Anti-Scale Protective Coatings

Billets and ingots of metal are heated to high temperatures before further processes like hot rolling and hot forging. Scaling/ oxidation and decarburisation occur on these billets and ingots during heating at high temperatures. Decarburisation occurring at high temperatures leaves the metal unfit for making critical components like rails, sensitive automotive parts like leaf-springs, etc., where decarburisation needs to be maintained as low as possible. Problems due to decarburisation and scaling are:

. Metal loss of 1.5% up to 5%
. Excessive decarburisation leading to rejections
. Scale pits leading to rejections
. Reduced forging die life due to impact of hard scale on die during closed die forging
. Mill skid during hot rolling
. Damage to hearth of furnaces and induction heater refractory and coils due to scales
. Scale disposal costs and efforts

After forming, the hot rolled, forged or cast components need to be heat-treated. During heat treatment, scaling causes problems of pit marks, poor surface finish, non-uniform heating, quench cracking and increased shot-blasting / acid pickling time due to heavy scaling.

Use of ESPON anti-scale protective coatings manufactured by Steel Plant Specialities LLP ensures that scaling and decarburisation are prevented or substantially reduced.

A range of ESPON protective coatings is available for different applications. The coatings are highly customised depending on the grade of steel, heating parameters and other process specifications.

ESPON-HF Anti Scale Protective Coating for billets and ingots during hot rolling and hot forging.

ESPON-HF protective coating controls decarburisation and reduces scaling on billets and ingots during heating prior to hot rolling and hot forging. ESPON-HF anti-scale protective coating can be applied by brushing, spraying or dipping. Use of ESPON-HF Anti Scale Protective Coating ensures better surface finish of hot rolled or hot forged components. This coating has no impact on heating time or temperature of billets or ingots. Coating gets removed during hot rolling or hot forging operations. ESPON-HF is non-flammable and non-hazardous.

 

Benefits of ESPON-HF Anti Scale Protective Coating:

  • Controls decarburisation to a minimum level.
  • Substantially reduces scaling during reheating billets and ingots for hot rolling/ hot forging.

  • Prevents quench cracking.

  • Prevents rejection of forgings due to scale pits.

  • Protects billets or ingots at high temperatures up to 1280 deg. C.

  • Reduces post heat treatment processes like shot blasting, grinding and acid pickling.

  • Ensures scale-free, superior surface finish of parts.

ESPON-HR Anti Scale Protective Coating for billets and ingots during hot rolling and hot forging.

ESPON-HR is a protective coating that substantially reduces scaling on billets and ingots during heating prior to hot rolling and hot forging. Sometimes, during heating of billets in pusher-type furnaces, they get stuck to each other at high temperatures. This is also observed during induction heating of billets for hot forging. Coating only the contact surfaces of  two billets with ESPON-HR has proven to prevent the problem of billet sticking. ESPON-HR anti-scale protective coating can be applied by brushing, spraying or dipping. Use of ESPON-HR Anti Scale Protective Coating ensures better surface finish of hot rolled or hot forged components. This coating has no impact on heating time or temperature of billets or ingots. Coating gets removed during hot rolling or hot forging operations. ESPON-HR is non-flammable and non-hazardous.


Benefits of ESPON-HR Anti Scale Protective Coating:

  • Protects billets or ingots at high temperatures up to 1280 deg. C. Approximately 50% to 72% reduction in scaling is possible during billet heating.

  • Prevents forging rejections due to scale pits.

  • Prevents billet sticking/ welding during heating of billets in induction heater.

  • Prevents damage to induction heater/ furnace hearth by substantially reducing scale that falls in IBH/ furnace.

  • Prevents scaling on forgings/ castings during heat treatment. Zero scaling during heat treatment achieved in many cases.

  • Enables salvaging of rejected forgings/ components where re-heating is required.
