Description
Technical field
The present invention relates to a kind of slag scrapers, and in particular to a kind of slag scraper of converter oxygen lance belongs to slag scraper technical field.
Background technique
With development of iron and steel enterprises, yield is continuously improved, and the requirement for equipment operation increasingly improves；Oxygen rifle dry slag is one
It is straight there are the problem of, in process of production, when oxygen rifle dry slag, not only will cause the deterioration of oxygen rifle part radiating condition, be easy quilt
It burns out, but also will cause and propose rifle difficulty, be easily damaged nitrogen sealing；It also will cause oxygen rifle when serious and propose not plug for outlet, converter refining
Steel can not normally blow；Enterprise is influenced normally to produce；Existing 60t converter area is fitted without oxygen rifle and scrapes slag equipment, and rifle is mainly deposited
The problem of it is as follows:
1. oxygen rifle dry slag causes gun body locally to radiate, cause to burn rifle, oxygen rifle replacement frequency is high；
2. viscous rifle occurs for converter oxygen gun, the viscous steel slag of gun body is manually difficult to clean up, and is forced to move rifle in production process, when serious because
Steel bonding gun body can not mention nitrogen sealing of hole, it has to take burning torch measure；
3. being tempered when spray head and spray head are with upper bit steel bonding, causes oxygen rifle outer tube to burn leak, be forced to change rifle.
Summary of the invention
To solve the above problems, automatically controlling the invention proposes a kind of slag scraper of converter oxygen lance and realizing that oxygen robs surface extension
Slag cleaning, avoids artificial slag-removal belt from carrying out security risk, reduces the labor intensity of producers, improve labor efficiency.

Button, drive control mechanism give electrical executing agency's action signal, control solenoid valve obtain it is electric, pneumatic circuit conducting, executing agency opens
It is dynamic, embrace folder oxygen rifle；Oxygen rifle carries out mentioning rifle, drop rifle operation, can clean up the clinker being adhered to around oxygen rifle；End of operation is raw
Selection switch on control box is placed in remotely by production personnel by local；When master control room selects remote status, slag scraper is according to electrical
Control program is operated, and producers only need to observe field condition by long-range monitored picture, is completed, can be carried out when scraping slag
Next step production operation.
Further, the selection of local/remote switchs in the control box；When selection is local, it is arranged in operation interface
Remote Selection key signals are invalid, the Remote Selection key signals on remote operator interface and the Remote Selection switching signal in control box
For with operation, i.e., must two signals when being true, just can enter electric automatic control and scrape slag operation.
Further, its work of the slag scraper of converter oxygen lance is specific as follows:
The first step checks whether oxygen rifle hoisting mechanism and oxygen rifle wirerope are normal, it is necessary to assure oxygen rifle hoisting mechanism and oxygen rifle steel
Cord is in good working order；The monitoring of oxygen rifle tension and the alarm for accessing oxygen rifle monitoring modular are normal；
Second step, oxygen rifle pipette tips weld seam are answered smooth, and the body of a gun keeps smooth clean and tidy；Using Dreg Scraping Device of Oxygen Lance, its oxygen rifle must keep vertical
Directly, deviation is not greater than ± 50mm；
Third step establishes on the spot/teleoperation mode, sets local operation mode and remote operation mould for Dreg Scraping Device of Oxygen Lance
Formula；Teleoperation mode is converter master control room operation mode, and local operation mode is near production personnel on site's oxygen rifle nitrogen sealing
Control box operation；
4th step after nitrogen blocking is higher than slag scraper, can be operated slag scraper armful folder button and scraped in oxygen rifle uphill process
Slag operation；It scrapes slag and finishes and open slag scraper immediately；
5th step, slag scraper must be in an open state before oxygen rifle declines；Under teleoperation mode, system is by program according to drop rifle
Signal carries out chain；
As preferred embodiment, the oxygen rifle finishes in blowing and carries out scraping slag operation in oxygen rifle lifting process；Slag splashing
The steel slag being wrapped in oxygen rifle after operation can be used as the oxygen rifle protective layer in converting process.
As preferred embodiment, the oxygen rifle its maintenance when, that is, need artificial treatment oxygen rifle glue cold steel or maintenance when,
" local/remote " button on live slag scraper control box must be got to " local " position by operator, avoid master control room personnel
Maloperation causes accident.
Preferably, the Dreg Scraping Device of Oxygen Lance, every the slag scraper obvolvent aperture of inspection in 48 hours, obvolvent aperture is 5-
8mm。
The present invention compared with prior art, slag scraper of converter oxygen lance of the invention:
Artificial the drawbacks of carrying out is needed 1. solving oxygen and robbing dross cleaning, reduces labor intensity；
2. oxygen is robbed and scrapes slag operation region and belong to high temperature, high coal gas region, the application that oxygen robs slag scraper reduces producers' danger
The working time in region improves safety；
Type is safeguarded using prosthetic 3. controlling equipment, electrical control control box and solenoid valve valve station equipment far from high-temperature area,
The equipment such as pneumatic control cylinder, fixture, armful folder sword realize that manpower-free operates.
