Magnesian heat-resistant casserole

Abstract

The invention discloses a magnesian heat-resistant casserole. The magnesian heat-resistant casserole comprises a casserole blank body and porcelain glaze arranged on the surface of the casserole blankbody, wherein porcelain clay for producing the casserole blank body comprises the raw material ingredients in percentage by mass: 40% to 50% of talcum, 20% to 30% of kaolin, 4% to 8% of clay, 8% to 15% of aluminum powder and 15% to 25% of kaolin washing sludge; and the porcelain glaze comprises the raw material ingredients in percentage by mass: 30% to 40% of talcum, 15% to 25% of quartz, 3% to 6% of aluminum powder, 25% to 35% of kaolin washing sludge, 2% to 6% of calcite, 4% to 12% of potassium feldspar and 5% to 10% of spodumene. Specific processing steps for producing the magnesian heat-resistant casserole are as follows: 1) carrying out weighing and material taking; 2) preparing blank mud; 3) preparing the porcelain glaze; 4) carrying out blank producing and trimming; 5) carrying outbiscuit firing glazing; and 6) carrying out high-temperature firing. The magnesian heat-resistant casserole has the characteristics of withstanding quenching and quick heating, being non-toxic and harmless, being good in thermal effect, difficult in rusting and easy to wash, and the like; and the porcelain clay cost of the magnesian heat-resistant casserole is only about one fifth that of a general casserole, and the production cost is reduced greatly while the quality of the product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a magnesium heat-resistant casserole. Background technique [0002] Casserole (English name: Casseroles) is a kind of cooking utensils; traditional casserole is a ceramic product made of quartz, feldspar, clay and other raw materials that are not easy to transfer heat. Uniform, slow heat dissipation and other characteristics; however, due to the production process and raw material problems, the traditional casserole is not resistant to temperature changes, easy to burst, and cannot be dry-fired; in response to this problem of the traditional casserole, after nearly ten years of research and development and improvement, in the raw materials Spodumene is added to create a high-temperature-resistant casserole, which enables the casserole to withstand hundreds of degrees of high temperature dry burning without cracking while maintaining its original advantages, which greatly...

Problems solved by technology

[0003] However, in recent years, with the country's new energy needs, spodumene is used to refine lithium carbonate, and then lithium carbonate is used to produce lithium batteries, resulting in a shortage of spodumene, and the price of spodumene has also increased from several thousand yuan per ton. The price rose to tens of thousands of yuan, and the price soared all the way. In the formula of traditional cushion-resistant casserole clay, the amount of spodumene is generally 30-48%, which is relatively large, causing the overall cost of china clay to soar; the production of traditional heat-resistant casserole clay The total cost is about 5,000 yuan per ton, which restricts the production of heat-resistant casserole
