中型轧钢车间生产的各种钢材,冷床,经轧钢机轧制后由热锯机(或剪切机),切成定尺长度,还需要冷却到常温,再进行矫直。轧制后的热轧件冷却时,由于连续生产,一般都是在缓慢的横向移动过程中逐渐冷却的。这种使轧件横向移动并冷却的设备,叫做冷床。
All kinds of steel produced in medium rolling mill are cut by hot saw (or shearing machine) after rolling mill, and it is cut into length of fixed length. It also needs to be cooled to normal temperature and then straightened. After rolling, the hot rolled parts are cooled down gradually because of continuous production. The equipment for rolling and cooling the workpiece is called cold bed.
使冷床区域产生空气自然对流,形成烟囱效应,冷床哪家好,造成冷床上圆钢下部冷却速度过快,出现冷却不均匀,冷床设备,影响了产品的质量。步进翻转冷床利用步距与齿距的差值,使圆钢在冷床上每移动一个齿距,圜钢就滚动了一个角度,避免了圆钢在冷床上的不均匀冷却所造成的质量问题。
The cooling bed area of air natural convection, the formation of a chimney effect caused by the cooling bed bar lower cooling speed, appear uneven cooling effect of the quality of the products. Step by step difference of inverted cooling bed and pitch, the bar in the cooling bed every movement of a pitch, round steel rolling an angle,冷床设备生产商, to ***oid quality problems of round non-uniform cooling in the cooling bed caused by.
针对角钢试生产初期冷床下钢发生倾翻的特点及原因,作业区技术人员指导岗位自己设计制作了防止角钢倾翻装置,通过冷床长度的测量及冷床裙板至冷床齿条距离,选定防止角钢倾翻装置的位置及长度,利用装置自身重力,从而实现角钢的稳定下钢,顺利进入冷床。
The needle angle steel trial production of steel bed early occurrence characteristics and causes of the tilting of the work area, the guidance of technical staff their own design to prevent angle tilting device, by measuring the cooling bed length and bed apron and bed rack distance, the selected angle to prevent tipping device and length of use of the device's own gr***ity in order to achieve the stability of angle steel, ***oothly into bed.
