Heat Transfer during the Sintering Process

The fundamental study on the sintering of iron ores-II

Abstract

By charging a small sintering pan with Goa hematite or Larap magnetite as raw materials, the speed of heat transfer in non-sintered or sintered layers Were measured and the following results were obtained:
i) Difference between the heat front speed in non-sintered layers, which were very slow, and the flame front speed were more increased with increase of the air flow through the bed.
ii) There was a small difference between the heat front speed in sintered layers, which were more rapid than that in non-sintered layers, and the flame front speed.
iii) When the difference between the heat front speed in non-sintered layers and the flame front speed were large, the temperatures of combustion zones rose slowly. On the contrary, in the case when that difference between the heat front speed in sintered layers and the flame front speed were large, the temperature of combustion zone dropped slowly.
