我厂冲天炉安装γ射线料位计,解决了料位控制问题,《铸造机械》1975年第2期已有所介绍,现再就其具体问题,进一步说明如下,供参考。一、放射源在冲天炉料线部位相应的炉壳两侧,安装放射源和探头。为了尽量减少对周围操作人员的辐射量,应采用允许的最低射源强度。在安装射源部位的炉壳上,去掉一小块钢板,用一块30毫米厚的薄耐火砖,取代原来部位的较厚耐火砖,按水平测量法安装放射源和探头。用γ射线测量料位的工作原理和射源的安装部位如图1所示。当炉料挡住时,
Our factory cupola installed γ-ray level meter to solve the problem of material level control, “Casting Machinery” No. 2, 1975 has been introduced, and then further on its specific issues, further described below for reference. First, radioactive sources In the cupola line corresponding furnace shell material on both sides of the installation of radioactive sources and probes. In order to minimize the amount of radiation to the surrounding operators, the lowest allowable source intensity should be used. On the shell where the source was installed, remove a small piece of steel, replace the thicker refractory bricks in the original area with a thin firebrick 30 mm thick, and install the source and probe according to the horizontal measurement method. Gamma ray measurement of the working principle of the material and the installation site of the source shown in Figure 1. When the charge blocked,
