Hot
Rolling
I first saw Stevenson &
Cheyne's rolling of hot metal, at their engineering works in
Bonnington, in February 1992.
The firm was working on orders for:
- 24 cones for a Glasgow ship yard for oil rigs.
- over 100 cylinders for BPCL.
The large oven used for these hot rollings was installed in
1981 and could operate at temperatures up to 1,200 degrees C.
For the hot rollings above it was operating at 900 degrees C
and was producing one hot rolling every 60 to 90 minutes. |
