Product Description
The worldwide percentage of steel and alloy produced via ingot casting has decreased since decades. However some steel and alloy applications will continue to be bottom poured in the foreseeable future.
This includes steel and alloy ingots for intermediate and large forgings for the transportation, oil, heavy equipment and aeronautical industries. Vacuum remelt electrodes and specialty alloys such as nickel based, nickel cobalt, nickel copper and those alloys which can't be economically continuously cast will continue to be ingot cast.
YUFENGREC® offer a complete range of high quality dry pressed Bottom Pouring Refractory Brick , ranging from 42% to 80% in alumina content. included Sleeve Brick, Runner Bricks ,End Runner brick with riser , Bottom Guide ,Central Brick(Spider) , Funel , Round and Square Tube, Tail brick ,well block , stopper etc ...
