| 不同的钢丝切割钢纤维的工艺直接影响着其钢纤维混凝土的质量。为了更好的适应其使用,我们就给大家介绍一下其切割规格。 Different steel wire cutting technology directly affects the quality of steel fiber concrete. In order to better adapt to its use, we will introduce its cutting specifications. 钢丝切断法一般用小直径0.4-0.8mm的冷拔钢丝作为原料,并且按照规定的长度把钢丝切成短钢纤维（常见的有端钩型钢纤维）。加工手段可以用切刀、冲床,常用旋转刀具切断。 The steel wire cutting method generally uses cold drawn steel wire with small diameter of 0.4-0.8 mm as raw material, and cuts the steel wire into short steel fibers (common end hook steel fibers) according to the specified length. Processing means can be cut by cutting knives, punches and commonly used rotary tools. 用这种方法生产钢纤维的抗拉强度,远高于其它方法加工成的钢纤维,可达1000-2000MPa。但是冷拔钢丝价格昂贵,这种方法生产的钢纤维成本较高。并且另一缺点是表面较光滑,与混凝土等基体的粘结强度较小。而为改善这些缺点新的切割方法开始出现。 The tensile strength of steel fibers produced by this method is much higher than that of steel fibers processed by other methods, reaching 1000-2000 MPa. But cold-drawn steel wire is expensive, and the www.penwuganzaojii.cnwww.gangchensu.cnwww.chenban.net.cnwww.taocichenban.cncost of steel fiber produced by this method is higher. Another disadvantage is that the surface is smooth and the bond strength with concrete and other substrates is small. In order to improve these shortcomings, new cutting methods began to appear.www.zhutiezhamen.net.cnwww.buxiugangwanguan.cn 1.波形法:切断钢丝前,用进给钢丝的夹送辊将钢丝压成波形后再切断; 1. Waveform method: Before cutting the steel wire, the steel wire is pressed into a waveform by a pinch roller feeding the steel wire, and then cut off. 2.压棱法:切断钢丝前,用进给钢丝的夹送辊在钢丝上压出棱形凹坑; 2. Prism pressing method: before cutting the steel wire, the prismatic pit is pressed on the steel wire by the pinch roll of the feeding steel wire. 3.弯钩法:切断钢丝前,用进给钢丝的夹送辊等距离地压出弯钩状再切断。 3. Bending hook method: before cutting the steel wire, press out the bending hook shape equidistantly with the pinch roll feeding the steel wire and then cut it off. |
