductivity, and low heat utilization rate in daily use; there are often bursts when used in conjunction with induction cookers. , the service life is not long, damage the service life of the induction cooker and other issues

Abstract

The invention belongs to the technical field of ceramic materials, and provides a novel iron-manganese heat resistant cooker and a production technology thereof. A low expansion coefficient raw material such as spodumene is not required in the formula of the product; the heat conductivity coefficient of the ceramic ware is greatly improved by improving the heat conductivity coefficient and the thermal shock resistance of ceramic; the sintering temperature is low, and the maturing temperature is wide in range and is 1,160 to 1,230 DEG C; the product is high in superior quality, can be quickly sintered, can tolerate the heat exchange of 500 to 20 DEG C without cracking, has the advantages of low energy consumption, high heat conductivity, high impact strength, thermal shock resistance and the like, and can be used for directly steaming, boiling, stewing and stir-frying food over a heat source; and the cooker keeps the cooking flavor of the conventional ceramic ware, does not decompose nutritional components in the food, and is an ideal multifunctional cooking ware for modern families, hotels and restaurants.

Description

technical field [0001] The invention belongs to the technical field of ceramic materials, and in particular relates to an iron-manganese heat-resistant cooker and a production process thereof. Background technique [0002] Ceramic cooking utensils have unique advantages such as good heat storage, environmental protection, and corrosion resistance. With the improvement of people's living standards, changes in lifestyles and eating habits, the market's demand for heat-resistant porcelain utensils is increasing, and the requirements are also increasing. Higher and higher. Looking at the daily-use heat-resistant ceramic utensils in the market, the domestic production of heat-resistant daily-use ceramics mostly uses spodumene produced in Australia as the main raw material, and a few companies use the appearance and texture of imitation purple sand, combined with lithium materials. This situation is not conducive to development. On the one hand, the price of raw materials has ris...
