Drawing titanium plate with hot rolled titanium tube as a material, after pickling to remove the oxide skin for cold rolling, the products for the rolled hard coil, due to continuous cold deformation caused by cold hardening of the rolled hard coil strength, hardness, toughness and plastic targets, and thus the stamping performance will deteriorate, can only be used for simple deformation of the parts.
Rolled hard coil can be used as hot-dip galvanizing plant material, because hot-dip galvanizing units are set up to retreat before. Rolled hard coil weight is usually 6 ~ 13.5 tons, titanium tube inner diameter of 610mm. usually cold rolled plate, coil should be through the successive annealing (CAPL unit) or hood furnace annealing to eliminate cold hardening and rolling stress, to reach the corresponding specification of the mechanical properties of the rules of the target.
Hot rolled titanium plate with continuous casting slab or initial rolling slab as a material, heated by the step heating furnace, high pressure water descaling into the roughing mill, roughing material by cutting the head, tail, and then into the finishing mill, the implementation of computer-controlled rolling, final rolling that is through the laminar flow cooling and coiling machine coiling, become a straight hair roll. The head and tail of the straight hair roll is often tongue and fishtail shape, thickness, width accuracy is poor, the edge of the wave often exists, folded edge, tower and other shortcomings. Its volume weight is heavy, titanium tube inner diameter is 760mm.(Usually tube making profession likes to use.) The straight hair roll by cutting head, tail, cutting edge and more than one straightening, flattening and other finishing line disposal, and then cut plate or re-roll, that is to become: hot rolled titanium plate, flat hot rolled titanium tube, longitudinal cut strip and other products.
