摘　　要：为使φ5.5 mm C82DA胎圈钢丝用盘条的脱碳层深度不大于0.03 mm的比例由78%提高到85%以上,对影响盘条脱碳层深度的因素进行分析研究。提出控制措施:加热Ⅰ段温度由1 030～1 070℃设置为1 040～1 060℃,均热段温度由1 090～1 130℃设置为1 100～1 120℃,浮动范围都由40℃缩小为20℃;钢坯待轧时,加热Ⅰ段温度由1 040～1 060℃降低为1 010～1 030℃,均热段温度由1 100～1 120℃控制为1 050～1 070℃,控制空燃比不大于1.82,炉压控制在6～8 Pa。采取控制措施后,盘条脱碳层深度不大于0.03 mm的比例由原来的78%提高到89%,提升了盘条质量,更好地满足了用户要求。To increase diameter 5.5 mm C82DA wire rod for bead wire＇ s less than 0.03 mm decarburized layer from 78% to 85%, and make analysis and research on the reasons of effecting wire rod decarburized layer＇ s depth. To raise control measure ： the temperature of heating first stage sets from ! 030 - 1 070 ℃ to 1040 ~ 1 060 ℃, soaking zone＇ s temperature sets from 1 090 ~ 1 130 ℃ to 1 100 ~ 1 120 ℃, raging from 40 ℃ to 20 ℃ ; while roiling, the temperature of heating first stage sets from 1 040 - 1 060 ℃ to 1 010 - 1 030 ℃, soaking zone＇ s temperature sets from 1 100 - 1 120 ℃ to 1 050 - 1 070 ℃, air fuel ratio is less than 1.82, and furnace pressure is control under 6 - 8 Pa. After taking prevent measures, wire rod＇ s decarburized layer＇ s depth is no larger than 0.03 mm quality is increased from 78% to 89%. More wire rod quality, more satisfied customers.
