Description

耐热陶瓷锅
技术领域
本发明涉及陶瓷领域，更具体地，涉及一种耐热陶瓷锅。
背景技术
陶瓷锅是家居、餐馆中理想的烹调器，在对食物的煮、煲、煎、炒等方面具有独特优点，而且健康环保。但是作为日常对食物加热的锅具，首要的便是耐热性，陶瓷锅相对于金属锅具，耐热性能还是相对较差一些，针对煮、蒸等较温和的烹调方式，由于受到锅内水份的保护，锅底受热较为均匀，陶瓷锅可与金属锅具相媲美甚至更甚一筹，但是如果针对炒、炸、煎等高温急火的加热方式，陶瓷锅受到温差急剧变换的影响，则表面容易受到损伤甚至炸裂。
发明内容
本发明的目的是提供一种耐热陶瓷锅，热膨胀系数适当，抗热震性能好，经久耐用。
本发明目的通过以下技术方案予以实现：
提供一种耐热陶瓷锅坯料，其重量份数组成：龟纹石17～23份，翠榴石11～16份，锆石4～8份，黑泥5～9份，氧化铝2～5份，夕线石1～3份，十字石2～5份，竹炭粉3～7份，鹅管石5～8份，海绿石9～12份。
提供一种耐热陶瓷锅釉料，其重量份数组成：碳酸钡2～4份，烧滑石12～18份，碳酸钠4～7份，釉果18～25份，氧化锡1～3份，二氧化硅14～19份，二氧化锆3～6份，氮化硼2～5份，硅镁石7～16份，透辉石5～10份。
提供一种耐热陶瓷锅，制作方法包括以下步骤：
(1)制备坯体：按重量份数取坯料原材料，混合后入球磨机中湿法球磨，球磨时加入的水量，以水份重量占水分重量加总干料的重量％计为：25～35重量％，陈腐18～24h后过200～280目筛成坯泥备用；
(2)制备釉料：按重量份数取釉料原材料，混合均匀，湿磨5～8h，过300～325目筛筛余0.05％成釉浆备用；
(3)将坯泥注浆成型为锅坯，干燥后880～1080℃素烧8～12h，保温3～5h，然后冷却至室温，备用；
(4)在锅坯上施釉，干燥后入窑烧制，烧制条件为：以30℃/min的速率升温至900℃，保温1h，再以20℃/min的速率升温至1200℃，保温2h，再以10℃/min的速率升温至1400℃，保温3h，然后以15℃/min的速率降温至1000℃，保温5h，最后自然冷却，得到耐热陶瓷锅。
进一步地，所述步骤(4)中的施釉方法为浸釉法。
进一步地，所述步骤(4)中的施釉厚度为1.2～1.6mm。
与现有技术相比，本发明具有以下有益效果：
本发明提供了一种耐热陶瓷锅，锅体光泽度好，釉面晶莹，无针孔，热膨胀系数适当，抗热震性达到550～20℃热交换一次不裂，吸水率在5％以内，经久耐用，易于清洗，适用于煎、炸、炒等高温急火的烹饪方式。

（1）制备坯体：按重量份数取坯料原材料，混合后入球磨机中湿法球磨，球磨时加入的水量，以水份重量占水分重量加总干料的重量％计为：25～35重量％，陈腐18～24h后过200～280目筛成坯泥备用；
（2）制备釉料：按重量份数取釉料原材料，混合均匀，湿磨5～8h，过300～325目筛筛余0.05%成釉浆备用；
（3）将坯泥注浆成型为锅坯，干燥后880～1080℃素烧8～12h，保温3～5h，然后冷却至室温，备用；
（4）在锅坯上施釉，干燥后入窑烧制，烧制条件为：以30℃/min的速率升温至900℃，保温1h，再以20℃/min的速率升温至1200℃，保温2h，再以10℃/min的速率升温至1400℃，保温3h，然后以15℃/min的速率降温至1000℃，保温5h，最后自然冷却，得到耐热陶瓷锅。
4.根据权利要求1所述的耐热陶瓷锅，其特征在于，所述步骤（4）中的施釉方法为浸釉法。
5.根据权利要求3所述的耐热陶瓷锅，其特征在于，所述步骤（4）中的施釉厚度为1.2～1.6mm。
