图2是闸门(3)处在开放位置的保护性结构示意图。
我们可以注意到,在保护性结构内包含指示装置(5)和辐射传感器(4),在完成检测该过程的热参数之后,发送这些参数到计算机设备(9),计算机设备(9)处理和记录这些参数,用于控制和调节壁表面(8)的工作温度分布。
图2a表示特定的隔离剂(release agent)液体(12)的介入示意图,其目的是从模具(8)中取出很少的热量以减小预热阶段,
图2b表示一般的隔离剂液体(11)的介入示意图,用于正确地执行工艺过程。
在附图中每个单独的细节标志如下:
数字1表示可调节设备,自动地完成由计算机(9)编程的可调节设备探索性偏移(explorative excursion);
数字2是保护性结构;
数字3是闸门;
数字4是辐射传感器,用于检测被检查的过程热参数;
数字5是用于检测的指示装置;
数字6是计算机设备的连接电缆;
数字7是气压管路连接,用于引入空气到保护性结构中;
数字8是壁,应当检测该壁表面上的工作温度分布;
数字9是计算机设备;
数字10是一种装置,在每个循环中用于插入喷雾器到两个对接模具(die halves)之间;
数字11是普通的水基隔离剂液体喷雾器;
数字12是用于预热阶段的特定液体喷雾器。
具体实施方式
该设备按照如下工作:
在该工艺过程的连续运行期间:
-管理可调节设备(1)的自动偏移程序;
-采集和处理由传感器(4)检测的热参数及其温度值的转换;
-观察和映射探测表面(8)上的温度值分布;
-控制和调节该工艺过程以优化工作温度的分布。
在预热阶段:
通过探测性偏移检测模具(8)的热参数,这是借助于连接到保护性结构的可调节设备(1)完成的,该保护性结构(1)包含指示装置(5)和辐射传感器(4)。
传输被检测的数据到计算机设备(9),该计算机设备(9)处理,显示和记录这些参数作为温度值。在每个循环中,比较这些温度值与预定的样本值,用于得到执行反向控制的信号,它作用到运行的工艺过程中。
利用特定的隔离剂液体(12)对运行的工艺过程实施暂时的反向操作(retroaction),其目的是在预热阶段从模具(8)中取出很少的热量,为的是减小所需的循环数目而使模具(8)达到正常的热运行状态,并减少工艺过程中单个循环的时间。
在实现正常的热运行状态之后,通过发送另一个控制信号,实现由计算机设备(9)控制的从特定液体(12)到普通水基隔离剂液体(11)的交换。
展示的这些附图强调该工艺过程的简单性和可靠性,它可应用于冶炼厂,特别是在模铸和模压工厂或在类似的工艺过程中。
应当指出这样一个重要的事实,只有在进行检测时才打开闸门(3),总是可以保护传感器(4)和指示装置(5)免遭冶炼过程中的环境影响。
此外,还应当指出,过程温度值的结果映射可以对现有的过程状态有一个概要的观察。它还可以同时检测可能的临界区域,该区域要求更多地注意冷却系统的调节。
实现本发明可以有各种技术方案以及结构比例和尺寸,它们符合不同的技术需要。
用于检测工艺过程中工作温度分布的所有方法都涉及此处描述的基本特征,它们都应当属于本发明的保护范围。
