What are the ingot casting technologies of the ingot casting machine?

What are the ingot casting technologies of the ingot casting machine? Ingots are made by pouring molten metal into permanent or reusable molds. After solidification, these ingots (or bars, slabs or billets, depending on the container) are further machined into a variety of new shapes. Ingot casting includes a series of procedures from the steelmaking furnace tapping (or the end of the out-of-furnace refining) to the stripping of the ingot to the soaking furnace of the blooming mill, that is, preparation before pouring, pouring, demoulding, ingot finishing or hot delivery Wait. Ingots make up a large portion of the entire metal casting and are divided into 3 categories: static ingots, semi-continuous or direct-cooled ingots, and continuous ingots.

The ingot casting technology of the ingot casting machine is divided into the following three types:

 

1. Static ingot casting technology

 

Static ingot casting is simply pouring molten metal into a mold to solidify and then pulling the ingot out of the mold so that the mold can be reused.

 

2. Semi-continuous ingot casting technology

 

The semi-continuous ingot casting process is used to make most of the cast alloys in the aluminum industry, from which shapes such as bars, sheets, laths, plates, etc. are machined. During this process, molten aluminum is transferred into a water-cooled mold, and a movable base is attached to the mold's long piston. After further solidification of the mold surface to form a hard "skin", the piston moves down and more metal is continuously filled into the container. Then, the piston moves to its full length and the process stops. The conventional approach in the aluminum industry is to use properly lubricated metal molds. Process improvements, however, have allowed major aluminum alloy producers to replace (at least partially) metal molds with electromagnetic fields that allow the molten metal to contact the metal mold for short periods of time, so products with a higher finish can be produced than conventional methods.

 

3. Continuous ingot casting technology

 

Continuous ingot casting provides the main casting material resource for the steel and copper industries, and is developing rapidly in the aluminum industry. During this process, molten metal is fed into a mold, which is very similar to semi-continuous casting in the beginning. But the process does not stop after a certain period of time, and the solidified ingot is continuously cut or cut to a certain length and transported away during the casting process. Thus, the process is continuous and the solidified bar or slab is transported away as quickly as it is cast. This method has many economic advantages over traditional casting processes.
