With an annual production capacity of 200,000 tons of special alloys, its products are widely used in the automotive, aerospace, and petrochemical industries.<\/li>\n<li>The project involves the technical upgrade of the workshop cooling recirculating water system with a designed treatment capacity of 5,000 m\u00b3\/d, the closed-loop recirculating water system upgrade with a designed treatment capacity of 24,000 m\u00b3\/d, and the newly added closed-loop recirculating water system with a designed treatment capacity of 72,000 m\u00b3\/h.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Key Technical Challenges<\/strong><\/p>\n<ul>\n<li>The upgrade work must be carried out without interrupting steelmaking production, requiring parallel construction involving the reuse of existing equipment, replacement of outdated units, and installation of new systems across multiple batches. This imposes extremely high demands on construction planning, schedule control, and production assurance.<\/li>\n<li>The project must simultaneously meet the water quality stabilization, corrosion and scale prevention, and operational efficiency requirements of recirculating water systems of varying scales, making process commissioning and system integration particularly challenging.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Process Flow<\/strong><\/p>\n<ul>\n<li>5,000 m\u00b3\/d workshop cooling recirculating water: Cooling recirculating water \u2192 High-Speed Filter (replacement) \u2192 Triple Collection Tank (replacement with high-efficiency sedimentation) \u2192 Integrated Water Purifier (reused) \u2192 Recirculating Service Tank<\/li>\n<li>24,000 m\u00b3\/d closed-loop recirculating water: Closed-loop recirculating water \u2192 Mechanical Filter (replacement) \u2192 Automatic Resin Softener (replacement) \u2192 Return to Raw Water<\/li>\n<li>72,000 m\u00b3\/d closed-loop recirculating water (newly added): Closed-loop recirculating water \u2192 Mechanical Filter (newly added) \u2192 Electrochemical Water Treatment Unit (newly added) \u2192 Return to Raw Water<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter wp-image-1904\" src=\"https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/1772271212183566.jpg\" alt=\"\" width=\"1000\" height=\"750\" srcset=\"https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/1772271212183566.jpg 1267w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/1772271212183566-300x225.jpg 300w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/1772271212183566-1024x768.jpg 1024w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/1772271212183566-768x576.jpg 768w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/1772271212183566-16x12.jpg 16w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-2132\" src=\"https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5.jpg\" alt=\"\" width=\"1000\" height=\"750\" srcset=\"https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5.jpg 1706w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5-300x225.jpg 300w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5-1024x768.jpg 1024w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5-768x576.jpg 768w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5-1536x1152.jpg 1536w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/2-5-16x12.jpg 16w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-2134\" src=\"https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-scaled.jpg\" alt=\"\" width=\"1000\" height=\"750\" srcset=\"https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-scaled.jpg 2560w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-300x225.jpg 300w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-1024x768.jpg 1024w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-768x576.jpg 768w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-1536x1152.jpg 1536w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-2048x1536.jpg 2048w, https:\/\/www.mingyuhb.com\/wp-content\/uploads\/2026\/06\/3-3-16x12.jpg 16w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>","protected":false},"featured_media":1904,"parent":0,"menu_order":14,"template":"","format":"standard","categories":[10],"class_list":["post-1903","case","type-case","status-publish","format-standard","has-post-thumbnail","hentry","categories-other-wastewater"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.mingyuhb.com\/en\/wp-json\/wp\/v2\/case\/1903","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.mingyuhb.com\/en\/wp-json\/wp\/v2\/case"}],"about":[{"href":"https:\/\/www.mingyuhb.com\/en\/wp-json\/wp\/v2\/types\/case"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.mingyuhb.com\/en\/wp-json\/wp\/v2\/media\/1904"}],"wp:attachment":[{"href":"https:\/\/www.mingyuhb.com\/en\/wp-json\/wp\/v2\/media?parent=1903"}],"wp:term":[{"taxonomy":"categories","embeddable":true,"href":"https:\/\/www.mingyuhb.com\/en\/wp-json\/wp\/v2\/categories?post=1903"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
