Embodiment Construction
[0010] A hot extrusion process method for super-long TC11 titanium alloy pipe products, the first step of the method is to cut off the riser and ingot bottom of the TC11 titanium alloy ingot, and remove the surface defects of the TC11 titanium alloy ingot; at the same time, TC11 The cross-section of the titanium alloy ingot is a circle with a diameter of 480 mm to 630 mm. The second step: use a forging press to carry out blank forging on the TC11 titanium alloy ingot after removing surface defects in the first step, and perform surface grinding treatment after air cooling to obtain a primary forging blank; at the same time, the blank forging uses The forging method of axial elongation is divided into one fire, and the initial forging temperature of each fire is 100°C-150°C above the β transformation point; in addition, the cross-section of the primary forging billet is the side length 220mm ~ 230mm round bar, TC11 titanium alloy large size bar with a length of 2500mm ~ 3500mm....

Abstract
The invention discloses a hot extrusion process method of an ultra-long TC11 titanium alloy pipe product. The method comprises the following steps: (1) cutting a feed head and an ingot bottom of a TC11 titanium alloy pipe cast ingot, and removing surface defects of the TC11 titanium alloy pipe cast ingot; (2) carrying out cogging and forging on the TC11 titanium alloy pipe cast ingot by utilizing a forging press machine after the surface defects are removed in the step (1), and sequentially carrying out air cooling and surface polishing on the TC11 titanium alloy pipe cast ingot, so as to obtain a primary forging stock. The method has the beneficial effects that the process controllability of ultra-long TC11 titanium alloy pipe products is enhanced, the tissue shapes of the products are uniform, and the material yield is high; meanwhile, weld joints among the pipes are reduced in the actual use process, so that the use stability of the products is guaranteed, and the method is suitable for large-scale industrial production and high in production efficiency.
Description
technical field [0001] The invention relates to a hot extrusion process method for an ultra-long TC11 titanium alloy pipe product, in particular to a hot extrusion process method for an ultra-long TC11 titanium alloy pipe product for seabed oil. Background technique [0002] At present, most of the ultra-long TC11 titanium alloy pipe products for subsea oil on the market are produced and processed by welding process; the process is poor in operability, the product structure is uneven, and the scrap rate is high. In actual use, the product is stable. Poor performance; while large-scale industrial production, production efficiency is low. Contents of the invention [0003] Aiming at the shortcomings of the processing technology of the existing ultra-long TC11 titanium alloy pipe product for seabed oil, the invention provides a novel hot extrusion process method for the ultra-long TC11 titanium alloy pipe product. [0004] In order to achieve the above object, the measures t...
