Driven by China’s long‑term rapid economic growth and steel demand, the iron and steel metallurgical sector has become an essential basic industry for national economy. It underpins industrialization and is a technology‑intensive, capital‑intensive, resource‑intensive and energy‑intensive industry. Energy saving, consumption reduction and resource conservation are major urgent subjects to be addressed in the metallurgical industry. The sector also faces retrofitting and upgrading of existing equipment and phasing‑out of backward facilities with high energy consumption and heavy environmental pollution. To elevate the steel industry to a higher development level with increasing emphasis on energy‑saving, environmental‑protection and product‑mix optimization, a large number of advanced equipment is required. Therefore, steel‑metallurgy valves enjoy huge market potential, and energy‑saving and emission‑reduction valve equipment bears even greater prospective market value.
