Product introduction

 

Alias: Zirconium

 

English name: ferrozirconium

 

Properties: The surface of zirconium is easy to form an oxide film with a luster, so the appearance is similar to steel. It is corrosion-resistant, soluble in hydrofluoric acid and aqua regia. It reacts with non-metallic elements and many metal elements at high temperatures to form solid solution compounds.

 

Introduction Zirconium iron is an iron alloy composed of zirconium and iron, and elements such as silicon and aluminum. The zirconium iron for steelmaking is zirconium ferrosilicon, containing Zr 15% to 45%, and Si 30% to 65%. Produced by the aluminothermic method, it is called zirconium aluminum iron because it contains aluminum, and contains Zr>15%.

 

 

 

Production Process

 

1) Zircon, lime, fluorite, 75% ferrosilicon and iron oxide skin are mixed and smelted in a carbon brick lining arc furnace. After the temperature of the furnace rises to 1700 ° C, stirring and reduction are started.

 

2) When the reduction is completed, the furnace temperature is raised to 1800 to 1900 °C, and the furnace is discharged, slag, and cast. The zirconium-silicon ferrite composition obtained is: Zr 20% to 40%, Si 45% to 55%, Al < 0.5%, P < 0.1%. The zirconium recovery rate is about 55%. The slag contains ZrO 210% to 15%, and the alkalinity is 0.8 to 1.0.

 

Our advantage

 

1. Large goods come directly from refineries or ports, without transit.

 

2. Year-round cooperative fleet, no special fare increase for transportation safety.

 

 

 

 

 

 

 

Zirconium is one of the strongest deoxidizers for steelmaking and a special role for zirconium in steel. Zirconium iron is used as a deoxidizer and alloying additive in special-purpose superalloys, low-alloy high-strength steels, ultra-high-strength steels and cast irons. It is then used in atomic technology, aerospace manufacturing, radio technology, etc. The silicon zirconium iron can be refined by refining the composite Si-containing alloy.
