Compared with the previous oxygen lance, the use of anti-adhesion steel layer oxygen lance can significantly reduce the number of slag formation, even without slag formation.

Improve steelmaking capacity

Reducing the slag cleaning time of the oxygen lance can significantly improve the production efficiency, ease the production rhythm of steelmaking, stabilize the high pulling speed of the casting machine, easily realize one more furnace of steel every day, and increase the benefit by more than 10 million per year.

Save labor and equipment costs

Slag cleaning staff can be reduced by at least one-third, no longer purchasing slag cleaning tools.

Reduce production safety input and security costs

The working condition of the post is improved obviously, and safety accidents are basically eliminated.

Reduce oxygen lance damage

Reduce The Times of slag cleaning, reduce the rate of oxygen lance damage, avoid quality problems caused by water leakage.

Improve employee happiness

The labor intensity decreases sharply, improves the employee happiness, mobilizes the work enthusiasm, displays the ownership consciousness better, creates the larger benefit for the enterprise.

Reduce dust and protect the environment

Reduce dust pollution caused by cutting lances, and contribute to environmental protection

When the converter oxygen lance is blowing, the lance body is often covered with steel slag, which affects the normal operation of the converter. When this phenomenon is serious, furnace even needs to be shut down.

When the oxygen lance body is covered with steel slag, it temperature of 900℃ above, the slag removal area unbearably high environmental temperature, as a result, the environment temperature in the slag removal area is unbearably high. Workers working in this area need several people to take turns to deal with some of the steel slag. Moreover, the excessive dust and gas content in this area poses a major threat to the health and safety of the workers.

Several generations of steelworkers and technical experts have continuously explored and practiced the problem of oxygen lance slag, with little effect.

Oxygen lance scraper

Advantages: reduce the intensity of manual work.

Disadvantages: it is easy to damage the slag scraper and oxygen lance lifting mechanism, which will cause serious quality and safety accidents.

Effect: high risk, little effect, industry largely abandoned.

The cone lance

Advantage: a small amount of loose steel slag can fall off by itself.

Disadvantages: increased investment, but did not solve the fundamental problem

Effect: although there are many applications in the industry, the situation of sticky slag is still serious.

Slag antiadhesion paint

Advantages: it is easy to clean up after gluing the steel slag.

Disadvantages: every furnace needs brushing, tedious operation, the operator is in a precarious state of work for a long time

Effect: difficult to popularize and apply
