发明名称 MANUFACTURE OF CARBURIZING AGENT
摘要 The described process relates to the production of carburizing agents by compacting carbon dusts with a binder, such as hydroxyethyl cellulose, with addition of water and an auxiliary gelling agent. The auxiliary gelling agents used is glyoxal and/or bases of an alkali metal or alkaline earth metal or ammoniacal water. At from 0.5 to 2% by weight the requirement of binder is so small that no noticeable changes in the analytical values for the carbon dust used appear. The molded bodies produced from the compositions are dried at from 20 DEG to 180 DEG C. Calcination is not required.
