 Steel and Alloy Steel Castings
a) Stainless Steel Castings: A wide range of steels containing chromium and nickel, exhibiting high resistance to corrosion.
b) Tool Steel Castings: Any high-carbon or alloy steel used to make a cutting tool for machining metals and for metal casting dies.
c) Carbon Steel Castings: Steel that owes its properties chiefly to the presence of carbon, without substantial amounts of alloying elements (ordinary steel, straight carbon steel, plain carbon steel).
d) Girth Gears : The girth gear has been preferred over the gearless drives due to their lower initial cost, simplicity to install, operate and maintain. In the past few years girth gears have gone through enormous improvements.
They have high efficiency and the overall life of these gears depends upon proper lubrication and alignment. They are high quality, high precision component. The capital cost of girth gears is lower than others and they take less time to install. They are physically big and due to this they are unable to store for longer periods of time.
Girth gear materials have made several changes on their own. Casting is enhanced using full ring risering techniques. Simulation programs are installed for verification of proper solidification. New materials are used with an added advantage of increase in hardness and therefore increased ratings.
The girth gear is the heart of most mills and kiln drive system. They can't be used in spare parts inventory. They are also used in steel and sugar industry as well as paper and pulp industry.
e) Mill Headers: Mill headers finds heavy usage in industrial sectors as an essential part of various vehicles and machines.They are used in various industrial sectors including coal and mining, oil exploration, paper mining, chemical industries, cement plant industry, sugar mill and others. In industrial sectors these gears are used as an important part of conveyors, cranes, elevators, separators and kilns because they offer high power-density and modularity.
