Titanium rods are a common titanium product and a common raw material, but when we buy them, how to choose a quality Titanium Rod? Here are a few aspects of the introduction.
1. Due to the unevenness of the titanium surface caused by the severe wear and tear of the rolling groove, the appearance of poor-quality titanium rods is often characterized by pockmarks, pockmarks and so on.
2. Inferior quality titanium has scratches on the surface, the reason is that the inferior titanium manufacturer's equipment is simple, easy to produce burrs, scratching the appearance of titanium, deep scratches will reduce the strength of titanium.
3, inferior Titanium Bar is thin and low, often showing dissatisfaction with the appearance, the reason is that manufacturers in order to achieve a large negative public service, the first few lines of the product pressure, titanium bar pressure is small, filling can not meet.
4, poor quality titanium rods are easily folded. Folding is a variety of creases constituted on the surface of the titanium rod, this defect often runs through the longitudinal direction of the product. The reason for folding is that the inferior manufacturers seek a low rate, the amount of pressure to fall is large, the appearance of folding ears, folding appears to roll down, after folding the product after bending will be cracked, the strength of titanium is greatly reduced.
5, the appearance of poor quality titanium rods are prone to scarring. Inferior quality titanium rods have uneven raw materials and many impurities. Simple titanium rubber equipment, easy to scar after rolling.
6, the appearance of poor quality material is prone to cracks, the reason is that its billet is adobe, there are many air holes in adobe, adobe in the cooling process due to thermal stress, cracks, cracks after rolling.
7, inferior titanium rods have no metallic luster, light red or similar to the color of pig iron, for two reasons two, its billet is adobe. Unqualified material is not rolled at the standard temperature, the temperature of titanium is measured visually, so that the conventional austenitic region can not be rolled, titanium function can not be qualified.
8, inferior titanium rods have an oval cross-section, and the pressure drop of the two lines in front of the roll is large. The strength of this titanium thread is greatly reduced, and does not meet the specification of the external dimensions of the titanium thread.
