| 1. | Reasons and preventing measures of breakout in slab caster 连铸板坯漏钢的影响因素及防止措施 |
| 2. | Application of a system predicting slab breakout in production 板坯漏钢预报系统在生产中的应用 |
| 3. | Prediction of steel breakout base on grey relation and correlation clustering 基于灰关联聚类的连铸漏钢预报系统 |
| 4. | Breakout is the most catastrophic incident in the continuous casting process 在连铸生产过程发生的各类事故中,损害最严重的便是漏钢事故。 |
| 5. | According to the principle of sticking propagation , the parameters for breakout forecast system have been analyzed and modified in this paper , and some further improvements have been put forward later 根据粘连扩散理论,对漏钢预报系统参数进行了分析和修改,并提出进一步改善的方法。 |
| 6. | By the first method , many models describing the mechanism of breakout have been reported in our country and overseas . not all these models have the same opinion and their calculated results are also not accurate 在第一条途径上,国内外报道的漏钢形成机理模型很多,各种理论不尽一致,也没有精确的定量计算结果。 |
| 7. | To be concrete , the principle of the system is just like this . whether breakout occurs or not is judged by expert system using two kinds of knowledge : neural network and knowledge base 具体来说,本系统的原理就是将神经元网络的输出和知识库的知识输入到专家系统中来,由专家系统来进行综合评判,判断是否会发生漏钢事故。 |
| 8. | The mechanism of breakout was analyzed from the viewpoint of the behavior of liquid steel meniscus in this thesis . research shows that the damage of liquid steel meniscus is the direct cause of a breakout , and many countermeasures of improving the property of liquid steel meniscus are proposed 本文结合钢液弯月面行为分析对漏钢形成机理进行了探讨,认为弯月面的破损是漏钢形成的直接起因,并提出了一系列改善钢液弯月面性能的措施。 |
| 9. | Function of the system : 1 . to give the possibility of breakout and provide operational suggestions . 2 . training new neural networks , testing the existing neural networks in the system and modifying the structure of neural networks 本系统具有以下功能: 1 、给出漏钢可能发生的危险度,适时报警并给出操作建议; 2 、可进行新的神经网络的训练、系统内部的神经网络的测试和网络结构的调整; 3 、良好的人机对话窗口,可使操作人员方便地录入系统所需数据。 |
| 10. | There are two methods to avoid or reduce it now , one is to deeply study the mechanism of breakout so as to get rid of the causes of breakout in process ; the other is to develop techniques of the breakout prediction in order to detect the signs of breakout within the mold , so that measures can be taken to prevent it 为了避免或减少这类恶性事故的发生,目前通常采用两条途径,其一是深入地研究漏钢的形成机理,以便在生产过程中杜绝产生漏钢的条件;其二是开发漏钢预报技术,检测在结晶器中出现的漏钢征兆,然后采取措施避免漏钢事故的发生。 |
