Magna liber Doesphonicas et Alloy Steel Dimittings sunt maxime de ferro ingot, quae dividitur in magna ingot et parvum in speciem ferro ingot. Plerumque Missam major 2T ~ 2.5T, diameter est maius 550mm ~ 550mm ingot vocavit magna ingot, alia est parva ingot.

Press forging ingot forging used before the temperature of the heating furnace when loading is divided into cold ingots (generally for room temperature) and hot ingot (generally greater than room temperature) for cold ingots at below 500 ℃ heating plastic is poorer, and formed by an ingot in crystallization process and residual stress and temperature stress direction, all kinds of tissue defects will cause stress concentration, if a misalignment heating specification, easy to cause Crack. Ergo in humilitate temperatus scaena frigus ingot calefacere, loading temperatus calefactio celeritate debet limitatur.
Forging heating large ingot with multi heating specifications, due to its large section size, in the center of the tensile stress is very large, coupled with low ingot strength, poor plasticity, so the forging temperature stress is easy to crack when heating, therefore, the furnace temperature can not be too high, heating speed should also be carried out slowly. Exempli gratia, quia ipsum structural ferro et stagnum structural ferro, in fornacem temperatus plerumque CCCL ℃ ~ DCCCL ℃, in ingot magnitudine parva, in fornacem temperatus est magna et in tormento. Steel enim steel, ut summus celeritas ferro, summus chromium ferro facile crack cum succenderetur, fornacem temperatus temperatus ad CD ℃ ~ DCL ℃. Cum temperatus est altior DCCCL ℃, ingot potest calefacta ad celeritatem citius, sed non ieiunium ne eventum remittings intus et extra temperies differentia est magna. Exempli gratia, Dolonos et ipsum structural Steel et Alloy structural Steel patitur temperatus differentia inter L ℃ et C ℃.
Cum calefactio parva ferro ingot, propter parvum sectionem magnitudine, in RELICTUM accentus et temperatus accentus per calefacit non magna, calefactio celeritate potest esse citius, ergo carbonis citius calefaciendum specificationem in tabs. For small high-alloy steel ingot, because of its low temperature thermal conductivity is poor, and large cold ingot heating, also use multi-stage heating specifications, forging blanks can be installed at 700℃ ~ 1000℃ temperature furnace.
Ut breviare calefactio et salvare cibus, magna ingot a ferro officina post nudos, directe ad colantum workshop fornacem calefacit, hoc genus ferro ingot vocatur calidum ingot. When hot ingot furnace charging, the surface temperature of 550 ℃ ~ 650 ℃, due to the hot ingot in good plastic state, temperature stress is small, so the furnace temperature can be improved, depending on the ingot size and material is different, can be in commonly 800 ℃ ~ 1000 ℃ furnace, small ingot furnace temperature can be unlimited, after charging can be one of the largest heating heating speed.
