Abstract
A tundish impact pad formed from refractory material, the impact pad (1) comprising a base (3) having an impact surface (5) which in use faces upwardly to receive molten metal poured onto the impact pad, and a wall (7) extending upwardly from the base around at least part of the periphery of the impact surface, the wall including an overhang (9) projecting over a peripheral region (11) of the impact surface (5), the overhang (9) including a plurality of protrusions (13) which project further over the impact surface (5) than the remainder of the overhang (5).
Claims18
A tundish impact pad formed from refractory material, the impact pad comprising a base having an impact surface which in use faces upwardly to receive molten metal poured onto the impact pad, and a wall extending upwardly from the base around at least part of the periphery of the impact surface, the wall including an overhang projecting over a peripheral region of the impact surface, the overhang including a plurality of protrusions which project further over the impact surface than the remainder of the overhang.
An impact pad according to any preceding claim, in which the distance by which the overhang extending between two said protrusions projects over the impact surface is substantially uniform along at least most of its length.
An impact pad according to any preceding claim, in which the overhang extending between two said protrusions is substantially straight along at least most of its length.
An impact pad according to any preceding claim, in which the maximum distance by which the or each protrusion projects over the impact surface is at least 110% of the maximum distance by which the remainder of the overhang projects over the impact surface.
An impact pad according to any preceding claim, in which the maximum distance by which the or each protrusion projects over the impact surface is no more than 600% of the maximum distance by which the remainder of the overhang projects over the impact surface.
An impact pad according to any preceding claim, in which the height of the overhang above the impact surface is non-uniform along its length.
An impact pad according to any preceding claim, in which the peripheral region of the impact surface comprises a trough extending around at least part of a central region of the impact surface.
A tundish containing an impact pad according to any preceding claim.
