| 如图2-3,d所示，用电炉将废钢熔融成1500-1600℃的钢液，然后在钢液表面上，以一个高速旋转的熔抽轮接近钢液，熔抽轮上按照所需钢纤维的要求，刻出许多槽形。当溶抽轮下降到液面时，钢液被槽刮出，被高速旋转的熔抽轮的离心力抛出，以10000℃/秒的速度冷却成形.熔抽轮内必须通水，以保持冷却速度。 As shown in Fig. 2-3 and d, scrap steel is melted into molten steel at 1500-1600 C in an electric furnace. Then on the surface of molten steel, a high-speed rotating melting pulley approaches the molten steel. On the melting pulley, many grooves are carved according to the requirements of the required steel fibers. When the dissolving pulley drops to the liquid level, the molten steel is scraped out of the groove, thrown out by the centrifugal force of the high-speed rotating melting pulley, and cooled to form at a speed of 10000 C/s. Water must be flowed through the melting pulley to maintain the cooling speed. 熔抽法生产钢纤维是目前世界上最有前途的钢纤维生产方法。它的原材料来源广泛，各种废钢都可利用.由于原料成本很低，制造工艺简单；生产效率很高，因此，这种钢纤维价格最便宜。由于熔抽法利用电炉熔化钢水，因此可以较方便地调整钢液的化学成分，从而生产出各种材质的钢纤维和其它金属纤维。改变熔抽轮上刻槽尺寸，熔抽轮的转速和浸入深度，就可以改变钢纤维的几何寸。这种方法免除了上述三种方法从炼钢到轧钢、拨丝（或轧板）等繁杂的过程，使熔触钢水一次成形，加工成产品，其经济效果是很显著的。 Melting-extraction process is the most promising method of steel fiber production in the world. It has a wzhushifen.07858.netjubingxi.07858.netguolvqiy.89ix.comjiezhifab.89ix.comyouxiangy.89ix.comshiyanc.89 ix.comide range of raw materials, all kinds of scrap steel can be used. Because of the low cost of raw materials, simple manufacturing process and high production efficiency, this kind of steel fiber is the cheapest. Because the melting and pumping method uses electric furnace to melt molten steel, it is convenient to adjust the chemical composition of molten steel, thus producing steel fibers and other metal fibers of various materials. The geometric inch of steel fibers can be changed by changing the groove size on the melt pulley, the speed of the melt pulley and the immersion depth. This method eliminates the complicated process from steelmaking to rolling, drawing (or rolling) and so on. It makes molten steel formed once and processed into products. Its economic effect is remarkable. |
