Something About Casting (Gating Design)

Continuous tapping usually refers to blast furnaces. A furnace is usually allowed to build up a well of iron and slag, this is tapped off at various times. On very large or cupola furnaces the iron and slag can be run off continuously. As to flat casting I'm not sure, but I've got a rough idea. I'll have a look for you.

Can you provide more? Maybe the entire paaragraph where they are used. Casting on flat may be as simple as continuous tapping into open top molds, which would leave the top open, or flat with no features on that surface.

Where is Milo? it is his area.

Hey wingman welcome back. If it is Steel and for mill production, not foundry work, they might actually mean continuous casting through a tundish into oscillating water cooled molds. This makes a solid shelled billet or bloom which is torch cut and then reheated and rolled into mill products my guess might be that casting on flat, again if for steel mill products, might actually mean thin strip casting.

TonyS has given reasonable answers as well, but if it steel for subsequent processing i' d bet on mine
