Smelting process of hot rolled steel strip

The invention relates to the technical field of hot-rolled steel strip production, in particular to a hot-rolled steel strip smelting process which comprises the following steps: S1, burdening; s2, distinguishing and mixing; s3, smelting and melting; s4, injection molding; s5, carrying out a tensile experiment; s6, carrying out stretching treatment; s7, edge cutting treatment is carried out; s8, grinding and polishing; s9, nitriding treatment; s10, coiling is carried out; s11, carrying out rust-proof packaging; and S12, warehousing is conducted, the width of the hot rolled steel strip forged in the step S4 ranges from 700 mm to 750 mm, and the thickness of the hot rolled steel strip ranges from 1.5 mm to 500 mm. Metal is smelted in a differentiated melting mode, low-melting-point metal is prevented from being overheated and vaporized, the batching proportion is kept, the manufacturing quality of the hot-rolled steel strip is guaranteed, impurities in a hot-rolled steel strip blank are removed through folding
