What does metallurgy mean, what does metallurgy mean

Refining metals out of ores.

Metallurgy is the process and process of extracting metals or metal compounds from ores and using various processing methods to make metal materials with certain properties.

A brief history, definition and classification of metallurgy.

30 4 billion years ago, the Earth was born in the vast universe. The universe is like a high-temperature smelting furnace that restores the metal direction.

The center gathers and sinks in the center of the earth to become the core (Fe, Ni metal melt), and then the surface of the metal forms a sulfide layer.

matte), and then form an oxide layer (slag) on the surface, and finally surround an atmospheric layer on the outer surface of the metal melt and slag.

equivalent to temperature, pressure, atmosphere), and thus the earth on which human beings depended was formed.

Then God created all things on earth and also created human beings. God is really too partial to human beings, and he is not only.

He gave mankind all kinds of materials to live on, and at the same time he taught mankind to think and use tools, so that human beings became.

The master who governs the fate of all things in the world (referring only to the earth).

Humans have long learned how to get the material they need from nature. From the Stone Age to the subsequent Bronze Age.

generation, and then to the large-scale development of modern steel smelting. The history of human development is integrated with the development of metallurgy.

With the successful application of physical chemistry in metallurgy, metallurgy has moved from technology to science, so there is metallurgical engineering in universities.

Specialized. Metallurgy is the process of extracting metals from metal ores, purifying and synthesizing metals, and making useful substances from metals.

Technology. Metallurgy can be divided into ferrous metallurgy (iron, chromium and manganese) + non-ferrous metallurgy (aluminum, copper, etc.) according to industry classification.

According to the discipline classification, it can be divided into: chemical metallurgy (also known as extraction metallurgy) + physical metallurgy.

Metallurgical Fundamentals: Chemistry (mainly physical chemistry) + Physics (three transmissions, solidification, rolling, etc.).

The metallurgical industry refers to the industrial sector of exploration, mining, selection, smelting, and rolling of metal minerals. It includes two categories: ferrous metallurgical industry (i.e., iron and steel industry) and non-ferrous metallurgical industry.

The metallurgical industry is an important raw material industry sector, which provides metal materials for all sectors of the national economy and is also the material basis for economic development.

In fact, the encyclopedia also has it.

Metallurgy is the process of extracting metal compounds from minerals by some means of processing. Metallurgical technology is mainly divided into electrometallurgy, hydrometallurgy and pyrometallurgy. Metallurgy was originally developed from copper smelting in pottery.

The metallurgical industry is mainly divided into ferrous metallurgy industry, non-ferrous metallurgy industry, rare metal metallurgy industry, and powder metallurgy industry. The ferrous metallurgy industry refers to the production of copper, iron, etc. Non-ferrous metallurgical industry refers to the processing and production of various metals.

In the smelting technology, pyrometallurgy is mainly a metallurgical process carried out under high temperature conditions. Including, drying, roasting, roasting, smelting, refining, distillation, etc.

Hydrometallurgy is mainly a metallurgical process carried out in solution. Including, leaching, purification, preparation of metals, etc. Electrometallurgy is mainly a method of extracting metals using electrical energy.

It is further divided into electrothermal metallurgy and electrometallurgy. Metallurgy is essentially the process of removing impurities to obtain pure compounds.

Metallurgical Overview:

Metallurgy, developed from ancient pottery. The first is copper smelting. The melting point of copper is relatively low, and with the development of pottery, the working temperature required for pottery is getting higher and higher to reach the melting point temperature of copper.

In the process of making pottery, pottery was made in some places where there were copper mines, and copper was naturally found to be attached to biomass. With the accumulation of experience, the ancients gradually mastered the smelting method of copper.

The meaning of smelting: (moving) to extract the metal from the ore by roasting, smelting, electrolysis and the use of chemicalsAffected by the war.

Pyrometallurgy

Pyrometallurgy is a metallurgical process that takes place at high temperatures. Some or all of the minerals in the ore or concentrate undergo a series of physical and chemical changes at high temperature to form another form of compound or elemental group defect, which is enriched in gas, liquid or solid products respectively, so as to achieve the purpose of separating the metal to be extracted from gangue and other impurities.

The heat energy required to realize the pyrometallurgical process is usually supplied by fuel combustion, and also depends on the chemical reaction in the process, for example, the oxidative roasting and smelting of sulfide ore do not need to be heated by fuel; The process of thermal reduction of metals is also carried out by self-heating. Pyrometallurgy includes: drying, roasting, roasting, smelting, refining, distillation and other processes.

Metallurgy has a long history of development, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting and tung smelting.

Metallurgical engineering is an applied discipline that studies the extraction of valuable metals or their compounds from ores and processes them into materials, and cultivates professionals in the field of metallurgical engineering in terms of scientific research and development and application, engineering design and implementation, technical research and technological transformation, new technology promotion and application, engineering planning and metallurgical enterprise management.

Introduction to the fieldThe field of metallurgical engineering is the field of engineering and technology that studies the extraction of metals or metal compounds from ores and other resources and the production of materials with good performance and economic value.

Metallurgy is the foundation of national economic construction, is a symbol of national strength and industrial development level, it provides materials and products for machinery, energy, chemical industry, transportation, construction, aerospace industry, national defense and military industry and other industries.
