一、无酸洗工艺焊条芯丝在进行拉丝之前,首先必须去锈上油。过去我们传统的工艺是:校圆→剥壳(去氧化铁)→酸洗(去锈)→清洗→上浆→烘焙→拉丝此工艺主要目的是为了清除表面氧化皮及锈,同时涂上一层干燥均匀的润滑荆。在这工艺流程中,必须使用盐酸或硫酸,这不免会产生废酸,周围环境经常是酸雾迷漫,并且劳动强度也大。我厂自79年以来对无酸洗拉丝工艺进行初步尝试,通过一年来实践证明,无酸洗拉丝是可行的。无酸洗拉丝的荃本原理也是去锈上油。但不同的是:在拉丝过程中,采用机械设备去锈来代替酸洗去锈,固体润滑剂连续进行强制润滑,然后进入常规拉
First, the non-pickling process Wire rod in the drawing before, we must first rust to oil. The past, our traditional process is: school round → peel (to iron oxide) → pickling (rust) → cleaning → sizing → baking → drawing The main purpose of this process is to remove surface scale and rust, while the coating layer Dry and uniform lubrication Jing. In this process, you must use hydrochloric acid or sulfuric acid, which inevitably produce waste acid, the surrounding environment is often foggy, and labor-intensive. Since 1979, our factory has carried on the initial attempt to the non-pickling and drawing process. It has been proved through the past year that no pickling and drawing is feasible. No pickling brushed Tsuen this principle is to rust oil. But the difference is: in the drawing process, the use of machinery and equipment to replace rust pickling to rust, solid lubricant continuous forced lubrication, and then enter the conventional pull
