Recently, the Panzhihua Iron and Steel and Panzhihua Iron and titanium grade 4 Steel Institute research group Titanium Company titanium sponge plant together carry 74% grade titanium slag of molten salt chlorination industrial application test and achieved preliminary results, it can greatly reduce the cost of titanium sponge production of raw materials for titanium sponge plant the use of low-grade titanium slag molten titanium grade 3 chloride to provide a solid technical support.
It requires the use of molten salt chlorination more than 78% of grade chlorination slag. Panzhihua Iron and titanium slag production mainly in the 74 percent grade acid-soluble titanium slag-based. When Panzhihua ore smelting slag chloride 78%, due to the material characteristics, so that the difference between the smelting furnace conditions, high costs, compared with 74% slag. Group tracking the testing process, focusing on the influence of 74% grade titanium slag of molten chloride. Currently, 74% grade titanium slag of molten salt chlorination test successfully completed and achieved the expected results.

Pangang Titanium titanium sponge plant spread the good news, after two years of technical research, the plant successfully developed a "full utilization of Panzhihua 74% grade titanium slag of molten salt chlorination fine titanium tetrachloride production of" advanced technology, becoming the the first use of 74% grade titanium slag of molten salt chlorination fine titanium tetrachloride production enterprises, vanadium and titanium resources in Panxi provides a new titanium grade 5 path utilization.
It is reported that 74% of the whole Panzhihua grade titanium slag with low volume, high impurity content, the higher chlorine content in the exhaust, high production of waste salt, lye consumption is large, therefore, only as titanium dioxide feedstock, can not as titanium sponge production of raw materials. After nearly two years to carry out the production of chlorinated research, from April 1 this year, the plant optimization through the adoption of technology, equipment upgrading, refining operations and other measures in the chlorination process, the smooth realization of the full 74% grade titanium Panzhihua production of refined molten titanium grade 7 slag chloride titanium tetrachloride major technological breakthrough, can reduce the cost per ton of titanium sponge 1329 yuan.

Due to the presence of surface oxide titanium block after grade 5 titanium cutting, easily mixed with coolant and metal-cutting equipment and other issues, recycling more difficult. Therefore, the development of a low-grade titanium chloride reacted with the iron scrap, recycling processes titanium tetrachloride gas.
Titanium tetrachloride is reduced in the next process, thereby obtaining titanium. Ferric chloride is difficult to handle the waste generated during the smelting of titanium. Rational use of chlorinating agents can reduce costs, improve resource efficiency. All along, titanium scrap and iron chloride will react after the titanium surface covered with a layer of iron, titanium and ferric chloride lead to termination of the reaction. This time, to add magnesium titanium alloy bar chloride, samarium molten salt as a medium to make it happen with the titanium chlorination. Because of ferric chloride and titanium without the direct reaction, the reaction stops phenomenon and therefore does not appear. In the experiment, a titanium rod after 1100 ℃ treatment, one hour can take place completely vaporized.

Electrostatic separation is an effective means of titanium grade 2 obtaining high-grade titanium concentrates. Electrostatic separation effect of coarse material is superior to fine grade material. Tests showed that re-election of an electric-election process of the transfer of coarse grade material containing Ti0> 28%, fine grade material containing Ti0> 32%. In a small experiment and expand the trials are successful, based on the March to June 1979 Research Institute processing plant re-election in an electrical workshop selected industrial test, process scale magnetic concentrator tailings 240 ~ 260t. The main equipment medical grade titanium used for the FLX -1 type 600 × 360mm, 6600 × 339mm spiral concentrator, 1200 × 720mm spiral chute and YD - 3A-type high-voltage election machines. In magnetic separation tailings containing TiO8 70%, C0O.016% condition was obtained containing Ti046 19%, 39.38% recovery of titanium concentrate; Containing C00 .24%, 5.89% sulfur recovery cobalt concentrate. Titanium plant construction to have provided reliable information.

Discuss technical and efficacy of AO mini titanium metal plate and nail treatment metacarpal fracture. Methods: 21 patients with 22 metacarpal fracture, titanium bar supplier using a special AO mini titanium plate internal fixation nail treatment, Results: Patients were followed up for 3-6 months, fracture healing rate of 100%, hurt palm knuckles and interphalangeal joints flexion function returned to normal. Conclusion: For the rehabilitation of post-traumatic higher requirements metacarpal fracture, improve titanium alloy wire the traditional treatment techniques, the use of features of AO mini titanium plate and nail row solid internal fixation, combined with early postoperative functional exercise, obtained satisfactory therapeutic results; metacarpal fracture is an ideal treatment.
