METHOD FOR MAKING CONSTRUCTIONAL MEMBER OF POWDERED INITIAL MATERIAL AND EXTRACTOR SUITABLE FOR PERFORMING THE SAME

摘要

FIELD: forming constructional members by pressure die casting, namely method for removing additional matters from blank. ^ SUBSTANCE: method comprises steps of mixing initial components and preparing fluidic mass; making blank of prepared mass by pressure die casting; heating blank at continuously or step-by-step increasing temperature and acting upon it with flow of compressed supercritical treating gas in order to extract part of auxiliary matters. Method is realized in extractor having fluid-tight body embracing working space. Said space is provided at least with one inlet for treating gas and at least with one outlet for waste gas and it has closed opening for charging and extracting blank in lateral boundary wall. ^ EFFECT: rapid removal of binder. ^ 11 cl, 1 dwg, 1 tbl
