摘要
介绍了铸件内腔表面因树脂砂芯引起的飞翅缺陷,并对其名称和形成机理进行了探讨。详细叙述了形成飞翅的可能影响因素,包括铸件结构及工艺参数、硅砂、特种天然矿物砂、人造砂、粘结剂、氧化铁、涂料等,并提出了相应的防止措施。
The finning defects on inner surfaces of castings caused by resin sand cores were introduced, their names and definitions were discussed. The possible factors causing finning defects were described in detail including construction of castings, process parameters, silica sand, special natural mineral sand, artificial sand, binders, iron oxides, coating, etc.. The corresponding prevention measures were also suggested.
