12月18日，太原北方重工集团生产车间内机器轰鸣，电光闪烁。国内首台φ820mm特大型无缝钢管矫直 机已完成安装，正式交付用户并进入试车阶段。这台设备是为中信泰富特钢量身打造，从设计到制造全 由企业自主完成，标志着我国在重型装备制造领域迈出新步伐。 车间里，激光下料、机器人焊接、数控加工等工序正忙碌进行。同时，湖北客户定制的无缝钢管生产线 和印度客户定制的不锈钢管穿孔机组也在加紧生产，预计春节前交付。 "创新是企业发展的核心。"企业负责人孙明堂介绍，企业每年将产值5%以上的资金投入研发，联合高 校攻克关键技术。通过产学研协同，矫直规格范围从传统3倍扩大到4倍，精度控制在微米级，解决了世 界级技术难题。 为匹配高精度制造，企业投入8000余万元更新设备，引入大型镗铣床、焊接机器人等，并上线ERP系统 实现智能化管控。这不仅提升了产品质量，更赢得了市场信赖。 截至目前，企业已接到来自印度、俄罗斯及国内多家集团的订单，总金额3200余万元。孙明堂表示，太 原北方重工将锚定国际一流目标，以技术驱动升级，为装备制造业注入新活力。（毕晶晶） ...

行业发展阶段：在两片罐出现之前，饮料罐主要是三片罐。1959年，美国大陆制罐公司和库尔斯公司共同研发出将一块金属圆片（坯料）通过巨大的压力在 模具中进行一次或多次"冲压"和"拉伸"，直接形成一个杯状的罐身和罐底一体结构，再装上罐盖。这是一次革命性的突破，它消除了罐身接缝，避免了焊缝 可能带来的泄漏问题，结构更坚固。这是"两片罐"的真正开端。但注意，早期的冲拔罐深度有限，罐壁较厚，且材料主要是钢板。1960年代-1970年代，这 个阶段铝材引入、拉拔与再拉拔工艺的突破；一方面使铝迅速成为饮料罐的理想材料（比钢更轻、不会生锈、延展性更好、表面更适合印刷），另一方面工 艺突破（D&I工艺），其通过"冲压"形成杯状初胚后，再进行多次"拉伸"和"熨压"，使罐身变长、变薄，形成我们熟悉的细长罐型。这个工艺让罐壁厚度分 布更均匀，可以制造出更轻、容量更大、外观更优美的罐体。因此，成为了现代两片罐生产的标准工艺。1970年代-1980年代，此时，随着技术进步和能源 成本上升，降低单罐材料用量成为核心目标。通过改进铝合金配方、优化热处理工艺和精确控制D&I工艺参数，罐壁厚度从约0.22mm下降到0.10mm以下。 1980年代 ...
