The invention relates to a method for producing a wear-resisting steel plate. Steel comprises the following
chemical ingredients in percentage by
mass: 0.15 to 0.20 percent of C, 0.4 to 0.7 percent of Si, 0.7 to 1.50 percent of Mn, less than or equal to 0.020 percent of P, less than or equal to 0.010 percent of S, 0.020 to 0.10 percent of Ti, 0.0005 to 0.0020 percent of B, 0.010 to 0.020 percent of Nb and the balance of Fe and inevitable impurities. A production process for the steel comprises the following steps of: desulfurizing by molten iron,
smelting by a converter, refining,
casting continuously, rolling and performing
quenching-carbon partition (Q-P) treatment. In the ingredients of the wear-resisting steel, a C-Si-Mn-Nb-Ti ingredient
system and the Nb and Ti micro
alloy treatment are adopted, the
hardenability of the steel is improved by adding B, an appropriate heat treatment process is adopted to ensure that the steel plate has high
plasticity and
toughness, and the
impact energy of the steel plate is improved by over one time; and the heat treatment is performed by a Q-P process,
lath martensite and
lath retained
austenite (between 5 and 10 percent) are formed and 50 to100 nanometers of
carbide complex tissue is precipitated, so that the tissue is fine and uniform, and the tenacity of the steel plate is high.
