Acid Washing-free and drawing-free apparatus for steel strand

Abstract

The present invention relates to an acid washing-free and drawing-free apparatus for a steel strand, and belongs to the production equipment field of the steel strand. According to the apparatus, firstly oxide scale is online mechanically removed, wherein the power of a first drawing machine is adopted to remove the surface oxide scale of the 82B rod by a combination method of a bending treatment and a drawing treatment of a bending machine with the difference of hardness and ductility between the oxide scale and base iron; then a dust removing apparatus is adopted to remove the dust on the 82B rod surface; then the treated 82B rod is subjected to online phosphorization and saponification. With the present invention, a new production target of the steel strand production process without acid washing and drawing, and with online phosphorization and saponification is realized; the energy consumption is saved; the staff arrangement is reduced; the labor productivity is improved; the pollution is reduced; the environment is protected.
