Variety. And commonly used Άί—annealing (anneaHng), beating (qUenching), tempering (tempering) and so on. l π However, 'traditional steel belt heat treatment is to heat the steel strip to the Austenitizing temperature (about 820 ° C ~ 920 °)' quenching with water or oil straight ((11 ^ 11 ( ^ 丨 11 avoid) hardening, and then tempering to the required hardness, tensile strength or toughness. However, the traditional heat treatment method, direct quenching cooling only in a single step 'At this time the steel strip must face The volume change due to rapid cooling and the change in the elongation of crystals of loose iron in Asada due to the rapid change of the Vostian iron will result in such steel strips having too high residual stress, which is easy to deform and crack, and is resistant to impact Those with low strength, relatively brittle, short service life, and different thicknesses of steel, which can cause the hardness of the uneven surface to be inconsistent. Φ Therefore, the above-mentioned traditional heat treatment method of steel strip is not ideal, resulting in poor structural strength of the finished product. Increase the manufacturer's multi-level processing costs. The inventor borrowed many years of relevant research and field physical experience, and finally invented the "special-shaped steel belt heat treatment method" to obtain By conventional heat treatment.
