Abstract

The invention provides a grinding rod production method based on a plasma cladding technology, and relates to the technical field of surface treatment. The grinding rod production method based on theplasma cladding technology comprises the steps that steel for manufacturing a grinding rod is subjected to design and surface pretreatment to obtain a round steel blank; and then a proper coating material is selected, process parameters of plasma cladding treatment equipment are set through a human-computer interface, and a layer of wear-resistant and corrosion-resistant material is sprayed on thesurface of the round steel blank to obtain the finished product grinding rod. Compared with a traditional process, the method is simple, the technological process of the plasma cladding technology can be automatically conducted through the plasma cladding abrasion-resistant treatment equipment, equipment operation is easy, labor intensity can be reduced, in addition, adopted iron-based alloy powder can obviously enhance the hardness of the grinding rod, the abrasion resistance and corrosion resistance of the grinding rod are improved, product quality is greatly improved, and finally, the round steel blank can be repeatedly utilized, so that the raw material cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a grinding rod production method based on plasma cladding technology. Background technique [0002] The rod mill is a mill in which the grinding body loaded in the cylinder is a steel rod. Rod mills are generally of the wet overflow type and can be used as primary open-circuit grinding. They are mainly used in cement, electric power, mining, coal grinding and other industries. At present, there are more than 20,000 rod mills of various types used in various mines in China, and the annual demand for rod mills of various materials and types is nearly 500,000 tons. In the international market for rod mills in related industries, nearly 5 million tons. [0003] The production process of grinding rods in most enterprises at home and abroad is as follows: designing round steel billets → heating in well-type electric furnace → straightening the press in a hot state → enterin...
