Metal calcium bare wire and core-wrapped wire linked production process

The invention discloses a metal calcium bare wire and core-wrapped wire linked production process. The linked production process comprises the following steps that a calcium rod is processed, wherein the calcium rod is firstly machined through a lathe, the surface of the calcium rod is polished till the surface of the calcium rod is smooth, two ends of the calcium rod are grinded smooth, then the calcium rod is further processed to make the surface of the calcium rod free of cold laps and inclusions, whether the processed calcium rod is complete or is grinded non-successively is checked in the process, the successively processed calcium rod is saved and kept for usage, and the non-successively processed calcium rod is abandoned and stored in a waste product warehouse. Independent metal calcium bare wire extrusion and core-wrapped wire preparation in a traditional metal calcium core-wrapped wire production process are simplified into 'core-wrapped wire extrusion and core wrapping linked one-step production', a
