Развитие Металлургия конспект ​

Answer 1

Ответ:

Основным сырьем для выплавки стали в электродуговых печах, в отличие от конвертеров, является твердая металлошихта, состоящая преимущественно из металлоотходов собственных металлургических производств и поступающего со стороны товарного лома. К регламентируемым показателям качества металлошихты во всем мире относят, прежде всего, такие факторы, как определенность химического состава, насыпная плотность и габаритные размеры отдельных составляющих шихты.

Development of Metallurgy

Metallurgy is the branch of science and technology that deals with the extraction, refining, and processing of metals. It has played a crucial role in the development of human civilization, enabling the creation of tools, weapons, and structures that have shaped our world. Here is a brief overview of the development of metallurgy:

1. Early Metallurgy: The origins of metallurgy can be traced back to ancient times when humans discovered and began working with naturally occurring metals. The earliest known metalworking techniques date back to around 6000 BCE, with the discovery of copper in the Middle East. This period, known as the Copper Age or Chalcolithic period, marked the transition from the Stone Age to the Bronze Age.

2. Bronze Age: The Bronze Age, which began around 3000 BCE, was characterized by the widespread use of bronze, an alloy of copper and tin. Bronze was stronger and more durable than pure copper, making it ideal for tools, weapons, and armor. The development of bronze metallurgy revolutionized various aspects of human life, including agriculture, warfare, and trade.

3. Iron Age: The Iron Age, which followed the Bronze Age, saw the widespread adoption of iron as a primary metal for tools and weapons. Iron was more abundant and easier to extract than copper and tin, leading to its increased use. The Iron Age began at different times in different regions, with the earliest evidence of iron smelting dating back to around 1200 BCE in the Near East.

4. Industrial Revolution: The Industrial Revolution, which started in the 18th century, brought significant advancements in metallurgy. The discovery and development of new techniques, such as the Bessemer process and the open-hearth furnace, revolutionized the production of steel. Steel, an alloy of iron and carbon, became the dominant metal for construction, machinery, and transportation.

5. Modern Metallurgy: In the modern era, metallurgy has continued to advance with the development of new alloys, materials, and manufacturing processes. The use of advanced technologies, such as computer modeling and simulation, has enabled the design and production of materials with specific properties for various applications. Metallurgy plays a crucial role in industries such as aerospace, automotive, electronics, and construction.

6. Ongoing Research and Innovation: Metallurgy is a field of ongoing research and innovation. Scientists and engineers are constantly exploring new materials, refining existing processes, and developing sustainable and environmentally friendly practices. The focus is on improving the performance, durability, and efficiency of metals and alloys, as well as reducing their environmental impact.

Please note that the information provided above is a general overview of the development of metallurgy. For more specific information or detailed insights, it is recommended to refer to authoritative sources on the subject.
