Description

Technical Field

[0001] The invention belongs to the field of blast furnace ironmaking and relates to a method for improving the service life of a disposable blasting cap. Background Art

[0002] Disposable blasting caps are easy to use, so Chongqing Iron and Steel blast furnaces use disposable blasting caps instead of permanent blasting caps. Disposable blasting caps are easy to replace and cheaper than permanent blasting caps. At the same time, they can increase safety when plugging the mouth.

[0003] The existing disposable blast cap is a consumable in the daily production of the blast furnace. A disposable blast cap needs to be replaced each time the iron mouth is blocked. If the disposable blast cap is burned out during blocking, mud will leak from the blast furnace blockage, resulting in insufficient mud removal and a shallower iron mouth depth, which will affect the safety of iron tapping. During the iron tapping process of the blast furnace, large flow will escape, iron removal time will be short, and slag iron cannot be completely discharged, affecting the smooth operation of the blast furnace. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a method for increasing the service life of a disposable blasting cap, which can prevent the front of the disposable blasting cap from contacting molten iron and effectively protect the blasting cap in a short time.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for improving the service life of a disposable blasting cap, comprising a disposable blasting cap body, the disposable blasting cap body comprising a disposable blasting cap slag iron contact surface arranged at one end, the method further comprising the following steps:

[0006] S1, heating the disposable gun cover body at high temperature;

[0007] S2, evenly apply the glass water on the contact surface of the disposable blasting slag iron, apply it 1-3 times, and form a glass water protective layer after cooling;

[0008] S3, installing the processed disposable gun cover body on the gun nozzle to fix it to prevent the disposable gun cover body from falling off;

[0009] S4. After the blasting is withdrawn, remove the disposable blasting cover body, use a crowbar to remove all the slag and iron on the surface of the disposable blasting cover body, re-apply windshield washer water, and then use it again.

[0010] Optionally, the heating method is placed on the slag trench cover, using the heat radiated by the high-temperature slag for heating, without the need for additional heat consumption for heating.

[0011] Optionally, the glass water is a high temperature resistant mixture, which is viscous and is shaped and attached to the contact surface of the disposable blasting slag iron after cooling.

[0012] The beneficial effects of the present invention are as follows: the present invention improves the safety during iron hole blocking, reduces the phenomenon of disposable blasting cap burning and missing, increases the service life of the disposable blasting cap, reduces the consumption of the disposable blasting cap, and reduces the ironmaking cost.

[0013] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS
