我厂27.56平方米(长19.8米宽1.39米)步进炉是1200吨二辊叠轧薄板轧机的配套设备,该设备专门生产热轧矽钢片。由于热轧矽钢工艺生产的严格性,对步进炉提出了相当苛刻的要求,要求步进炉在一个循环20秒周期内,一次出四块料。板坯为9.8×1030×240毫米,板坯只允许分开平放,不允许重叠歪斜和振动。即要求步进炉大型化,高速化,对液压系统提出了大流量,无振动的要求。液压系统的高速、大流量,相应引起了液压冲击振动和噪声。目前在国内步进炉上所用的液压系统中,其线速度较低,一般在每秒90毫米至100毫米之间。就是
Our factory 27.56 square meters (19.8 meters long and 1.39 meters long) is a step furnace 1200 tons two roll lamination rolling mill supporting equipment, the equipment specializing in the production of hot-rolled silicon steel sheet. Due to the stringency of hot-rolled silicon steel production process, the stepping furnace made quite demanding requirements, step furnace in a cycle of 20 seconds cycle, the first four pieces of material. Slab is 9.8 × 1030 × 240 mm, slab only allowed to be laid flat, not allowed to overlap skew and vibration. That is to say stepping furnace large-scale, high-speed, the hydraulic system proposed a large flow, no vibration requirements. Hydraulic system of high-speed, high flow, corresponding to the hydraulic shock and vibration caused by noise. Currently used in the domestic stepper on the hydraulic system, the line speed is low, usually between 90 millimeters to 100 millimeters per second. That’s it
