Problems

Smelting optimisation

Non optimal control
of coal addition to ore

Ni content in metal and slag deviate from expected ranges

Lab tests provide only fragmented and imprecise info too late

Unstable ore and coal properties

Application for nickel content analysis and coal setpoint control

Solution

Application allows adjustment of the coal set point to stabilise Ni content in metal and reduce slag losses

Data-based ML prediction model provides Ni content in metal and slag 14 hours in advance — the standard time of a full manufacturing cycle

Result

Ni content
in slag
