| Zusammenfassung: | The invention discloses an underground supporting rod manufacturing technique. The underground supporting rod manufacturing technique comprises the following steps that (1) a blank is calcined into a supporting rod through the hot forging technique; (2) carburizing treatment is conducted on the blank, a carburizing agent is delivered into a tempering furnace, and carburizing treatment is conducted for 15 minutes within the temperature range of 1200 DEG C; (3) the surface of the carburized supporting rod is coated with mineral grease anti-corrosion materials; and (4) the supporting rod is stressed at the constant temperature of 50 DEG C for one hour. The supporting rod manufactured through the technique has the advantage of being resistant to corrosion. |
