A Guide To Thermal Spray Coatings for Process Rolls
From Bender, a world leader in
reconditioning and coating high-wear industrial components, comes a line of
thermal spray coatings engineered specifically to meet the challenges
of process rolls in CGL, CAL and cold
mill environments. Because each
process
in the production of high-grade sheet
steel presents its own set of
parameters and problems (thermal shock, corrosion, ZN dross, abrasion,
slippage, tension), Bender has a
patented coating for each environment,
purpose-built to preserve process rolls and to keep
your line running longer
and more profitably than you ever thought possible. Bender's 50+ years of
experience yields a phenomenal success rate that is unequalled in the
marketplace. And, Bender's ongoing commitment to service, quick response
time, and top-notch technical support are a few more examples of Bender's
"value added" customer service approach. Your Bender representative has all
the facts about Bender's coatings for the steel industry. Call for a
technical analysis or quote. Get peak performance from your process rolls
with Bender coatings.
COATINGS FOR ROLLS IN A CGL
On a typical continuous galvanizing line, Zn dross undermines the
surface of pot rolls, and transfers to the sheet, causing defects that
render it unacceptable for stricter automotive requirements. Bender's HS
1101 coating is an effective way to protect pot rolls and
boost sheet quality to meet the toughest specifications. Specially blended
and sized with WC/Co, HS 1101 is a proven performer with substantial
advantages: resistance to wetting and hot corrosion from molten zinc,
superior strength in molten zinc, and resistance to thermal shock and wear
inherent in a CGL. Bender's proprietary technology for sleeves and
bearings is yet another weapon in Bender's arsenal against downtime. Get an
edge on your competition. Lower your production costs and boost your output
with Bender coatings.
COATINGS FOR HEARTH ROLLS
Because hearth rolls in continuous galvanizing lines and continuous
annealing lines contact steel strips moving under tension at very high
speeds and temperatures, they need special protection from three of Bender’s
proprietary coatings. Bender’s
PS 1037, PS 1110 and PS 1250 are specifically designed to protect hearth
rolls from wear, thermal shock, and metal buildup and to reduce slippage
caused by poor roll surface integrity.
In the heating section, Bender’s multi-layered ceramic coating, PS
1037 guards against iron and oxide adhesion, so there’s less maintenance and
less scrap. In cooling section,
our PS 1110 adds tractability to the roll surface, allowing you to increase
both line speed and output. In
the quench section, Bender’s PS 1250 fights thermal fatigue so rolls last
longer and perform better.
COATINGS FOR ROLLS IN AN ALUMINIZING LINE
In an aluminizing Line, a corrosive, high temperature environment can damage
pot rolls, shorten their service life and cause substandard strip quality.
High replacement costs, downtime and soaring product rejection rates
can result. Bender’s advanced,
multi-layer ceramic coating, PS 1250, is the solution!
Layers with graduating expansion rates serve to reduce thermal shock
and cracking. Ideal for sink
rolls, bridle rolls, top rolls, and pot furnace snouts.
Bender’s PS1250 coating offers: superior roll surface quality, wear
resistance, reduced dross buildup, higher strip quality, and easier narrow
to wide transitions. With
today’s more stringent automotive requirements, Bender’s patented PS 1250
ceramic coating is a giant step towards raising your bottom line.
COATING FOR PROCESS ROLLS IN A COLD MILL
Designed to meet the challenges of both wet and dry bridle applications in a cold mill, Bender’s proprietary hypersonically-sprayed coatings, HS 1150-B and HS 1101-B, will greatly enhance the performance of your process rolls. Due to their extremely high bond strength (to 12,000 psi) and hardness to 70 Rockwell C (twice the hardness of uncoated rolls), Bender’s coatings create a durable barrier against abrasion and corrosion proven to extend roll life far beyond that of uncoated rolls. There is a savings in downtime, lower maintenance costs, and the added benefits of reduced slippage, edge wave and higher overall strip quality. Turn your process rolls into star performers with Bender coatings.
