上海第五钢铁厂冷拉型钢分厂φ80mm双曲线矫直机,在矫直各种型钢棒材工作时,产生很大的撞击和传动噪声。经有关环境监测部门测定;空车单机运转时其等效A声级为90～96分贝,其负载运转时噪声达100分贝(A),脉冲则高达107～110分贝(A),严重影响操作环境和工人的身体健康。目前,冶金,机械行业的矫直机,降噪问题都未获解决,国外也无借鉴。上钢五厂和上海星火铁工厂等单位共同协作,对双曲线矫直机的
Shanghai Fifth Steel Plant cold-drawn steel plant φ80mm hyperbolic leveler, straightening all kinds of steel bar work, have a great impact and transmission noise. The relevant environmental monitoring department measured; empty car stand-alone operation of its equivalent A sound level of 90 to 96 decibels, the load operation noise up to 100 decibels (A), the pulse is as high as 107 to 110 decibels (A), seriously affecting the operation Environment and the health of workers. At present, metallurgy, machinery industry straightening machine, noise reduction problems have not been resolved, there is no reference abroad. On the steel plant and Shanghai Xinghuo Iron Factory and other units work together to hyperbolic straightening machine
