Blast furnace tap hole drill rod is suitable for various blast furnace tap hole machines. In the production
of iron making blast furnace, Blast furnace tap hole drill rod is suitable for various refractory openings,
gun mud openings, etc. The scope of application is wider, and it can also complete the chiseling of
various non-metallic materials (rocks, refractory materials, gun mud, etc.). The blast furnace tap hole
drill rod is made of alloy steel pipe, which greatly improves the fatigue resistance and shear strength.
Its main function is to transmit torque and transport drilling fluid, and the borehole is continuously
deepened by the gradual lengthening of the blast furnace drill pipe.
