COAL HANDLING SAFETY
If the mill is restarted without first removing the hot coal, an explosion can occur when particles are suspended and exposed to the in-rushing combustion air. Even in routine mill shutdowns, there is a danger that any residual coal left within the mill will oxidise, and may explode as the mill is restarted.

What happens if stainless/carbon welding was done with E70xx
It was a huge Thyssen Krupp Stacker / Reclaimer that was being constructed at a Coal Loading Facility. The tank was 3 metres square and was made of 6 mm 316 stainless steel. For some reason it had been painted blue so when the welder was requested to add a 2" coupling to the side of the tank he just presumed it was mild steel.

Steel and raw materials
Coal and coke Coking coal is a key raw material in steel production. As iron occurs only as iron oxides in the earth's crust, the ores must be converted, or 'reduced', using carbon. The primary source of this carbon is coking coal. Coke, made by carburising coking coal (i.e. heating in the absence of oxygen at high
