ESPON-HR Anti-Scale Protective Coating Liquid for Hot Rolling

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

ESPON-HR is a protective coating that significantly reduces scaling on billets and ingots during the process of heating prior to hot rolling and hot forging. Occasionally, in pusher- type furnaces when the billets are heated, they get stuck to each other at high temperatures. This is also seen during induction heating of billets for hot forging. It has been shown that the issue of billet sticking can be avoided by applying ESPON-HR just to the contact surfaces of two billets. ESPON-HR Anti-Scale Protective Coating can be applied by dipping, brushing, or spraying. Better surface finish for hot rolled or hot forged components is ensured when ESPON-HR Anti-Scale Protective Coating is used. The temperature or heating time of billets or ingots is unaffected by this coating. When hot rolling or hot forging is done, the coating is removed. ESPON-HR is non-flammable and non-hazardous.

Benefits of ESPON-HR Anti-Scale Protective Coating

1. Significantly less scaling on ingots and billets when they are heated for hot forging         

2. Ensures a higher yield

3. Assists in preventing forging rejection due to scaling-induced pit marks.

4. Stops billet welding or sticking when they are heated in furnaces or induction heaters

before hot rolling and hot forging.

5. Ensures better surface finish of hot forged or heat treated parts

6. Minimises unproductive and expensive work of scale disposal

7. Minimizes scale deposit damage to the floor and furnace hearth

8. Can be easily applied by brushing, spraying or dipping

9. Ingots or billets can be protected with ESPON-HR at temperatures as high as 1280 deg. C
