Plates are designed by continuous rolling and casting or, in most instances, steel is processed into a bullet then hot rolled to be shaped in its final plate thickness. Akin to steel plates, rolled ring forgings are forged in the same process – it differs only in terms of rolling directions. Continue reading to know the difference between the two.
Process, Cost, and Strength of Forged Ring and Hot Rolled Plate
Manufacturing Process
In case you’re wondering, it takes continuous rolling and casting to produce plates. It’s also possible to forge steel into a billet before it is hot rolled until it attains the desired thickness of its final plate. Forged rings are a lot similar to steel plates because the rings go through a forging process from a billet of steel before these are rolled into their required shape. The key difference between both is that forged rings need to be rolled in two directions while rolling the plates only requires a single direction.
Cost
Hot rolled plate is a bit expensive than rolled ring forgings as the former results in more material scraps. Since rolled ring forgings are milled to a precise donut shape, there are no middle holes to be thrown out or corners to be clipped during the manufacturing process. It is not acquired as a square, solid plate but is already ready to use.
Strength and Difficulty
Despite being less expensive than hot rolled plates, rolled ring forgings possess the same strength and quality as that of the former. According to forge experts, these rings similar tensile strengths and yield as hot rolled plates.In terms of difficulty to wield, rolled ring forgings show no brittle or hard layer on its rings. For as long as the manufacturing complies with the standard and stringent consumer qualification processes, the rings are guaranteed to meet the mandatory specifications.
