Cylindrical pocket block Ladle Shroud Al2O3 Submerged Entry Nozzle
Product introduction
Block brick is built at the bottom of the sheng steel barrel, fixed nozzle brick refractory brick. The role of the block brick is to fix the position of the nozzle; Easy to disassemble and install water mouth; Support the lower end of the plug rod during pouring; After pouring, make sure the plug rod slides to the nozzle along the arc surface to cut off the injection flow. Block brick material can be clay, high aluminum or do not burn high aluminum.
Product Feature
1,Mainly used for pouring high-grade steel, special steel, automobile plate, stainless steel and other special purpose steel.
2,The composite carbon-free lining material can effectively prevent Al2O3 and TiO2 from being blocked by deposition on the inner wall of the nozzle.
3,The composite material of imported zirconium-carbon slag line greatly ensures the corrosion resistance and thermal shock stability of the slag line.
4,The Al2O3-C/ZrO2-C composite slag line was designed and manufactured by using a porous Al2O3-C layer on the inner side of the nozzle slag line based on the principle of functional gradient composite.
5,The reinforced material of the mouth of the bowl has the same life span as the slag line.
6,Professional structure design, optimize mold flow field, improve casting billet quality.
