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
The invention belongs to technical field of ceramic material, particularly the heat-resisting cooking pot of a kind of ferrimanganic and production technique thereof.
Background technology
The cooking utensil of ceramic material has that accumulation of heat is good, environmental protection, the particular advantages such as corrosion-resistant, and along with the raising of people's living standard and change and the food habits of mode of life, market is increasing to the demand of heat resisting porcelain vessel, requires also more and more higher.And make a general survey of the daily heat-stable ceramic vessel in market, and the heat-resisting domestic ceramics of domestic production, the triphane that multiplex Australia produces is main raw material, minority enterprise adopts the appearance tactile impression of imitated boccaro, is combined making with the lithium material.Such present situation also is unfavorable for development, and on the one hand, prices of raw and semifnished materials lift velocity is fast, amplitude is large, and is becoming tight supply day, has greatly improved production cost, has seriously restricted the prodution and development of heat-stable ceramic; On the other hand, the daily heat-stable ceramic vessel of lithium material, its firing temperature is high, and firing range is little, and Technology control difficulty is large, the thermal conductivity less, heat utilization efficiency is lower in the routine use; With being used of electromagnetic oven in often exist explosion, work-ing life is not long, the problems such as work-ing life of damage electromagnetic oven.
As everyone knows, ceramic industry is the traditional industries of high energy consumption, to this, constantly reduces energy consumption, and protection of the environment reduces cost, improves quality, enlarges the scope of application, is the ceramic industry eternal proposition that develops in a healthy way, be energy-saving and emission-reduction in the urgent need to.Therefore, the production domesticization of heat-resisting domestic ceramics raw material, universalness and energy-saving and cost-reducing, simplify production technology, become domestic daily heat-stable ceramic enterprise and be badly in need of the technical problem that solves.
Summary of the invention
The present invention will provide the heat-resisting cooking pot of a kind of ferrimanganic and production technique thereof.
Above-mentioned purpose of the present invention is to realize that by following technical scheme namely the solution of the present invention is: the heat-resisting cooking pot of a kind of ferrimanganic is characterized in that cooking and appoints body by composition of raw materials to be by weight percentage:
The fired pottery that forms.
The production technique of making the heat-resisting cooking pot of above-mentioned ferrimanganic is as follows:
By above-mentioned prescription batching, through coarse crushing, selection, in broken, ball milling, fineness test, sieve, press filt, vacuum pugging, pug are old, secondary vacuum pugging, roll forming base substrate, or press filt by pull an oar, sieve, the injection forming base substrate; Above-mentioned molding blank again drying, repaired biscuit, Shang Shui, oven dry, low temperature biscuiting, bique is repaired, is fired, and maximum sintering temperature is 1230 ℃, and firing range is 1160 ℃-1230 ℃, thereby fires finished product.
In the above-mentioned technique, the vessel of glazing then adopt oxidizing atmosphere to fire after the bique finishing, do not need the vessel of glazing then can adopt reducing atmosphere to fire.
After the present invention adopts technique scheme, compare with prior art processes and to have following advantage: 1, do not need to use the low-expansion coefficient raw materials such as triphane, prescription adopts domestic reserves abundant, also there is not the higher common mountain soil of a large amount of iron content, manganese that use, iron, manganese ore or ferrimanganic ore dead meal, the ceramic raw materials such as general unselected clay, feldspar, quartz.Raw material sources are extensive, and most areas can be gathered materials on the spot, and Costco Wholesale is cheap, and raw material does not need to calcine in advance, Ball-milling Time is short, and firing temperature is low, and firing range is wide, be applicable to that oxidation is burnt till and reductive firing, product with stable quality, appearance tactile impression are similar to the purple-clay product in Yixing.
2, adopt the technological method that improves ceramic coefficient and heat-shock resistance, content of iron and manganese is high, take ferrimanganic as main fusing assistant, other fusing assistants reduce firing temperature for auxiliary, increase substantially the thermal conductivity of pottery, strengthen the porcelain thermal shock resistance, in order to further improve the ability of the cold and hot exchange of pottery opposing, durable in use to reach porcelain, and can explosion when be used for to make cooperating the ceramic kitchen ware that electromagnetic oven uses, the safe handling that improves heat-stable ceramic.Through check, its resistance toheat: various foods can directly be steamed, boil, stew, fry to 500 ℃ of-20 ℃ of heat exchanges once without cracking phenomena, at thermal source.
3, production technique is similar to the production technique of conventional ceramic, pug performance and purple clay approach, be applicable to roll forming, drain casting moulding, the pressure of domestic ceramics, plastic pressure forming etc., production process is simple, firing temperature is low, 1160 ℃ of firing ranges--1230 ℃, reach the requirement of energy-saving and emission-reduction, environmental protection.Moreover, being suitable for Quick Oxidation atmosphere and reducing atmosphere and burning till, firing temperature does not affect the resistance toheat of these goods, can mate with low-expansion glaze, forms multiple serial decorated style.
