British standard H-shaped steel

Welded H-shaped steel is a type of steel used in the construction of beams or columns in civil engineering. Welded H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving, and light structural weight in all directions, and has been commonly used. Below, I will introduce you to the rolling process of H-beam steel. The rolling process of H-beam steel, plate and strip steel, is very simple to understand, with only the left and right rollers rolling.

H-shaped steel, as its name suggests, is like an H letter. The English standard for H-shaped steel is how complex styles of steel are rolled and produced. This requires a special rolling technique called pass rolling.

How to roll the welded H-beam into a rough billet? The square billet is first rolled into an H-shaped shape using a two roll billet opening machine with a pass, and the section style is obtained after the square billet enters a relative pass position. The second and third holes from left to right are the same as the the first mock examination, and one of them is a spare hole during production.

The subsequent demand for precision rolling of rolling mills is to use a universal rolling mill to produce qualified welded H-beams. The universal rolling mill has never had two rolls on the left and right sides, but a total of four rolls on the left and right sides, with only one pass.
