Establishing Siemens Company and Innovating Steelmaking Process
What are the inventions of Siemens generators?
1866, Werner-Siemens developed a DC generator, which was originally used for military purposes. After further improving the power and load capacity, he found that this machine also has a wide application prospect in the field of trams and motors. 1879, Siemens installed street lamps for Berlin streets. 1880 elevator manufacturing. 188 1 year, Siemens established the first electronic public transport system, which enabled trams to run in the suburbs of Berlin. Since 1877, the telephone has also joined the company's products. Siemens improved the telephone invented by Graham Bell, but it didn't get a patent in Germany.
This kind of telephone sold more than ten thousand sets in the first three years. Improving other people's inventions is Werner-Siemens' strong point. Through his efforts, the performance of the product has been greatly improved, and it can also avoid the constraints of patent law. Werner-Siemens realized in practice that enterprises must constantly improve the performance of products according to the changes in market demand and give consumers the best products. Of course, this improvement is not only to improve other people's products to expand the product line, but also to continuously improve existing products. Of course, the mining and smelting industries established by Siemens brothers also have to be mentioned. They put forward the open hearth steelmaking method, which directly smelted iron ore into steel by using a high-temperature regenerative furnace, and innovated the steelmaking process. Therefore, Siemens steel plant is also in the forefront of European steel manufacturing industry.
Ernst Werner von Siemens (18 16- 1892), a world-famous German inventor, entrepreneur and physicist, laid and improved submarine and underground cables and wires, built electrified railways, put forward the open hearth steelmaking method and innovated it.
