Core Responsibilities

Primary Functions

Design and develop detailed refractory lining specifications for new installations, retrofits, and repairs of high-temperature equipment, including furnaces, ladles, tundishes, and kilns.
Conduct thorough material selection processes, evaluating various refractory products (bricks, castables, plastics, ceramics) based on thermal properties, chemical resistance, and mechanical strength for specific process applications.
Create and manage detailed engineering drawings, installation procedures, and quality control plans for all refractory projects, ensuring compliance with industry standards and best practices.
Provide on-site technical supervision and expert guidance during refractory installation, dry-out, and heat-up procedures to ensure workmanship meets design specifications and quality standards.
Develop and implement comprehensive inspection and preventative maintenance programs to monitor the condition of refractory linings, predict wear patterns, and schedule proactive repairs to minimize unplanned downtime.
Perform root cause analysis (RCA) on premature refractory failures, utilizing techniques like post-mortem sample analysis, thermal modeling, and process data review to identify causes and implement corrective actions.
Manage the full lifecycle of refractory projects, from initial scope development and budgeting to vendor selection, contract negotiation, and final commissioning.
Collaborate closely with production and maintenance teams to coordinate refractory repair schedules, ensuring minimal disruption to plant operations while maximizing lining performance.
Evaluate and qualify new refractory materials and installation technologies through laboratory testing and in-plant trials to drive continuous improvement in performance, cost-effectiveness, and safety.
Prepare detailed cost estimates, capital expenditure requests (CAPEX), and project justifications for refractory-related initiatives, presenting findings to senior management.
Maintain a comprehensive database of refractory performance, tracking key metrics such as lining life, consumption rates, and cost per ton of product to inform future design and purchasing decisions.
Develop and deliver technical training programs for maintenance crews, operators, and contractors on proper refractory handling, installation techniques, and inspection criteria.
Act as the primary technical liaison with refractory material suppliers and installation contractors, managing relationships and ensuring accountability for product quality and service delivery.
Utilize thermal and stress analysis software (e.g., FEA) to model and predict the behavior of refractory linings under various operating conditions, optimizing designs for thermal efficiency and structural integrity.
Champion safety protocols for all refractory work, including hot work, confined space entry, and handling of ceramic fibers, ensuring all activities comply with company and regulatory EHS standards.
Develop and oversee standardized dry-out and heat-up schedules for new and repaired linings to prevent thermal shock and ensure optimal material curing and long-term performance.
Lead refractory tear-out inspections, meticulously documenting wear patterns, failure mechanisms, and remaining lining thickness to provide critical data for future repair scopes and design improvements.
Review and approve vendor proposals, technical submittals, and quality assurance/quality control (QA/QC) documentation to ensure all purchased materials and services meet project requirements.
Stay current with advancements in refractory technology, materials science, and industry best practices by attending conferences, participating in technical committees, and networking with industry peers.
Prepare and present detailed technical reports, project summaries, and performance analyses to plant leadership, translating complex engineering data into clear, actionable business insights.
Manage the inventory of refractory spare parts and materials, optimizing stock levels to ensure availability for planned and emergency repairs without incurring excessive holding costs.

Secondary Functions

Support ad-hoc technical inquiries and troubleshooting requests from operations and maintenance teams regarding thermal processing issues.
Contribute to the plant's long-term capital planning and asset integrity strategy, specifically for high-temperature equipment.
Collaborate with process and quality departments to investigate how refractory performance impacts final product quality.
Participate in cross-functional continuous improvement initiatives (e.g., Kaizen events) focused on energy reduction, yield improvement, and operational stability.
