摘要:

A production plant containing three vacuum arc remelting (VAR) furnaces and one electroslag remelting (ESR) furnace is described. Production of about ten million pounds of a variety of material grades is analyzed by breakdown of the production program by steel grades and ingot size in order to evaluate the economies of the VAR and ESR processes. A realistic annual remelting capacity of the three VAR furnaces is about 11.5 million pounds for a mixed ingot production program with specific requirements of material quality and processing technology, taking into account the factors influencing the possible annual production. A graph illustrating the scattered values of melt rate and power consumption for steel remelted under varying conditions shows that the complexity of the ESR process can lead to very different statements when comparing the VAR and ESR processes. A correct comparison of the advantages and disadvantages of the two remelting processes and an understanding of the economic factors of each process requires a knowledge of the base on which the figures for comparison are determined.
