At Adukia Industries, we produce sponge iron through the direct reduction of iron ore using carbon in the form of coal at approximately 1100 degrees. This process results in the creation of metallic iron, which is also known as sponge iron, direct reduction iron (DRI), metalized iron, or hot briquetted iron.
Features
1. The high porosity (25-30%) of our product results in excellent reducibility.
2. The uniform size and spherical shape of our product provides excellent bed permeability.
3. Acid pellets are designed to have a high strength of 150-200 kg or more.
4. The heat consumption is significantly lower than that of sintering.
5. Our product features a high iron content and a uniform chemical composition, resulting in lower flux and fuel requirements for the furnace.
6. Our product has a low FeO content.
7. Our product is easy to handle.
8. Product boasts excellent levels of carbon and FeO, with particularly low levels of FeO. This makes it a highly desirable choice for steel mills utilizing DRI to reduce carbon, as the low FeO content offers a significant advantage in the carbon reduction process. This feature, combined with our product’s exceptional quality and low impurity levels, translates to improved efficiency in steel production.
9. Our pellet production process does not involve the use of lime, which means there is no wearing of the inner lining.
10. Material handling results in minimal dust generation.
11. Product has excellent flowability, ensuring continuous and trouble-free charging in bins, pipes, and conveyors.

Ferro Alloys
Ferro alloy refers to various alloys of iron with a high proportion of one or more other elements such as manganese, aluminum, or silicon. They are used in the production of steels and alloys. The alloys impart distinctive qualities to steel and cast iron or serve important functions during production. Ferro alloys produced by us are used as raw materials for the manufacture of stainless steel products. We also sell specialised ferro alloys – low and medium carbon – for special steel applications. We sell ferroalloys of various grades, a finished product, to steel companies primarily in the states of Odisha, Jharkhand, Karnataka, Uttar Pradesh, Haryana and Rajasthan.
Pellets
Pellets are a type of agglomerated iron ore fines which has better tumbler index when compared with that of parent iron ore and can be used as a substitute of lump ore for the production of sponge iron and in blast furnaces for the production of hot metal. The iron pellets are produced with cold crushing strength (CCS) of 210+ and porosity of 24+” which helps to maintain grade in DRI fem – 80+ and our product mean particle size (MPS) is ~9.5-10 which assists in reducing oxygen in kiln and maintain consistency in grade. Iron Pellets are used as raw material for sponge iron and blast furnaces.
AIC can produce various grades/quality of pellets because of having a rotary kiln where the pellets are heated and fired uniformly. The process can use multiple ores simultaneously by applying the art of raw material blending. Pellet process helps save energy i.e. power because of excellent heat recuperation and lower drop in pressure of gases.

Billets
Adukia Industries is a leading manufacturer of advanced iron and steel products, committed to providing innovative solutions for the construction industry. As a prominent billet manufacturer, we play a crucial role in steel production, which forms the backbone of construction projects across the nation. Recognizing the importance of billet quality in determining the overall quality of steel, we ensure premium billet production through stringent testing at every stage of the process. We offer customised billets for both domestic and international markets, catering to the demands of customers in Chhattisgarh, Uttar Pradesh, Punjab, Rajasthan, Maharashtra, Nepal, and Bangladesh.
Billets are sections of metal used for rolling into bars, rods, and sections. They are typically cast into rectangular or cross-sectional shapes, making them compatible with secondary processing. Billets are produced through continuous casting, extrusion, or indirect heat treatment, followed by hot rolling of an ingot or bloom. They serve as raw materials for manufacturing TMT bars and structural products used in construction.
