How to choose high-quality titanium rods?
Titanium rod is a common titanium product and also a common raw material, but when we purchase it, how do we choose high-quality titanium rods? The following is an introduction to several aspects.
1. Due to severe wear of the rolling groove, the surface of titanium is uneven, and the appearance of low-quality titanium rods often has pits, spots, etc.
2. There are scratches on the surface of low-quality titanium materials due to the simple equipment of low-quality titanium manufacturers, which can easily produce burrs and scratch the appearance of titanium materials. Deep scratches can reduce the strength of titanium.
3. Poor quality titanium bars are thin and low, often showing dissatisfaction with their appearance. The reason is that the manufacturer, in order to achieve a high level of negative public service, puts a lot of pressure on the first few lines of the product, but the pressure on the titanium bars is small, which cannot meet the filling requirements.
4. Poor quality titanium rods are easy to fold. Creases are various creases formed on the surface of titanium rods, which often run through the longitudinal direction of the product. The reason for folding is that low-quality manufacturers have a low purchase rate, a large amount of pressure drop, and there are folding ears. When folding, there is rolling down, and the folded product will crack after bending, greatly reducing the strength of titanium.
5. Poor quality titanium rods are prone to scarring in appearance. The raw material of low-quality titanium rods is uneven and contains many impurities. Simple titanium glue equipment is prone to scarring after rolling.
6. Poor quality materials are prone to cracking in appearance due to the fact that the billet is adobe, which has many pores. During the cooling process, the adobe cracks due to thermal stress, and after rolling, cracks appear.
7. Poor quality titanium rods have no metallic luster and appear in a light red or pig iron like color. There are two reasons for this: the raw material is adobe. Unqualified materials were not rolled at standard temperatures, and the temperature of titanium was measured visually, making it impossible to roll in conventional austenitic areas and rendering titanium functionally unqualified.
8. The cross-section of the low-quality titanium rod is elliptical, and the pressure drop in the first two lines of the roller is relatively large. The strength of this titanium thread is greatly reduced and does not comply with the external dimension specifications of titanium threads.
