Steel Mill Operating Recommendations

Steel Mill Operating Recommendations
Caterpillar recommends that Steel Mill machines be exposed to hot slag for less than 15 minutes each hour to allow for adequate cooling time between cycles. Typically, two machines per furnace and a backup machine for the site provide the best uptime. The timing, frequency and duration of the work and cooling cycles varies by job site, but exceeding the recommended exposure time will prevent the machine from meeting expected performance levels.
