The metallurgical industry is a multi-faceted industry involving metal smelting, metal processing, and the manufacture and application of metal materials. It is a complex industry that covers the extraction of mineral resources, metal smelting, metal processing, and the manufacture and application of metal materials. First, the metallurgical industry includes the extraction of mineral resources, which is the foundation and precondition of the industry — including mining, sand extraction and quarrying. Second, the metallurgical industry includes metal smelting, the core of the industry, comprising melting, refining and alloy preparation. Third, it includes metal processing — forging, die forging, stamping, welding and so on. Finally, it includes the manufacture and application of metal materials, such as castings, forgings, profiles, pipes and welding materials. In summary, the metallurgical industry covers the extraction of mineral resources, metal smelting, metal processing, and the manufacture and application of metal materials. It is a complex, multi-disciplinary industry whose development requires the integrated application of multiple technologies.

Valves used in the mining and metallurgical industry operate under severe conditions. Poor valve sealing performance, together with corrosion and wear in the production process, causes pipeline aging and valve wear, requiring frequent repair. As a result, short valve service life and high repair frequency lead to long downtime. The mining industry therefore needs new valve solutions to help make mining and smelting processes safer and more efficient. Using advanced design and simulation software — including computational fluid dynamics (CFD) and ANSYS finite element analysis (FEA) — SUFA valves can simulate product flow, mechanical behavior and wear conditions. Knife gate valves, metal-seated ball and butterfly valves and other products developed and optimized with these advanced technologies significantly improve overall product performance and help achieve long production runs in process automation. The valve solutions SUFA provides for the mining industry help improve safety conditions, improve the working conditions of process pipelines, upgrade customer facilities, extend valve service life and reduce downtime caused by maintenance.

The metallurgical industry is the industrial sector engaged in the exploration, mining, beneficiation, smelting and rolling of metal ores into finished products. It comprises two major categories: ferrous metallurgy (i.e., the iron and steel industry) and non-ferrous metallurgy. Mining refers to the extraction of naturally occurring minerals — solids (such as coal and ores), liquids (such as crude oil) or gases (such as natural gas). It includes underground or surface extraction, the operation of mines, and generally all ancillary work performed at or near the mine site for the purpose of processing raw materials, such as crushing, grinding, beneficiation and treatment, as well as preparations required to make raw materials marketable. It does not include the collection, purification and distribution of water, nor geological prospecting and construction activities. The mining and metallurgical industry generally refers to the extraction and utilization of metallic or non-metallic mineral resources.
