The purpose of a blast furnace drill bit is to drill the taphole of a blast furnace.
A blast furnace drill bit is used to drill the taphole of a blast furnace. It is designed to one-shot open the taphole without replacement by connecting a small diameter bit with an identical rotation central point to the front end of a large diameter bit, thereby distributing the digging amount between the small and large diameter bits
A double bit for drilling the taphole of a blast furnace includes a blast furnace taphole opening large diameter bit, which is rotationally connected to a digging rod linked to a motor shaft, and a small diameter bit coaxially formed at the front end of the large diameter bit. The double bit is characterized by a hollow connection part at the rear end of the small diameter bit being removably connected to the cooling water injection port of the large diameter bit, positioning the discharge grooves on both bits on the same line
The performance of drill bits meets the requirements of blast furnace tasks, and improvements in bit design and soldering processes are made based on product tracking and analysis of failure forms
The drill bit is used in conjunction with a motor that provides power to drive all hydraulic functions of the drill and an air compressor that supplies the large volume flow of compressed air needed to remove drilling debris from the blast-hole
In summary, the blast furnace drill bit is an essential tool in the operation of a blast furnace, facilitating the opening of the taphole for the removal of molten iron or other materials. Its design and performance are crucial for the efficiency and safety of the blast furnace operation.
