Description

Technical Field

[0001] The invention relates to the technical field of metallurgical pouring, and in particular to a metallurgical pouring device. Background Art

[0002] Metallurgical pouring refers to the process of pouring molten metal through a mold or other equipment, usually used in casting processes to manufacture various metal parts and products. This process is crucial in metallurgical engineering and involves multiple steps and techniques.

[0003] The basic process of metallurgical pouring usually includes the following steps:

[0004] Melting: Heating the raw metal to above its melting point to turn it into a molten state. Melting is usually carried out in a blast furnace, induction furnace or electric furnace. Pouring: The molten metal is poured into a pre-prepared mold through a sprue or pouring pipe. During this process, the liquid metal fills the voids in the mold and forms the desired shape. Solidification: The molten metal cools and solidifies in the mold to form a solid metal part. Temperature control and timing of the solidification process are very important to the quality of the final product. Removal: After the metal is completely solidified, the mold is opened and the casting is removed for subsequent processing or inspection.

[0005] Metallurgical infusion is an indispensable part of modern manufacturing, involving multiple technical and process links. With the advancement of technology and changes in market demand, metallurgical infusion will continue to develop, ushering in higher efficiency and better product quality.

[0006] In the prior art, when pouring molten metal, splashing may occur due to height difference, bubbles or collision. The metal splashing may cause eye or skin injuries to the operator. The splashing molten metal may cause direct loss of materials, resulting in an increase in the overall production cost. At the same time, the splashing phenomenon may cause uneven flow of the molten metal, thereby affecting the filling quality of the casting.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. During metallurgical pouring, use an adjustable pouring pipe to pour the metal liquid at a uniform speed from the bottom of the mold. Pouring the metal liquid from the bottom can reduce the turbulence of the liquid flow, avoid sudden liquid impact, and thus avoid splashing. Pouring from the bottom of the mold can effectively reduce the chance of air entering the metal liquid and avoid splashing caused by the interaction between air and liquid. The protective cover can be set to protect against splashing, and at the same time, prevent external dust, debris and other contaminants from entering the mold, ensuring the cleanliness of the pouring process, thereby improving the quality of the casting. At the same time, covering the mold mouth can effectively control the gas entering the casting, reduce the risk of gas inclusion, and thus improve the physical and mechanical properties of the casting;

[0020] 2. Before metallurgical pouring, by setting up a moving mechanism and a mold handling mechanism, the mold handling mechanism can be driven by the moving mechanism to move into the mold before metallurgical pouring. Driven by the moving mechanism, the U-shaped brush and the moving brush can clean the inner wall of the mold, which can effectively remove the metal residue, sand and oxides left by the previous pouring, avoid contamination of the new casting, and thus improve the quality of the casting;

[0021] 3. By setting up the air duct, the mold processing mechanism can clean the inner wall of the mold while driving the fan blades to rotate, and inject the external air into the mold after filtering through the filter cartridge. At this time, the mold processing mechanism can blow the impurities brushed off out of the mold to ensure the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
