Product Description

Tundish Nozzle for Steelmaking
 
Currently, our products Tundish nozzle ( metering tundish nozzle, non-swirling tundish nozzle, CNC nozzle, tundish nozzle plate etc ) have been used in many carbon burning furnaces, CFB boilers in power plant, cement rotary kilns, non-ferrous metal melting furnaces, blast furnaces, hot-blast furnaces, coking furnaces, steel ladles, glass melting kilns and other high temperature industries all over the world.

Tundish metering nozzle is used for tundish, and it has great performances of purifying liquid steel, prevent liquid steel oxidation, with good liquid steel washing resistance and erosion resistance.

Features of continuous casting / tundish double sizing nozzle:
high refractoriness, thermal shock performance, anti-erosion, erosion resistance, small diameter change, long service life and so on.
