Ladle large-scale converter tap slag blocking mechanism (sliding board) inlaid with zirconia plate r

At present, the main products on the market include the upper slide plate inlaid with Fangming high-temperature ceramic high-purity zirconia zirconia ring, the lower slide plate with Fangming high-temperature ceramic high-purity zirconia zirconia plate, the upper slide plate with zirconium plate and the lower slide plate with zirconium plate. , There are several types of upper slide plate inlaid with zirconium ring and lower slide plate inlaid with zirconium cake in the slideway anti-slip area. These different types of inlaid slide plates are used in different types of converters of 120 to 300 tons in China, and the service life can be stabilized at 15 to 18 furnaces when both the slag blocking in the early stage and the later stage are used. If other slag blocking methods are used in the early stage of slag blocking, the life of the later stage slag blocking can be stabilized at about 20 heats or even more than 25 heats.

The advantages of our converter tapping sliding plate slag blocking technology:

①Reduce the amount of slag entering the ladle from the converter;

②Improve the smelting rate of various steels and reduce the phosphorus back into molten steel;

③Improve the alloy yield, save the input amount of deoxidizer and top slag modifier, save the use of converter auxiliary materials, and save production cost;

④Reduce the inclusions in the molten steel and improve the purity of the molten steel.
