Embodiment 1
[0042] A production method of steel for bead wires provided in this embodiment includes steelmaking, continuous casting and steel rolling processes. The continuous casting slab section size produced by continuous casting is: 150mm×150mm, and the original wire rod size of the obtained product is
[0043] The specific production process is: top-bottom compound blown converter → LF ladle refining furnace → R8 m arc 6-machine 6-strand billet continuous casting machine → 150mm×150mm cross-section continuous casting billet → high-speed wire rod rolling mill controlled rolling → Stelmore wind Cold wire controlled cooling → Specifications of bead wire for hot-rolled wire rod.
[0044] The key control parameters are: (1) blast furnace molten iron + self-produced returned scrap steel, molten iron temperature 1320°C, molten iron composition content: P = 0.075wt%, S = 0.045wt%, Ti = 0.0032wt%; Carbon" operation, the end-point C content is 0.53wt%, the end-point temperature is 1583°C, ...
