DESCRIPTION
Collector nozzles for ladles are made from corundum, bauxite, flake graphite, anti-oxidants and phenolic resins. They show features of excellent thermal shock resistance, stable performance, good corrosion and erosion resistance, and strong cracking resistance.
Properties:
(1) Smoothness of sliding surface ≤0.05mm;
(2) High mechanical strength;
(3) Strong corrosion resistance to molten steel and slag;
(4) Excellent oxidation resistance;
(5) Good thermal shock stability.
