[Ferro-alloys.com] According to the investigation of www.ferro-alloys.com, there is little technical difficulty in domestic cored wire business at present. Many different kinds of ferroalloys are used as raw materials in cored wire business, but related standards are not enough. There are some national standards, but parameters are usually adjusted in production progress, so few manufacturers abide by national standards. In wire delivering, there is no standard craft and many craft parameters are determined by operating workers. It is not accurate enough. As a result, good and bad enterprises are mixed up and adulteration is serious in cored wire industry.
