At the same time, they can move axially. Under the action of the torque and axial force of the drill bit, the soil is cut, destroyed and smashed under the action of the extrusion and centrifugal force of the working blade, forming a soil flow pressure of 9mm. When the soil flow moves to the place where there is no obstruction by the pit wall, the broken soil is thrown around the pit due to the centrifugal force, and the whole process of digging the pit is completed. The force balance design makes the furnace dismantler drill bit have good guidance, which is suitable for use with the downhole motor to be used in directional drilling and deep hole drilling. Reasonable arrangement of different positions makes the drill bit more aggressive and abrasive resistant. Y When overhauling the equipment, all switch handles should be locked when the power is cut off, and a sign "Someone is working, the drill is not allowed to send electricity", only the person who performs this work has the right to remove this card and send electricity. f Polished and raw steel pipes are made into drills after several processing steps. Through the processing of the steel pipe thickening process, the outer surface of the light pipe is bent inward, and the pipe wall of the steel pipe is thickened. The next step is threading and plating with copper for strength. However, non-destructive quality inspection is carried out, and the welding of steel pipe body joints is carried out. And: after that, the tube will undergo welding heat treatment and welding treatment to eliminate welding residual stress. Other tests on the finished steel pipe, including hardness testing, in-line drill pressure testing and non-destructive testing, are performed before the finished drill bits are painted and packaged. How does a blast furnace drill work? The wearing parts on the drill pipe include: shock absorber ring assembly, anti-strip rod tray, spring seat, and shock spring. Before use, Y Yushu must check the parts and lubrication conditions carefully, and use it only after it is considered to be in good condition. There are many kinds of Yr blast furnace bits. We can buy suitable products according to our production environment.

Wind break: General break wind is a semi-automatic operation, divided into reverse flow break wind and normal break wind. The main trend of the development of coal injection technology in blast furnace injection operation: the amount of coal injection is large, and the coke ratio is large. l Clean up the male or female button of the drill bit and apply thread oil. Article L: The ground roller should be filled with oil regularly, and the rotation should be kept flexible. A special product manufacturing enterprise integrating R&D, sales and service. Long-term professional sales of blast furnace drill bits, opening machine drill bits, and blast furnace drill manufacturers. When it is found that the rotation is not working or the wear is serious , The drill bit is the main tool for breaking the rock, and the wellbore is formed by the drill bit breaking the rock. How well a wellbore is formed, and the length of time it takes, depends on the ground drilled! The characteristics of the layer rock are not only related to the performance of the drill bit itself, but also to the degree of matching between the drill bit and the formation. Reasonable selection of drill bits plays an important role in increasing the drilling speed and reducing the overall cost of drilling. The solid raw materials such as coke and flux are fed into the blast furnace in batches from the furnace top charging according to the specified ratio, and the furnace throat-material surface is kept at a certain height, and coke and ore are alternately formed in the furnace. The layered structure, melted into iron and slag, gathers in the hearth, and periodically the blast furnace drill pipe is released from the iron mouth and the slag mouth. N Finance Department Jiaozuo City stud drill bit manufacturer and requires that the scale of each phase of solar-grade polysilicon projects is greater than ton/year, and the scale of semiconductor-grade polysilicon projects is greater than ton/year. The "Conditions" also make clear regulations on resource utilization and energy consumption, environmental protection, product quality, safety, hygiene and social responsibility, as well as supervision and management of the polysilicon industry. uWThen, dismantle the furnace drill bit to disassemble. Connect the drill box body to the turntable, slowly lift the drill rod|, so that the drill bit groove corresponds to the drill bit box core board-convex point, snap the drill bit into the drill bit box, take out the drill rod and the drill bit in turn. Article 1: To adjust the direction of the track, it must be directed by a person. Before pulling out the track, the end of the sleeper should be pulled out. When pulling out the curve! , should be the curve first! Straighten the two ends in a straight line, pull the curved line into the range of the curve, and make adjustments.

According to the different drilling pressure methods used in drilling, the drill pipe is divided into different types, friction pressure type drill pipe, machine lock pressure type drill pipe and combined pressure type drill pipe. Consumption h analyzed the on-site use conditions of the blast furnace drill bit, selected the ideal appearance design according to the use requirements, and determined a reasonable tooth and shape distribution process through experimental research, so that the drill bit has a good powder discharge effect under severe working conditions, and improves the performance of the drill. The overall service life of the drill bit. The S blast furnace drill includes a plurality of cutting edge portions arranged at the tip end of the drill, and a shaft-shaped drill body provided on the base end side of the cutting edge portion and having a shank portion formed on the base end portion. How does a blast furnace drill work? During digging, the drill bit rotates around the vertical axis and moves axially at the same time. The soil is cut under the action of the torque and axial force of the drill bit, and is damaged and smashed under the action of the extrusion and centrifugal force of the working blade, forming a soil flow that is pressed against the pit wall, and at the same time is lifted to the surface along the page. When the soil flow moves to the place where there is no pit wall block: due to centrifugal force: the crushed soil is thrown around the pit to complete the entire digging process. What is the working state of the blast furnace drill? The blast furnace drill is an indispensable accessory of the drill pipe. It is used to drill through holes or blind holes in solid materials, and can expand the existing holes. The commonly used blast furnace bits mainly include twist drills, coal blast furnace bits, diamond blast furnace bits, special blast furnace bits for water exploration, etc. Users can purchase them according to their own needs. There are many types of blast furnace bits. The commonly used types in mines are different types, types, and types. Drilling teams use larger and more useful ones. You can purchase blast furnace bits that are suitable for you according to your own production environment. Article 1: When transporting the rails, the lower end must be bundled firmly with a protective cover to prevent the rails from falling off or escaping during operation. c According to the form of injection pipeline: multi-pipe injection and single-pipe plus distributor injection. The drilling footage of the nX-only new drill bit mainly depends on the size and type of the drill bit, the hardness of the formation and the matching of drilling parameters, the quality of the drill bit, whether the drill bit type is suitable for the formation lithology, which is helpful for accelerating the drilling speed and progress. The footage of a single drill bit plays an important role, please choose a diamond drill bit according to the specific project. In the popularization and application of blast furnace bits, the abnormal scrapping forms of the drill bits are divided into: improper operation, and the drill bits are burned in the molten iron. The drill bit and the drill pipe are stuck and scrapped. The alloy teeth of the drill head are unreasonable. Under the erosion of high temperature sludge (> ℃), erosion grooves appear in the steel body of the head. The welding strength of individual alloy column teeth is low, and the alloy falls off during drilling. A large number of tests and product tracking have proved that the abnormal scrap form is the main form. The form of scrap should be paid attention to. It is necessary to improve the geometric structure, welding production process, and improve the drill bit. overall quality.
