Description

technical field [0001] The invention relates to a smelting system, in particular to a metal smelting system. Background technique [0002] In the metal regeneration smelting ingot casting system, the shape and structural composition of the metal smelting furnace not only directly affect the operating efficiency of the smelting system, fuel consumption, etc., such as the material fluidity of the metal smelting furnace, the uniformity of furnace chamber pressure and temperature, etc.; Moreover, it also directly affects the operation of the smelting process, such as maintenance and slag removal of metal smelting furnaces, etc. This is more obvious for a single furnace or a multi-furnace combination with an unreasonable structure.

AI Technical Summary

Problems solved by technology

Such as the existing metal smelting furnace due to the shape and structure of the furnace body cavity, such as the shape of the bottom wall is a reverse trapezoid, which is not only inconvenient to clean the slag, but also takes a long time, and it is laborious and difficult to clean the slag. clean, affect production efficiency

Moreover, due to its internal and external structure, the slag removal process also affects the surrounding environment. The metal smelting slag falls all over the ground, and it still burns people, and even punctures the slag-carrying tires.

In addition, due to the high temperature and particularity of metal smelting, it is not easy to install a discharge part with adjustable height. Reasonable, and there is a contradiction between the discharge of the smelting liquid and the immersion elevation and the slag cleaning of the furnace chamber, which cannot be coordinated with each other

Either it is inconvenient to remove slag, or the height of metal immersion is limited, which affects the effect of immersion smelting, increases energy consumption and reduces production efficiency

[0003] In the smelting and ingot casting system, ring-shaped ingot casting machines are usually used for casting ingots, but the structure of this kind of ingot casting machine is not reasonable, such as the connection structure and corresponding shape of the casting molds. Moreover, the connection is unreliable, prone to loosening, affecting normal production, and even causing safety production accidents due to connection problems during operation.

[0004] In addition, ingot cooling is a basic process of smelting ingots. There are usually two ways for traditional ingot cooling. One is to directly input cooling water into the cooling holes inside the mold to achieve rapid cooling of the castings in the mold. Cooling device and corresponding cooling method Because the cooling speed of the ingot is fast and the cooling is uneven, it is easy to cause serious deformation of the ingot during the cooling process. When the cast ingot parts have a certain precision, the degree of deformation is more affected. At the same time, the cooling water is in direct contact with the casting, which reduces the surface quality of the ingot, which makes the quenching property of the casting, and when ingot a certain metal such as aluminum, the casting will turn black and discolored, etc., resulting in poor quality of the ingot casting

Another way is to spray water for cooling, which also has the problem of uneven cooling and poor cooling effect. At the same time, this cooling device and corresponding cooling method will generate a large amount of water vapor, which will affect the production site and the surrounding production environment. , and the water mist generated by it may also affect the sight of the on-site operators, so that undue operational safety accidents may occur due to improper operation of the operators; and another problem with this cooling method is that it is the same as the first method , which will make certain ingot products black and discolored, affecting the quality of casting products
