Recycling
steel scrap is a major part of the steel industry, but the industry doesn't stop
at just using recycling steel scrap; about 95% of water used in North America
for making steel is recycled. Recycling steel also saves the equivalent energy
to power about 18 million households for a year.

Standard Industrial Corp Model AS500-10 Shear
The Old Shear
The New Shear
Tell
Steel offers several different steel and aluminum cutting services ranging
from band saw to plasma cutting. Shearing sheet metal and thin plate has been a
service Tell Steel has offered for
years, and with cutting steel comes a lot of wear and tear on machinery. After
years of service one of the shears has now been replaced. The new shear is a
Standard Industrial Corp Model AS500-10 Shear. Its capabilities are abundant and
it will fit perfectly in with the demands at Tell Steel. It is a 100%
Made in the United States of America guillotine style shear.
While many competitors use a Swingbeam/Rocker
Arm, the power and precision of a straight line cut of the guillotine style
shear is far more advantageous. In a guillotine style shear the drive system
makes sure the upper blade comes down on the material in a straight line. This
is due to the linkage being driven directly above the metal being cut. In comparison, a Swingbar/Rocker Arm styled
shear has the blade come down in an arc or “swing” motion. The system pivots the blade from one side of
the end frames and brings the blade down in a swinging movement. In this process, the top blade moves in
relationship to the metal being cut while in a guillotine style it never moves
in relation to the metal.
There are some crucial factors in providing
the best cut possible and some of them include the hold down system and its capabilities
to hold the material in place, the angle of the upper blade to the steel as the
blade cuts it, and the strength of the drive system. The Model AS500-10 has all the crucial factors
for providing the best possible cut as well as many additional features. It is 80,000 PSI capacity rated, ensuring to
have enough power for all of the cuts needed by Tell Steel, Inc. It also has a strong sturdy frame and high tonnage
to hold down the steel being cut.
This shear comes equipped with many
features including an 8’ squaring arm, manual swing-away backstop, infinitely
variable power blade gap adjustment and a protractor for angle shearing. The following are some other interesting specs
of the shear:

Recycling Steel Cans
The United States uses over 100
million tin and steel cans in a single day. Strong magnets are then used to
collect the tin and steel cans from the rest of the trash. These magnets recover about 9,000
cans every minute.

Ocy-Acetylene
The Oxy-Acetylene welding and
cutting process is one of the oldest in the world. It requires acetylene gas to
be mixed with pure oxygen instead of air. This combination boosts the flame
temperature from about 2,000°C to about
3,500°C. It is sometimes called the “Gas Axe”.

A-36 Steel Bar, Plate and Shapes
ASTM
A-36 is a general purpose structural quality low carbon steel without advanced
alloying. It has
good forming, weldability and mechanical properties and easy to fabricate using
structural methods like mild cold and hot forming or welding. A-36 specifications for standard bars, shapes
and plates 8” or less in thickness maintain yield strength of 36,000 psi and an
ultimate tensile strength of 58,000 to 80,000 psi. Elongation in 2” is a
minimum of 23%. This material is easily welded using all welding processes.
Commonly produced in sheet, plate, bar, and structural shapes, its intended use
is riveted, bolted or welded construction like that of bridges and buildings
and for general structural purposes where aforementioned A-36 specifications
are required.
