How to break steel bars quickly

There are many ways, such as: high temperature flame cutting, cutting machine cutting, hand saw cutting, steel bar cutting machine cutting, acetylene oxygen cutting.

The method of breaking steel bars is generally realized through physical reaction. Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel. The design of flame cutting torch provides sufficient oxygen for burning iron oxide and ensures good cutting effect.

Classification of flame cutting:

1, flame cutting:

Cutting torch is also called flame gun. The gas used is different and the structure is different. Oxygen-acetylene flame guns are usually used. Acetylene pressure is 0.0 1 ~ 0. 12 MPa, and oxygen pressure is 0.50 ~ 1.0 MPa. The two gases are mixed and burned in the flame gun through their respective channels, and the size and properties of the sprayed flame can be adjusted by holding the flame gun by hand for cutting, which is usually used for cutting rolled large-scale pipe blanks and slabs or straightening steel for supplementary cutting to eliminate defects.

2, cutting machine cutting:

It consists of a cutting torch whose working principle is similar to that of a flame gun, a fixed length mechanism and a slit cleaning device. There are mechanical, pulse and photoelectric length-fixing mechanisms, which can realize automatic length-fixing. The slit cleaning device is specially used to clean the residue adhered to the slit to avoid affecting the surface quality of steel during rolling.
