Sintering the welding together of small particles of metal by applying heat below the melting pointThe process may be used in steel manufacturing—to form complex shapes to produce alloys or to work in metals with very high melting points In a steel sintering plant a bed of powdered iron ore mixed with coke or anthracite is ignited by a gas burner and then moved along a traveling grateQ sintering of iron ore 1 INTRODUCTION 40 to 50 iron ore becomes under size which may create pollution in the plant of the mine site For the utilization of the variable ore it is necessary to agglomerate the fines into the required size for charging in the blast furnace Agglomeration is the size incensement process of the fines ore
