Abstract

PURPOSE: To obtain high calcium carbonate which has a quality similar to a commercially available high pure product and which is particularly useful as an accelerator for desulfurizatin agent of hot iron, by introducing granulated carbide slag in a rotary kiln and blowing CO and O2 into it to carry out carbonation within a specified temp. range.
CONSTITUTION: A granulating assistant such as PVA etc, or water is added to carbide slag in an amount of 0.1W10wt% to granulate it at a size of 5W50mm. Granules are then introduced from one end of a rotary kiln, and CO and O2 are blown from the other end to burn CO and maintain them at the temp. of 500W900°C in CO2 atmosphere. Thereby, Ca(OH)2 which is a main component of carbide slag is carbonated. Light calcium carbide obtd. by this carbonation is anhydrous and a light product with an average granular size <1μ.
