Suspended material and furnace temperature fluctuations. Blast furnace smelting process: blast furnace drill pipe furnace smelting is a continuous raw blast furnace drill pipe production process for reducing iron ore into pig iron. What is the overall working method for feeding into the blast furnace in batches and using the mining coal drill bit on the furnace throat material surface? Maintaining a constant height, coke and ore form an alternating layered structure in the furnace. h The use of blast furnace drilling rig should pay attention to maintenance, so that the product can be used for a long time. How to maintain the drill after use? When drilling steel parts, ensure adequate cooling capacity and use a metal cutting fluid. Good drill pipe stiffness and guideway clearance can improve drilling accuracy and bit life. Make sure the magnetic base and workpiece are flat and clean. When drilling holes in thin plates, the workpiece should be strengthened. When drilling large workpieces, ensure the stability of the workpiece. At the beginning and end of drilling, the feed should be reduced /. For materials that contain a large amount of fine powder during drilling, such as cast iron, copper, etc., compressed air can be used instead of coolant to help chip evacuation. Please clean up the iron chips wrapped around the drill body in time to ensure smooth chip removal. The use process of blast furnace drill bit is analyzed. Before drilling, inspect the drill bit for damage or loss. There are no hard objects such as cutting teeth, cemented carbide, and steel at the bottom of the well. The bottom of the well is clean and no metal is broken. Y adopts high air temperature and oxygen-enriched operation while injecting a large amount of coal. The drill pipe is made of high-strength steel and is suitable for blast furnace opening drill pipes for various blast furnace opening machines. In iron-making blast furnace production, blast furnace opening drill pipes are suitable for various refractory openings, mud opening drill pipes, etc. For more information, please check the direct adhering to the use of high-quality raw materials, high-quality alloys, and never falsifying the cost. The high-quality drill bits manufactured are provided to major steel mills, and the products and services; your word of mouth is my feedback, Adhering to the production: people-oriented. Playing the role of downward drilling, the drill bit is the main drilling equipment. According to the working environment and the geographical environment, the specifications and shapes of the drill bit should also be different. When carrying out oil drilling: well work, it should be based on specific needs. Based on the specific design scheme, select the drill bit reasonably and scientifically, and select the drill bit scientifically in the specific drilling work. The drill pipe between the adjacent two drill bodies of the blast furnace opening drill bit can be connected by a live wire. The blast furnace opening drill bit practically provides a fast opening speed, easy hole channel, easy tap hole depth and angle, and easy maintenance of tap hole mud bag for the blast furnace operation. qU cemented carbide mining ball teeth are also widely used as excavation tools. The structural design of coal drill bits for quarrying is reasonable and just right. Mining, tunnel excavation have been used in civil buildings. In addition, it is also used as a drill bit accessories for heavy-duty rock drills. The common reasons for bit loss and failure are: wear, and bit design. Reasonably related to the low opening efficiency of the drill bit and the inability to open the iron hole for a long time, which is related to improper operation and excessive opening time; unreasonable alloy teeth of the drill bit, under the erosion of high-temperature slag and iron sludge, blast furnace drill bit processing and manufacturing process, blast furnace drill bit wholesale , blast furnace opening drill bits, opening machine drill bits, blast furnace drill manufacturers have a complete range of products, excellent quality and favorable price. The top of the drill body is severely eroded, and the alloy blade falls off; the shoulder row effect of the drill bit is poor, and the high-temperature mud slag continuously erodes the drill bit during the opening process. , so that it is excessively worn; individual blades are not welded firmly in the groove, and teeth are lost during the drilling process. The main models of blast furnace opening drill bits are φ~φ blast furnace high temperature resistant drill bits, φ~φ mine drilling drill bits To mm, mm, mm, mm, mm, etc., it can also be customized according to drawings and samples to fully meet the needs of different customers.
