At present, the converter top-blown oxygen steelmaking technology is widely promoted and applied in most domestic steel mills, and the oxygen blowing at the top accelerates the rhythm of steelmaking. However, in the fast-paced converter smelting process, the phenomenon of oxygen gun sticking steel (sticky slag) often occurs. As the main carrier, the oxygen lance is not only subjected to high temperature heat radiation of 2500 °C during the blowing process, but also to withstand the intense erosion of steel and slag. Due to the limitations of the working surface, as well as the mistakes of the gun handling or other reasons,it is easy stick to steel. These will not only affect the oxygen supply effect in the blowing process, but also shorten the life of the oxygen lance nozzle. When the situation is serious, the slagging is too thick to lift the oxygen lance, so the furnace can only be shut down, which not only reduces the operating rate of the converter, but also causes great losses to production.
Reasons for sticking steel to oxygen lance:
(1) During the blowing process, the slag is not well permeable, and the fluidity is poor, so the molten metal surface cannot be well covered.
(2) The gun position is too low, causing the slag to “dried back”. The metal splash is severe and adheres to the oxygen lance.
(3) The nozzle structure is unreasonable.
(4) The industrial oxygen pressure also has a certain influence on the sticky slag of oxygen lance.
Damage of sticking steel to oxygen lance:
(1) Oxygen gun slag causes local heat dissipation of the gun body, leads to gun burning and high replacement frequency of oxygen gun.
(2) It is very difficult to remove the steel slag mixture stuck on the oxygen lance, increasing the labor intensity of the workers.
(3) When the slag sticking (steel sticking) of the oxygen lance is serious, the gun body will become thicker, which may cause the failure of oxygen gun rising and falling, and affect normal production.
Characteristics of our company's new refractory for converter oxygen lance:
(1) Green, environmental protection, no pollution, does not affect the quality of the steel itself.
(2) Reduce the thickness of the sticky slag, easy to clean, and reduce the labor intensity of workers.
(3) Increased the use rate of the oxygen lance, increased the converter production capacity, and reduced the production cost.
(4) Preventing the molten iron from splashing, causing melt leaking oxygen lance, effectively protecting the smoothness of the lance, thereby enhancing the safety of production.
The new refractory for converter oxygen lances developed by our company meets the European E0 standard. Environmental protection, no pollution and odorless. The promotion and application of this new product guarantees the efficiency of steel smelting and meets the needs of the development of the steel industry.
