Bottom Pouring Sets
Complete refractory sets for ingot casting: trumpets, centre blocks, runner bricks, nozzles and sleeves, made to your plate layout and mould sizes.
01
Cast the trumpet
Steel is teemed into the trumpet at the centre of the plate.
02
Split the flow
The centre block distributes the stream into the runner channels.

Fill from below
Runner bricks and nozzles feed each mould from the bottom, so the metal rises calmly and stays clean.
