LOW CARBON CAST IRON MANUFACTURING APPARATUS USING PRESSURE CASTING DEVICE WITHOUT SURFACE CARBURIZING CAPABLE OF PREVENTING THE CARBONIZATION OF ORGANIC PATTERN BY REMOVING GAS GENERATED FROM FOAMING MODEL TO BE STAGNATED IN AN UPPER PART WHEN MOLTEN IRON IS INJECTED AND MANUFACTURING METHOD THERE OF

摘要

PURPOSE: A low carbon cast iron manufacturing device using a pressure casting apparatus without surface carburizing and a manufacturing method thereof are provided to manufacture low carbon cast iron with anti-carbonized effect of removing surface carburizing by containing less than 1.0% of carbon content, and to prevent a negative effect in which molten iron passes through a coating agent into a sand mold by using a reinforced coating agent.;CONSTITUTION: A low carbon cast iron manufacturing apparatus using a pressure casting apparatus without surface carburizing and a manufacturing method thereof includes a cast steel manufacturing device(A) for a low carbon and a gas collection device(5). The gas collection apparatus which are connected with the upper end of an evaporative pattern of a mold absorbs and removes hazardous gas generated from an evaporative pattern casing process of an organic mold resin and a molten iron by vacuum pressure. The cast steel for low carbonation has carbon content 1.0% or less. A coating agent is the mixture of alumina, zircon, and silica. The coating agent is composed of, in wt%: Alumina 10-40w, zircon 10-40, silica 10-15, and clay 5-10. An evaporative pattern is composed of PMMA(polymethylmethacrylate).;COPYRIGHT KIPO 2013
