Production Process Of Lamination Rollers Fused With Increased Resistance To Degradation And Lamination Rollers Obtained By This Process. Comprising the steps of : (1) a charge melting furnace with residual liquid metal (a), alloy elements (a b) (a-c) and various scrap, melting to occur (2) load (P) at a temperature that may vary between l2000c and 1550 °c, depending on the constitution of the initial charge; later withdraws a sample of the load (P) to that to be done pre-chemical analysis (3) and, then, in function of the result of the pre-analysis (3) are made corrections (4) chemical composition; next is added (5) to the load (P) sulfur; later, draws a sample of the load (P) to be made new chemical analysis (6) enabling corrections for chemical composition (7); with the liquid metal (gm) ready chemically, this is hollow (8) to a pot of casting, where are also added (hr) rare earth; next, the mixture proceeds to casting (9), giving form to the shell from the semi-finished roll (II) |
