Method of identifying fake and inferior products with titanium rods
(1) Simple scratches of fake and inferior titanium rods are attributed to poor equipment of fake and inferior titanium rod manufacturers, which are prone to burrs and scratches on the appearance of titanium materials. Deep scratch reduces the strength of titanium.
(2) The appearance of fake and inferior materials is prone to cracks, because its billet is adobe, and there are many holes in the adobe. Because of the effect of thermal stress, cracks occur in the process of cooling, and cracks occur after rolling.
(3) The transverse bars of fake and inferior titanium rods are thin and low, often showing the appearance of full dissatisfaction. The reason is that the manufacturer in order to reach a large negative service, the reduction of the first several passes of the products is too large, the iron shape is too small, and the pass is not satisfied.
(4) The appearance of fake and inferior titanium rods often has the appearance of hemp. The flax surface is due to the irregular surface of titanium due to the severe wear of the rolling groove. Because fake and inferior titanium rod manufacturers want to seek profits, often show that rolling groove rolling is the most overexpenditure.
(5) Scar easily occurs on the surface of fake and inferior titanium rods. There are two reasons: (1) The raw materials of fake and inferior titanium rods are not uniform and there are many impurities. (2) The guide equipment of fake and inferior material manufacturers is simple and sticky to titanium. These impurities bite the roll and are prone to scarring.
(6) The cross-section of the fake and inferior titanium rods is elliptical. The reason is that in order to save data, the reduction of the front two rolls of the products is too large. The strength of the threaded titanium decreases greatly, and it does not conform to the specification of the shape and size of the threaded titanium.
(7) The fake and inferior titanium rods have no metallic luster and are light red or similar to pig iron. There are two reasons. Its billet is adobe. The rolling temperature of fake and inferior materials is not standardized, and their titanium temperature is visually measured, so that they can not be rolled according to the regular austenite region, and the function of titanium materials can not be qualified naturally.
(8) Fake and inferior titanium rods are easy to fold. Folding is a kind of broken line formed by the appearance of titanium rod, which often runs through the longitudinal of the whole product. The reason for folding is that fake and inferior manufacturers seek high efficiency, large reduction, ears occur, folding occurs in the next rolling, folded products will crack after bending, and the strength of titanium material is greatly reduced.
