The induction furnace consists basically of a crucible, inductor coil, and shell, cooling system and tilting mechanism.The crucible is formed from refractory material, which the furnace coils is lined with.This crucible holds the charge material and subsequently the melt.
Refractory materials for furnace are a kind of inorganic nonmetallic materials with various excellent performances on application for industrial furnace such as glass furnace, cement kiln, ceramic kiln and coke oven.There are various high temperature refractory materials for refractory furnace.
The heart of the midrex process is the midrex shaft furnace.As a key component of the midrex direct reduction process, the midrex shaft furnace is the most flexible and versatile reduction vessel for dri producers.The midrex shaft furnace can use natural gas or a syngas from coal or coke oven gas as its.
Silica the pure silica fuses at a very high temperature, viz., 1713c, but when heated in contact with basic substances it forms silicates, some of which fuse easily.Therefore, the presence of bases in silica to be used as refractory materials is to be guarded against.Silica occurs as quartzite, dinas rock and ganister.

A method and apparatus for reducing iron oxides using microwave heating in a furnace chamber which is sealed against the entrance of air reduces the energy required and produces a low temperature reduction and allows the recovery of combustible synthetic gas as a byproduct of the process.Avoidance of the reduction of sulfur, phorphorus and silica is also insured, as is the need to reduce the.
Morris, in encyclopedia of materials science and technology, 2001.3 kiln processes.The rotary kiln is a revolving horizontal cylinder comprising a shell with an internal refractory lining.The furnace is inclined at an angle of 34 degrees from the horizontal, so the burden travels through the furnace by rotation and gravity.
