Metal smelting furnace inner wall functional coating and preparation method thereof
The invention relates to a metal smelting furnace inner wall functional coating and a preparation method thereof, and belongs to the technical field of functional coating preparation. Comprising a double-layer structure formed by an outer ceramic coating and an inner metal connecting layer, the outer ceramic coating can isolate the diffusion effect between a smelting furnace and a metal melt in the smelting process, the inner metal connecting layer is used for enhancing the binding force between the ceramic coating and the inner wall of the metal smelting furnace, and therefore the service life of the coating is prolonged. The preparation process of the coating comprises the steps that after the inner wall of a metal smelting furnace is treated, the Cr20Ni80 alloy connecting layer is sprayed to the surface of the metal smelting furnace through a plasma spraying technology, and the ceramic coating is sprayed to the surface of the connecting layer. A plasma spraying process is adopted for preparation, automatic production can be achieved, the quality of smelted molten metal can be greatly improved, the reject ratio of products is reduced, the hardness and abrasion resistance of the inner surface of the metal smelting furnace can be improved through the ceramic coating, the material sticking phenomenon can be eliminated, and the service life of the smelting furnace can be prolonged.
本发明涉及一种金属熔炼炉内壁功能性涂层及其制备方法，属于功能性涂层制备技术领域。包括外层陶瓷涂层和内层的金属连接层构成双层结构，外层的陶瓷涂层可隔绝熔炼过程中熔炼炉与金属熔体之间的扩散作用，内层的金属连接层用于增强陶瓷涂层与金属熔炼炉内壁之间的结合力，从而延长涂层的使用寿命。涂层的制备过程包括：对金属熔炼炉内壁进行处理后，采用等离子喷涂工艺在金属熔炼炉的表面喷涂Cr20Ni80合金连接层，在连接层表面喷涂陶瓷涂层。本发明采用等离子喷涂的工艺制备，可自动化生产，可使熔炼的金属液品质得到极大改善，降低产品的不合格率，陶瓷涂层可提高金属熔炼炉内表面的硬度耐磨性，可消除粘料现象，提升熔炼炉的使用寿命。
