在特钢企业里因高速钢材料的改锻质量不高,影响了切削刀具的使用寿命,以致废品多,浪费了材料。为此,本文详细地总结了高速钢材料有关改锻技术等问题,以便提高改锻质量,从而提高刀具的使用寿命,节约金属材料,提高企业的经济效益。1、高速钢材料改锻目的。高速钢是有于高速切削的刃刃具钢。切削速度达到50—80m/min 时,刀具刃部的温度增至500—600℃时,仍能保持较高的硬度(HRC60左右)。因此,制造车刀、铣刀、钻头、滚丝轮、圆锯等高速切削刀具都采用高速钢。
High-speed steel in the special steel company due to the quality of the reform is not high, affecting the life of cutting tools, resulting in more waste, waste of materials. Therefore, this paper summarizes the problems of the high-speed steel materials such as the reforming technology in detail, in order to improve the quality of the reforming forging so as to improve the service life of the tools, save the metal materials and improve the economic benefits of the enterprises. 1, high-speed steel materials forging purposes. High-speed steel is cutting edge with high-speed cutting tool steel. Cutting speed reached 50-80m / min, the blade edge temperature increased to 500-600 ℃, still maintain a high hardness (HRC60 or so). Therefore, the manufacture of turning tools, milling cutter, drill, rolling wheel, circular saw and other high-speed cutting tools are used high-speed steel.
