煅烧无烟煤市场 – 2024 年至 2029 年预测Calcined Anthracite Market - Forecasts from 2024 to 2029 |
预计在预测期内(2024-2029 年),煅烧无烟煤市场将以 3.5% 的复合年增长率成长。
推动煅烧无烟煤市场的主要因素是由于钢铁需求增加而导致的需求,因为钢铁用于钢包和高炉的脱碳。钢是一种高抗拉强度、低成本材料,是世界上最常用的製造材料。用于建筑物、混凝土钢筋、桥樑、基础设施、工具、船舶、火车、汽车、自行车、机械、机械电器产品、电器、家具和各种其他设备。
无烟煤适合作为灰铸铁、铸钢、钢厂等铸铁厂的增碳剂。当用作增碳剂时,无烟煤在约1400℃下煅烧并进行热清洗。
电动式无烟煤(ECA)是透过在电炉中在 1800°C 至 2200°C 下燃烧无烟煤而製成的。它具有高碳含量和高导热性和导电性。水分、挥发分、硫含量低,适合生产碳电极糊。
煅烧无烟煤的碳含量很高。脱羧可降低挥发物含量并提高煤的稳定性和纯度。煅烧无烟煤用于需要增加碳含量的各种工业製程。无烟煤依其等级具有不同的特性。标准级无烟煤含水分15%,挥发分10%,固定碳73%以上。同样,超高高等级无烟煤的水分为 9%,灰分高达 10%(干基),固定碳含量最低为 82%。
煅烧无烟煤主要用于炼铁,以提高炼铁和球墨铸铁的含碳量。高碳低硫,效果稳定。
煅烧无烟煤用于电炉(EAF),这是一种炼钢方法。根据世界钢铁协会的数据,基于电弧炉的钢铁产量约占全球产量的 26%。无烟煤通常用作碳源。
随着世界经济的发展,对钢材的需求也不断增加。钢材是建造道路、建筑物、港口、车站等的基本构件。印度是世界领先的高速公路建设国家之一。 2014 财年至 2023 财年,印度公路建设的复合年增长率为 5.3%。印度在 2022 财政年度建造了 10,457 公里的高速公路。 2023年为10,331公里。所有这些道路建设都需要钢材作为主要投入,导致钢铁製造对煅烧无烟煤的需求相对增加。
此外,根据联准会的数据,美国2023 年 1 月的建筑支出总额在 1,882,199 美元至 2,087,508 美元(百万美元)之间。这显示该部门对投入的需求水准。
中国和印度等发展中经济体正面临严重的水资源短缺,中国生活着全球近五分之一的人口,但仅占世界可再生淡水资源的6%。对水资源的需求增加了人口,并为水处理厂净化水提供了机会。无烟煤是常用的过滤材料。无烟煤具有高硬度和高碳含量的独特性能,使其持久且不易破碎,使其成为高效的过滤介质。
其颗粒结构使其具有较大的表面积,可吸附铁、锰和水源中常见的其他污染物等杂质。随着许多地区的用水需求持续增加,无烟煤成为水处理解决方案中可靠且有效率的工具。由于其耐用性和多功能性,它是确保水纯度的有用物质,为世界各地社区的福祉做出贡献。
中国、日本、印度、韩国等主要经济体在亚太地区占据主导地位。一些成长最快的新兴经济体来自该地区,例如东南亚国协。中国每年生产粗钢约10亿吨,占全球钢铁产量的一半以上。
中国在煤基高炉(碱性氧气转炉)中占主导地位,主要使用煅烧无烟煤。此外,宝钢集团、河钢集团、首钢集团等主要企业均位于中国。在该国,钢铁主要用于基础设施和房地产。
印度是世界第二大钢铁生产国。 2013财年,粗钢产量12532万吨,成品钢产量12129万吨,当年人均钢材消费量86.7公斤。各行业对工业应用的需求旺盛,使该地区成为煅烧无烟煤消费和需求的可行地点。
气相无烟煤(GCA)比传统无烟煤具有更高的碳含量和相对更高的导热性和导电性。根据需要控制这种类型的烧製以实现 1250μΩm 至 1450μΩm 的低电阻率。气锻无烟煤 (GCA) 与电锻无烟煤 (ECA) 混合使用,以优化成本和性能。
是製造碳电极糊的主要原料。其他用途包括钢厂的钢包、熔炉、保温炉和高炉作为增碳材料、碳添加剂、补料材料、喷射碳和碳发泡材。
其他应用包括电动式钢炉、水过滤、造船除锈、碳材料的生产。由于其在如此多样化的工业部门中的使用,预计在预测期内燃气无烟煤的使用和需求将会增长。
The calcined anthracite market is expected to grow at a CAGR of 3.5% during the forecast period (2024-2029).
The main factor driving the calcined anthracite market is the demand from increased demand for steel as it is used in decarburizing in ladle and blast furnaces in steel mills. Steel is a material of high tensile strength and low cost, it is the most commonly manufactured material in the world. It is used in buildings, as concrete reinforcing rods, bridges, infrastructure, tools, ships, trains, cars, bicycles, machines, machinery parts, electrical appliances, furniture, and other types of equipment.
Anthracite is suitable as a carburizing agent in iron foundries for grey cast iron, cast steel, and in steel works. When used as the carburizing agent, anthracite is calcined at approx. 1,400°C and cleaned thermally.
Electrically calcined anthracite (ECA) is produced by calcining anthracite at from 1800 to 2200 °C in an electric furnace. It has a higher carbon content and higher thermal and electrical conductivity. Its lower moisture, volatile, and sulfur content makes it suitable for manufacturing carbon electrode paste.
Calcined anthracite has a high carbon content. The calcination process reduces its volatile matter, enhancing the coal's stability and purity. Calcined anthracite coal finds use in various industrial processes where an increase in carbon content is required. Different grades of anthracite coal have different properties. Standard-grade anthracite has moisture of 15%, volatile matter to be at 10%, and fixed carbon at 73% minimum. Similarly, Ultra high-grade anthracite has a moisture content of 9%, ash (dry basis) of 10% maximum, and fixed carbon to be at 82% minimum.
Calcined anthracite coal mainly used in steelmaking, it improves the carbon content in steel-making and ductile iron foundry. It has high carbon and low sulfur with a stable effect.
Calcined anthracite has its application in the electric arc furnace (EAF), way of steel production. According to the World Steel Association, EAF-based steel production accounts for approximately 26% of the global output. Anthracite is usually used as a source of carbon.
With the growing economic development around the world, the demand for steel and iron has grown. Steel is the basic component of the construction of roads, buildings, ports, stations, etc. India has become one of the largest makers of highway construction in the world. Highway construction in India increased at a CAGR of 5.3% between FY14-FY23. India constructed 10,457 km of highways in FY22. In FY23, the figure was at 10,331 km. All these road constructions needed the required steel as an important input in the making, which would relatively increase the demand for calcined anthracite for the making of steel.
Further, in the United States, total construction spending was 1,882,199 in January 2023 to 2,087,508 (millions of dollars), according to the Federal Reserve Bank. This shows the level of demand for the input material in the sector.
Growing economies like China and India are facing serious water scarcity, nearly one-fifth of the world's population lives in China, but having only 6 percent of global renewable freshwater resources. The demand for water resources has enlarged the population giving opportunities for water treatment plants to be used for the purification of water. Anthracite is a commonly used filtering media. It has a unique property of hardness and high carbon content contributes to its longevity and resistance to breakdown for an efficient filtration medium.
The granular structure makes it suitable for the large surface area for the adsorption of impurities, such as iron, manganese, and other contaminants commonly found in water sources. As the water demand continues to rise in many regions, anthracite would be a reliable and efficient tool in the water treatment solution. Its durability and versatility make it a useful substance for ensuring the purity of water supply, contributing to the well-being of communities around the world.
The major economies like China, Japan, India, and South Korea dominate the Asia-Pacific region. Some of the fastest-growing emerging economies are from this region such as ASEAN countries. China produces about 1 billion tons of crude steel annually, which is more than half of the world's steel production.
China dominates coal-based blast furnaces-basic oxygen furnaces, where calcined anthracite has been predominantly used. Additionally, several key players like Baosteel Group, Hesteel Group, and Shougang Group are based in China. Steel has several applications in the country majorly in infrastructure and real estate in the country.
India is the second largest producer of steel in the world. With production of crude steel and finished steel stood at 125.32 MT and 121.29 MT, respectively, in the FY23, the country has per-capita consumption of steel stood at 86.7 kgs in the same year. The region has a vibrant demand for industrial applications from various sectors making it a viable place for the consumption and demand of calcined anthracite.
Gas-calcined anthracite (GCA) has a higher carbon content and relatively higher thermal and electrical conductivity than conventional anthracite coal. This type of calcining is controlled to achieve a lower electrical resistivity ranging from 1250µΩm to 1450µΩm, depending upon the need. Gas-calcined anthracite (GCA) is used to blend with electrically calcined anthracite (ECA) for cost and performance optimization.
It is the main raw material for manufacturing carbon electrode paste. Other applications include steel mill ladles, melting, holding, and blast furnace usage as carbon raisers, carbon additives, recarburizers, injection carbon, and carbon foaming material.
Further applications include electric steel ovens, water filtering, rust removal in shipbuilding, and the production of carbon material. Due to this multiple usage across the different industry segments, the usage and demand for the gas calcined anthracite would grow during the forecast period.
