Oxygen gun scraper
1. Working principle:
Oxygen gun is an important equipment for converter steelmaking, oxygen gun works at high temperature in the furnace, violent oxidation reaction in the furnace, resulting in the outer steel pipe of the oxygen gun splashed with steel slag of different thicknesses. To a certain extent, oxygen gun nodules are formed. The nodulation was too large for the oxygen gun to enter and exit the nitrogen seal, and the steelmaking was interrupted and the oxygen gun was replaced, bringing production to a standstill.
Self-insured oxygen gun scraper is a special automatic mechanical device developed for oxygen gun slagging, and has obtained a national patent, patent number 200520072031.4. The working principle of the device is that above the nitrogen seal of the oxygen gun, a pair of clamp-type double arms are installed, and the power is transmitted through a special cylinder, and the caliper blade processed from a high-heat-resistant alloy is used to hold the oxygen gun, and as the oxygen gun is lifted, scrape off the steel slag splashed on the oxygen gun.
The use of the oxygen gun scraper will replace the original backward steel brazing and wind pickaxe pounding process, which will save a lot of manpower and material resources, especially save time, improve labor productivity, and truly achieve twice the result with half the effort, so that manual pounding oxygen gun sticky slag has become history.
2. Structural features:
The two arms are designed with the function of upward inclination movement, when the cold steel or nodulation is too large when the work is encountered, the load can be automatically opened and avoided, to achieve the function of protecting the oxygen gun body and the oxygen gun transmission system and the scraper device, so that your scraping operation has no worries.
The patented design of the oxygen gun scraper calculates the bearing capacity of the transmission system of the oxygen gun, the thrust of the two cylinders and the inclination angle of the scraper arms, which ensures the safety and reliability of the device in use.
Self-insured oxygen gun scraper has reasonable design, simple structure, long practical life and easy installation. The implementation of this device will be once and for all.
3. Scope of application
The downward scraping force of the self-insured oxygen gun scraper is carefully calculated and adjustable, so the self-insuring oxygen gun scraper is suitable for any tonnage converter oxygen gun.
It is the only automatic scraping device for oxygen guns suitable for current converters.
