The result is the display of bright red, glowing liquid iron droplets that pour down the furnace and collect, forming a stream of high-purity iron that can be directly used for casting or &#8220;one-step steel production.&#8221; This signifies an increase in iron production speed by 3,600 times or more.  <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">According to researchers, this new method works especially well for low- or medium-grade iron ores, which are abundantly found in China.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">Existing iron production methods are heavily dependent on high-grade iron ores, and China imports a large amount of these ores from Australia, Brazil, and Africa.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">According to calculations by Zhang and his colleagues, this new technology could improve energy efficiency in China&#8217;s steel industry by more than a third. By completely eliminating the need for coal, this technology could also bring the steel industry closer to the desired goal of &#8220;near-zero carbon dioxide emissions,&#8221; according to Zhang&#8217;s team. <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">China&#8217;s steel production capacity is currently greater than the combined output of the rest of the world. This advantage has given China an edge in key industries such as high-speed rail, shipbuilding, and automobile manufacturing. <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">However, its reliance on blast furnace melting processes, which require large amounts of coke derived from coal, is a major barrier to achieving China&#8217;s ambitious carbon reduction goals.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">One of the major technical challenges in realizing flash ironmaking is the lance that sprays the iron ore. The iron ore must be dispersed in a high-temperature tower with high reduction capability and a large surface area to initiate the explosion. <\/span><\/p>\n<p><a href=\"https:\/\/steelworldreview.com\/wp-content\/uploads\/2025\/02\/%DA%86%DB%8C%D9%86-%D9%85%D8%AD%D8%AA%D9%88%D8%A7.jpg\"><img decoding=\"async\" class=\"aligncenter size-full wp-image-5598\" src=\"https:\/\/steelworldreview.com\/wp-content\/uploads\/2025\/02\/%DA%86%DB%8C%D9%86-%D9%85%D8%AD%D8%AA%D9%88%D8%A7.jpg\" alt=\"\" width=\"640\" height=\"360\"><\/a><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">Zhang&#8217;s team has developed a vortex lance with exceptional uniform distribution performance, capable of injecting 450 tons of iron ore particles per hour. A reactor equipped with three of these lances can produce 7.11 million tons of iron annually. According to the paper, this lance &#8220;has now entered commercial production.&#8221;<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">Zhang&#8217;s journey with flash melting technology began in the 1970s when he applied it for large-scale copper production. His work earned him the first-place National Science and Technology Progress Award in 2000 and led to his selection to the Chinese Academy of Engineering in 2003. <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">Today, China&#8217;s copper consumption accounts for nearly 60% of global production, a testament to Zhang&#8217;s lasting impact on the industry.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">While the idea of using this process for iron production originated in the United States, it was Zhang&#8217;s team that invented a flash melting technology capable of directly producing liquid iron. They received a patent for it in 2013 and spent the next decade refining the method. <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">&#8220;Laboratory and pilot tests have proven that this process is feasible,&#8221; Zhang wrote. According to government statistics, the success rate for new technologies that have passed pilot testing in China is over 80%. <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">For most of recorded history, China has been a leader in iron and steel production. As the Tang Dynasty poet, Li Bai (701-762), once described, the large iron-producing furnaces in an iron-making city in what is today Anhui Province lit up the night sky. <\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"font-weight: 400\">According to estimates by American historian Robert Hartwell, during the Song Dynasty in the 11th century, China&#8217;s iron production reached 150,000 tons per year \u2013 a figure that was not achieved in all of Europe until after the beginning of the Industrial Revolution in the 18th century.<\/span><\/p>\n<p style=\"text-align: justify\">\n<p style=\"text-align: justify\"><strong>Steel World Review<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new method for producing iron is not only faster and cheaper, but according to Chinese researchers, it is also better for the environment.
