The application discloses an online quenching steel quenching layer depth and residual stress control method, relates to the technical field of metal material heat treatment, and comprises the following steps: first, presetting initial process parameter sets; second, configuring detection and control devices; third, establishing a dynamic feedback closed loop; fifth, precisely controlling cooling water temperature; sixth, roller rolling cooperation; and seventh, slow cooling pit waste heat tempering. The method realizes precise quantification of process parameters, has extremely high quality stability, and through a large number of simulation and experimental research, the influence law of key process parameters (cooling water temperature, cooling water flow, quenching time and air cooling time) on final results (quenching layer depth and residual stress) is determined, which makes process design change from 'experience dependence' to'model guidance', realizes accurate control of the quenching layer depth and residual stress, and greatly improves the consistency and reliability of product quality.

The invention belongs to the technical field of fertilizer production equipment, and particularly discloses a system for fertilizer production and a use method thereof. The system comprises a fluidizing and spraying subsystem, a feeding subsystem, an external temperature control subsystem and an intelligent control and on-line monitoring subsystem, the core of the system is a fluidized bed with an expansion section, a barrel section and a conical bottom cylinder, and the fluidized bed adopts a multi-region gas distribution component, a layered spraying module and a partitioned temperature control design; according to the invention, the integrated design of other systems is combined, so that the integrated continuous production of the self-disintegration type functional fertilizer is realized, and the problems of process splitting, low efficiency and poor product consistency in the production of the fertilizer with a multi-layer structure are solved; the integrity of the gas production core of the self-disintegrating fertilizer particles, the uniformity and consistency of the thickness of each functional layer and the stability of the disintegration performance among batches are ensured, and the spanning from a laboratory formula to large-scale stable production is realized.
