A | 央视新闻客户端消息(新闻联播)：我国钢铁产量连续多年位居世界首位。 Vladimir Putin has prepared a cunning new “raw materials trap” relying on Bolivia’s fledgling lithium mining industry, with the trap expected to “snap shut” and leave the West again dependent on Russia for its raw material needs, Welt contributor Tobias Kaufer fears.,Pointing to the Latin American nation’s massive, untapped deposits of lithium, Kaufer expressed concerns over Russia’s interest in helping Sucre tap these resources, which are crucial for the production of batteries for electric vehicles.,According to the US Geological Survey, Bolivia’s proven lithium reserves are the largest in the world, with the country’s 21 million tons ahead of Argentina and Chile (which have 19 and 9.8 million tons-worth of reserves, respectively, and together account for more than 30 percent of global lithium output).,“Those with access to the deposits can have a say in the commodity’s prices and availability. Russia apparently has particularly good chances in Bolivia at the moment,” Kaufer wrote. For Europe, he warned, Moscow’s success in the lithium ‘poker game’ would make the commodity another area where the EU depends on Russia, just like with oil and gas.,Russia’s success will be contingent on “the outcome of the Bolivian political crime thriller,” the contributor stressed, pointing to the raging struggle between President Luis Arce, a member of former president Evo Morales’ Movement for Socialism party, and right-wing forces backed by the US attempting to overthrow leftist forces.,Ex-Bolivian President Jeanine Anez Sentenced to 10 Years in Prison Over 2019 Coup11 June, 01:54 GMT,“This is where Russia comes in. Morales is considered a clear supporter of Vladimir Putin,” Kaufer wrote, recalling the former president’s calls for an “international mobilization to stop the interventionist expansionism of NATO and the United States” in March following the escalation of the crisis in Ukraine, and years of efforts by Sucre to shore up ties with Moscow during his presidency.,“If Moscow now succeeds in supporting the socialist’s return to power, the path to the lithium deposits would be clear. At the very least, Morales could urge President Arce to sign a deal with the Russians,” the Welt contributor believes.,Rosatom, the Russian state nuclear giant, has expressed interest in helping Bolivia tap its lithium riches, and is one of six companies which have applied for their development. Others include Lilac Solutions (a US-based start-up with investments from BMW and Bill Gates’ Breakthrough Energy Ventures), Chinese battery giant CATL, and three other Chinese companies.,Along with its interest in Bolivia’s lithium, Rosatom has teamed up with Norilsk Nickel to mine for lithium ores in Russia’s Murmansk region. Last year, the company also announced plans to build a major lithium ion cell manufacturing facility in Kaliningrad, with the ambitious project hoping to begin churning out up to 4 GWh worth of batteries, or about 0.5 percent of total global demand, by 2024.,Morales' Legacy: Bolivian Joint Nuclear Project With Russia's Rosatom Unique for Latin America10 June 2021, 16:53 GMT。今年以来，钢铁企业依托全国重点实验室，聚焦高端特种钢材持续发力，不断实现核心技术突破，一大批高端钢材实现了自主量产。
B | 钢材如何做到强度过硬，还能抵御海水腐蚀？在河北唐山的钢铁实验室，记者找到了答案。钢材加工过程中会产生易导致材料脆化的碳化物，科研人员通过调控钢材原子结构，将碳化物有效包裹。 研究人员给记者算了一笔账，一台海上风电机要用钢数百吨，换上这种高性能钢，钢板可以做得更薄，合金用量也大幅减少。 如今，不只在海上，我国已经搭建起覆盖深海装备、舰船制造、航空航天等多场景的高端钢材自主研发量产体系，从材料配方、轧制工艺到批量生产实现全链条自主可控。 眼前这款是我国自主研发的“蝉翼钢”，厚度仅有0.07毫米，具备高强度、高延展性，达到全球精制钢顶级水平。 目前，这款钢材已广泛应用在集成电路基板、5G基站信号接收器等多个领域。而在航空航天领域，新研发的低膨胀特种钢材已经投入大飞机复合材料成型模具生产，数据显示，今年以来，已有7种高端钢材实现全新突破，面向新能源汽车、人形机器人、储能装备等新兴赛道，多款专用电工钢、高强结构钢实现批量下线，为新兴装备核心部件提供材料保障。 目前，我国已有3家钢铁企业入选全球“灯塔工厂”，累计培育36家卓越级钢铁智能工厂、2家领航级智能工厂。
