Compared with the prior art, the utility model has the advantages that: the device surface is equipped with the metal powder composite coating who contains titanium, tungsten carbide, zirconia, has high temperature resistant, wear resistance, and simple structure, practicality are strong, the effectual life who prolongs the tapping machine drill bit guarantees that the tapping is smooth and easy.
Description
Technical field
The utility model relates to technical field of blast furnace ironmaking, and particularly a kind of blast furnace is used the taphole drilling machine drill bit.
Background technology
In the blast furnace ironmaking process of metallurgy industry, tap hole of blast furnace is one of main casthouse equipment, and the taphole drilling machine drill bit is the expendable part during ironmaking is produced; Because in use its contacts high temperature sludge iron; Being easy to scaling loss distortion even thawing can't re-use, and causes the life-span of taphole drilling machine drill bit all very short, goes out an iron usually and will change one; Go out an iron firmly and need two to three drill bits if run into the iron mouth, increased the cost of production process.
Therefore, tap hole of blast furnace needs a kind of have high temperature resistant, anti abrasive drill bit and then reduction ironmaking cost.
Summary of the invention
The purpose of the utility model provides a kind of blast furnace and uses the taphole drilling machine drill bit, and this apparatus surface is provided with and contains titanium, wolfram varbide, zirconic metal-powder compound coating, has high temperature resistant, wear resisting property, and simple in structure, practical.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of blast furnace is used the taphole drilling machine drill bit, comprises frame of the bit, angle of throat, and described frame of the bit one end is provided with angle of throat, and the outside surface of frame of the bit and angle of throat is respectively equipped with the coating that is wrapped in frame of the bit and angle of throat.
Described coat-thickness scope is 0.1～0.2mm.
Described coating is for containing titanium, wolfram varbide, zirconic metal-powder compound coating.
Compared with prior art; The utility model has the advantages that: this apparatus surface is provided with and contains titanium, wolfram varbide, zirconic metal-powder compound coating, has high temperature resistant, wear resisting property, and simple in structure, practical; Effectively prolonged the work-ing life of taphole drilling machine drill bit, it is smooth and easy to guarantee to tap a blast furnace.
Description of drawings
Fig. 1 is the systematic schematic diagram of the utility model.
Among the figure: 1-frame of the bit 2-angle of throat 3-coating
Embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
See Fig. 1; A kind of blast furnace is used the taphole drilling machine drill bit; Comprise frame of the bit 1, angle of throat 2, frame of the bit 1 one ends are provided with angle of throat 2, and the outside surface of frame of the bit 1 and angle of throat 2 is respectively equipped with the coating 3 that is wrapped in frame of the bit 1 and angle of throat 2; Coating 3 thickness ranges are 0.1～0.2mm, and coating 3 is for containing titanium, wolfram varbide, zirconic metal-powder compound coating.
This installs through field practice, through this apparatus surface after using scum is arranged, and red by burning, and after surperficial scum was removed, naturally cooling can also continue to use, and has effectively prolonged the work-ing life of taphole drilling machine drill bit, and it is smooth and easy, safe and reliable to guarantee to tap a blast furnace.
