Temperature profile across melted zone

In order to determine the temperature profile across the melted zone of each run, a separate, identical run is carried out under the exactly same conditions. The reproduceability of the experimental runs was checked by comparing the separation results of both runs. A copper-constantan thermocouple is situated in the casted sample by inserting it during the casting, to measure the temperature of the melted zone while it is passing the thermocouple. 

A second crosswise AT error is Iht variable temperature profile of the combustion gases across the furnace depending on the firing rate. With only one temperature measurement in a zone, the zone setpoint must be conservative to prevent rapid scale melting in any part of the zone hence, productivity is sacrificed. Modern burners...
