Calcium Ferrite

General Description

Calcium ferrite is produced by melting iron ore and lime in a melting furnace. It is used for phosphorus removal during iron manufacture. Recently it is said that fluorspar, which was usually used, has a negative effect on the environment by emitting fluorine. Calcium ferrite doesn't include fluorine. So it is used as a substitute for fluorspar.

  

Features

Our calcium ferrite is a melting type and a low-melting compound. So it melts quickly after placing inside of furnace. It is a substitute for fluorspar. It doesn't include fluorine. So it is environment-friendly. It has a good phosphorus removal effect.
