ENGINEERING HAS BEEN GRANTED A NEW PATENT FOR IMPROVED USE OF SCRAP TIRES IN
MELT SHOP FURNACES *
Stebbing
Engineering has developed new technology that now allows scrap tires to replace
significantly greater amounts of electrical and chemical energy and charge
carbon in metal melting furnaces.
"With
today's ever increasing costs of energy and charge materials, this process will
have a very positive impact on steel production costs", says Leroy
Stebbing, P.E., the inventor of the process.
Our
original patent was for the use of tires
in a batch process method. This new
approach uses tires on an almost continuous basis. The tires can be whole tires
or parts of tires such as chopped, powdered, or granulated, etc. By feeding
tires in a controlled, continuous feed, we increase the use of scrap tires and
are therefore able to decrease the use of all other forms of conventional
energy such as electricity, natural gas and coal or coke.
In
most cases the mill is paid for disposing of the tires instead of having to
purchase coal or coke.
Scrap
tires contain significant amounts of high-quality steel scrap
Also,
scrap tires become the only source of charge carbon. The costs for coal or coke for charge carbon
is eliminated along with its transportation and storage costs. Scrap tires,
therefore, become part of the steel and are recycled much like scrap metal.
Tires
decrease and improve emissions from the furnace. They contain less carbon than coal so less
total Carbon dioxide is released. Also, tires increase the conversion of carbon
monoxide to carbon dioxide inside of the furnace. Therefore, greater energy is released inside
of the furnace where it is needed and CO emission outside of the furnace is
reduced. The energy available from CO released from the foamy slag process can
be converted to CO2 with the catalytic effect of tires.
The
new process also has major benefits for Consteel ©, and shaft furnaces where
the charge is fed on a continuous basis.
