The utility model has the following contents:
in order to solve the technical problems, the utility model aims to provide a drill rod of a submerged arc furnace drilling machine for producing ferroalloy.
The utility model is implemented by the following technical scheme: the utility model provides a hot stove in ore deposit machine of opening a hole machine drilling rod for ferroalloy production, includes the drilling rod, the front end welding of drilling rod has three twisted steel, the gas guide hole has been seted up to the inside of drilling rod, the axial center line of gas guide hole and the axial center line collineation of drilling rod.
Preferably, the included angle of the connecting line between the circle center of each cross section of the three threaded steel bars and the circle center of the cross section of the drill rod is 120 degrees, so that the threaded steel bars at the front end of the drill rod can be uniformly stressed after the drill rod rotates, and the drill rod is prevented from being influenced by eccentric force.
Preferably, the tooth's socket has all been seted up to the front end of three twisted steel, and the tooth's socket can reduce the drilling rod and rotate the back, and the degree of difficulty of twisted steel drilling makes the drill bit that three twisted steel constitutes can get through the electric stove eye more easily.
Preferably, the front side and the rear side of the twisted steel bar are both provided with transverse ribs, the included angle range of the transverse ribs and the axial center line of the twisted steel bar is 45-70 degrees, and the directions of the transverse ribs on the front side and the rear side of the twisted steel bar are opposite.
Preferably, there are two welded places between the threaded steel bar and the drill rod, which are respectively the joint between the rear end of the threaded steel bar and the side surface of the drill rod and the joint between the front end of the drill rod and the side surface of the threaded steel bar, so that the threaded steel bar is more firmly connected with the drill rod, and the threaded steel bar is prevented from being separated from the drill rod due to too large stress after the drill rod rotates.
The utility model has the advantages that:
1. according to the drill rod of the submerged arc furnace tapping machine for producing the ferroalloy, compressed air generated by the air pump can enter the air guide hole through the rubber tube by the mutual matching among the drill rod, the threaded steel bar and the air guide hole until the compressed air is discharged from one end, close to the threaded steel bar, of the air guide hole, so that on one hand, a refractory material in a blocked furnace hole drilled by the drill rod can be blown out from the furnace hole; on the other hand forces the cooling to the twisted steel to prevent that the twisted steel from taking place to warp because of the high temperature, reached and avoided the drill bit card in the inside effect of stove eye, solved the drill bit and easily taken place to warp because of the high temperature in the front of the furnace, thereby caused the drill bit card in the inside problem of stove eye.
2. According to the drill rod of the submerged arc furnace tapping machine for producing the ferroalloy, the drill rod, the threaded steel bar, the air guide hole and the tooth grooves are matched with one another, and the side surface of the threaded steel bar is provided with the threads formed by the transverse ribs, so that the threads can drive the soil outlet hole during drilling, and the scraping effect on the hole-plugging refractory material is achieved; and three twisted steel mutual independence, even a certain twisted steel drops and also can not block up the furnace eye, has solved current drill bit card inside the furnace eye after, the drill bit easily breaks away from with the drilling rod to lead to the problem that the furnace eye is blockked up by the drill bit.
3. The utility model adopts the mode of connecting the drill rod and the threaded steel bar, only needs to weld the threaded steel bar again after being used and abraded, has convenient material taking, lower cost and easy popularization and use.
