Description
技术领域technical field
本发明涉及金属表面工程技术领域,特别涉及一种组合式强化分料器翻板及其制备方法。The invention relates to the technical field of metal surface engineering, in particular to a combined reinforced material distributor flap and a preparation method thereof.
背景技术Background technique
在钢铁公司的炼铁配料系统中,三通分料器作为一个重要环节,需要向不同的两个方向皮带完成定量的送料任务,所以物料对其翻板的正反面都有很强的冲击,这会使翻板磨损相当地严重,经常需要补焊修复。补焊既浪费时间,又给生产带来诸多不便,导致生产效率严重下降。In the ironmaking batching system of the steel company, the three-way distributor is an important link, and it needs to complete the quantitative feeding task in two different directions, so the material has a strong impact on the front and back of the flap. This wears down the flaps considerably, often requiring repair welding. Repair welding not only wastes time, but also brings a lot of inconvenience to production, resulting in a serious decline in production efficiency.
传统的耐冲击磨损翻板主要由衬板基体、堆焊合金层及连接结构组成。在实际使用中,由于工况恶劣及堆焊金相组织粗大等原因,采用堆焊合金的衬板经常出现合金堆焊层脱落,导致翻板严重磨损甚至被击穿,直接影响生产的顺利进行。The traditional impact-resistant and wear-resistant flap is mainly composed of a liner substrate, a surfacing alloy layer and a connecting structure. In actual use, due to poor working conditions and coarse surfacing metallographic structure, the alloy surfacing layer often falls off on the lining plate using surfacing alloy, resulting in serious wear or even breakdown of the flap, which directly affects the smooth progress of production .
因此,如何提高三通分料器翻版的耐冲击、耐磨损性能,进而提高其使用寿命,成为关系炼铁物料分配和传输,以及生产运行连续性和可靠性的关键问题之一。Therefore, how to improve the impact resistance and wear resistance of the three-way distributor, and then improve its service life, has become one of the key issues related to the distribution and transmission of ironmaking materials, as well as the continuity and reliability of production operation.
