I found it online, for reference only. Students majoring in building materials visited Chongqing Jiang Run Cement Plant for professional cognitive practice. At 7: 30am on February 23rd, 2009, the cognitive practice of building materials specialty organized by the College of Materials Science and Engineering started in front of the Building Materials Laboratory Building in Zone B ... More than 20 junior students from four classes of Building Materials Department in 2007/kloc-0, led by teachers Wan Chaojun, Li Xiaochun, Liu Fang, Zhang Jianxin and Yu Xingang, who were in charge of the internship of the College, visited and studied in Chongqing Jiang Run Cement Factory, Yan Jia Town, Changshou District, Chongqing, for professional understanding. After an hour's drive, the internship team successfully arrived at Chongqing Jiang Run Cement Plant. Minister Li, Director Zhou, Engineer Yu, Engineer Yang, Engineer Fan and other leaders in charge of production management in cement plant warmly received our party. Before the internship officially started, the cement factory held a brief meeting for all the students to introduce the factory situation. First of all, in the conference room of the cement plant, Minister Li first introduced us to the requirements of the production management of the plant, with special emphasis on the safety issues during the internship. Remember to wear safety helmet and non-slip shoes; Don't chase and fight in the production area; Do not touch or touch the production equipment, and keep a certain distance; At the same time, we are asked not to throw peels around in the factory to keep the factory clean. Subsequently, Director Zhou introduced the equipment configuration, process technology and raw materials used in each link of the cement plant in the form of simulation diagram. After the meeting, the technical director of the factory led everyone to go to the factory workshop in class, visit, explain and answer questions, mainly introducing production technology, production technology and product performance. At the same time, the teachers led by each class supplemented and answered some questions and provided necessary guidance during the whole process. According to the production process of "raw materials (limestone, clay raw materials and iron raw materials) crushing-raw meal grinding-raw meal homogenization-(raw coal) coal grinding-preheater, calciner-rotary kiln-clinker silo-mixture-gypsum-cement mill-cement silo-packaging silo (or bulk)-leaving the factory", we visited Jiang Run Cement Plant/KLOC-which is producing at full capacity. During the whole visit, the technicians of the factory mainly introduced the working principle, equipment configuration, energy utilization, waste gas treatment and quality inspection of each equipment, and enthusiastically answered various questions raised by the students. It is the first time for most students to go to the factory to watch each working section in the actual production state, and to get close to the actual production, showing great curiosity. During the whole visit, the students put forward their own doubts based on their knowledge, consulted teachers and technicians, and got satisfactory explanations; At the same time, it also puts forward its own views on related equipment and technology, which deepens the actual understanding of cement production. The internship ended successfully at 1 1: 00. The leading teachers and visiting students expressed their heartfelt thanks to the factory for its support and help. Then everyone boarded the bus in class order, and the teacher who led the team carefully counted the number of people in each car and returned to school smoothly. In the afternoon, after a short rest, everyone carefully sorted out the internship notes and carefully completed the internship diary and report according to the teacher's requirements. Through this professional understanding practice, teachers hope to make students understand the production and production process of building materials products, know building materials products and raw materials, production equipment and operating conditions, and hope to make students have a perceptual understanding of main building materials products and production, initially establish the concept and impression of building materials manufacturing technology, and lay the foundation for learning professional basic courses and specialized courses.
