The investigation of liquid-moving self-firming mixture for steel casting forms in order to optimize its content

The aim of the optimization of the liquid-moving self-firming mixture (LSM) content together with the regenerated sand for making steel shaped casting forms is discussed. The investigation results of the mixture main technological features during the change of its content are given. The design of mixture main technological features has been done and its optimal content has been defined. The recommendations for the materials doses and the technology of the casting mixture preparation with the regenerated sand have been given.
