Google translate明万历三十一年(1603年)的“吕宋惨案”(当时西班牙殖民当局屠杀了25000余名在此居住的华人,其中大部分祖籍福建漳州和泉州)发生之后,死里逃生的马尼拉闽南人亲眼目睹了钢铁与技术的厉害,它们比大刀、长矛更占优势。他们明白只有学西人之长技,才能有效阻止这种惨绝人寰的悲剧再次发生。勤奋好学而又聪明上进的闽南人不仅学习西班牙人铸造火炮的工艺流程,还将中国先进的熔铁工艺与西人的铸铜技术相融合,巧妙地利用铜的熔点(1083℃)远低于铁(1538℃)的物理性质,在“铁胎”(炮管)浇注冷却以后,再用泥模或用失蜡法制模,并浇铸铜壁,透过“铁胎”外铜壁凝固时的收缩力,加强炮体抗压强度,铸造出数千斤重铜铁炮管的新式红夷大炮。这种新式红夷大炮告别了中国传统火炮的“受药不多,放弹不远,不迅不直”和“微弱的炮口初速”时代,成为“羌敌天下之神物”。不仅如此,这些闽南人还偷偷学得西班牙人使用火炮的技术,包括大炮的测距、瞄准、调整仰角、装填火药乃至最后的发射要领,并代代相传。
战争是武器的威力与作用的历史见证。“萨尔浒之战”惨败的7年之后,宁远大战在即。由闽南人铸造的11门红夷大炮被安放在城外演武场上。围绕这11门红夷大炮是否参加与努尔哈赤的生死决战,人们争论不休。有人担心会重蹈辽东战役之履辙,大炮炸膛而杀害自己的士兵,有人认为这会被敌人所用,主张用锻铁将各炮的火门封死,莫衷一是。
火器把总彭簪古与孙元化在京城受过严格训练,对这批红夷大炮的巨大威力与作用心中有数。他们认为可以“凭坚城,用大炮”,以罗立为首的26位闽南炮兵支持彭簪古的战术主张。守将袁崇焕认为这11门红夷大炮身管长,管壁厚,射程远,是击杀快速密集骑兵的先进武器,他认为“虏利野战,惟有凭坚城以用大炮一着”。
Hokkiens are diligent, eager to learn and savvy people indeed from past until now. History is always repeating itself.diligent, eager and savvy MINNAN people not only learn the process of the Spanish casting artillery, but also combine China's advanced molten iron technology with the Western copper casting technology, skillfully utilizing the melting point of copper (1083 ° C) is much lower than The physical properties of iron (1538 ° C), after the "iron tire" (barrel) casting cooling, then use the m&d mold or the lost wax method to mold, and cast the copper wall, through the "iron tire" outer copper wall solidification The contraction force, strengthening the compressive strength of the gun body, casting a new type of red cannon with thousands of pounds of copper and iron barrel.
