双旋转毂式矫直机的优化设计

THE OPTIMIZATION DESIGN OF LEVELLER WITH DOUBLE ROTARY HUB

目前电解法作为纯镍生产的主流方法被广泛采用,其主要特点为通过导电棒引导电流,最终将电流导向种板。因此在实际生产中由于受到承重、撞击等各种因素的影响,导电棒会产生形变。因为整个电解过程的效率和自动化程度的提高需要使用满足要求直线度的导电棒,所以一个电解周期后必须矫直产生形变的导电棒。本文以国内某镍冶炼厂中规格为Φ36 mm×3 mm×1 350 mm的电镍导电棒为研究对象,对转毂式斜辊矫直机进行研究,利用优化后的矫直机矫直编为两组的20根电镍导电棒,对矫直后的导电棒进行测量,并分析比较其平直度,从而验证该种矫直机能否完成电镍导电棒的矫直。

Nowadays,electrolytic method is widely used as the mainstream method of pure nickel production.The main characteristic of this method is to guide the current through the conductive rod,and finally the current is guided to the plate. Therefore,in actual production,due to the influence of bearing,impact and other factors,the conductive rod will undergo deformation. Because the efficiency of the whole electrolysis process and the improvement of the degree of automation need to use the conductive rod that meet the required straightness,these conductive rods must be straightened after an electrolytic cycle. In this paper,we study and optimize the operation of the rotary bevel type roller straightening machine by choosing conductivity rod with a size of 36 mm × 3 mm ×1 350 mm in a domestic nickel smelter,using the optimized straightener to straighten two groups of 20 electric nickel conductive rods,measuring these conductive rods,analyzing their flatness,and verifying whether the straightener can complete the straightening of the electric nickel conductive rod.
