is the starting of a crucible following a shut-down. In an NF furnace, starter\nblocks are required reaching up to 2\/3 of the coil height. These blocks are heat-\ned inductively and then settle together. At this point, small quantities of scrap\ncan be recharged. After reaching the 2\/3 filling level, larger quantities of scrap\ncan be added (5% of the total capacity) and melted. The furnace is brought up to\nthe maximum filling level at approx. 70% of nominal performance. The melt\nshould now be brought up to about 100 K below the normal tapping tempera-\nture, and maintained at this temperature for 1 hour. The furnace is then brought\nup to tapping temperature and the 1st tapping carried out.\n<\/p>\n","protected":false},"excerpt":{"rendered":"
