The melt passes from the casting furnace without turbulences to the tundish of the casting machine and without contact to the atmosphere through the transition tubes into the mould. No oxides can form and get into the ingot.
With a three meter wide caster a total of 30 strands are cast simultaneously, each having a cross section of 75 x 54mm. The casting speed, depending on the alloy, ranges from 400 to 600mm per minute.
The flying saw cuts the continuously cast strands into ingots of the desired length, in the range of 650 - 750 mm.
The ingots are automatically marked with alloy and cast number and then stacked. The completed bundles are automatically strapped and can, at the customers option, be stretch foil wrapped and colour marked.
At the weighing table the weighing ticket is automatically applied and finally the bundle is moved to the storage conveyor where up to 32 bundles can be accumulated.
The most common HDC caster has a width of 3.000 mm.
The 3 m wide caster may produce up to 13 tonnes per hour T-bar or 8 t/h foundry ingot.
The largest HDC caster HE built to date is designed to cast 4 strands T-bar 850 x 300 mm or 24 strands ingot 106 x 106 mm simultaneously.
Continuous production is 17 t/h for T-Bar and 12 t/h for ingot.
