Empleo de la cáscara de arroz en la fundición de piezas de acero al carbono

feeding auxiliary materials perform a very important role in improves technological efficiency of carbon steel casting parts process. in this article are exposing the first results in the rice husk using as an insulating material in such process. the variables sleeve thickness and covering thickness' influence were evaluated in six combinations by means of experiments. in sleeves preparation was used crushed rice husk, which was agglutinated with sodium silicate, compacted and hardened with co2, meanwhile as covering it was uses without previous preparation. the mayor liquid steel delivering level was get employing 65 mm sleeve thickness and 85 mm covering thickness. the asaf value generated for experimental variants was equal or inferior to 0.48.
