In the western Sichuan Province, Panzhihua City is a large industrial city and an important transport hub. It is known for its iron and steel industry and is listed as a major steel city in China. Panzhihua Iron and Steel Engineering (PISI) is the symbol of the iron and steel industry of Panzhihua City.
PISI is the largest iron and steel engineering project in western China. It was established in 1953 and is now the largest iron and steel enterprise in Sichuan Province. PISI was formerly known as Jiuzhou Iron and Steel Factory, which later changed its name to Panzhihua Iron and Steel Engineering. The core of the project are the two blast furnaces that were built in 1954. These two furnaces have produced millions of tons of iron and steel. In the process of production, PISI has made a great contribution to the country and to the people in the western part of Sichuan province.
The main production process of PISI is sintering and sinter pellets. The ore and pellets are conveyed to the two blast furnaces, and then the hot air is blasted into the furnaces to heat the ore and form the sinter pellets. After that, the hot liquid iron is decanted with a ladle and charged into a converter, so that the impurities present in the ore can be further cleared out. Then the steel is separated out and water-cooled after it has reached a certain temperature.
The main products of PISI are high-quality pig iron and silicon-manganese, which are widely used in various industries. Besides, the products of PISI are also used to produce high-strength and high-temperature steel, as well as bridge steel. In addition, PISI is also producing large quantities of metallurgy sludge and slag. These materials can be used for road construction, soil conservation, and more.
In recent years, PISI has been actively promoting technological reforms, modernizing its production facilities and expanding its production capacity. The introduction of an automatic continuous casting production line and a new set of rolling mill equipment has greatly improved the production efficiency and, at the same time, allowed the production of better quality and even more varieties of steel products.
Today, PISI has become an important and reliable supplier of iron and steel, contributing to the countrys domestic and international economic growth. With advanced technology, comprehensive environmental benefits and steady development, PISI will continue to be a leading force in the iron and steel industry of Panzhihua City and the whole Sichuan Province.
