The invention discloses a cleaning and sweeping vehicle shell plate and a preparation method thereof. The cleaning and sweeping vehicle shell plate comprises a carbon steel layer and a corrosion-resistant steel layer which are connected through metallurgical compounding. The method comprises the following steps: laying a carbon steel billet between two corrosion-resistant steel billets to obtain a composite steel billet; subjecting the composite steel billet to vacuum welding and edge sealing to obtain a composite corrosion-resisting steel billet; heating and rolling the composite corrosion-resisting steel billet to obtain a composite corrosion-resisting steel coil; and subjecting the composite corrosion-resisting steel coil to straightening, acid pickling passivation or polishing to obtain the washing and sweeping vehicle shell plate. The cleaning and sweeping vehicle shell plate has high strength and high corrosion resistance, so that the low-cost cleaning and sweeping vehicle shell plate has higher durability under the condition of long-term service.

    本发明公开了一种洗扫车壳体板及其制备方法,所述洗扫车壳体板包括通过冶金复合相连接的碳钢层和耐蚀钢层。所述方法包括:将碳钢钢坯铺设于2块耐蚀钢坯之间,获得复合钢坯,获得复合钢坯;将所述复合钢坯进行真空焊接封边,获得复合耐蚀钢坯;将所述复合耐蚀钢坯加热轧制,获得复合耐蚀钢卷;将所述复合耐蚀钢卷进行校直、酸洗钝化或抛光,获得洗扫车壳体板。洗扫车壳体板兼具高强度与高耐蚀性,使得低成本洗扫车壳体板在长期服役情况下,具备更高的耐久性。
