Forging wherein the material is hammered consistent with the customers sizes & requirements, may be a process during which the ingot is heated within the furnace & then forged. The forging process help in cohesiveness and strength by elongation of the grain structure, which ends up in material having much higher load bearing capacities as compare to casted material. Thus these rolls being so superior in wear resistance to that of Cast Steel Rolls are specially adapted for roughing and intermediate plate mills and rod or bar mill rougher.

We strive to cope up with the increasing market demand of Forged Rolls and to take care of the specified standard. We manufacture the cast Rolls only as per M.S. rolls, forged en-8 rolls, forged en-9 rolls, forged en-31 rolls, forged en-42 rolls, etc. It comes along side Forging & machining consistent with the drawing specified.

Top SG Iron Rolls manufacturers

We are always looking forward to widening our business reach to attain precedent heights. Our continuous and dedicated efforts have finally brought laurels to the brand. We are a proud SG Iron Rolls manufacturer at the global level. The transparency and loyalty that we maintain with our clients make us the first choice in SG Iron Rolls manufacturer business.

Types of SG Iron Rolls

Pearlitic SG iron Rolls: Pearlitic Spheroidal Graphite Rolls have a thick layer of cast iron with nodular graphite, the name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic matrix, the softest grades have a pearlitic matrix containing ferrite around the graphite nodules, while the higher hardness grades have a complete pearlitic matrix, the carbide content increases proportionately with the hardness.

Acicular SG Iron Rolls: Acicular Spheroidal Graphite Rolls also have a thick layer of cast iron with nodular graphite, here, the name of such roll is based on the fact that the material consists of nodular graphite and carbides in a pearlitic – bainitic matrix, the carbide content is considerably higher in the harder grades than the softer ones.

Alloy Steel Adamite Rolls Manufacturers

Shree Gautam International is an outstanding brand in the competitive crowd of Alloy Steel Adamite Rolls manufacturers. We stand out in the trending market abiding by the principles of professionalism and customer satisfaction. We design and present you with a reliable and unique range of Alloy Steel Adamite Rolls. We have established our presence in the local as well as International market.

Alloy Cast Steel Rolls are obtained through a process of statically cast iron process. The rolls are classified as hypo-eutectoid steel rolls, which have been alloyed with Molybdenum and Chromium. The rolls are made to undergo heat treatment process involving double annealing. The process is followed tempering of the roll involving thermal shock resistance and toughness testing. The micro structure of Alloy Cast Steel Rolls is mainly pearlitic having broken cementite. The rolls are known for good weldability and offer high degree mechanical strength.

Shree Gautam International is in the race of top position with Alloy Steel Adamite Rolls manufacturers. The aura of the company has enabled us to take the overseas market.These Rolls are suitable for rolling medium and heavy sections. These rolls are also used for roughing stands of strip mill.

To improve the quality of the grey cast iron various alloying elements may be added to give the roll an increased hardness. These alloy iron rolls have only small quantities of nickel (Ni), chromium (Cr) and molybdenum (Mo) and they give slightly better wear and strength than the straight grey iron. The alloy iron roll with higher quantities of alloy additions is much harder and wears better though naturally it is more costly and must yield higher rolled tonnage. The presence of Ni promotes the formation of graphite but as it is in a very finely distributed form it leads to greater toughness and resistance to fire cracking. Cr increases the tendency to form combined carbon and restricts graphite formation so giving a much harder but more brittle iron. Mo and tungsten (W) promote the formation of combined carbon and in addition they add to high temperature strength. With a Cr alloy iron there is a tendency for collar breakage in section rolls due to the brittleness and in addition a good supply of water is necessary for cooling the rolls to avoid fire cracking. A typical analysis of the roll is C- 3 %, Si- 1%, Ni – 1 % (or Mo -0.5 %) and Cr – 1 %. A common brand of alloy iron roll is ‘Adamite’ iron. The hardness of rolls is a measure of the resistance to wear and it is usually expressed in degrees of Shore scleroscope hardness. We are a leading Alloy Steel Adamite Rolls from Malerkotla, India.

Chilled Rolls Manufacturers

We are one of the biggest and well-known Chilled Rolls manufacturers in India. We also produce a good range of other Chilled Rolls including ICCI Rolls, DPIC Rolls, Bainitic Chilled Rolls & Shafted Chilled Rolls. Customers appreciate our products for his or her quality features like dimensional accuracy, unmatched durability and excellent performance under tough conditions. We take time to research the necessity of each customer and also manufacture customized products when ordered in bulk.

The steel shafts are fitted within the Barrels with shrink fitting technology along side M.S lock nuts on each side of the barrels. This method annihilates the probabilities of loosening the shafts. We are concentrate on manufacturing chilled rolls barrels for TMT, FLAT BARS, ROUNDS, SQUARE MILLS, Etc. Whether mill is manual, automatic or semi-automatic.Proper chemical composition are going to be done consistent with the stand nos and material which need to be produce from our rolls. order and be tension free.
We are leading Chilled Rolls manufacturers & exporters in India.

A clear chilled roll features a surface layer of white iron produced by inducing rapid cooling at the surface (by means of a chill within the mould) which restricts the formation of free graphite. The core is of grey iron thanks to the slower rate of cooling and therefore the intermediate zone may be a mixture of white and gray iron. The necks and wobblers or spade ends aren’t to be chilled and hence retain greater toughness. The chilled layer is tough and wear resistant but it’s brittle. A product like Chilled Rolls requires accuracy and precision, and our expert team guarantees that. What makes us one among the most effective Chilled Rolls exporters is that the mutual affection with our clients.

Types of Chilled Rolls

1. ICCI Rolls: These are cast iron based rolls alloyed with Nickel, Chromium and Molybdenum having a matrix of pearlite and carbide with flake graphite. The material has very good thermal properties coupled with property of imparting good surface finish to the product.

2. DPIC Rolls: These Rolls are made of a high alloyed shell iron and a soft grey iron or ductile iron core metal depending on neck strength requirement. These rolls are cast both through centrifugal and static route.

3. Bainitic Chilled Rolls: Alloy elements of Ni、Mn、Cr、Mo etc., are added to bainitic nodular cast iron rolls for obtaining acicular (bainite-martensite) matrix in its micro structure of these rolls. These rolls can be produced by static casting and centrifugal casting.

4. Shafted Chilled Rolls: The steel shafts are fitted in the Barrels with shrink fitting technology along with M.S lock nuts on both sides of the barrels. This method annihilates the chances of loosening the shafts. We also Produce Chill Rolls Barrels by centrifugal casting, In this casting rolls remain free from pinholes and cracks.
