Cold rolled seamless titanium plate and hot rolled seamless titanium tube process
Jul 23, 2018


The titanium plate is made of hot-rolled titanium tube, which is acid-washed to remove the scale and then cold-rolled. The product is rolled hard. The cold work hardening caused by successive cold deformation makes the strength and hardness of the rolled hard roll rise and toughen. The target is reduced, so the punching performance will deteriorate and can only be used for parts that are simply deformed. The rolled hard roll can be used as a material for the hot-dip galvanizing plant, since the hot-dip galvanizing unit is provided with a retreating front. The hard roll weight is usually between 6 and 13.5 tons, and the inner diameter of the titanium tube is 610 mm. Generally, the cold rolled strip and coil should be eliminated by continuous annealing (CAPL unit) or hood furnace annealing to eliminate the cold work hardening and rolling stress, and reach the mechanical performance target of the corresponding specification.

The surface quality, appearance and dimensional accuracy of the cold-rolled titanium sheet are superior to those of the hot-rolled sheet, and the thickness of the product is thinly rolled to about 0.18 mm, which is favored by a wide range of users. The cold-rolled titanium tube is used as a substrate for deep processing of the product, which becomes a high value-added product. Such as electro-galvanizing, hot-dip galvanizing, fingerprint-resistant electro-galvanizing, color-coated titanium coils and vibration-reducing composite titanium sheets, PVC-coated titanium sheets, etc., so that these products have excellent quality, high corrosion resistance and other excellent quality, and have been widely used. After the cold-rolled titanium tube is annealed, it is necessary to carry out finishing, including cutting, tailing, trimming, leveling, flattening, rewinding, or longitudinal shearing. Cold-rolled products are widely used in automobile production, home appliance products, exterior switches, construction, work and furniture. After the titanium plate is bundled, the weight per package is 3 to 5 tons. The flat split weight is usually 3~10 tons/vol. The inner diameter of the titanium tube is 610 mm.

The hot-rolled titanium plate is made of continuous casting slab or slab slab as a material, heated by a step-type heating furnace, descaled by high-pressure water, and then enters the roughing mill. The rough-rolled material passes through the cutting head and the tail, and then enters the finishing mill to execute the computer. The rolling is controlled, and after the final rolling, it is taken up by a laminar cooling and a coiler to become a straight hair roll. The head and tail of the straight hair roll are often in the shape of a tongue and a fishtail. The thickness and width are inferior in accuracy, and the side has frequent shortcomings such as a wave shape, a folded edge, and a tower shape. The weight of the coil is heavier and the inner diameter of the titanium tube is 760 mm. (usually, the pipe occupation profession likes to use it.) After the straight hair is wound through the cutting, cutting, trimming and multi-pass straightening, flat and other finishing lines, and then cutting or rewinding, it becomes: hot rolling Titanium plate, flat hot rolled titanium tube, slitting tape and other products. If the hot-rolled finishing rolls are pickled to remove the scale and oiled, the hot-rolled pickled rolls are formed.
