The rolling mill is the production link that rolls steel ingots or billets into steel. The production of steel by rolling has the advantages of high productivity, a wide variety of products, strong continuity of the production process, and easy mechanization and automation. Therefore, it is more widely used than forging, extrusion, drawing and other processes. At present, about 90% of steel is rolled into products. Non-ferrous metal products are also mainly produced by rolling. The finished products of steel rolling are mainly divided into three categories according to the cross-sectional shape of the steel: steel plates, steel pipes and steel sections (including wire rods). Steel sections have the most cross-sectional shapes and varieties. According to their uses, they can be divided into commonly used steel sections (square steel, round steel, flat steel, angle steel, channel steel, I-beam, etc.) and special steel sections (rails, steel piles, bulb flat steel, window frame steel, etc.). According to the cross-sectional shape of the product, it can be divided into simple cross-sectional steel sections and special cross-sectional steel sections. The characteristic of a simple cross-sectional section is that the tangent line made at any point on the periphery of its cross-sectional section...
The principle of aluminum ingot casting is the physical process of cooling and crystallizing liquid aluminum into solid aluminum ingots through casting. The process flow is as follows: 1. Aluminum tapping: take the aluminum liquid out of the furnace; 2. Slag removal: remove impurities and slag from the aluminum liquid; 3. Weight inspection: weigh the aluminum liquid; 4. Batching: mix aluminum liquids of different components as needed; 5. Furnace loading: load the mixed aluminum liquid into the furnace; 6. Refining: refine the aluminum liquid to improve its purity and quality; 7. Casting: pour the refined aluminum liquid into the mold and wait for it to cool and solidify; 8. Aluminum ingots for remelting: inspect and weigh the cast aluminum ingots, and store qualified products; 9. Finished product inspection: check the appearance, size, weight and other indicators of the aluminum ingots; 10. Finished product weight inspection: weigh the aluminum ingots; 11. Storage: store qualified aluminum ingots in the warehouse. During the casting process, it is necessary to pay attention to controlling parameters such as temperature, time, and pressure to ensure the quality and performance of the aluminum ingot. At the same time, it is also necessary to pay attention to...
The technical parameters of aluminum melting furnaces usually include the following aspects: 1. Furnace capacity: This refers to the maximum volume of aluminum liquid that the furnace can accommodate. Common capacities include 1 ton, 2 tons, 5 tons, etc. For example, a 5-ton aluminum melting furnace is suitable for large-scale aluminum product manufacturers. 2. Heating power: Determines the speed and efficiency of furnace heating. Generally measured in kilowatts (kW), such as 300kW, 500kW, etc. The greater the power, the faster the heating speed is usually, but the energy consumption also increases accordingly. 3. Maximum operating temperature: Usually between 700-1000℃. For example, some models of aluminum melting furnaces have a maximum operating temperature of up to 900℃, which can meet the smelting needs of most aluminum and aluminum alloys. 4. Furnace lining materials: Common ones include refractory bricks, refractory castables, ceramic fibers, etc. Different furnace lining materials have different refractory and thermal insulation properties. 5. Energy consumption index: For example, the energy consumption per ton of aluminum, which is an important parameter to measure the energy-saving effect of the furnace. The energy consumption per ton of aluminum of an excellent aluminum melting furnace can be controlled at a low level. 6....
The melting point of aluminum is 660.37℃. In practical applications, the post-melting treatment methods of aluminum will vary depending on the specific situation. The following are some common treatment methods: Degassing and impurity removal: The aluminum liquid may contain gas and impurities, which will affect the quality of aluminum. In the later stage of melting, the gas and impurities in the aluminum liquid can be removed by using flux, stirring, blowing and other methods. Grain refinement: Sometimes it is necessary to refine the grains of aluminum to improve its mechanical properties. This can be achieved by adding grain refiners or using specific solidification processes. Alloying: If aluminum alloys need to be prepared, other alloying elements can be added in the later stage of melting to achieve the desired composition and properties. Temperature control: Accurately controlling the temperature of aluminum liquid is very important for subsequent processing and use. In the later stage of melting, the temperature needs to be adjusted according to specific requirements to ensure the quality and performance of aluminum liquid. Casting or molding: According to the requirements of...
What is the use of rolling mill? A rolling mill, also known as a steel mill, is a device that realizes the metal rolling process. It mainly uses two rotating rollers to extrude and deform metal materials to obtain materials of various shapes and sizes. Rolling is the most important production method in metal pressure processing, and rolling mills are also the main pressure processing equipment. The uses of rolling mills include: 1. Changing the shape and size of metal materials: Raw materials such as steel billets and aluminum ingots can be rolled into various plates, pipes, profiles (such as angle steel, channel steel, etc.) and wires, etc., to meet the requirements of different industrial fields for the shape and size of metal materials. 2. Improving the performance of metal materials: Through pressure processing during the rolling process, the grain structure inside the metal is refined, thereby improving the mechanical properties of the material such as strength, hardness, and toughness. 3. Improving production efficiency: It can achieve continuous and large-scale production, and has higher production efficiency than other processing methods. 4. Ensuring the consistency of product quality: Rolling under precisely controlled conditions helps to ensure the dimensional accuracy, surface quality...
Aluminum is a silvery-white light metal, relatively soft, with a density of 2.7 grams per cubic centimeter, a melting point of 660.4℃, and a boiling point of 2467℃. Under standard atmospheric pressure, the melting point of aluminum with a purity of 99.996% is generally recognized to be 660.24℃, and the melting point of aluminum with a purity of 99.99% is generally 1-2℃ lower. When the temperature reaches 660℃, aluminum begins to melt, and the temperature will continue to rise after it is completely melted if the temperature is continued to be heated. Above 660℃, aluminum metal is in liquid state; below 660℃, aluminum metal is usually in solid state. The post-treatment of aluminum after melting depends on the specific needs and application scenarios. The following are some common treatment methods: 1. Casting: Injecting liquid aluminum into a mold to manufacture various aluminum products, such as aluminum ingots, aluminum castings, etc.; 2. Refining: Further removing impurities and gases in the aluminum liquid to improve the quality of aluminum; 3. Alloying: Adding other metal elements to make aluminum alloys to improve the properties of aluminum, such as strength, hardness, corrosion resistance, etc.; 4. Surface treatment: Surface treatment of aluminum or aluminum alloy...
