Notes:
In this paper, using high tensile strength and yield strength of hot-rolling acid washingthin steel sheet instead of cold-rolling steel sheet as the vehicle frame is investigated. The high pureand finer grain steel can be obtained by deep deoxidation technology, deep desulfurizationtechnology, low nitrogen and microalloy-technology of Boron/Niobium/Titanium. High yieldstrength (σs〉340 MPa) and high specific elongation hot-rolling thin steel sheet have been producedin the EAF-CSP short flow product line. The mechanical property, shape, surface quality andtolerance of steel sheet after hot-rolling can be controlled by optimizing joining-casting-rolling andcontrolling-rolling-cooling technology. Based on the forming test, cold-bending test, welding testand fatigue test results, it can be seen that cold-bending property, forming ability and fatiguestrength of hot-rolling acid washing steel sheet is better and meet the product requirement of vehicleframe. This investigation can resolve the fracture problems of QUANSHUN vehicle, improve theworking life, provide reliable automobile and reduce the production cost
