and performance Conical Oxygen Lance with no horizontal weld seams

SWE Conical oxygen lance with no horizontal weld seams

Products Structure:

The national patented product------ conical oxygen lance with no horizontal weld seamsis the substitutes of straight lances, and it has filled the gap in the history of the world’s steel----making technology of the world, having a wide horizon of development in the market.It is made of seamless steel pipe. The lower part of the lance is of conical shape, the upper part is bigger in diameter and the lower is smaller in diameter, which can make the lance working safely and efficiently.

The theory of steel slag fall off from Oxygen Lance:

Some certain steel slag is accumulated from blasts on the taper lance segment. After the lance is lifted, clearance between the steel slag and lance appear, and then cracks will appear between parts of the steel slag and the lance after the steel slag has been cooled by the circulating water. Parts or all of the steel slag sticking to the taper lance segment will fall off from the lance due to the steel slag being expanded because of sudden heating and due to repeated washing by the liquid and steel slag

Products Feature:the appearance of the conical lances has solved the problem of the welding slag sticking to the lances. The feature as follows:

1. Steel slag free falls off from the conical oxygen lances, solving the problem of shutting down the converter for treatment and can’t make steel continually.
2. The conical oxygen lance with no horizontal weld seams can save the charging loss for 0.58ton everyday, decreasing the charging of recycling the second time and energy consumption of smelting repeatedly.
3. No workers are needed to clean the slag on the converter. Burns and scalds and even death are avoided.
4. We can smelt one more converter of steel everyday (24 hours), increasing products and income for company.
