Product Description

1QC refractory outer nozzle lower nozzle

 

Collector Nozzles/Lower nozzles/Refractory nozzle/Outer nozzle

Adopting tabular corundum, white corundum, mullite as main materials.Choosing good anti-oxidation flake graphite as carbon source, adding aluminum metal powder, silicon metal powder and other additives to increase high temperature performance.Using phenolic resin as bonding which obtains high solid content and high carbon residue. Integrated with steel can to forming or shaping separately under high temperature.

With features of good volume stability, excellent thermal shock resistance, high temperature crushing resistance, anti-erosion, low rate of bore expanding, long service life and wide range application.

Inner Nozzles/ Upper nozzles
Adopting tabular corundum, white corundum, silicon carbide, metal aluminium, high quality magnesite as main materials. 
Choosing good anti-oxidation flake graphite as carbon source, adding small amount antioxidant to increase oxidation resistance. Using phenolic resin as bonding which obtains high solid content and high carbon residue.After forming and shaping, process pitch impregnation according to using conditions.

With features of good thermal shock resistance, high temperature strength, anti-erosion, anti-scouring, long service life and wide range application.

Features: Excellent thermal shock resistance, stable performance, good corrosion and erosion resistance, strong cracking resistance etc.

It is divided in two series of low carbon and medium carbon, and low carbon series has the lower carbon content,so especially suit for metallurgy low carbon steel.Medium carbon series is suit for widely type of steel.
