Product details
Titanium alloy is a new type of metal structure material developed after the 1840s. Its main features are low density, high strength, especially high specific strength (strength/density), and good heat resistance and corrosion resistance, so titanium alloy is firstly applied in the aviation industry, and at the same time, the aviation industry is the main use sector of titanium alloy. Because of the excellent corrosion resistance of titanium alloy, it is also strongly used in the pump body and pipeline in the chemical industry, construction, sports and leisure, food, pharmaceuticals, biomaterials, energy, marine and automobile, and with the gradual reduction of the cost of titanium alloy, it will be even more widely used in the civil field.
Physical properties and classification of titanium alloy
Pure titanium is a silver-gray metal with good plasticity and hot and cold forming properties, low strength, and can be alloyed to obtain alloys with desired properties. Pure titanium melting point 1668 ℃, density 4.54 g/cm3, pure titanium at 882.5 ℃ when the isotropic isocrystalline transformation. At 882.5 ℃ for the dense row of hexagonal lattice, known as α-Ti; 882.5 ℃ above the body-centered cubic lattice, known as β-Ti, β-Ti heat resistance is poor, but the process of plasticity is good, easy to forge. Titanium and titanium alloys have poor thermal conductivity, high chemical activity, and are very sensitive to hydrogen, oxygen and nitrogen that cause their brittleness, which brings a lot of difficulties in smelting, machining, heat treatment, and results in higher production costs.
According to the classification of the phase composition of the annealed state, titanium alloys can be classified
into three main categories: α-type, α+β-type and β-type titanium alloys. The α+β type can also be further subdivided into
titanium alloys can be further subdivided into three categories: nearly α-type, α+β-type and nearly β-type.
Characteristics of forming process
(1) Conventional forging square process.
The advantage of conventional forging square process is that the forging method is more mature, the disadvantage is that the three sides are repeatedly turned over, the thickness is thin, the upsetting is easy to bend, the size of the three directions is not easy to control, and it is difficult to control the metal flow.
(2) Forging and elongation process.
Due to the small cross-section size of titanium ingot (about φ450 mm or so), can't use the method of pulling material directly forging out the cross-section size of the drawing, must first take the upsetting method, increase the cross-section area, for the subsequent widening to do the pavement. The biggest advantage of the forging and drawing process method is that the metal flow is regular, the width and thickness dimensions are easy to control, and the length is not limited. The process route is as follows: first widen, ensure a certain thickness, stand up and upsetting; then widen, upsetting, forging 4 corners; leveling; stand up and press the edge; turn 90 ° flat thickness; turn 90 ° again and press the edge; leveling, finished product. Forging and elongation process program
The specific forging process of the forging and drawing process program is as follows:
(1) First flatten the billet, then upsetting to increase the cross-sectional area. The blank is first flattened to a thickness of 250 mm and a width of about 600 mm, and then upsets it to increase the cross-sectional area, and at the same time forges 4 corners as far as possible, with a press-down amount of 200 mm, and then upsets it by turning it over by 180°, with a press-down amount of 200 mm, that is to say, the total press-down amount of the sequence is about 400 mm, and the dimensions of the blank are as follows: a height of about 1,700 mm, a width of about 700 mm, and a thickness of about 280 mm, and a thickness of about 1,500 mm, and a thickness of about 2,000 mm. See Fig. 1&2
(2) Flatten the blank, then use the upper flat anvil and the lower platform for flattening operation, spread as wide as possible, control the thickness of 170 mm, the maximum width of 1020 mm, the length of about 1050 mm. stand up upsetting, the main goal is to regularize the 4 corners, the amount of undercutting is about 50 mm. flip 180 ° and then upsetting, the amount of undercutting is about 50 mm. see figure 3
(3) Standing up to press the edge. Since the width is widened to 1020~1050 mm, there is enough margin for pressing the edge. The main purpose is to allow the excess material to extend as far as possible along the length while raising the edge.
The main purpose is to allow the excess material to extend as far as possible along the length while forming the edge. After the first press, turn the press 180° and press again to control the width dimension of 900 mm,
(4) Flat spreading length. Because of the thickness size increases to about 200 mm due to the front press edge upsetting, then the length must be extended by the method of pulling out without excessive widening, and the feeding volume must be controlled, the feeding volume cannot be too big, it is controlled at about 300 mm, and it is pressed one time after forging and then turned over 180° and pressed again one time.
(5) Standing up upsetting and leveling the two end surfaces, upsetting can be divided into 2 times forging, also can be divided into 3~4 times forging, trimming the forging, and finally complete the finished product.
