Abstract

ARAME EM BRUTO DE AçO E MéTODO PARA PRODUZIR O MESMO. Expõe-se um arame em bruto e um método para produzir o mesmo. O arame em bruto é excelente na operabilidade da trefilação de arame, não suscetível a quebra do arame apesar de um aumento na velocidade de trefilação do arame, e redução de área, e capacidade de prolongar a vida útil da matriz pela supressão do calor da matriz. O arame em bruto é feito de aço que contém, c: 0,6 a 1,1%, Si: 0,1 a 2,0%, Mn: 0,1 a 1%, P: não mais do que 0,20%, N: não mais do que 0,20%, N: não mais do que 0,006%, Al: não mais do que 0,03%, e O: não mais do que 0,003%, sendo o equilíbrio formado por Fe, e impurezas inevitáveis. Além disso, o arame em bruto compreende uma estrutura de perlita em que uma relação de área de uma ferrita de segunda fase é não superior a 11,0%, e um espaçamento lamelar de perlita não inferior a 120 <109>m.GROSS STEEL WIRE AND METHOD TO PRODUCE THE SAME. A raw wire and a method for producing the same are exposed. Raw wire is excellent in wire drawing operability, not susceptible to wire breakage despite an increase in wire drawing speed and area reduction, and ability to extend die life by suppressing die heat . Crude wire is made of steel containing, c: 0.6 to 1.1%, Si: 0.1 to 2.0%, Mn: 0.1 to 1%, P: no more than 0, 20%, N: not more than 0.20%, N: not more than 0.006%, Al: not more than 0.03%, and O: not more than 0.003%, the balance being Fe , and unavoidable impurities. In addition, the raw wire comprises a perlite structure wherein an area ratio of a second phase ferrite is no greater than 11.0%, and a perlite lamellar spacing not less than 120 µm.
