3000° F Polycrystalline Alumina Fibers

Forging…. Foward

2

Ceramic fibers are Silica based and….

Start shrinking at temperatures below 2000°F, continue to shrink losing their

thermal insulation properties through a of function of time & temperature

Provide inconsistant Thermal Performance of the furnace impacting heating

Uniformity of forgings, their meteligical Quality and potentially higher scaling

.

Unfortunately create costly Down time & Production losses, increased

Maintenance cost, Energy loss and offten the need for structural repairs

3

Ceramic fiber linings….

Offten opperate at or above their continous service temperature limits

allowing for no additional temperature capicity when burners are at full capicity

Service temperature limits are offten reduced additionaly by fluxes and compounds used

in the ingot manufactring process, resulting in increased deieratation / melting of the lining

4

MAFTEC® ALUMINA FIBERS ARE 3000°F MULLITE BASED….

Provides very low shrinkage rates of 1% @ 2600°and 1.5% @ 2912° F a melting

temperature above 3370° F allowing MAFTEC to maintain its thermal insulating properties

throughout the function of time & temperature, providing a long service life lining

Provide consistant thermal performance of the furnace lining positivly impacting

heating uniformity of forgings, their meteligical quality and potentially lower scaling

5

MAFTEC® ALUMINA FIBERS ARE MULLITE BASED….

Have no free silica; it’s contained within the mullite alumina structure, providing improved Safety benefits

through its raw material base and Controlled Fiber Diameter through the manufacturing process

Can provide these Operating cost improvements & benefits…..

Safer lining

Improved heating uniformity of forging

Reduced scaling on product

Improved lining thermal effectiveness – increased capacity

Improve combustion system control

Substantial reduction in downtime for lining repair & replacement cost

Increase lining service life

Reduction in annual fuel & emissions cost

6

MAFTEC® ALUMINA FIBER LININGS…..

Required no frequent outages for lining repair/replacement…..

Favorably impacting downtime cost & productivity

MAFTEC after 5 years in service…. MAFTEC after 10 years in service….

No signs of shrinkage, thermal shock, velocity or chemical damage…No repairs required.

Are not severely impacted by 2400°F -2600°F operating temperature…

contributing to improved furnace reliability- productivity and cost to operate

MAFTEC® Lintel

Previous Dense castable lasted 6 months, caused damage to the door lining

and provided a poor sealing surface for the door

MAFTEC® Lintel in service for over 17 months, no repair or downtime

Customer reduce energy cost by 13% annually, eliminated maintenance downtime to

repair and replace the lintel, increasing capacity and reduced operating cost

8

MAFTEC® Flue

Previous Dense castable after 6 months service life

MAFTEC® flue after 1 year in service performing very well

MAFTEC’s high temperature capabilities and fiber resiliency

have created another long term cost savings solution.

MAFTEC® & StelBolt® system…

The system is a easy as packing shrunken area in the furnace lining and StelBolting MAFTEC to the existing lining

MAFTEC® & StelBolt® Veneering System

Existing Lining Pack shrinkage joints Pin 1” layer of MAFTEC®

2nd layer of MAFTEC Auger style StelBolt® Installed until snug Over 1st layer joint Hi-Alumina retaining washer Installation complete

Instead of continously re-pack & replacing ceramic fiber linings, overlay them

with MAFTEC to protect the exsisting lining from high temperature and chemical attack

MAFTEC & StelBolt system has been installed Shrinkage gap now has a

protective barrier to eliminate shrinkage, hot spots and most importantly… Downtime

10

MAFTEC® & StelBolt® system Thermal performance….

Burner flame impact was causing the ceramic fiber lining to need repacking every 2 to 3 weeks & replacement 4 times

a year. The MAFTEC & StelBolt system was installed. No repair replacement or downtime after 16 months

Before & After Thermal imaging below shows the Thermal performance of the MAFTEC & StelBolt system, providing temperature& heating uniformity to the product

Before After

Have a new ceramic fiber lining…let MAFTEC protect it from the start!
