Wire rod for graphitization heat treatment and graphite steel

The present specification discloses a wire rod for graphitization heat treatment and a graphitic steel, whereby the graphitization heat treatment time is greatly reduced and fine grain graphite is uniformly distributed in a matrix during the graphitization heat treatment. According to one embodiment, the disclosed wire rod for graphitization heat treatment comprises, in weight percent: 0.65% to 0.85% of C; from 2.00% to 3.00% of Si; from 0.15% to 0.35% of Mn; from 0.005% to 0.1% of Ti; 0.01% or less of N; 0.0005% or less of B; 0.05% or less of P; 0.05% or less of S; and a remainder of Fe and unavoidable impurities, in which the values of the following formula (1) satisfy-1 to 1 (inclusive), and the microstructure may contain, in area fraction, 40% or less of ferrite, a total of 5% or less of bainite and martensite, and a remainder of pearlite. Formula (1): 100 * ([Mn]-0.25) 2-(100 * [N]) 2. In formula (1), [Mn] and [N] each refer to the weight% of the alloy element. 本说明书公开了用于石墨化热处理的线材以及石墨钢，由此石墨化热处理时间大幅减少，并且在石
