Abstract
The invention relates to a manufacturing method of a large-caliber thick-walled titanium tube block. The manufacturing method is performed by the following steps that (1) a processed titanium cast ingot is put into a furnace and is heated to 950 to 1150 DEG C, and upsetting and swaging are performed on a free forging oil press according to a certain proportion; (2) the processed titanium cast ingot is put into the furnace again and is heated to 900 to 1050 DEG C, and punching is performed; (3) a mold is preheated, a lubricant is applied, a blank is heated to 920 to 1050 DEG C, and a V-shaped anvil is used for swaging according to a certain proportion; (4) the blank is put into the furnace and is heated, a swaging die is used for swaging, and simultaneously, molding and rolling are performed. According to the manufacturing method, only the punching process and the swaging process are controlled, so that titanium and titanium alloy thick-walled tubes are prevented from easily forming the defects of pits, wrinkles, microcracks and the like at the surfaces of the tube blocks due to repeated rolling in a traditional extrusion and rolling process. A variety of titanium tube blocks of large specifications can be manufactured, and the tube block yield is increased.
Description
One, technical field
The manufacture method that the present invention relates to a kind of heavy caliber titanium thick-wall tube, belongs to the materials processing of non-ferrous metal.
Two, background technology
Along with developing by leaps and bounds of National modern industry, modern chemical industry equipment and pressure vessel be on a large scale, large scale, and large-tonnage development, therefore more and more higher to the dimensions of tubing, particularly corrosion resisting property is had higher requirement.Titanium or titanium alloy tubing, because of advantages such as corrosion resistance are good, intensity is high, nonmagnetic, linear expansion coefficient is little, has been widely used in the pressure vessel on various device both at home and abroad.The titanium or titanium alloy size of pipe and tubing that common common pipe-line system is used is less, and the titanium pipe size of using on chemical industry equipment large (diameter is about 200～700mm), surface quality requires high.The factors such as heavy caliber titanium pipe work flow is long, loss large and internal surface of pipe quality is wayward, cause large chemical equipment extremely low by the yield rate of heavy caliber titanium thick-wall tube.
Traditional heavy caliber titanium pipe processing technique mainly contains three kinds of techniques:
Be a method that adopts rolling+heat to expand, first manufacture a pipe, the method enlarged diameter that reusable heat expands.Add man-hour tubing surfaces externally and internally and be all subject to force of rolling friction effect along rolling direction, in the operation of rolling, interlock has aggravated the sticking to mould degree between material and mould repeatedly, and repeatedly roll and easily cause tube surfaces to produce the defects such as pit, wrinkle,
Another kind is the method that adopts bar machine to add.It is high that machine adds expense, and raw material availability is low, and the performance of tubing is guaranteed by bar, for major diameter bar guaranteed performance, is a difficult problem.
The third V-type anvil pulling is the effective ways of forged steel cylindrical shell and thick-wall tube, and during pulling, tube surfaces is subject to the distortion of superficial layer three-dimensional compressive stress to be conducive to moulding.V-type anvil is applied for many years in iron and steel enterprise for the forging of cylindrical member.Surperficial tolerance dimension inside and outside this method is larger, with V-type anvil, comes the cylindrical member cost of forged titanium inevitable high.
Three, summary of the invention
The object of the invention is, for above-mentioned deficiency of the prior art, provides a kind of manufacture method of heavy caliber titanium thick-wall tube.
The technical solution used in the present invention is: adopt the pulling of hammer cogging+punching+reconditioning+V-type anvil pulling+tup; The present invention carries out according to the following steps:
(1), the titanium ingot casting processing is put into the temperature that stove is heated to 950--1150 ℃, temperature retention time 0.5--1 hour, on open die forging hydraulic press, then carries out jumping-up and pulling according to the ratio of 0.3---0.4;
(2), be reentered into the temperature heating that is heated to 900--1050 ℃ in stove, carry out punching;
(3), preheated mold 200--300 ℃, coat lubricant, blank heating to 900--1050 ℃, is pulled out; V-type anvil pulling anvil width ratio is between 0.5--1.0, and the internal diameter gap of the diameter of plug and tubing is 10--20mm;
(4), put into stove and be heated to after the temperature heating of 840--960 ℃, round as a ball with tup pulling; Apart from finished product length 400--500mm, stop forging, carry out strict reconditioning;
(5), finished product processing: heat the temperature of 840--960 ℃, round as a ball with tup pulling, finished product is annealed to excellent base after reaching dimensional requirement, selects 650---750 ℃, is incubated 2 hours.
The titanium pipe that this manufacture method is produced or the external diameter of titanium alloy pipe are 160mm～800mm, and wall thickness is 15---100 millimeter.
The present invention compared with prior art has the following advantages:
1, it is simple to operate that the present invention utilizes existing forging equipment, and process flow is short.
2, the bar of the present invention after conventional cogging is forged carries out punching, and the pulling of V-type anvil adds tup pulling, can make the wall thickness of tubing reach larger size (wall thickness reaches 15--100mm), improves surface quality and yield rate.
3, the relative pair rolling technique of the present invention reduces a series of production processes such as oil removing, pickling, reduces and pollutes.
