Core Responsibilities

Primary Functions

Operate and monitor blast furnaces, cupola furnaces, induction furnaces, electric arc furnaces (EAF) or other melting equipment, performing charge calculations and sequencing to achieve target chemistry and melt schedules while minimizing energy consumption.
Prepare and stage charge materials, including pig iron, scrap, ferrous alloys, fluxes and coke, ensuring correct material handling, weighing and batching to meet specified metallurgical recipes and production plans.
Maintain precise temperature control during melts using thermocouples and infrared pyrometers, interpret temperature trends and adjust fuel, oxygen, and power inputs to maintain melt quality and reduce rework.
Control slag formation and removal, perform skimming and slagging operations safely, and coordinate slag handling to minimize melt contamination and downstream casting defects.
Perform tapping and ladle operations: drain molten metal into ladles, manage ladle treatments (deoxidizers, alloying additions), and ensure safe transfer to casting or holding areas.
Conduct routine in-process sampling and basic metallurgical testing (spectrometer pulls, chemical sampling, boil tests) and work with lab personnel to validate composition and mechanical properties against customer specifications.
Read and interpret production orders, metallurgical specifications and job work instructions; adjust furnace parameters and alloy additions to meet chemical and physical product requirements.
Follow standard operating procedures (SOPs) and safe work permits for hot work, confined spaces, lockout/tagout (LOTO) and hot tapping; ensure all safety interlocks and emergency shutdown procedures are functional.
Start up and shut down melting equipment according to manufacturer and plant procedures, performing pre-start checks and documenting machine conditions, alarms and observations in shift logs.
Monitor and interpret process control displays, PLC/HMI readouts, and instrumentation to identify deviations, initiate corrective actions and notify supervision of persistent process anomalies.
Coordinate with maintenance and reliability teams to request, prioritize and support preventive and corrective maintenance on furnaces, conveyors, ladle cars and other molten metal handling equipment.
Manage and control furnace atmosphere and gas flow (oxygen, natural gas, coke oven gas) to optimize combustion efficiency and control oxidation/reduction conditions in the melt.
Maintain accurate production and quality records, including melt reports, alloy usage, temperature logs and incident reports, to ensure traceability and compliance with customer and regulatory requirements.
Implement quality control measures to minimize inclusions, porosity and other casting defects; inspect molds, pouring systems and gating to ensure proper flow and solidification.
Train and mentor junior operators and new hires on safe furnace operation, material handling techniques, quality checkpoints and emergency procedures.
Enforce environmental controls, including emissions monitoring, dust/particulate control and proper disposal of slag and refractory waste in compliance with environmental permits and regulations.
Participate in continuous improvement and lean manufacturing initiatives (5S, Kaizen, AM, TPM) to reduce cycle time, scrap, energy usage and overall cost per ton.
Respond to furnace upsets, alarms and emergency conditions (overtemperature, oxygen/hydrogen spikes, refractory breach) by executing safe shutdown procedures and coordinating emergency response.
Inspect and maintain refractory linings and furnace seals, report signs of wear, thermal cracking or leaks and support refurnacing activities with planning and skilled craftsmen.
Operate auxiliary equipment including crucible handling, ladle transfer cars, tundish heaters, pouring machines and automated gating systems to ensure smooth cast operations.
Ensure proper use and maintenance of personal protective equipment (PPE), heat shields and respiratory protection during all furnace and pouring activities.
Support product changeovers and recipe updates to accommodate new alloys, trial melts or customer-specific metallurgies while documenting process adjustments and outcomes.
Communicate effectively with downstream casting, molding and finishing teams to synchronize melts with production schedules and reduce wait time or reheat cycles.
Maintain housekeeping in the melting and pouring areas, control slip/trip hazards and ensure safe storage of combustibles and flammable materials near heat sources.
Support inventory control of alloys, fluxes and refractory spares; perform cycle counts and flag low-stock conditions to buyers and planners.

Secondary Functions

Assist in root-cause investigations for quality escapes and production incidents; provide operator observations, data logs and potential corrective actions.
Support training programs and create or update operator SOPs and process checklists.
Participate in safety committees and audits; implement corrective actions from safety and environmental inspections.
Collaborate with metallurgists and process engineers on pilot melts, R&D trials and new product introductions.
Perform minor preventive maintenance tasks (lubrication, sensor cleaning, basic electrical checks) and escalate complex repairs to maintenance.
Help coordinate shift handovers with clear, written documentation of open issues, pending repairs and in-flight melts.
Participate in energy management programs and suggest operational changes to reduce fuel and electricity consumption.
Support load-in and load-out logistics by coordinating crane, forklift and rail operations for raw materials and finished castings.
