据苏联1983年出版的《轻泡废钢加工用设备》一书介绍,近几年来,苏联开始注重发展三向挤压的废钢打包机。这种新式打包机与普通的二向挤压的废钢打包机相比,因多了一个主压,废钢包块的密度有所提高,而且卸压后膨胀率小,运输过程中不易散包,用于冶炼的经济效益高。 在苏联,目前主要有两种型号的三向打包机,一种是1977年从捷克引进的-1250型打包机,该机安装在伏罗希洛夫生产联合体;另一种是苏联亚速锻压设备厂制造的-1338型(第一台于1978
According to the Soviet Union published in 1983, “light foam scrap processing equipment,” a book introduction, in recent years, the Soviet Union began to focus on the development of three-way squeeze scrap balers. Compared with ordinary two-way squeeze scrap balers, this new type packer has the advantages of increased primary pressure, increased density of scrap blocks, and small expansion rate after pressure-relief, which is not easy to scatter during shipping. For the smelting of high economic efficiency. In the Soviet Union, there are currently mainly two types of three-way balers, one is the -1250 baler introduced from the Czech Republic in 1977 and installed at the Voroshilov production complex; the other is the Soviet Union Forging equipment factory manufacture of -1338 type (the first in 1978
