摘　　要：在高温合金熔炼中,熔速的稳定性至关重要,但熔速传统计算方法滞后且易受干扰,制约了精细调控,可能导致铸锭缺陷。为实现对熔速的实时精准控制,研究探讨了卡尔曼滤波技术在熔速预测中的应用。卡尔曼滤波通过融合动态模型和观测数据,在噪声环境中提供最优状态估计,可显著提升熔炼系统的响应速度和精度。实验表明,该技术大幅提高了预测熔速的准确性和实时性,减少了滞后和干扰,有效避免了铸锭缺陷。随着技术发展,卡尔曼滤波在高温合金熔炼及其他领域的应用前景广阔,有望推动工业生产的智能化和精细化发展。In the melting of high-temperature alloys,the stability of the melting rate is crucial,but traditional calculation methods are outdated and susceptible to interference,which limits fine control and may lead to ingot defects.To achieve real-time and precise control,the application of Kalman filtering technology in melting rate prediction was studied and explored.Kalman filtering provides optimal state estimation in noisy environments by integrating dynamic models and observation data,which can significantly improve the response speed and accuracy of smelting systems.Experiments have shown that this technology significantly improves the accuracy and real-time prediction of melting rate,reduces lag and interference,and effectively avoids ingot defects.With the development of technology,Kalman filtering has broad application prospects in high-temperature alloy melting and other fields,and is expected to promote the intelligent and refined development of industrial production.
