随着汽车工业的迅速发展,车辆需求的变化(大吨位、大马力、重型化),对发动机的各项性能要求也越来越高,传统的发动机中使用的铸造曲轴不得不面临严竣的考验。由于锻钢曲轴的一系列优点,球墨铸铁曲轴市场将会面临锻造曲轴市场的严竣挑战,曲轴铸改锻趋势明显。 With the rapid development of the automobile industry, changes in vehicle demand (large tonnage, high horsepower, heavy-duty) have also raised the demands on engine performance. Cast crankshafts used in traditional engines have to face severe challenges test. Due to a series of advantages of forged steel crankshaft, ductile iron crankshaft market will face the challenge of forging crankshaft market, crankshaft cast change forging obvious trend.
