Continuous casting roll manufacturers to remind you must consider the oxidation of wire

Date: 2017-03-22

The wire must be considered for oxidation, in order to prevent the formation of plastic deformation is not uniform to avoid failure in the course of the operation

As the protective gas oxidation increases, the amount of deoxidized elements (such as silicon, manganese, titanium, etc.) in the wire increases correspondingly, and the strength of the weld metal is reduced. When the deoxidation element in the wire contains the most insufficient, causing the weld toughness to decline, but also may lead to welding defects (such as pores, etc.) generation.

Welding hot-rolled steel, normalizing steel and welding under the use of low-carbon quenched and tempered steel, the first consideration of the mechanical properties of the weld metal and the base metal close to or similar to the weld metal chemical composition and the parent material is put In the secondary. In the welding of some large thickness, large binding of the components to prevent the emergence of welding cold cracks, may consider the principle of low matching, that is, the use of weld strength slightly lower than the base metal strength of the wire. Experience has shown that if the weld strength exceeds the base metal too much, the joint cold bending, plastic deformation is not uniform, resulting in cold angle is small, or even cracks.

1 micron machining method. Precision machining is done under tightly controlled environmental conditions using precision machine tools and precision gauges and gauges. Processing accuracy to achieve and more than 0.1 micron ultra-precision machining. In the aerospace industry, precision machining is mainly used for machining precision mechanical parts in aircraft control equipment, such as precision fittings in hydraulic and pneumatic servos, gyroscope frames, housings, flotation, liquid-filled bearing assemblies and Floats and so on. The precision parts of the aircraft are complex, the rigidi...

The elongated shaft machining supplier tells you the advantages of the hollow shaft

2017 - 03 - 22

Hollow shaft is more and more people to use, then let's talk about what the advantages of what you loved by everyoneHollow shaft occupies a relatively large volume of space, but can reduce the weight. According to the mechanical analysis of materials, in the shaft transmission torque, from the radial section to see, the more the place outside the effective torque transmission effect. In the shaft need to pass a larger torque, you need a thick shaft diameter. And because the role of the torque in the axial parts of the smaller, so the general use of hollow to reduce the weight of the shaft.
