本文所介绍的高炉称量系统微机控制装置可同时控制12台秤的称量过程,自动记录各入炉料的称量结果以及进行称量补偿计算、终点控制。该装置能满足工艺要求,抗干扰能力较强,入炉料稳定、准确、均衡,无累计误差,长期使用可降低焦比,增加产量。初步估算,可年创利10万元左右。 This article describes the blast furnace weighing system microcomputer control device can simultaneously control the weighing process of 12 scales, automatically record the weighing results into the charge and weighing compensation calculation, the end point of control. The device can meet the technical requirements, strong anti-interference ability, into the charge stable, accurate, balanced, no cumulative error, long-term use can reduce the coke ratio, increase production. Preliminary estimates, the annual profit of about 100,000 yuan.
