Workpiece alloy coating remelting control system and control method

Abstract

The invention relates to a control system and a control method for workpiece alloy coating remelting. The control system for the workpiece alloy coating remelting includes a single-chip microcomputer,and a high frequency furnace unit, a temperature acquisition unit and a stepping motor unit that are connected to the single-chip microcomputer. The single-chip microcomputer controls the high frequency furnace unit to heat a workpiece alloy coating; the temperature acquisition unit collects temperature of a workpiece surface layer in real time and send the temperature to the single-chip microcomputer; and the single-chip microcomputer compares the received temperature with a preset process temperature value, the stepping motor unit is controlled to move according to a comparison result, andthe stepping motor unit drives the workpiece to achieve rotation and horizontal movement through a workbench. Through the control system and the control method, automatic control of the workpiece remelting can be completed, the control precision is high, the yield of a workpiece is improved under the premise of saving human resources, and the problem of dependence on manual operation, and the likecan be solved.

Description

technical field [0001] The application belongs to the technical field of remelting, and in particular relates to a remelting control system and a control method of a workpiece alloy coating. Background technique [0002] In the production process of two-way sucker rod couplings in the oil field, thermal spraying of nickel-based self-fluxing alloy powder is required on the surface of the workpiece, and the alloy powder is remelted to ensure the corrosion resistance and durability of the workpiece in harsh working environments. Anti-wear properties. At present, there are many remelting methods, such as flame remelting, laser remelting, induction remelting and so on. The above remelting methods each have different advantages and are applied in different production processes. [0003] In the workpiece remelting process, the temperature control of the alloy coating on the surface of the workpiece is an important guarantee for the yield of the workpiece. In the actual productio...

Problems solved by technology

In the actual production process, most traditional factories rely on skilled workers to observe the melting process of the surface coating of the workpiece with human eyes to realize the remelting link. The production efficiency and yield are not high, the technical requirements for workers are high, the labor cost is high, and the workers physical health threat
