On November 8, the high-quality development conference of the vanadium-titanium wear-resistant casting industry was held in Yanbian County, Panzhihua City, Sichuan Province. The conference focused on the upgrading of the vanadium-titanium wear-resistant casting industry, innovative research and development, etc., and brought together more than 150 industry experts, industry elites, entrepreneurs, etc. to conduct in-depth discussions on the high-quality development path of the vanadium-titanium wear-resistant casting industry. At the meeting, Panzhihua signed 6 projects on site, with a total planned investment of 2.4 billion yuan.
Casting is an indispensable process link in the machinery industry and is related to the safety and stability of the equipment manufacturing industry chain and supply chain. Wear-resistant castings are an important component. Wear-resistant materials and their wear-resistant parts are mainly used in industries such as mining, metallurgy, building materials, electric power, construction, railways, ships, coal, chemicals, and machinery. They are key components and wearing parts of important equipment. Currently, with the development trend of major equipment such as crushing, grinding, excavation and pumping, the industry has increasingly higher requirements for the technology of wear-resistant castings, especially the wear-resistant life of large wear-resistant parts.
Panzhihua thrives on steel and is famous for its vanadium and titanium. Its titanium and vanadium resource reserves rank first and third in the world respectively. It is the world's number one vanadium product production base and the largest domestic and globally important full-process titanium industrial base. It is known as It is the “Vanadium and Titanium Capital of China”. The Honggenan mining area in Yanbian County, which is currently under development, has resource reserves of 3.256 billion tons. It is the vanadium-titanium magnetite deposit with the largest proven reserves, the most associated elements, and the highest resource potential value in my country.

At the meeting, the relevant person in charge of Panzhihua City introduced that Panzhihua, as a hundred-mile steel city and the capital of vanadium and titanium, has the resources, foundation, advantages, market and guarantee to develop the vanadium and titanium wear-resistant casting industry. It is the foundry industry in Southwest China. A new highland for the development of “building circles and strong links”.
High-quality cast iron rich in vanadium and titanium produced by Panzhihua vanadium-titanium magnetite smelting and titanium slag smelting has natural micro-alloying effect and is a rare raw material for foundry companies to manufacture high-end wear-resistant castings and forgings. The vanadium-containing cast iron produced Titanium castings have unique properties such as high strength, good toughness, wear resistance, and good heat resistance. The yield strength can be increased by more than 10%, the tensile strength can be increased by 8% to 15%, and the wear resistance can be increased by 20% to 40%. At present, Panzhihua city has a production capacity of 1.5 million tons of vanadium-containing titanium cast pig iron. It is not only large in quantity and high in quality, but can also be hot-delivered and hot-loaded nearby, which can effectively reduce production costs.

At present, Panzhihua City has built three major foundry industrial parks: the million-ton vanadium and titanium wear-resistant casting industrial park in Yanbian County, the million-ton southwest vanadium and titanium casting industrial park in Renhe District, and the vanadium and titanium high-tech zone casting function industrial park. In addition, major projects such as the upgrading of Panxi titanium concentrate into titanium chloride slag and high-end wear-resistant steel balls will soon be put into production in Panzhihua.
At the meeting, Panzhihua City signed on-site contracts for a 100,000-ton annual auto parts project, a 30,000-ton annual casting new material project, a graphite composite self-lubricating material and self-lubricating precision parts production base project, and an annual 500,000-ton centrifugal ductile cast pipe project. Project, 6 projects including an annual output of 80,000 tons of wear-resistant vanadium and titanium castings, and a 400-ton titanium alloy investment mold shell production line project, with a total planned investment of 2.4 billion yuan.
In recent years, Panzhihua City has relied on the performance advantages of natural vanadium-containing titanium in steel, the cost advantage of locally sourced raw materials, and the demand advantages of many surrounding mining companies, focusing on the vanadium-titanium wear-resistant casting industry to build a strong chain, introducing Merrill Lynch and other related There are more than 30 enterprises, from one project to project cluster, to the vanadium and titanium wear-resistant casting industrial park, and continue to promote the high-quality development of the high-end vanadium and titanium wear-resistant casting industry.
