Description

一种合金材料在厨具制备中的应用
技术领域 本发明涉及一种材料在生产厨房用具中的应用，更具体地说，涉及
SUS436L材料在生产厨用容器， 如器皿， 锅类制品、餐具等中的应用， 特别是， 在生产用于电磁炉和导热导磁要求高的厨具中的应用。 背景技术 厨房用具如烹饪器皿， 如锅类产品， 由早期的铁锅、铝锅、陶瓷逐 渐地发展到以 0Crl8Ni9材料为主流的不锈钢制品， 并迅速发展起来。 早期的铁制品厨具， 众所周知， 该材料容易生锈， 有磁性。 随后发展 了铝制品厨具， 其具有易加工， 无磁的特点， 但在加工过程中需要表 面化学处理， 喷油处理以达到一定的硬度及防止氧化， 同时在内里必 须喷上不粘涂料才能安全使用。 0Crl8Ni9 (钢型号为 304， 下文中简称 SUS304材料）是一种奥氏体钢，其化学成份为 (WT%): Cr 17-19; Ni 8-11; C^0.06; Si^l.00; Mn 2.00; S^O.030; P^0.035; 余量为 Fe。 其无磁 性， 耐腐蚀， 易加工， 而且其制品能防锈， 表面光亮美观， 可用于燃 气炉和电炉， 但用于电磁炉时， 需在底部加复合底。 电磁炉是近年来迅速发展起来的一种炉具，其是利用电磁效用实现 加热的方式。 只有由有磁性的材料所制造的制品才能用于电磁炉。 因 此， 一般来说， SUS304材料所制造的制品是不能用于电磁炉的。 由于 其各方面性能均优良， 如果要用这种材料制造电磁炉用烹调器皿， 则 必须在其底部复合上有磁性的材料。 例如， 目前常用的是采用钢铝钢 复合底， 即在由该种材料制造的器皿的底部先焊合一层铝或者铜， 接 着再焊合一层有磁性的不锈钢材料， 但该钢铝钢的材料的成本较高且 不易于加工。 复合底的示意见图 1。 图中 A部分可采用 304材料， B 部分采用纯铝或铜， C部分可采用具有磁性的金属材料， 如 1 7 (简 称 SUS430)钢（其化学成份为： Cr 16-18; C^0.12; Si^0.80; Mn^0.80; S^O.030; P^0.035; Ni 0.60;另加入了微量的 Mo和 Ti， 余量为 Fe)， 铜等材料。 由于 SUS304材料的不能直接用于电磁炉等缺点，人们一直在寻求 一种可以替代 SUS304材料的可用于加工电磁炉用制品并具有其它优 点的多功用厨具材料， 但一直没有成功。 且由于很多材料的加工性能 差， 如 SUS430材料， 势必造成制造成本的提高等问题，尤其是深拉伸 的容器和器皿， 因此人们始终没有发现一种合适的材料， 使得很多研 究者放弃了这种努力。
SUS436L材料是一种铁素体钢。 化学成分如下 (wt%): Cr 17-19; C 0.025; Si^ l.00; Mn^l.00; N^0.02; Ni^0.60; Ti^0.75; MoO.75-1.50; 余量为 Fe。 该材料中几乎不含镍， 同时加入了微量的钼和钛元素， 具 有优良的防腐性能， 同时还拥有高效的导热性及导磁性。 该材料主要 用于汽车***和排气管上。 发明概述 本发明的一个目的是研究和寻找一种材料， 该材料适合于生产厨 具， 尤其是适合于生产可用于电磁炉和导热导磁要求高的烹饪器皿。 所述烹饪器皿可用于燃气炉、 电炉和电磁炉。 本发明的另一个目的是研究和寻找一种材料，该材料适合于生产厨 具， 尤其是用该材料生产的电磁锅和导热导磁要求高的烹饪器皿可以 不需有复合底， 即一体化。 这样， 该厨具不但成本降低， 而且克服了 传统复合底所带来的种种缺点。 本发明的又一个目的是研究和寻找一种材料，该材料适合于生产厨 具， 并且适合于生产厨具的复合底。 从而该厨具可以根椐需要进行复 底加工以形成相同材料的再次复合底， 其加工后的性能优于钢铝钢复 合材料， 并克服常规复合底的复合材料在使用时容易氧化和导热性能 差的缺点。 本发明的进一步目的是研究和寻找一种材料，该材料适合于生产厨 具， 并且具有上述优点， 而且材料及加工成本较低。 本发明的另一个目的是研究和寻找一种材料，该材料适合于生产厨 具， 并具有上述优点， 而且可以用于生产其它各类厨用容器。 本发明的其它目的和优点， 通过阅读本申请文件， 将更为清楚。 本发明人经过研究、筛选和反复实验，发现铁素体钢，化学成分为
(wt%): Cr 16-19， 0.025, Si^ l.00, Mn^ l.00, N^0.02, Ni 0.60， Ti^0.75, Mo0.75-l.50, 余量为 Fe的材料可以用于厨具的 制造， 并可达到本发明的所有目地和要求。 具代表性且市场上可获得 的这种材料的型号有 SUS436L (中国国标)。本发明人经过反复实验并 解决了 SUS436L材料的加工问题， 从而首先成功地将 SUS436L材料 应用于厨具制造行业。 SUS436L材料用于制造厨具， 具有由 304材料 制造的厨具的所有优点， 例如， 耐蚀性， 同时因为该材料具有磁性， 因此其可制造一体化的用于电磁炉、 燃气炉、 电炉的制品。 另外， 用 该材料生产的厨具， 由于其可一体化， 因此降低了厨具制造的生产成 本。 另外， 由于该材料不含镍， 同时对环保， 节约能源起到了有益的 作用。 附图说明 图 1表示复合底示意图。
图 2表示本发明的一个实施例的示意图。
图 3表示本发明的另一个实施例的示意图。
图 4本发明应用材料的抗蚀性与其它材料的比较。 发明详述 在本发明的一个方面， 提供了一种由一种新型材料制成的厨具制 品。 在本发明中， 所述的厨具制品包括烹调器皿、 餐具或厨用容器。 可用于本发明的新型材料的化学成份如下 (Wt%) :
Cr 16-19; C^O.025; Si^ l.00; Mn^l.00; N 0.02; Ni^0.60; Ti 0.75; Mo 0.75-1.50; 余量为 Fe。 市场上已有的代表材料有 SUS436L。 用于本发明的 SUS436L材料的性能与其它材料性能比较的数据如 1所示：
表 1
Figure imgf000005_0001
从以上数据中可以看出， SUS436L钢具有良好的导热性和导磁性， 同时具有优良的抗蚀性。 用于本发明的 SUS436L材料的抗蚀性与其它材料的对比数据见图 4， 从图中可以得出与表 1相同的结论。 在本发明的厨具（圆筒形）生产过程中， 采用了以下生产工艺： 1 ) 冲压， 根据成品制品的规格， 在冲床上冲压出不同的直径尺寸的圆片; 2) 滚油， 由于 SUS436L材料的屈服强度、 延伸率较 304材料低， 经 滚油过程中使用的拉伸油要多一些，而且，由于 SUS436L材料比较软， 容易划伤， 因此， 在加工过程中需特别注意； 3 )拉伸阶段， 根据拉伸 深度可分一次拉伸和两次拉伸完成， 第一次拉伸系数可达 0.52〜0.55， 第二次拉伸系数是 0.78 0.8， 一般达到所要求的尺寸； 4)根据产品要 求可做各种形状； 5)表面处理。 在本发明的另一方面， 提供了一种烹饪器皿， 它由 SUS436L材料 一体化而制成。 其加工工艺为： 1 )冲压， 根据成品制品的规格， 在冲 床上冲压出不同的直径尺寸的圆片； 2)滚油， 由于 SUS436L材料的 屈服强度、 延伸率较 304材料低， 经滚油过程中使用的拉伸油要多一 些， 而且， 由于 SUS436L材料比较软， 容易划伤， 因此， 在加工过程 中需特别注意， 3)拉伸阶段， 根据拉伸深度可分一次拉伸和两次拉伸 完成， 第一次拉伸系数可达 0.52〜0.55， 第二次拉伸系数是 0.78〜0.8， 一般达到所要求的尺寸； 4) 根据产品要求可做各种形状； 5 )表面处 理。 在本发明的另一方面，还提供了另一种烹饪器皿，它是由 SUS436L 材料复底制成。 复底工艺为在器皿完工后， 用过粉筛在器皿底部涂上 钎剂及钎料， 再用钎焊机将铝片或铜片及复底片焊于器皿底部。 复底 片可使用同样的 SUS436L材料。 在复底过程中， 特别要注意钎焊温度 的控制， 温度过高则会使复合的底部形成过热， 造成虚焊， 同时在钎 焊必须加散热圈， 否则会使锅身变形。 同时亦可做压力焊锅类， 锅身 和包底片可全部使用 SUS436L材料。 根据本发明，可用于本发明的材料一般是板材，其厚度根据成品的 要求而变化， 例如， 板厚可以为 0.4-2.5毫米之间。 所生产器皿的高度 可以根据需要在 10-600毫米之间变化，优选为 50-320毫米；器皿的直 径可以在 100-600毫米之间变化， 优选为 100-360毫米。此夕卜， 根据本 发明， 所生产的主要产品包括锅类、 盆类， 特别是用于电磁炉和导热 导磁要求高的厨具。 根据本发明， 用 SUS436L材料生产的厨具系列可以完全取代现有 的铝制品和 304系列制品。 因铝制品缺点为： 第一， 不能用作电磁锅: 第二， 外面需作化学处理以达到一定的硬度及防止氧化， 它的寿命和 美观性因此会低于 436材料； 第三， 内里必须喷上不粘涂料才能安全 使用。 反之 436材料却能避免上述之一切缺点， 并能更有效地发挥它 的导磁性及导热性之优点。 与此同时可根据不同市场的需求考虑内里 喷不粘涂料或不喷不粘涂料。 实施例 实施例 1 (生产一体化锅， 如图 2)
