Description

Technical Field

[0001] The utility model relates to the technical field of alloy bar casting and forming, in particular to a high-temperature alloy bar casting and forming device. Background Technique

[0002] High-temperature alloys refer to a class of metallic materials based on iron, nickel, and cobalt that can work for a long time under high temperatures above 600 degrees Celsius and certain stress conditions. They have excellent high-temperature strength, good oxidation and hot corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties, and are also known as "superalloys". There are mainly iron-based, nickel-based, and cobalt-based high-temperature alloys. High-temperature alloys are mainly used to manufacture high-temperature components such as turbine blades, guide vanes, turbine disks, high-pressure compressor disks, and combustion chambers of aeroengines, naval ships, and industrial gas turbines. They are also used to manufacture aerospace vehicles, rocket engines, nuclear reactors, petrochemical equipment, and energy conversion devices such as coal conversion.

[0003] In the production process of high-temperature alloy bars, the casting and forming process is very important. Casting and forming refers to the method and technology of pouring molten steel into steel ingots. According to the orientation of the molten steel entering the steel ingot mold, the method can be divided into top pouring and bottom pouring. The two most important process parameters in the casting process are the casting temperature and the casting speed, which determine the surface quality of the steel ingot. In the existing high-temperature alloy bar casting and forming equipment, when discharging materials, since the casting liquid solidifies in the vertically arranged casting cavity, the alloy bar cannot be conveniently taken out from the inside of the casting cavity, making the processing inconvenient. Moreover, after casting, the high-temperature alloy usually needs to go through a cooling and forming process. During the cooling process, the casting pipeline usually needs to be sealed. It is usually very difficult to work in a sealed state in a high-temperature environment, which greatly affects the forming efficiency of alloy bar casting. Content of the Utility Model
