• Melting
The melting is carried out in the oxygen steel plant; the ladle capacity allows a continuous bottom pouring process the speed of which is permanently controlled. The metal analysis is checked by using a computer linked spectrograph.
• Heat treatment
- Heating to a temperature above AR3, austenitising at about 915°C and controlled cooling in furnace
- Intermediate holding at 600°C - 630°C and completion of cooling in furnace down to 300°C
• Fettling and dressing
The inner surface is processed fit-for-purpose so that the surface discontinuities - which might cause some sticking of the slag - are extensively removed. Additionally, the castings are descaled by shotblasting and the outside is additionally coated for transportation.
