Luoyang HongtengIntermediate frequency induction furnace
Our aluminum melting furnace has many advantages, as follows: 1. Fast heating speed: – The principle of medium frequency furnace induction heating is electromagnetic induction. The heat is generated by the workpiece itself, and the heating speed is fast. It can make the aluminum material reach the melting temperature in a short time, improving production efficiency. – For example, compared with traditional resistance furnaces, induction furnaces can greatly shorten the melting time of aluminum materials. 2. Less oxidation and decarburization: – There is very little oxidation during the heating process, and the metal burn loss is low. Generally speaking, the oxidation burn loss of aluminum is only about 0.5%, even if the raw material is broken, it does not exceed 1%, and for scrap aluminum, it is only 5% at most, which can effectively reduce material waste and reduce costs. – This makes the smelted aluminum liquid high in purity and good in quality, which is conducive to subsequent processing and product performance. 3. Uniform heating: – It can make the aluminum material evenly heated, with a small temperature difference between the core and the surface, ensuring the stability and consistency of product quality. – Through the precise temperature control...
Anti-corrosion media erosion can effectively block the erosion of external chemicals, such as acid and alkali components in the soil, moisture and salt in a humid environment, on the pipeline. Large-diameter pipelines have a large surface area and a wide range of contact with corrosive media. Good anti-corrosion measures can comprehensively protect the pipeline from erosion by these media from all parts. Pipelines will be physically damaged during transportation, installation and use, such as scratches and collisions. The anti-corrosion layer can serve as a buffer to reduce the direct damage caused by these physical factors to the pipeline body. For large-diameter pipelines such as 4.8 meters, more complex operating environments may be faced during installation, and the protective role of the anti-corrosion layer is particularly important. Effectively preventing corrosion can greatly extend the service life of the pipeline. For large-diameter pipeline projects, the laying and replacement costs of pipelines are high. Anti-corrosion measures are used to ensure the long-term and stable operation of pipelines, which can reduce the need for frequent replacement of pipelines due to pipeline corrosion, thereby reducing the overall project cost. Pipelines with anti-corrosion layers require relatively little maintenance during use. There is no need to frequently...
There are several main reasons for adding salt when melting aluminum: I. Covering and protection 1. Preventing oxidation: Salt forms a covering layer on the surface of aluminum liquid, which can effectively block air and reduce the contact between aluminum liquid and oxygen in the air, thereby reducing the degree of oxidation of aluminum liquid and preventing the formation of aluminum oxide. 2. Reducing burnout: Reduce the loss of aluminum liquid caused by oxidation and improve the recovery rate of aluminum. II. Refining effect 1. Adsorbing impurities: Salt can adsorb some impurities in aluminum liquid, such as oxides and hydrogen, which plays a role in refining aluminum liquid and improving the purity of aluminum. 2. Promoting impurity floating: Make impurities easier to gather and float to the surface of aluminum liquid, making it easier to remove. When does aluminum begin to melt? The melting point of aluminum is 660℃. When aluminum is heated to 660℃, it begins to melt. The actual melting situation is also affected by factors such as the heating environment and the purity of aluminum. If the heating rate is slow, it may start to melt at a temperature close to 660°C; if the purity is low...
What are the common methods for steel pipe anti-corrosion? Anti-corrosion methods 1. Coating anti-corrosion: – Use coating to form a protective film on the surface of the steel pipe to prevent the corrosive medium from contacting the steel pipe. Commonly used coatings include epoxy coatings, polyurethane coatings, etc. – This method is easy to construct and relatively low in cost, and is suitable for steel pipe anti-corrosion under various environmental conditions. 2. Cathodic protection: – By applying cathodic current to the steel pipe, the steel pipe becomes the cathode, thereby inhibiting the occurrence of corrosion. – Cathodic protection is usually used in combination with coating anti-corrosion, which can effectively improve the anti-corrosion performance of the steel pipe. 3. Corrosion inhibitor anti-corrosion: – Add corrosion inhibitors to the transported medium to slow down the corrosion rate of the steel pipe. – The selection of corrosion inhibitors needs to be based on the properties of the transported medium and the conditions of use. What are the uses of steel pipe anti-corrosion? Steel pipe anti-corrosion is crucial to ensure the safe and reliable operation of the project. In industries such as petroleum, chemical, and natural gas, the anti-corrosion performance of steel pipes is...
Steel pipe anti-corrosion is a series of measures taken to prevent steel pipes from being corroded during use. If steel pipes are not treated with anti-corrosion, they are prone to corrosion. Corrosion will make the wall thickness of steel pipes thinner, reduce their strength and bearing capacity, and may cause problems such as rupture and leakage during use of steel pipes, affecting their normal use functions. For example, in pipelines that transport media such as oil and gas, once the steel pipe is corroded and perforated, it will not only cause medium leakage, but also may cause safety accidents and environmental pollution. Steel pipe anti-corrosion is a technology or process designed to prevent or slow down the chemical or electrochemical reactions caused by environmental factors and the influence of the conveying medium during the use and transportation of steel pipes, which leads to corrosion. This technology is of great significance for extending the service life of steel pipes, reducing operating costs and ensuring the safety of conveying media. Overview of steel pipe anti-corrosion Definition: Steel pipe anti-corrosion is the process of surface treatment or coating of steel pipes by specific methods or materials to enhance their corrosion resistance....
The fundamental difference between melting and smelting is that melting is a process in which the state of a substance is changed from solid to liquid by heating it, while smelting is a process of obtaining pure metal from its ore by heating it to a higher temperature. In this article, we will explore all excerpt … The fundamental difference between melting and smelting is that melting is a process in which the state of a substance is changed from solid to liquid by heating it, while smelting is a process of obtaining pure metal from its ore by heating it to a higher temperature. In this article, we will explore all excerpt … What is Melting? The process of changing the solid state of a substance into its liquid state by the application of heat is called . Hence, in the melting process, a substance is heated to a temperature above its melting point, so that it can change its phase from solid to liquid. When the heat energy is provided to a substance, it breaks the chemical bonds that hold the molecules of the substance together in the solid phase, resulting to change the state into the liquid...
