The invention relates to the technical field of
alloy treatment, and discloses a low-temperature
forging and rolling process for a high-performance frog, which comprises the following specific steps: step 1, material heating: selecting high-strength
alloy steel as a
raw material of the frog, and heating the high-strength
alloy steel to 650-800 DEG C to ensure that the
plasticity and
toughness of the material are suitable for
forging; 2, preliminary
forging is conducted, specifically, the heated material is subjected to preliminary forging, the material is forged into the preliminary shape of the frog through a die forging technology, and the basic size and shape are ensured; by gradually reducing the gap between the rollers, the frog obtains higher precision and uniform deformation in the rolling process, and the method is beneficial to ensuring the consistency and
repeatability of each rolling stage, so that the consistency and quality of a final product are improved; by adopting the mode of gradually reducing the gap between the rollers, the
internal stress generated by the frog in the rolling process can be effectively reduced, the
mechanical property of a final product is optimized by uniformly applying pressure, and the possible
stress concentration problem is reduced.
