Ladle Nozzle Refractory Upper And Collector Nozzle
Description
Ladle nozzle is composed of upper and lower sliding plates and 4 refractory bricks for the upper and lower nozzles. The pouring of each ladle of molten steel must pass through the upper and lower sliding plates and the upper and lower nozzles, so they are very strict. Firstly, they must have sufficient strength at high temperatures to withstand the static pressure of molten steel. Secondly, the upper and lower sliding plates are required. The sliding surface should be very smooth, flatness should be high, to ensure tight contact, to ensure that no molten steel leaks during the pouring process, but also to be resistant to erosion, erosion, and good thermal stability, so as to withstand sudden changes in temperature. Erosion and slag erosion.
Features
(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.
