带锯类钢带的制造主要使用中、高碳冷轧带钢,经热处理以获取一定的硬度,其成品有弓锯、石锯、圆锯、屠夫带锯、木带锯、摩擦锯、机用带锯等,规格品种很多。目前全国带锯产量约为2～3万吨。主要采用淬、回火处理,硬度为HRC45～50。由于锋利度和耐磨性差,使用寿命低,消耗量很大。用国产带锯加工木质较坚硬的进口木材时,其寿命一般为20min～2h。许多用户迫切要求供应硬度为HRC55～60的高质量带锯。
Band saws mainly used in the manufacture of steel strip, high carbon cold-rolled strip, after heat treatment to obtain a certain hardness, the finished bow saw, stone saw, circular saw, butcher band saw, wood band saw, friction saw, machine Band saw, etc., a large variety of specifications. At present, the output of band saw is about 2 ~ 30,000 tons nationwide. The main quenching, tempering, hardness HRC45 ~ 50. Due to poor sharpness and wear resistance, low service life and high consumption. With the domestic wood processing wood imports more hard wood, its life expectancy is generally 20min ~ 2h. Many users are desperate to supply high-quality band saws with hardness HRC 55-60.
