Zhu Xizhi, a doctor of materials science, accidentally traveled through the Ming Dynasty and activated the "furnace temperature Tianyan" miraculous power, and was able to talk to Song Yingxing, the author of "Tiangong Kaiwu", through the air. Faced with the smoke and dust that obscured the sun and wasted resources in the traditional iron smelting method, she used charcoal as a medium and preached under the sky: she used a bellows to simulate overhead oxygen blowing, used limestone to remove phosphorus and sulfur, and even turned iron slag into enamel, turning waste into treasure. When "pig iron pouring" meets modern recycling technology, the kiln fire in Jingdezhen reflects the prototype of green metallurgy. Let's take a look at how Zhu Xizhi stirred up the industrial situation of the Ming Dynasty. Between steel and kiln fire, he left the mark of environmental protection on the budding capital, and finally added the "circulation" chapter to "Tiangong Kaiwu".
