Method for calculating oxygen lance height by utilizing incremental encoder

The invention relates to a method for calculating oxygen lance height by utilizing an incremental encoder. The method comprises the steps that a setting point of the oxygen lance height is set, relative height of a lance position of an oxygen lance is set, height, corresponding to each pulse, is calculated, the oxygen lance height is calculated, and blowing height is calculated. According to the method for calculating the oxygen lance height by utilizing the incremental encoder, through the incremental encoder installed on a site, the oxygen lance height is calculated according to calculatingthe pulse number of the incremental encoder, the lance position of the oxygen lance is automatically calibrated, the linkage and the function of each lance position point are realized, the frequent lifting of the lance position is avoided, and the aims of improving the oxygen lance height, controlling the precision and reducing the labor intensity are achieved. 本发明涉及利用增量型编码器计算氧枪高度的方法，包括氧枪高度置位点的设置、设置氧枪枪位的相对高度、计算每个脉冲对应的高度、计
