High-strength steel grating plate and preparation method thereof
The invention relates to the field of grating plates, in particular to a high-strength steel grating plate and a preparation method thereof. The steel grating plate comprises, by mass, 0.2%-0.6% of carbon, 0.6%-0.9% of silicon, 0.3%-1.0% of manganese, smaller than or equal to 0.03% of phosphorus, smaller than or equal to 0.02% of sulfur, 4.0%-5.5% of chromium, 2.0%-3.0% of molybdenum, 0.3%-0.4% of vanadium, 0.2%-0.4% of zirconium, 0.1%-0.2% of rhenium and the balance iron. Manganese, chromium, molybdenum, vanadium, zirconium, rhenium and iron ore are smelted, carbon and silicon are added at the same time, and molten iron is prepared; the preparation method comprises the following steps: preparing flat steel and a cross bar through the processes of converter smelting, continuous casting, rolling and the like, assembling the flat steel and the cross bar in a welding manner to prepare the steel grating plate, and depositing a CrMoTiCoPdN coating on the surface of the steel grating plate by adopting a magnetron sputtering technology, so that the strength and the corrosion resistance of the steel grating plate are improved.
本发明涉及格栅板领域，具体为一种高强度钢制格栅板及其制备方法。所述钢制格栅板包括以下质量百分比成分：0.2～0.6％碳、0.6～0.9％硅、0.3～1.0％锰、磷≤0.03％、硫≤0.02％、4.0～5.5％铬、2.0～3.0％钼、0.3～0.4％钒、0.2～0.4％锆、0.1～0.2％铼、余量为铁。本发明通过将锰、铬、钼、钒、锆、铼和铁矿石进行熔炼，同时添加碳和硅，制得铁水；再通过转炉冶炼、连铸、轧制等工艺，制得扁钢和横杆，通过焊接方式进行组装，制得钢制格栅板，采用磁控溅射技术在其表面沉积CrMoTiCoPdN涂层，提高了钢制格栅板的强度和耐腐蚀性能。
