What Is the Acromion Process?

The capped steel is forced to stop boiling and solidify as soon as possible by mechanical or chemical methods no later than 1 to 3 minutes after pouring, so that the head structure is improved, the concentration segregation is reduced, and the chemical uniformity of the ingot is also improved to a certain extent. Similar to boiling steel, it is a steel between boiling steel and semi-killed steel, also known as capped steel.

The capping steel is no later than 1 to 3 minutes after pouring, using mechanical or chemical methods to force the steel flakes to stop boiling and solidify as soon as possible, so that the head structure is improved, the concentration segregation is reduced, and the chemical uniformity of the ingot is also certain

Gland steel is divided into mechanical gland steel and chemical gland steel.

Generally suitable for the production of plates, strips, wires and profiles with a carbon content of more than 15%. It is especially suitable for the production of cold-formed and cold-head forged steel.

During the ingot casting process, a deoxidizing agent is added to control the boiling effect of the steel during the ingot casting. During the solidification of the steel, excessive gas will remain in the steel, causing the steel to expand in the ingot mold. The capping operation limits the gas release time and prevents the formation of excessive pores in the steel ingot ^[2] .
