我厂在去年先后生产了几种易切削钢及炭素工具钢的六角钢,现将我们对轧制和孔型设计的一些体会提出来供大家参考,有不正确的地方希同志们指正。 (一)设备及原料 1.原料:4时的侧吹碱性转炉及电炉钢锭,其钢锭大头边长为107毫米,斜度为0.49％,锭长1200毫米,单重为81.6公斤。 2.设备性能简介: (1)加热炉:有效长度为13070毫米,有效宽度为3170毫米,炉底强度633公斤/米~2。小时,水管距离为65O毫米,是侧出料双排燃煤三段式加热炉。 (2)轧钢机: ①粗轧机:φ400轧机一架,由710KW电动机带动,轧辊转速为99转/分,轧辊尺寸为φ425×1600,高炭钢铸造。
Last year, our factory successively produced several kinds of hexagonal steel for easy-cutting steel and carbon tool steel. Now we put forward some experiences for rolling and hole design for your reference, and correct the place where Greek comrades correct me. (A) equipment and raw materials 1 raw materials: 4 o’clock blowing side of the basic converter and electric furnace ingot, the ingot bulk side length of 107 mm, a pitch of 0.49%, 1200 mm long spindle, single weight of 81.6 kg. 2. Equipment performance profile: (1) heating furnace: the effective length of 13070 mm, the effective width of 3170 mm, bottom strength of 633 kg / m ~ 2. Hour, water pipe distance of 65O mm, is the side of the two-row coal fired three-stage heating furnace. (2) Rolling mill: ① roughing mill: a φ400 mill, driven by 710KW motor, roll speed of 99 rev / min, roll size of φ425 × 1600, high carbon steel casting.
