Nichtmetallische Kühlstab für Hochofen

Nonmetallic stave is made with advanced technology,consisting of pretreated special refractory as the main body,thick seamless steel tube as water-cooling elemment,steel plate as farmework.It constitutes a new-type structure comducting cooling walland blast furnace lining.The use of special refractory characterized by being high heat conducting,high temperature resistant,wear resistant,caustic slag-resistant,alkali metal-resistant and resistance to the corrosion of noxious gas reduces the breaking speed while preventing water cooling tube from damaging easily and keeping water flowing smoothly.A suitable cooling strength makes it have aservies life same as that of crucible and furnace bottom,eliminating the need of repairing within 8 years of working.
