In the present study, three batch compositions were prepared utilizing iron ore tailing in the range of 4560 wt%, clay 2535 wt% and feldspar 1520 wt%. The compacts were heated in the temperature range of 1100o1150oC. All the samples heated at 1150oC possess very high cold crushing strength (>150 MPa) and high flexural strength (>60 MPa) with less than % water absorption.
Raw Materials The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.

Iron Production Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron .
The raw materials are brought to the top of the blast furnace via a skip car powered by winches or conveyor belts. There are different ways in which the raw materials are charged into the blast furnace. Some blast furnaces use a "double bell" system where two "bells" are used to control the entry of raw material into the blast furnace.
Jun 01, 2017· Select the high density, low water absorption of raw materials, a reasonable level of preparation is the key to make low porosity refractory brick. Refractory brick is made with 50% soft clay and 50% hard clay clinker according to certain granularity requirements. After molding and drying, firing under high temperature of 1300 ~ 1400 ℃.
