Moulds for casting EXTENDED castings from aluminum alloys with a wide range of crystallization

摘要

Reschenie relates to the foundry, in particular, to the design of runner system molds.; Proposed profit positioned over thermal cast nodes on the working surface of the lower mold, under the profits install exterior refrigerators, in addition, offers the optimum ratio of areas of cross-sections of the riser, sprue stroke and feeders, as well as the ratio of the distance between the axes of profit to the above casting height.; The technical result - reducing shrinkage type defects gas porosity, increased yield.; 1 SP f-ly 1 Fig.
