| titleOfInvention | Preparation method of high-strength steel cable bolts |
| abstract | The invention discloses a method for preparing high-strength steel cable bolts. The processing steps include: a. casting rod material, in parts by weight, first putting 10-14 parts of scrap steel into an intermediate frequency electric furnace to melt into molten steel, and then adding carbon When the temperature in the intermediate frequency electric furnace rises to 1120-1220°C, add 30-35 parts of steel ingots, 30-35 parts of pig iron and 12-16 parts of recycled materials, and then discharge the slag. When it rises to 1450°C and comes out of the furnace, 0.4-0.6 parts of copper are added to the ladle together with the molten iron for pouring; the preparation method of the high-strength steel cable bolts of the present invention is processed by cold extrusion technology, which improves the strength of the bolts , reached the hardness value and strength value required by high-strength bolts of 12.9, solved the delayed fracture and fatigue fracture of bolts under high strength, reliable connection in use, not easy to break, improved the life of bolts, and met the requirements of various industries in the society The use of high-strength bolts requires. |
