Embodiment 1
[0027] Such as figure 1 Shown, this adopts the method for multi-pass rolling titanium alloy rod wire rod, and it comprises the following steps:
[0028] Step 1. Put the TC4 titanium alloy sheet with a size of 30mm×30mm×20mm into the heating furnace for two stages of preheating, specifically:
[0029] 1.1 Preheating Ⅰ: Preheating at 800°C for 10 minutes;
[0030] 1.2 Preheating II: Continue to preheat at a temperature of 900°C for 20 minutes;
[0031] Step 2. The preheated rolled material is subjected to three stages of four-stage heat preservation, rolling (the titanium alloy plate is rolled on a two-roll rolling mill) and annealing, specifically:
[0032] 2.1 Hold the temperature at 900°C for 5 minutes, and perform the first rolling pass. The first pass rolling is to take the longitudinal direction of the titanium alloy plate as the rolling direction, and perform annealing treatment at a temperature of 900°C for 10 minutes;
[0033] 2.2 Continue to hold the temperature at ...
Embodiment 2
[0039] Such as figure 1 Shown, this adopts the method for multi-pass rolling titanium alloy rod wire rod, and it comprises the following steps:
[0040] Step 1. Put the TC4 titanium alloy sheet with a size of 32mm×32mm×22mm into the heating furnace for two stages of preheating, specifically:
[0041] 1.1 Preheating Ⅰ: Preheating at a temperature of 820°C for 14 minutes;
[0042] 1.2 Preheating II: Continue to preheat at a temperature of 920°C for 24 minutes;
[0043] Step 2. The preheated rolled material is subjected to three stages of four-stage heat preservation, rolling (the titanium alloy plate is rolled on a two-roll rolling mill) and annealing, specifically:
[0044] 2.1 Hold the temperature at 920°C for 7 minutes, and perform the first rolling pass. The first pass rolling is to take the longitudinal direction of the titanium alloy plate as the rolling direction, and perform annealing treatment at a temperature of 920°C for 14 minutes;
[0045] 2.2 Continue to hold th...
Embodiment 3
[0051] Such as figure 1 Shown, this adopts the method for multi-pass rolling titanium alloy rod wire rod, and it comprises the following steps:
[0052]Step 1. Put the TC4 titanium alloy plate with a size of 35mm×35mm×25mm into the heating furnace for two stages of preheating, specifically:
[0053] 1.1 Preheating Ⅰ: Preheating at 850°C for 20 minutes;
[0054] 1.2 Preheating II: Continue to preheat at 950°C for 30 minutes;
[0055] Step 2. The preheated rolled material is subjected to three stages of four-stage heat preservation, rolling (the titanium alloy plate is rolled on a two-roll rolling mill) and annealing, specifically:
[0056] 2.1 Hold the temperature at 950°C for 10 minutes, and perform the first rolling pass. The first pass rolling is to take the length direction of the titanium alloy plate as the rolling direction, and perform annealing treatment at a temperature of 950°C for 20 minutes;
[0057] 2.2 Continue to hold the temperature at 1050°C for 10 minutes, ...
