剑麻纤维芯浸油工艺流程

钢丝绳用黄麻、剑麻绳芯的原始浸油方式易产生质量缺陷:绳芯浸不透油,表面烤焦或浸油后通条含油率不均。根据生产实践,针对不同规格黄麻、剑麻绳芯实施改进措施,得出符合要求的工艺参数:φ3.2~16 mm的黄麻纤维芯单根浸入110 ℃连续生产线油锅中只需2.5~4.5 min即可达到纤维芯含油率26%~34%的要求,黄麻纤维绳芯只需连续生产线过油浸泡即可,无需成捆浸泡。剑麻纤维芯浸入110 ℃连续生产线油锅中过油3 min,收卷后在110 ℃油锅浸泡适当时间(1~2.5 h),然后烘干脱油30 min,即可达到要求。剑麻纤维芯浸油工艺流程:放线→在110 ℃连续线过油3 min→收入花轮→吊入在110 ℃的油锅浸泡1 h→吊出油锅后滴油30 min。黄麻和剑麻改进后的具体浸油参数见表1.
The original oil immersion method of jute and sisal rope core for steel wire rope is easy to produce quality defects: the rope core cannot be soaked in oil, and the oil content of the whole strip is uneven after the surface is scorched or soaked in oil. According to the production practice, the improvement measures are implemented for jute and sisal rope cores of different specifications, and the process parameters meeting the requirements are obtained: φ It only takes 2.5 ~ 4.5 minutes for a single jute fiber core of 3.2 ~ 16 mm to be immersed in the oil pan of 110 ℃ continuous production line to meet the requirements of 26% ~ 34% oil content of fiber core. Jute fiber rope core only needs to be immersed in oil of continuous production line without soaking in bundles. The sisal fiber core is immersed in the oil pan of 110 ℃ continuous production line for oil for 3 minutes. After winding, it is immersed in the oil pan at 110 ℃ for an appropriate time (1 ~ 2.5 h), and then dried and degreased for 30 minutes to meet the requirements. Oil soaking process of sisal fiber core: setting out → continuous line oiling at 110 ℃ for 3 min → collecting flower wheel → lifting into an oil pot at 110 ℃ for soaking for 1 h → dropping oil after lifting out of the oil pot for 30 min. The specific oil immersion parameters of jute and sisal after improvement are shown in Table 1
