Abstract
The invention relates to a method for repairing damage of the surface of a big clock pull rod of a blast furnace dual-clock furnace top. The method includes the following steps that (1) in the maintenance process of a blast furnace, a sealing device of the big clock pull rod of the blast furnace dual-clock furnace top is dismantled, and the damage portion of the big clock pull rod is exposed; (2) the damage portion is cleaned clearly through a hand-operated grinding machine and a polishing machine; (3) metal wear-resisting mending agents coat the damage portion, and a repairing mold is clamped at the damage portion; (4) residual metal wear-resisting mending agents squeezed from the edge of the repairing mold are scraped off through a blade; (5) according to use instructions of the metal wear-resisting mending agents, the repairing mold is dismantled later; (6) the polishing machine is used for polishing the damage portion of the big clock pull rod to be smooth; (8) the sealing device of the big clock pull rod is installed. The method is simple, short in time, and good in effect.
Description
Technical field
The present invention relates to a kind of method for repairing breakage on surface, be particularly suitable for the reparation of the two clock furnace roof large bell pull rod surface fractures of blast furnace.
Background technology
On the medium and small blast furnace of blast furnace process, commonly used two clock valve top charging system, the switch of great bell valve is by one group of large bell pull rod connection, drives operation by hydraulic jack.Great bell threshold switch frequency is higher, and the large bell pull rod great bell valve of at one end ining succession communicates with high furnace interior, and the other end hydraulic jack of ining succession is exposed in the atmosphere, so the large bell pull rod sealing must be tight, otherwise blast furnace internal high pressure coal gas will be discharged in the surrounding environment.In long use, the large bell pull rod surface can produce breakage because of operation friction, coal gas deflation.After the large bell pull rod breakage, its seal will frequent breakage, causes gas leak.This situation generally will be changed it in the past, required blast furnace to stop to produce but change large bell pull rod, and needed the time longer.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides the two clock furnace roof large bell pull rod method for repairing breakage on surface of a kind of blast furnace, its method is simple, and the time is short, and is effective.
The present invention solves the technical scheme that its technical problem takes: comprise the following steps: 1), when blast furnace maintenance, the sealing device of the large bell pull rod of the two clock furnace roofs of blast furnace is disassembled, the damaged position of large bell pull rod is exposed; 2), utilize hand-held abrasive machine, sanding machine that damaged position is cleaned out; 3), the abrasion resistance of metal healant is applied to damaged position, will repair mold cramping and repair the position; 4), will wipe off from the wear-resistant healant of excess metal that the repairing die edge is extruded with blade; 5), according to the operation instruction of abrasion resistance of metal healant, treat that will repair mould after the time pulls down; 6), polish smooth with the repairing position of disk sander with large bell pull rod; 7), the sealing device that installs large bell pull rod gets final product.
The inventive method is simple, and the time is short, and is effective.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is front view of the present invention;
Fig. 2 is vertical view of the present invention.
The specific embodiment
1), when blast furnace maintenance the present invention includes the following step:, the sealing device of the large bell pull rod 1 of the two clock furnace roofs of blast furnace is disassembled, large bell pull rod 1 damaged position 3 is exposed; 2), utilize hand-held abrasive machine, sanding machine that damaged position 3 is cleaned out; 3), the abrasion resistance of metal healant is applied to 3 places, damaged position, will repair mold cramping and repair 3 places, position; 4), will wipe off from the wear-resistant healant of excess metal that the repairing die edge is extruded with blade; 5), according to the operation instruction of abrasion resistance of metal healant, treat that will repair mould after the time pulls down; 6), polish smooth with the repairing position of disk sander with large bell pull rod 1; 7), the sealing device that installs large bell pull rod 1 gets final product.
Described repairing mould comprises left and right half module 2,4, and left and right half module 2,4 structures are identical, and it is identical with the external diameter of large bell pull rod 1 to be grinding that left and right half module 2,4 fastens endoporus that the back forms, and left and right half module 2,4 passes through bolting.
Claims (2)
1), when blast furnace maintenance 1. two clock furnace roof large bell pull rod method for repairing breakage on surface of a blast furnace is characterized in that:, the sealing device of the large bell pull rod (1) of the two clock furnace roofs of blast furnace is disassembled, the damaged position of large bell pull rod (1) (3) is exposed; 2), utilize hand-held abrasive machine, sanding machine that damaged position (3) are cleaned out; 3), the abrasion resistance of metal healant be applied to damaged position (3) locate, will repair mold cramping and locate repairing position (3); 4), will wipe off from the wear-resistant healant of excess metal that the repairing die edge is extruded with blade; 5), according to the operation instruction of abrasion resistance of metal healant, treat that will repair mould after the time pulls down; 6), polish smooth with the repairing position of disk sander with large bell pull rod (1); 7), the sealing device that installs large bell pull rod (1) gets final product.
2. two clock furnace roof large bell pull rod method for repairing breakage on surface of blast furnace according to claim 1, it is characterized in that: described repairing mould comprises left and right half module (2,4), left and right half module (2,4) structure is identical, the endoporus that forms after left and right half module (2,4) fastens is identical with the external diameter of large bell pull rod (1) to be grinding, and left and right half module (2,4) passes through bolting.
