Sheet Steel Cold Reduction Mill Steel Coil Cold Reducing Mill
Our cold reduction mills can manufacture strip quality material
with thickness tolerances to plus or minus 0.005mm on carbon steel,
stainless steel and aluminum in commercially available tempers and
finishes.
We make cold reducing mill considering production
requirements for whole process of breakdown, rundown and
finish rolling to ensure good quality and quantity of finished
thickness cold rolled coils.
Different customers from different countries and regions require
different configuration and process cold rolling reduction mills to
cater their local steel sheet market, the rolling capacity (
rolling force, rolling speed, power consumption, etc.) differ with
the market change, so each cold rolling mill should be
designed accordingly.
Carbon steel sheets are most common metal sheet, most of carbon
steel sheets are low carbon steel (mild steel), medium and high
carbon steel sheets are high quality high tensile steel, we make
carbon steel sheet cold rolling machines tailored to corresponding
materials.
The cold rolling mills we mostly supply are carbon steel sheet cold
mills. With productivity improving and steel sheet demand increase,
the carbon steel cold mills are becoming higher speed, higher
precision, lower consumption and lower maintenance cost. Our
company always work with market, know well cold mill technology
development and customer anticipation.
We make each mill customized, after knowing customer requirements:
Typical reduction of hot rolled strip in cold rolling mill can
range from 50 % to 90 %. The reduction in each stand or pass is to
be distributed uniformly without falling much below the maximum
reduction for each pass. Normally the lowest percentage reduction
is taken in the last pass to permit better control of flatness,
gauge and surface finish.
As per customer requirements, budget and preference, we specify the
detailed specification of proper cold mill, 4high or 6high, tandem
or reversible, and suggest customer machine configuration level and
spares preparation. Customer is a part of our design, he will see
his cold mill is what he hopes.
