Coneplast - to prevent initial slag carry over!

The Coneplast^TM  system is a newly developed system to prevent the initial slag to be poured out from the converter at the beginning of the tapping. At the beginning of the tapping process, a quantity of slag will run through the taphole. In order to reduce the quantity of slag the taphole is temporarily closed which allows the slag to be kept from the taphole at the tapping beginn.
The Coneplast^TM system reduces the slag carryover to a minimum.Effective slag control should result in better refractory performance of the tap hole and ladle lining and other refractories used in down line secondary treatment stations.
The Coneplast^TM system will prevent any slag entering the taphole on tilting the vessel regardless of the wear pattern or type of the taphole.With the help of an installation applicator the plug is pushed from outside of the converter into the hot region at the end of the taphole and with help of the applicator squeezed so that the taphole is completely plugged. On tilting the converter only steel comes into contact with the plug at the top of the taphole.
The Coneplast^TM stopper breaks down by the Ferro static pressure in a very short time leaving a clean taphole.

Advantages of the Coneplast^TM system

1. Protection of the tapping steel against slag contamination - approx. 500 kgs of slag can be retained giving lower oxygen and phosphorus levels. Some users claim a reduction of 0.3-1.0 phosphorus-points in the steel analysis.

2. Taphole kept free of slag and steel during blowing.

3. Increase of taphole life up to 5 heats.
4. Control of initial surge of steel stream.

5. Breakdown of plug by Ferro static pressure can be adjusted from between 5 and 45 seconds.

6. No deterioration in performance if plug is left in taphole for prolonged periods.
7. Customers report increase of ladle bottom life of between 5-8 heats and increased lifetime of the ladle lining as a result that the steel stream did not hit the ladle lining during the tapping process.
8. Higher rate of ladle opening.
9. Cleaner ladle top.
10. Environmentally friendly due to the reduction of air pollution from the taphole.

The system is patented world wide under WO93/20246, US 6241941 B1, … in more than 26 countries
