On October 20, the parent-child interest group of the labor union of the Municipal Audit Bureau organized member families to enter Ningbo Iron and Steel Group and opened a journey of "how steel is tempered".

After a simple ice-breaking introduction and safety notification course, the research group first came to Ninggang Exhibition Hall and Innovation Exhibition Hall. Here, a vivid picture, a paragraph of precious image data, and a detailed text introduction, clearly show you how "Ningbo Steel" manufacturing gives play to the location advantages of Ningbo, and step by step on the innovation road of building a domestic fine steel intelligent base. Subsequently, in the Group's intelligent control center, the students also experienced the scientific and technological charm of "Ningbo Steel 3D Visual Display System", understood the intelligent creation and remote control technology, and felt the management mode of steel process in modern unmanned factories.

Leaving the exhibition hall, with the sightseeing car to visit the vast factory space, intuitively feel the grandeur and precision of the steel plant equipment. After entering the production workshop, the children wearing hard hats were shocked by the modern steel production equipment and orderly production scene. Under the leadership of Ninggang's professional narrators, everyone had a deep understanding of the steel production process, from the input of raw materials to the hot hot metal oven, to the birth of the final finished steel, every link is full of the power of science and technology. The members of the research group witnessed how the hot molten steel went through a series of complex processes and eventually became high-quality steel plates, which also made everyone deeply appreciate the hard work of the workers and better understand the difficulty of steel production.

Finally, the children in the steel knowledge answer interactive area of the electronic answer game competition, and under the guidance of the staff, personally built a steel scene model, blast furnace, blast furnace bin top, charging belt, coal bunker and other small modules in the shape of the hands, the children not only learned valuable knowledge, but also harvest their own iron making building model.

Through field observation and study, the member families experienced the process of steel smelting and entrepreneurial struggle, gained a new understanding of the scientific and technological innovation of modern industry, and stimulated the next generation's interest in learning and exploration of science and technology.
