Gaea Rock's Specialized Rock Drilling Tools for the Mining Industry
Gaea Rock is a leading innovator in the field of rock drilling tools, providing durable and efficient solutions for challenging environments. One specialized area where our products excel is in the harsh conditions of tapping holes in blast furnaces, where the working temperature generally exceeds 1000°C (1832°F). For these applications, our rock drilling bits are meticulously engineered with heat-resistant tool steel to meet the exacting requirements of the task.
Our alloy pillars in the drilling bits are designed to exhibit high toughness, exceptional hardness, and excellent red hardness, which is the ability to retain these properties at elevated temperatures. Such features significantly extend the service life of our reaming drill bits. Moreover, the lifespan of the drill bit body can reach 20 to 25 cycles, with the option to replace the alloy pillars multiple times, further enhancing the product's longevity.
Blast furnace tapping tools, produced by manufacturers like Gaea Rock, have distinct usage characteristics. The drill bits for dismantling furnaces feature cutting edges that are curved on both the leading and trailing faces, resulting in varying rake and relief angles along the main cutting edge. These conditions make for a challenging cutting environment, with uneven distribution of cutting speeds along the edge. Low-strength tips experience high-speed cutting, leading to severe wear.
Using blast furnace drill rods correctly involves several maintenance steps. It is essential to clean the hydraulic oil tank, replace the oil return, suction, pilot, and drain filters, and change the vent hole on the hydraulic oil tank cover. Fresh hydraulic oil should be added until the oil level reaches 200mm below the top of the tank. The vent screws on the hydraulic pump are then loosened, and once hydraulic oil flows out of both vents without any air bubbles, the screws are tightened. Starting the engine, one should observe the clean hydraulic oil flowing from the arm and boom cylinder pipes before repositioning them.
Furthermore, upon removing the plug on the bucket cylinder pipe and starting the engine, inspect the line for clean hydraulic flow before shutting down and reinstalling the bucket cylinder pipes. It is also crucial to disconnect the oil pipes and return lines to ensure proper hydraulic flow during operations.
Before inspecting the blast furnace drill bits for damages or missing teeth, it is imperative to confirm that the bottom of the well is free from cut teeth, hard alloys, steel pieces, and other debris to maintain cleanliness. Handle damaged metal and drill bits with care, removing them from steel mouths and placing them on rubber mats or wooden boards to prevent further damage.
In conclusion, Gaea Rock's rock drilling tools are engineered to withstand the extreme conditions encountered in mining operations, specifically designed to tackle the high-temperature environments of blast furnace tapping with enhanced durability and efficiency. Our commitment to quality ensures that our products continue to set the standard for mining tools in challenging applications.
