Title: The Making Of A Steel Casting


1
The Making Of A Steel Casting
2
Casting processes have made it easier for
engineers to utilize the potential of metallic
and non-metallic resources to the fullest.
Consequently, the freedom of innovation has also
opened up its doors, thereby allowing the
creation of life-changing machines out of natural
elements. But the overall casting process is not
as easy to be executed as its common across
industries today. Especially in the case of
steel, casting operations need to be conducted in
a healthy and safe environment with a sharp eye
on preciseness at every step. A single
miscalculation can completely misbalance the
output quality while posing dangers to the life
of workmen. Here is a peek into the steps
followed by Investment Castings Manufacturers for
the inquisitive minded
3
Project Designing and Planning
Once the order has been received from the client,
it is necessary to note down the specifications
of the request. Out of the different types of
steels available, the one best suited to the
client's needs must be recorded. Next, the
feeding and filling system instruments must be
arranged. Appropriate patterns and core boxes,
sand molds, and sand cores needed for the process
can be identified after a careful study of the
specific casting manuals.

Gearing up Molding and Core Making Section
As a parallel initial preparation of steel
casting manufacturers in India, the molding and
the core making section demands the chiseling of
sand molds. They are made using two mechanisms
"green molding" (for limited-sized instruments)
and "chemical molding" (for life-sized
instruments), while their cores are designed in
the "Core Making" part of the section. Sand is
spread out on the casting patterns for
compressions to make molds and the final product
is filled with sand to determine its inner shape.
Once the desired core shape and mold size is
achieved, the instruments are bolted together for
casting.
5
Making Cast Products
Electric induction or fuel powered furnaces are
turned on a medium frequency for melting steel.
Depending upon the type of steel castings
required (alloys or carbon steel), the
temperature is set between 1450 Degrees Celsius
to 1650 Degrees Celsius. Once solid steel reaches
its molten state, designated addends like
chromiumand nickel are also put inside. In its
consistent liquid state, hot steel mixture is
poured into the sand molds.
6
Retrieving Cast from Molds
After a considerable time, steel solidifies in
the molds and become a definite piece. It is then
separated from the mold for further testing. This
process is usually carried out by the vibrating
shake-out system. To remove the fine sand
particles sticking on the cast surface, the goods
are put in a shot blasting system.
7
Processing Unrefined Cast Goods
Merely removing the sand is not enough to give a
finishing to the cast goods. For the same, they
have to be put through further processing
systems. During thesleeve-feeders cutting, the
feeding system channels are welded off from the
cast goods. While, through subsequent heat
treatment, it is put in high temperature for
restoring strength, hardness, and toughness
attributes. Finally, goods are deburred to remove
the fine pointy edges.
8
Final Laboratory Testing
To check the quality of goods being supplied
through the industry, Ferrous Castings India put
cast goods through laboratory inspections. Their
physical properties are evaluated and they are
machined to give them particular weight balance.
9
Ferrous Castings India perform a very responsible
task every day. Steel is a common metal used in
all of the public spheres, including industries
and household. Hence, the responsibility on steel
manufacturers become double fold as and when they
perform their business responsibilities.
