Diffusion annealing of S690QL low alloy high strength steel plate, wear-resistant plate is to reduce the non-uniformity of chemical composition and structure of metal ingot, casting or forging billet, heating it to high temperature and holding for a long time to make the elements in the steel plate fully diffuse. Due to the long heating cycle and high temperature of diffusion annealing, although the composition of the steel is uniform, the structure of the steel plate is seriously overheated, and the grains grow violently, and the toughness and plasticity are poor. Diffusion annealing is widely used in ingots, casting and forging billets with high quality requirements due to its high energy consumption and serious burning loss.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, S690QL low alloy high strength steel plate high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of S690QL low alloy high strength steel plate wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
