For developing a superior quality range of high alloy Centrifugal and Static Castings, we have incorporated advanced centrifugal technology in our production process. This centrifugal casting process is commonly known as ‘Liquid Forging’, which is used for producing cylindrical parts.

Characteristics of centrifugal casting process:

• Centrifugal casting is the casting process specifically adapted to the production of cylindrical parts

• Centrifugal casting pipes are made by pouring molten metal into a rotating mould

• The metal is solidified in cylindrical shape with high centrifugal force

• The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical situation with pipes

• The inside diameter has more impurities and inclusions, which can be machined away

• The process can also be adopted to produce various other products, using molds that can be permanent or expendable

• The rotational speeds are lower than those used in centrifugal casting. This process is used for making wheels, nozzles, valve bodies etc. This process is known as Semi-Centrifugal Casting
  
  

Benefits of the centrifugal casting process:

• Solidification happens at up to 120 times the gravitational acceleration, and consequently yields a highly compressed structure

• The process is gravity and pressure independent

• Mechanical properties substantially better as compared to static casting (can be compared with forged parts)

• The directional solidification of the casting, yielding a very uniform structure, free from inclusions and blow holes

• Not restricted to patterns (moulds, being permanent, mostly used from the extensive stock)

• No restriction on tube thickness and weight (dependent on mould size)

• No runners or risers are required for making of the product

• Our products are utilized in various high temperature and high corrosion wear applications. Typically the service temperature ranges between 400 to 1100 degrees centigrade. Our products are used as stressed components in many of these demanding environments.

• The alloys we cast are various High Alloy Grades like HF,HH,HK,HP,HU,HT 316,316L, Inconel 825, Inconel 625, Duplex 2205.

• Our typical low alloy grades for rolling, high wear and grinding applications are Grey Cast Iron, Adamite Steel, En 18, En19, En 24, KCP- 12, High chrome steel, Ni hard etc.

• Our Static Cast Work Rolls and Centrifugal Cast Work Roll Sleeves are used for hot rolling of various materials. The typical roll grades we cast are Adamite steel, High chrome steel, SG Iron, Chilled Iron, Gray Cast Iron.

• We also cast some of our own alloys, these grades have been developed for some our of clients specifically suited to their service conditions. We can assist our clients at every step for the right alloy selection of their product to get optimum results.

• We have successfully developed and introduced Low cost stainless steels like 410 grades for crushing, grinding, milling applications originally using chilled or cast iron materials.
