Our Service
Comprehensive Service System – From Needs Assessment to Ongoing Operational Support
As a full‑industry‑chain service provider for submerged arc furnaces (SAFs), we have built a "full‑lifecycle service matrix" that covers four key pillars: equipment manufacturing, electrical automation, environmental protection and emission reduction, and refractory materials. This enables us to offer customers one‑stop solutions throughout the entire project lifecycle.
1. Pre-sales Consulting and Solution Design
① Expert‑level Needs Assessment: We dispatch a technical team consisting of process engineers, mechanical engineers, electrical automation experts, and environmental engineers to conduct on‑site operating condition audits covering raw material characteristics, energy consumption data, emission indicators, and more. We then deliver the Energy Efficiency Assessment Report for the Submerged Arc Furnace System and the Feasibility Analysis for Technical Upgrades.
② Customized EPC Solution Development: We develop furnace structure designs based on 3D modeling (including thermodynamic simulation analysis). Tailored to the client's specific conditions, we deliver a full‑plant engineering design package (covering civil works), mechanical equipment proposals, electrical control system solutions, integrated environmental compliance packages (with optional modules for flue gas purification, dust recovery, and noise control), as well as recommendations for refractory material selection.
2. Implementation Support System
① Refined Project Management: We employ an ERP system to implement "four‑control management" covering schedule, quality, cost, and safety. A bilingual (Chinese‑English) Project Progress Report is submitted weekly. Dynamic management is carried out based on site conditions.
② Critical Equipment Manufacturing Supervision: We open up factory and on‑site testing of core equipment (e.g., electrode systems) for client participation, and provide quality certification documents including NDT (non‑destructive testing) reports and process control inspection reports.
③ Installation and Commissioning Support: We deploy a "1+3" on‑site service team (comprising 1 project manager and mechanical, electrical, and automation engineers) to conduct a 72‑hour continuous load test, including energy efficiency data collection.
3. After‑sales Continuous Value Creation
① Smart Operation and Maintenance Services: We provide a remote diagnostic system that can be integrated with the client's DCS (Distributed Control System) for real‑time monitoring. A quarterly Equipment Health Analysis Report is submitted.
② Specialized Technical Support: We offer a refractory material maintenance program, including annual furnace lining surveying services, as well as annual environmental equipment inspection services to ensure sustained compliance with emission standards.
③ Value‑Added Service Package: We offer an annual energy efficiency optimization service (including process parameter tuning), a joint spare parts stocking plan (which grants strategic customers priority allocation of emergency spare parts), and operator certification training (with issuance of position qualification certificates).
④ Rapid Response Mechanism: We offer a 7×24 technical hotline (with video remote guidance support), a commitment to on‑site arrival within 48 hours domestically (72 hours for border areas), and a dedicated customer service archive that fully records all equipment lifecycle data.
