Description

说 明 书 一种铝钢复合锅及其铝钢复合工艺
技术领域
本发明涉及炊具技术领域， 尤其是涉及一种铝钢复合锅及其应用于锅 体底部的铝钢复合工艺。
背景技术
众所周知， 金属锅作为加热食品的主要炊具， 主要分为钢质（铁质）及 铝质两大类， 铝质锅的热传导性能远远好于钢质锅， 但是铝制锅不能适用 于现在普遍使用的电磁炉， 因此通常将铝质锅的底部设计成铝钢复合锅底。 例如公开号 CN201227154Y公开的是一种铝锅复合锅底,铝锅的锅底上复合 固定有导磁材料,所述铝锅的锅底上设有凸筋，凸筋将锅底分成若干区域, 导磁材料通过高温金属喷涂固定于各区域中， 由于锅底上复合固定有导磁 材料,可实现在电磁灶使用。 这种结构的最大缺点是导磁材料为凸筋， 不是 整片的结构， 因此存在受磁面积小且分散， 加热能力差的问题。
公开号为 CN101028668A的专利文件公开了一种制造复合底钢铝锅的方 法。 先由钢 -铝复合板制成钢-铝锅，内壁一面为钢片； 以铝-导磁金属板叠 合再与锅底的铝片叠合，点焊,连接成一体，高温加热后置于大吨位的摩擦 压力机上进行高温高压的压焊,获得钢-铝 -铝-导磁金属四层复合的复合底 钢-铝锅,其底厚大于锅壁厚。 它的特点是将各种金属的复合体焊接后同温 度加热， 再进行高温压焊， 这个专利解决了受热面积小的问题， 但由于铝 与钢的热涨系数不同， 压实冷却后可能导致各层金属不能有效地熔合， 影 响了复合锅体的牢固度。
还有中国专利 CN101352305A发明涉及一种复合底铝合金压铸锅。 它包 括铝合金压铸锅锅体、 不锈铁复底片,其特点是不锈铁复底片直接与锅体底 部平贴复合为一体。 该专利还涉及上述复合底铝合金压铸锅的复合工艺， 该复合工艺是经过压铸、 表面清洁、 涂敷复合剂、 贴片、 预压、 复合、 保 压冷却、 表面后续处理等步骤制得复合底铝合金压铸锅。 这种工艺比较合 理， 它是在复合的过程中通过感应线圈， 把铝加热到 450-630 °C， 持续时间 为 40-45s， 使得铝与不锈铁复底片结合， 这样的工艺流程时间太长， 不利 于大批量生产； 由于每一件锅体都是单独加热， 因此能源消耗高， 不利于 环境保护， 而且设备复杂； 大家都知道铝的熔融温度为 660°C， 因此热到 450-630°C铝离子的活性不足， 影响铝离子的扩散速度， 产品的牢固度不够 另外， 由导磁材料制作而成的板状金属锅底片存在诸多缺点， 一方面在 制作锅底片的过程中， 通常需要将金属板冲裁成圆形并冲出许多通孔， 因 此损耗了大量的原料， 造成了原料的浪费， 增加了材料成本， 另一方面， 类似平板结构的锅底片很难挤压入铝制锅体内， 因此加工难度很大， 制作 工艺复杂， 两者结合也不牢固。
发明内容
本发明的目的是为解决现有技术的铝钢复合锅底其铝钢结合牢固度不 高的问题而提供一种复合效率高， 钢铝充分熔合而结合牢固， 且适合大批 量生产的铝钢复合锅及其铝钢复合工艺。
本发明的另一目的是为解决现有技术的铝钢复合锅其锅底片底材料 消耗多， 制作工艺复杂、 加工难度大的问题而提供一种材料消耗少、 加工 方便、 成本低的铝钢复合锅。
本发明为达到上述技术目的所采用的具体技术方案为： 一种铝钢复合 锅的铝钢复合工艺， 所述的铝钢复合锅包括铝质锅体及嵌设于铝质锅体底 部的钢质锅底片， 其特征在于： 铝质锅体和钢质锅底片复合时， 把铝质锅 体加热到 400至 500°C， 钢质锅底片加热到 780至 820°C， 将两者在摩擦压 力机或油压机上轧制结合， 使钢质锅底片嵌入铝质锅体底部， 轧制结束后 自然冷却。 780至 820°C的钢质锅底片与 400至 500 °C的铝质锅体的表面在 压力机下接触， 由于二者有 300至 400°C度的温差， 而铝的导热性能很好， 这样在接触面铝离子的温度马上升到 660°C度的熔点温度以上与 800 °C的活 性钢离子迅速结合， 形成了接触面的钢铝渗透合金膜； 由于钢质锅底片厚 度较薄， 热容量有限， 加上铝的散热性能好， 铝表面超过 660 °C的高温， 只 是在局部形成， 且作用的时间很短， 因此不会对铝质锅体产生影响； 轧制 结束后自然冷却， 由于钢的温度高， 可以降低锅体铝件的冷却速度， 减少 收缩变形； 经过这种加工工艺成型的钢铝复合锅底， 其牢固度更高， 由于 加工速度快， 更适合大批量生产。
作为优选， 经过拉伸的铝质锅体， 所述加热温度为 450至 500°C ; 经 过压铸的铝质锅体，所述加热温度为 400至 450 °C。因为铝质锅体经过拉伸， 其刚度有所提高， 所以加热温度选择上限比较好； 而经过压铸的铝质锅体 刚度相对较低， 所以加热温度选择下限为佳。
作为优选， 所述的铝质锅体的锅底下表面采用喷丸或磨砂或加工成环 形波纹或加工成螺旋纹； 所述的钢质锅底片的上表面采用喷丸或磨砂处理。 将铝质锅体的下表面及钢质锅底片的上表面处理成粗糙的表面结构， 更有 利于铝钢离子的渗透结合， 提高结合的牢固度。
一种应用上述铝钢复合工艺制造的铝钢复合锅， 包括铝质锅体及嵌设 于铝质锅体底部的钢质锅底片， 所述铝质的锅体和钢质锅底片的接触面有 钢铝渗透熔合层。 这种铝钢复合锅在两种材料之间具有渗透熔合层， 不但 结合非常牢固， 而且两者之间的热传导性能好， 提高了铝钢复合锅的加热 性能。
作为优选， 所述的钢质锅底片由不锈铁丝制作而成， 所述的锅底片呈 螺旋状。 采用不锈铁丝制作螺旋状的锅底片没有材料损耗， 大大节约了锅 底片的制作材料， 而且材料易得， 制作简单， 降低了制作成本。 另外， 将 呈螺旋状的不锈铁丝压入锅体时所遇到的阻力较小， 降低了挤压加工的难 度。 这里所述的不锈铁是指不锈钢中导磁性能较好的例如马氏体不锈铁等， 此外， 也可以采用其他的导磁金属材料。
另外， 铝钢复合锅的钢质锅底片也可以由不锈铁丝交叉排布而成， 所 述的锅底片呈网格状。
作为优选， 所述的不锈铁丝的横截面呈圆形或矩形。 圆形的不锈铁丝 材料易得， 且压入锅体容易； 矩形的不锈铁丝制作成螺旋状时电磁炉有较 大的接触面积， 有利于提高电磁加热性能。
作为优选， 所述的矩形不锈铁丝的两侧边上设有凹槽。 这里所述的两 侧边是指与锅体底面垂直的边， 设置凹槽的目的是增加矩形不锈铁丝与锅 体结合的牢固度。
对于横截面呈矩形的不锈铁丝， 作为优选， 所述的矩形不锈铁丝倾斜 设置， 矩形不锈铁丝的下侧边与锅体底面之间存在夹角。 这一夹角通常为
30至 80度， 这样可以使锅底片在挤压时更容易压入铝质锅体内， 同时锅底 片压入后不锈铁丝的下侧边与锅体底面因为存在夹角关系而形成的空隙可 以被铝质锅体填充， 使锅底片不会脱落， 增加锅底片镶嵌后的牢固性。
作为优选， 构成锅底片的不锈铁丝在锅底片的底面位置具有平面结构。 当采用横截面为圆形的不锈铁丝或倾斜设置的横截面为矩形的不锈铁丝制 作锅底片时， 在不锈铁丝的锅底片底面位置设置一平面结构有利于提高锅 底片与电磁炉的接触面积， 从而提高电磁加热性能。
采用本发明的铝钢复合工艺时， 锅底片也可以下面的结构， 即钢质锅 底片由不锈铁制作而成， 所述的锅底片的外周设有包边结构， 锅底片的上 表面设有波浪状突起， 波浪状突起的顶部呈球形。 这里的波浪状突起位于 包边结构内侧的锅底片上表面， 锅底片的底面是大致的平面结构， 这一结 构与传统的平板状锅底片有着本质的区别， 传统的平板状锅底片为了确保 锅底片与铝质锅体的结合牢固， 锅底片上通常设置有大量的通孔， 在这些 通孔由于裸露在外， 通孔与铝质锅体的结合处容易受到外界的侵蚀， 从而 影响铝钢复合锅的使用寿命， 而本发明由于锅底片与铝质锅体的复合采用 特殊的工艺， 只需在锅底片的上表面加工出顶部呈球形波浪状突起， 即可 确保锅底片与铝质锅体的结合牢固， 这样铝质锅体在底部有一完整的钢质 锅底片， 可以提高锅底的耐腐蚀性能， 提高铝钢复合锅的使用寿命。 带有 包边结构的锅底片还可以充分环绕包住在压制过程中容易变形的铝质锅 底， 可以保证轧制后锅体的形状完整， 提高锅底的强度及锅底外表的刚度。
本发明的铝钢复合工艺及铝钢复合锅结构适用于铝质锅体的平底炒锅 及蒸煮锅等锅体采用铝质材料的炊具。
本发明的有益效果是： 它有效地解决了现有技术的铝钢复合锅底其铝 钢结合牢固度不高的问题， 还解决了现有技术的铝钢复合锅其锅底片底材 料消耗多， 制作工艺复杂、 加工难度大的问题， 本发明的铝钢复合工艺复 合效率高， 钢铝充分熔合而结合牢固， 适合大批量生产； 铝钢复合锅材料 消耗少、 加工方便、 成本低， 提高了企业的经济效益。
