• Lime

      Limestone is the raw material used for burnt Lime and Calcium Hydroxide. If heated to over 900° C limestone dissociates Carbon Oxide, resulting in burnt Lime (CaO). This takes place in shaft furnaces, rotary kilns or fluidized bed furnaces at temperatures ranging between 900 and 1,400° C, depending on the quality requirements.

      The properties of the burnt Lime depend on the burning temperature and dwell time in the kiln. High temperatures and long dwell times produce less reactive burnt lime (dead-burnt lime). However, the soft burnt Lime produced at lower temperatures is extremely reactive. Calcium Hydroxide – Ca(OH)2 is produced by reacting burnt Lime and water.
      Burnt Lime is an outstanding desulfurization reagent used by the steel industry but needs to be processed first. ALMAMET has the required know-how to transform the burnt Lime into an effective and reliable desulfurization reagent. The Lime’s desulfurization effect can be further enhanced by adding various metallurgical additives.

    • Beyond that, ALMAMET has developed technologies required to transform the unwanted undersized particles of the converter Lime into highly effective desulfurization reagents for the steel production.
