上午9时，记者来到山东港口日照港（600017）岚山港区木材泊位前沿，现场作业一片繁忙。伴随着门机运转的沉稳节奏，巨大的吊臂在空中划出有力弧 线，将一根根进口原木从甲板精准抓取，稳稳装载至转运车上。 对于动辄数万方的木材船来说，2小时，不仅关系到单船的作业效率，更影响整个泊位的周转和客户的物流成本。同时，频繁的机械吊装对设备损耗较 大，也构成了潜在的安全压力。"效率就是生命，与时间的赛跑必须赢。"三公司木材专班决定打破常规，探索新的作业模式。 转机来自现场作业时的细致观察。张帅注意到，夹木机在甲板上移动时的灵活与在吊装时的笨重形成鲜明对比。 "夹木机既然能自己'走'，为什么非要吊着进出？"看似简单的疑问，像一颗火花，点燃了大家的灵感。然而，夹木机高3.2米，半开舱盖间距仅1.8米，近1 米的"身高差"成为摆在眼前的难题。 在繁忙作业的甲板上，一台黄色夹木机格外引人注目，它正从仅开启一半的船舱盖下，沿着木材搭建的斜坡"自驾"入舱。 这个被称为"开半扇门"的操作，是日照港三公司木材业务降本增效的关键一招。该工艺通过优化设备进出舱流程，将单舱机械吊装耗时缩短50%以上，实 现作业效率与安全水平的双提升。 "舱盖不开 ...

Core Viewpoint - The Chinese steel industry is experiencing stable production and operational performance in the first quarter of the year, with significant year-on-year growth in steel output, laying a solid foundation for positive development throughout the year [1]. Group 1: Production and Performance - In the first quarter, China's steel production exceeded 350 million tons, marking a year-on-year increase of 6.1% [1]. - The crude steel production reached 259 million tons, with a growth of 0.6%, while pig iron production was 216 million tons, up by 0.8% [1]. - The China Iron and Steel Association indicated that the industry's operational performance has improved compared to the previous year [1]. Group 2: Industry Transformation and Environmental Initiatives - The steel industry is currently in a critical period of transformation and upgrading, focusing on green and low-carbon development [1]. - As of April 20, 2025, 141 steel enterprises have completed ultra-low emission transformations, covering crude steel capacity of approximately 591 million tons [3]. - The industry is shifting from a linear "resource-product" model to a closed-loop model of "resource-product-recycled resource" [3]. Group 3: Future Goals and Achievements - By the end of this year, key regional steel enterprises are expected to complete their ultra-low emission transformations, establishing the world's largest clean steel production system [4]. - Over the past year, China has eliminated 300 million tons of outdated steel production capacity, with over 45% of crude steel capacity undergoing ultra-low emission transformations, significantly reducing major pollutants by over 75% [4]. - The goal is for over 80% of steel production capacity to complete the transformation by the end of 2025 [4].
