Problems solved by technology
[0003] At present, the material generally used for the guide tip of metallurgical rolling steel line is the overall wear-resistant and heat-resistant alloy steel. The problems brought about by this are: the material used for the blank is expensive, the overall cutting process is difficult, the process is complicated, and the yield is low. The use time of the product is still short and the replacement frequency is high; the material composition is complex and the recycling rate is low

Embodiment Construction
[0010] The processing technology of the guide point of rolling steel wire is characterized in that it comprises the following steps:
[0011] 1. Use ordinary alloy steel as the base material to make blanks; 2. When cutting the base, in order to ensure the shape and position tolerance of the workpiece, the area where the guide tip and the wire are in high frequency contact is cut, and spray welding or spraying resistance is required in the later stage. The cutting depth of the abrasive material area is 1.5-1.7mm, leaving the depth for spray welding or spraying wear-resistant materials;
[0012] 3. Use the method of induction remelting to heat the area that needs spray welding or surfacing welding to a suitable temperature, and use the prepared wear-resistant and heat-resistant materials to heat spray welding or surfacing welding on the surface of the workpiece to obtain high-quality wear-resistant, Heat-resistant working surface;
[0013] 4. Wire cutting is used to remove the ...

The invention relates to a processing technology of a steel rolling wire guide point, comprising the following steps of: firstly, making a blank by taking common alloy steel as base material; secondly, during machining on a base, cutting a region wherein the guide point is contacted with a wire frequently to guarantee form and position tolerance of a workpiece, cutting a region, which is required to be subjected to spray welding or be sprayed with wear-resistant material, with a depth of 1.5-1.7mm, and reserving depth dimension for spray welding or spraying of the wear-resistant material; thirdly, heating the region required to be subjected to spray welding or build up welding to an appropriate temperature by adopting an induction re-dissolution method, and carrying out hot spray welding or build up welding on the surface of the workpiece by blended wear-resistant and heat-resisting material to obtain a high-quality wear-resistant and heat-resisting material working surface; and fourthly, removing working allowance of the region subjected to spray welding or build up welding by adopting linear cutting, thus the workpiece meets a design dimensional requirement. According to the processing technology disclosed by the invention, common steel or alloy steel material with relatively lower price is taken as the base, cost of raw material is reduced, and the base material is easy to process; wear-resistant and heat-resisting performances of the working surface after being subjected to spray welding or spraying are high; rolling production efficiency is improved; and an easy-to-wear part of the workpiece can be subjected to surface induction re-dissolution again, and service life of a product is prolonged.
