安如泰山 信守承诺 【国投期货|化工视点】 烧碱专题： 下游氧化铝需求分析 专题报告 在烧碱的下游需求中，氧化铝需求占比最大，达到30%，对烧碱有较强的议价能力，而今年烧碱行情的大 涨大跌，背后与氧化铝有着密切的关联，下文我们将从氧化铝角度分析烧碱的需求，以及背后驱动今年行情剧 烈波动的原因。 1、进口铝土矿耗碱量低 氧化铝是烧碱最大的下游，占比为30%，烧碱需求量跟氧化铝行业产量增速密切相关，烧碱的需求受到氧 化铝产量增速影响以外，还受到铝土矿品质的影响。氧化铝生产工艺有三种，为拜耳法、烧结法、拜耳烧结联 合法，由于拜耳法生产工艺简单，流程短，产品质量高，目前主流的生产方法是拜耳法，约占全国氧化铝产能 的90%以上，全球占比达到95%以上。拜耳法使用烧碱，适于处理高品位的铝土矿； 烧结法使用轻碱；联合法 产能很少，仅山西、重庆地区部分氧化铝装置维持两种方法共存的生产工艺，一般两者价差波动不大时，不太 会轻易更换设备，只有价差严重失衡时，才会选择更换设备。 想要 ge 代招 铝+矿 the may 智液 aku 曲级铝 | 矿石类型 | 铝硅比(Al/Si) | 单吨氧化铝耗碱量(kg) | 矿耗(吨矿/吨氧 ...

苯乙烯周报 E B ：供需边际转弱库存止降 ， 关注原料共振机会 广发期货研究所 化工组 金果实 从业资格：F3083706 投资咨询资格：Z0019144 本报告及路演当中所有观点仅供参考，请务必阅读此报告倒数第二页的免责声明 观点及策略建议 苯乙烯主要观点：原油端，虽然OPEC+增产预期强，但是宏观维稳，加之旺季提振，油价维持震荡运行。纯苯端，国内供需双增但供增大于需增，进口方面由于亚美套利窗口 未打开而日韩检修装置陆续回归，预计高进口将持续。纯苯港口库存去库不畅，同比压力较大，驱动上对苯乙烯形成拖累。苯乙烯方面，周度供增需减，其中上游6月有装置复产， 而需求端部分下游进入淡季，3S端从利润及库存看存在压力，预计对苯乙烯价格难形成有效驱动。苯乙烯库存周内止降累库，后续预计进入震荡阶段主要关注同比的绝对水平。当 前苯乙烯利润估算下估值仍偏高，结合纯苯基本面看估值回归大概率需要苯乙烯向下修复。故维持苯乙烯高空思路对待，节奏上需关注原料共振机会，警惕宏观风险。 期货策略建议：苯乙烯维持高空思路对待，近月上方一线阻力看7400 期权策略建议：卖出EB2507-C-7500 01 纯苯 壹 2025年苯乙烯、纯苯链 ...

本报告及路演当中所有观点仅供参考，请务必阅读此报告倒数第二页的免责声明 观点及策略建议 烧碱主要观点：短期看烧碱检修集中阶段供应压力有限，而需求端氧化铝有所好转，部分新投产支撑需求，山东主流厂采买价周内已两次提涨，当前在760元/湿吨。基本面供 需支撑叠加中美关税缓和带来的宏观积极驱动，支撑现货价格偏强运行。但需关注伴随价格反弹后非铝端的价格承接意愿以及煤炭、电力成本下调后烧碱估值问题。短期建议观 望，近月暂看2550附近阻力位，关注现货表现及检修高峰期碱厂库容情况。 氯碱周报 S H ：现货偏强 ， 周度碱厂累 库 V ：关税释放利好 ， 短期供需未见进一步矛盾下盘面反弹 广发期货研究所 化工组 金果实 从业资格：F3083706 投资咨询资格：Z0019144 PVC主要观点：受中美关税谈判进展刺激国内商品氛围积极，黑色系止跌反弹明显。短期看PVC基本面供需矛盾有限，其一在于检修较集中且自身库存同比压力有限，其二在于 印度BIS延期以及中美关税缓和带来的PVC制品抢出口预期。但中长线PVC在地产难见有效提振下仍表现出明显的过剩压力，而印度BIS及反倾销税始终作为潜在利空存在。故短期 PVC阶段性反弹为主， ...

Group 1: Report Industry Investment Rating - No relevant content provided Group 2: Core Views of the Report - Last week, the cost - inversion situation of alumina enterprises was still severe, production willingness decreased, and some enterprises cut production. There are still maintenance and production - cut plans in the future. The new northern production capacity has not shown an increase in supply, and there are negative news, leading to market观望 about its future production increase [3][8]. - The demand from electrolytic aluminum enterprises was mainly about capacity transfer last week, with theoretical demand remaining basically unchanged. The exchange warehouse receipt inventory decreased by 57,427 tons to 243,000 tons, and the factory warehouse decreased by 900 tons to 7,200 tons [3][8]. - Overall, some alumina enterprises are still in a theoretical loss state. With maintenance and production - cut plans and the new production capacity causing concerns, the alumina has good bottom support. However, it is also affected by the new production capacity commissioning process and the potential decline in costs, so it has the impetus to rebound but the height is expected to be limited [3][8].
