Steel and foundry equipment, electric arc furnaces, ladle refining, continuous casters, rolling mills, and induction furnaces.
Steel plants and foundries operate at the highest-consequence end of heavy industry. Molten metal is unforgiving. An EAF electrical fault can be catastrophic. A cast-house spill destroys equipment and injures people. Every task in this category has to start with the safety plan, because improvisation at this temperature is how people die.
Never be near molten metal without full radiant-heat PPE. Never let water contact molten metal: the resulting explosion is instantaneous and severe. Always have an escape route before starting any task on a hot vessel. Never trust a ladle crane or a charging crane without verifying the operator knows you are there. These are not suggestions.
Electrode regulation is a balance of tip position, arm hydraulics, contact shoe condition, and transformer tap. When an EAF is not holding a stable arc, the usual suspects are worn contact shoes, worn mast bushings, or hydraulic leaks on the arm regulator. Diagnose on a cool furnace. Do not improvise during a heat.
Casters run continuously for weeks and then need major PM.
Ladle cranes are the highest-risk cranes in the plant. A ladle move is not the time to be cleaning, inspecting, or repairing anything nearby. Clear the area until the move is complete. Rigging is inspected before every shift, without exception. Load-test records have to be current. This industry does not forgive rigging mistakes.

Deeper explainers and background reading for technicians working in steel, metals & foundry.
80% of hydraulic failures come from just 3 causes: contaminated fluid, overheating, or internal leaks. Stop guessing, use this step-by-step diagnostic sequence to find the root cause in minutes, not hours.
Electrical faults cause 30% of unplanned downtime. This systematic fault finding guide, visual inspection → voltage checks → component isolation → testing, helps you diagnose faults in minutes, not hours.
Bearings are the most commonly replaced component in industrial machinery. Yet 16% of premature bearing failures come from improper installation: wrong fit, contamination during mounting, or inadequate lubrication at startup. This guide covers the full process from selection to run-in.
Preventive maintenance replaces the 'run it until it breaks' approach with scheduled inspections and part replacements. Plants that run a solid PM program see 25-30% fewer emergency work orders within the first year. Here is how to build one that sticks.
