During the 1980's a development was made to eliminate some of the time lost when the vessel was turned down for sampling and temperature check. A sub-lance was developed with automatic sampling which also saved on the analyses times in the laboratory.Safer and quicker.

Very accurate animation of BOF process. Can be suggested to fresher to watch it & understand.👍

can u tell me what kind of software u use to make this amazing animation?

Thank you!

Nice explaination

thank u legend!

👍👏 Thanks 😊

Nice

Dumping slag goes after pouring metal into the metal ladle. But not before.

Here in Brazil, I never saw a BOF dump the slag before tapping the steel.

The plug on the tap hole is usually made so that it will not dissolve until the heated steel gets to it. Since the slag is of cooler temperature than the steel itself, you can tip it and the plug will hold until enough of the liquid metal moves over the hole. Essentially the plug acts as delay timer giving you time to tip the furnace enough to submerge the path to the hole in molten steel before it gives way. Then you tap as normal.

Excellent..

Can you explain what the N2 slag splashing is needed for? Thank you in advance

Ld furnace shell is lined with magnesite based refractory bricks. They are prone to thermal cycle, chemical attack and mechanical impact. To reduce wear rate of bricks, slag coating is done after every tap. Left over slag inside furnace is splashed by blowing nitrogen and a layer of slag deposited on bricks.

Can high carbon steel be converted to low carbon steel this way after recycling?

Nice video

What is PTP?

Someone who can explain to me, the way they used the slag stopper ???

Density of slag stopper is in between metal and slag densities. It floats at the interface of slag and metal. As metal drains out and slag about to come, stopper closed tap hole opening.
