Integrated forming processing for drill rods dedicated to blast furnace taphole opening, manufactured from premium alloy raw materials as base stock. Multiple heat treatment procedures are applied to improve the toughness of the rod body. With standard thread dimensions, the drill rods allow smooth assembly and disassembly without thread seizing. Capable of withstanding frequent impact during taphole drilling and resisting high-temperature burning at the furnace mouth, they fit small, medium and large ironmaking blast furnaces and are compatible with various taphole drill bits. Complete specifications are available, and custom processing can be arranged as required.
Special blast furnace drill rods for front-furnace operations are forged from alloy steel raw materials and undergo full-set heat treatment to improve overall material performance. Featuring precisely machined threads, they allow easy assembly and disassembly with minimal thread seizing. Resistant to vibration and high temperatures, these drill rods fit hydraulic tapping machines of various brands, catering to iron tapping demands of small, medium and large steel mills. Available in complete specifications, they are supplied directly from the factory for bulk orders.
