钢带机主体结构的设计+图纸
这种钢带机可生产非晶钢带。非晶钢带的应用范围很广，意义重大，所以国内的钢铁行业研究单位对这种机器的开发应用非常感兴趣。但他们的机械设计能力较差。由于现在滚动元件的制造技术越来越成熟，所以开发一种准确、稳定的进给机构成为可能。本机构就是用来解决精确定位及稳定性的问题。

Abstract:Strip aircraft is the use of liquid hot metal contact trundle cooling column barrel by the free fall and one kind of mechanical device to produce steel belt. Steel belt's width may the oil molten iron whereabouts mouth control, thickness control determine through the advanced gear that through the power unit, the rolling guide, the ball bearing lead screw, constitutes one to be possible the steel belt thickness adjustment accuracy control micron advanced gear.
This kind of strip machine may produce the crystalless steel belt. The crystalless steel belt's application scope is very broad, the significance is significant, therefore the domestic steel and iron profession research unit is interested to this kind of machine's development application. But their machine design ability is bad. Because present rolling element's technique of manufacture is getting more and more mature, therefore develops one kind accurately, the stable advanced gear possibly to become. This organization is uses for to solve the pinpointing and the stable question.
Key words : strip machine; pinpointing
