1. a kind of complex phase forges abrasion-proof backing block preparation method, it is characterised in that comprise the following steps:

  • (1) raw material is selectedSelect low-alloy steel as raw material, essential element mass percent is as follows in low-alloy steel:

    C <

    0.8%, Mn 0.5%-14%th, Cr <

    2%, Si <

    2%, Cu <

    0.8%, Ai <

    2%, Mo <

    1%, Ni <

    1%, P <

    0.03%, S <

    0.03%;

    (2) above-mentioned raw materials are smelted into steel ingot;

    Steel ingot hot forging is caused into liner plate, room temperature is cooled to;

    (3) liner plate is heated to after austenitic temperature, and MS points are cooled to soon, and slow cooling, to room temperature, finally carries out being tempered obtaining institute again againNeed the serial liner plate of complex phase forging.
