随着改革开放的深入和国民经济的迅速发展,我国对小型材的需要量与日俱增。为了适应市场对小型材需要量增长的需要,太原重型机器厂于1991年11月开发出5.5MN轻合金型材挤压机。试车结果证明,该挤压机技术性能完全达到了设计要求。该挤压机主要用来挤压各种小型铝棒、铝合金棒、型材和各种中空异型材。该挤压机的特点是:采用整体铸造框架,结构紧凑,制造、安装精度高;挤压筒加热为碳化硅壳体电热式,寿命
With the deepening of reform and opening up and the rapid development of the national economy, the demand for small sections in our country is increasing day by day. In order to meet the market demand for small sections of the growth needs, Taiyuan Heavy Machinery Plant in November 1991 to develop a 5.5MN light alloy extrusion machine. Test results show that the technical performance of the extruder fully meet the design requirements. The extruder is mainly used to squeeze all kinds of small aluminum rods, aluminum rods, profiles and a variety of hollow profile. The extruder is characterized by: the use of the overall casting frame, compact structure, manufacturing, installation of high precision; extrusion tube heated silicon carbide shell electric, life
