Application of titanium in transplantation

Because titanium alloy has the characteristics of high deformation resistance and poor plasticity, it is very difficult to use conventional plastic processing technology. For example, in the production of titanium alloy rods and titanium wires, due to their large variety and low output, it is difficult to organize the production with the continuous rolling of small bar and high-speed wire rod mills used in modern steel production. Due to the particularity of titanium alloy rod and titanium wire processing, compared with ordinary metals under the same conditions, its deformation resistance is high, widening is easy to be ears, the temperature range suitable for processing is narrow, and it is difficult to bite, so it adopts backward rows. In the production of high-speed rolling mills, it is difficult to guarantee the product quality in terms of product size or organization performance.

This production line implements low-temperature controlled rolling. Because the rolling temperature range of titanium alloys is narrow, the entire line is controlled by cooling the rolling piece and controlling the rolling speed. According to the rolling temperature range of the rolling piece, you can choose to perform water cooling or not. Perform water cooling. The production line adopts a special cooling system to control the temperature of the rolls and rolling pieces, and the closed-loop control is performed uniformly by the console, thereby ensuring the stability of the process and the quality of the rolled products. According to different steel grades, diameters and rolling speeds of the products produced, the console selects different cooling parameters, and adjusts the cooling temperature of the rolls and rolling pieces by adjusting the water volume.

At present, due to the backward processing methods, high-quality titanium alloy rods and titanium wires are scarce. Imports are mainly used to meet the domestic demand for high-quality titanium alloy rods and titanium wires. Therefore, it is of practical significance to establish a titanium alloy rod and titanium wire production line, and to introduce advanced new technology into the titanium alloy rod and titanium wire production line. It can meet the needs of materials such as titanium alloy rods, titanium wires and other materials in the fields of national defense, aerospace, and automobiles. Compared with conventional titanium wire and titanium bar rolling production lines, this production line has the following advantages:

1. It can obtain higher size and shape accuracy, thereby reducing the difficulty of finishing, reducing material consumption and processing costs, and meeting the needs of titanium alloy wire and rod in various fields. According to the user's dimensional accuracy requirements, different numbers of stands can be combined for rolling;

2. The process is flexible and the operation is convenient, and the process regulations can be changed according to the needs to improve the operation rate;

3. The production process is short, the number of holes and the number of frame replacements are reduced, and the operation rate is improved;

4. Rolled by a three-high Y-shaped rolling mill, the rolled piece is in a state of three-way compressive stress, and the deformation conditions are good;

5. The pass type has high commonality, realizes the free rolling of certain specifications, and increases the product specifications;

6. The surface quality of the rolled piece is good, with less cracking and less splitting, which reduces the accidents of continuous rolling stock, so the yield rate is high.

7. The frame is small in size, light in weight, easy to adjust and transport, can save roll changing time, compact structure layout, and small footprint;

8. The rolling speed output and feedback of the entire rolling process is controlled by PLC through the DC speed regulator, the control procedure is simplified, the rolling speed control precision is high, and the speed adjustment is simple and rapid;

9. Adopting modular design, the equipment is easy to manufacture and maintain, which reduces equipment cost and maintenance cost.

Therefore, it is possible to popularize and apply the continuous rolling technology of titanium alloy wire and titanium alloy bar.
