Alibaba offers 180 rotary kiln furnace iron products. About 12% of these are industrial furnace. A wide variety of rotary kiln furnace iron options are available to you, such as melting furnace, heat treatment furnace, and sintering furnace.
Rotary Kilns. Industrial Rotary Kilns are primarily used in cement, lime, and iron ore processing. These furnaces use direct flame-fired heating methods to remove volatile compounds, instigate chemical reactions, and fuse powder into pellets. The material is rotated as it moves through the kiln, in order to evenly heat said material without
Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
The rotary drum furnace's heated area is enclosed by the kiln body, an outer housing, and a refractory lining. The furnace body and housing are made of steel or heat-resistant sheets. The refractory lining often consists of heat-resistant fiber insulation that allows surface temperatures below 60 °C.
Rotary kiln or furnace Gordon ( Rotary kiln ) devices that include tubes of iron or steel inside with refractory materials and refractory such as cement or brick insulated and slowly revolves around the horizon and the gentle slope period They do. Lime and dolomite rotary kilns are the most widely used rotary kilns after cement kilns.
Ported kiln operation. By injecting air under the bed of pellets in the rotary kiln, complete oxidation can occur in magnetite pellets prior to the annualar cooler. This patented development by Metso, in addition to lowering fuel consumption, significantly improves pellet quality.
A muffle rotary kiln is indirect combustion kiln, it applies to high grade iron ore and mill scale, in the condition of reducing atmosphere and high temperature, the iron ore is reduced and volumn shrink, to become high density of DRI ( HDDRI ).
Ironmaking in Rotary Hearth Furnace. Ironmaking in the rotary hearth furnace (RHF) is a direct reduction process which utilizes non-coking coal for the reduction of iron ore. The RHF is the process reactor which consists of a flat, refractory hearth rotating inside a stationary, circular tunnel kiln.
erection. The SL-RN process also uses rotary kiln for reducing iron ore. The plant, as shown in Fig. 2, essentially consists of raw material handling and preparation systems, rotary kiln with heat-ing arrangements for reduction of iron oxide, kiln for cooling the reduced material and the facilities for separating sponge iron from char
The inclination and the rotary motion of the kiln ensures that the raw materials moves from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.

Hot sponge iron from rotary kiln shall be smelted directly by continuously charging into smelting reduction furnace. The smelting furnace itself is equipped with stoves to preheat the hot blast air.

In India there are many small rotary kiln furnaces producing DRI, known locally as sponge iron, using coal as energy and reductant source. Some of the sponge iron plants are captive to steel mills, but there is a significant domestic merchant market, India producing 57% of its crude steel in electric arc furnaces
DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore lumps, or fines. The reduction takes place using gaseous reductants (CO + H
The inclination and the rotary motion of the kiln ensures that the raw materials moves from the feed end to the discharge end of the kiln and during this movement the actual reduction of iron ore to iron takes place. The material discharged from the kiln is taken to a rotary cooler for cooling and the cooled product is separated from the coal char.
The four horizontal rotary kilns are the heart of the reduction process. The residual char (carbon) remaining after the coal was heated is used to achieve the chemical reduction of iron oxide to iron. A number of chemical reactions occur in the kilns because coal and ironsand are not pure substances like laboratory chemicals.
In an Indurating Furnace, the pellets are loaded on to a travelling grate to a depth of approximately 3060cm where they are preheated (typically to 800- 9000C), before entering a higher temperature stage (around 1,200-1,3500C) which in some designs is a continuation of the travelling grate, and in others take the form of a rotary kiln.
Rotary kiln The final induration of the pellet is accomplished in a rotary kiln, wherein the principal heat transfer mechanism is radiation from the system's main burner. The process system is designed so that material transfer from the grate to the kiln occurs when the material on the grate is sufficiently preheated to have the requisite
