Problems solved by technology

[0002] At present, the real production of U-profiles in China is still blank. The alternative production method is mainly to machine them on square materials that meet the side length size. The result of such processing is that the metal streamlines disappear, and the utilization rate of materials is very low. , less than 50%. At the same time, the processing volume is large, the cost is high, and the metal texture line is cut off during the processing process, which cannot meet the high-strength requirements
Therefore, this method is difficult to mass-produce profiles

Embodiment 1

[0028] A method for producing a titanium alloy U-shaped bar, comprising the steps of:

[0029] 1. The raw material is titanium alloy round bar blank of grade TA15, Φ90mm×1100mm.

[0030] 2. After the bar is heated to 980° C. with a box-type resistance furnace, it is rolled into a square bar of 48 × 48 × 3000 mm with a 430 horizontal open-end rolling mill.

[0031] 3. After flaw detection with an ultrasonic flaw detector, saw and cut into 1000mm long material sections, and use a portable grinder to grind the surface so that there are no cracks or defects on the surface.

[0032] 4. Then heat it up to 960°C with a box-type resistance furnace, keep it warm for 1 hour, and send it to the first two stands of the Φ280 horizontal open-end rolling mill equipped with a plate-type position guide device. The rolling speed is 1m per second, and 6 passes are carried out in sequence Rolling, design the dies for the 6-pass rolling passes in turn, and the 6-pass rolling passes are 3-K11—3-K6...

Abstract

The invention discloses a method for manufacturing a titanium alloy U-shaped material, and belongs to the field of metal processing technologies. The method includes steps of 1, manufacturing titanium alloy round rod from a blank; 2, heating and rolling the round rod by a box-type resistance furnace to obtain a square rod; 3, detecting flaws of the square rod by an ultrasonic flaw detector and polishing the surface of the square rod by a portable grinding machine; 4, rolling the square rod; 5, repairing the surface of the square rod; 6, stretching and straightening the square rod by a tension straightening machine; 7, washing the surface of the square rod by alkaline and acid; 8, detecting flaws of the square rod again by an ultrasonic flaw detector. The method has the advantages that the titanium alloy U-shaped material rolled by the method is high in precision, strength, quality and surface smoothness; requirements on all performance indexes of aviation sectional materials can be met by the rolled U-shaped material; a process for manufacturing the titanium alloy U-shaped material is simple and controllable, the yield can be increased by 35% at least, the material utilization rate can reach about 60%, the product cost can be lowered, and important conditions of batch manufacturing can be met.
