 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.
