Description

Technical Field

[0001] The invention belongs to the technical field of nonferrous metal smelting, and specifically relates to a point-type process and device for rapidly measuring the carbon value of titanium sponge by reducing titanium tetrachloride. Background Art

[0002] Titanium chloride, also known as titanium tetrachloride, is an inorganic compound with the chemical formula TiCl4. It is a colorless liquid at room temperature. It is mainly used to prepare sponge titanium and titanium dioxide, and can also be used as a catalyst.

[0003] Sponge titanium production is the basic link of the titanium industry. It is the raw material of titanium materials, titanium powder and other titanium components. Turn ilmenite into titanium tetrachloride, put it into a sealed stainless steel tank, fill it with argon gas, and react with magnesium metal to obtain "sponge titanium". The carbon content of sponge titanium is an important quality indicator, which has a significant impact on the performance and use of the product. The lower the carbon content of sponge titanium, the higher its quality and the wider its application range.

[0004] In the prior art, the carbon value in titanium sponge is mainly detected through online infrared spectroscopy and laser induced breakdown spectroscopy, and the carbon value in titanium sponge is detected by installing the detection equipment at the key position of the production line. Although the above method can detect the carbon value in titanium sponge in real time, its equipment cost is relatively high, and the requirements for the detection environment and technical expertise are relatively strict. In order to reduce the detection cost and technical difficulty, the prior art also uses temporary sampling to chemically analyze the samples obtained from the production line to determine the carbon content. Although this method can reduce equipment costs and technical requirements, it is easy to interfere with the production process of titanium sponge during the sampling process. Sampling requires interrupting the operation of the production line or adjusting production parameters, which will affect production efficiency and product quality. Therefore, there is an urgent need for a titanium tetrachloride reduction rapid measurement of the carbon value of titanium sponge point process and device, which can solve the problem in the prior art that it is easy to interfere with the production of titanium sponge during sampling. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a point-type process and device for rapidly measuring the carbon value of sponge titanium by reducing titanium tetrachloride, which can reduce the interference with sponge titanium production during the sampling process.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] The titanium tetrachloride reduction rapid measurement of the carbon value of titanium sponge point process comprises the following steps:

[0008] Step 1: Adding materials, respectively introducing gaseous titanium tetrachloride and liquid magnesium into the feed pipe and magnesium adding pipe of the reduction furnace;

[0009] Step 2: Reaction, adjusting the temperature and pressure in the reduction furnace, and introducing argon gas into the reduction furnace to react titanium tetrachloride and liquid magnesium;

[0010] Step 3: Sampling, adjusting the feed rate of liquid magnesium and gaseous titanium tetrachloride, so that the liquid magnesium and gaseous titanium tetrachloride react above the sampling platform, continuously introducing argon gas under the sampling platform of the reduction furnace to blow away the attached sponge titanium, and after the sponge titanium on the sampling platform is dispersed, the sponge titanium generated by the reaction on the sampling platform is taken out;

[0011] Step 4: Testing: Testing the taken out titanium sponge to detect its carbon content.

[0012] Furthermore, in step 2, the temperature in the reduction furnace is adjusted to 800-1000° C. and the pressure is adjusted to 0.1-0.5 MPa.

[0013] Furthermore, the duration of the introduction of argon in step 3 is 1-2 hours.

[0014] Furthermore, in step three, after sampling, the feed rates of liquid magnesium and gaseous titanium tetrachloride are adjusted so that the liquid magnesium falls outside the sampling platform.

[0015] Furthermore, in step three, when the feed rate of liquid magnesium is increased, the ventilation rate of argon is increased.

[0016] Furthermore, in step three, the reduction furnace is depressurized every time the argon gas introduction time exceeds a preset time.

[0017] A device for rapidly measuring the carbon value of titanium sponge by reducing titanium tetrachloride, including a reduction furnace;

[0018] A reduction chamber is arranged in the reduction furnace; a sampling platform is arranged in the center of the reduction chamber, the sampling platform penetrates the bottom of the reduction furnace, a through groove is arranged inside the sampling platform, an inner valve is arranged on the inner side of the top of the through groove, an outer valve is arranged at the bottom of the through groove, a sampling piece is arranged between the inner valve and the outer valve, round holes are evenly arranged on the sampling piece, a sampling bracket is arranged at the bottom of the sampling piece, the sampling piece and the through groove are slidably matched, a vent is arranged in the side wall of the through groove, and the vent is used to transport argon gas; a feeding tube and a magnesium adding tube are respectively arranged on both sides of the reduction chamber, the feeding tube and the magnesium adding tube both extend to the top of the sampling platform, wherein when the initial velocity of the fluid flowing out of the feeding tube and the magnesium adding tube is greater than the preset velocity, the fluid just falls into the sampling platform; a cover body is arranged on the top of the reduction furnace, and the cover body is used to seal the reduction chamber.

[0019] Furthermore, a plurality of supporting legs are provided at the bottom of the reduction furnace.

[0020] Furthermore, an air release valve is arranged on the cover body.

[0021] Furthermore, the top of the sampling platform is at a preset distance from the cover plate.

[0022] The above scheme has the following beneficial effects:

[0023] 1. Compared with the traditional temporary sampling method, this scheme adds gaseous titanium tetrachloride and liquid magnesium from the feed pipe and magnesium adding tube respectively, and adjusts the feed speed so that the sponge titanium generated by the reaction of liquid magnesium and titanium tetrachloride falls on the sampling piece, so as to collect samples; at the same time, by introducing argon gas into the through slot, the air pressure in the through slot increases after the argon gas enters the through slot. At this time, the liquid magnesium that falls on the sampling piece will continue to tumble under the blowing of argon gas, so as to prevent the generated sponge titanium from adhering to the inner wall of the through slot. Then, by closing the inner valve and opening the outer valve, the sampling piece is taken out of the through slot, and the carbon value of the sponge titanium that falls on the sampling piece is tested. This scheme can obtain samples without interrupting the production process by adjusting the feed speed, thereby reducing interference with sponge titanium production.

[0024] 2. In this scheme, the argon vent is set below the sampling piece. When argon is introduced, the argon can take away the heat near the sampling piece. Argon has a high thermal conductivity and can quickly absorb heat to promote rapid cooling of sponge titanium, while reducing the temperature of the sampling piece, thereby avoiding excessive temperature when the sampling piece is taken out, which threatens the safety of the staff.

[0025] 3. In this scheme, when increasing the feeding speed of liquid magnesium, the ventilation speed of argon is also increased. If the magnesium feeding speed is too fast, the liquid magnesium accumulated in the sampling platform will increase. By increasing the ventilation speed of argon, the churning of liquid magnesium can be intensified, and liquid magnesium can be prevented from flowing out of the circular hole of the sampling piece, causing waste. At the same time, the contact between liquid magnesium and gaseous titanium tetrachloride is more sufficient, which increases the reaction rate. Sufficient contact can make the liquid magnesium more evenly distributed during the reaction, making the reaction process more controllable. This helps to reduce the risks in the production process and improve the stability and consistency of sponge titanium samples.

[0026] 4. In this scheme, during the sampling process, the inner valve is opened and the outer valve is closed. After the titanium sponge is generated on the sampling piece, the inner valve is closed and the outer valve is opened. During the entire titanium sponge sampling process, no external pollutants will enter the reduction furnace to affect the purity and quality of the titanium sponge. BRIEF DESCRIPTION OF THE DRAWINGS

It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0032] The following is further described in detail through specific implementation methods:

[0033] The figure marks in the drawings of the specification include: reduction furnace 1, cover body 2, support legs 3, feed pipe 101, magnesium adding tube 102, reduction chamber 103, sampling platform 104, inner valve 105, sampling piece 106, vent 107, sampling bracket 108, outer valve 109, through groove 110, and air release valve 201.

[0034] Embodiment 1 is basically as attached Figure 1 As shown:

[0035] The titanium tetrachloride reduction rapid measurement of the carbon value of titanium sponge point process comprises the following steps:

[0036] Step 1: Adding materials, respectively introducing gaseous titanium tetrachloride and liquid magnesium into the feed pipe 101 and the magnesium adding pipe 102 of the reduction furnace 1;

[0037] Specifically, when adding materials, the speeds at which titanium tetrachloride and liquid magnesium enter the reduction furnace 1 are respectively regulated, mainly the initial speed of the liquid magnesium leaving the magnesium adding tube 102 , so that the liquid magnesium can fall outside the sampling platform 104 .

[0038] Step 2: Reaction, adjusting the temperature and pressure in the reduction furnace 1, and introducing argon gas into the reduction furnace 1 to react titanium tetrachloride and liquid magnesium;

[0039] Specifically, the temperature in the reduction furnace 1 is adjusted to 800-1000° C., and the pressure is adjusted to 0.1-0.5 MPa.

[0040] Step 3: Sampling, adjusting the feed rate of liquid magnesium and gaseous titanium tetrachloride, so that the liquid magnesium and gaseous titanium tetrachloride react above the sampling platform 104, continuously introducing argon gas below the sampling platform 104 of the reduction furnace 1 to blow away the attached sponge titanium, and after the sponge titanium on the sampling platform 104 is dispersed, the sponge titanium generated by the reaction on the sampling platform 104 is taken out;

[0041] Specifically, by increasing the feeding speed of gaseous titanium tetrachloride and liquid magnesium, the liquid magnesium can just fall into the through groove 110 of the sampling platform 104 after leaving the magnesium adding tube 102, and part of the sponge titanium generated after the reaction in the air will also fall together. The liquid magnesium and part of the sponge titanium falling into the through groove 110 will not pass through the sampling piece 106 under the pressure of argon gas. At this time, the liquid magnesium is tumbling in the area surrounded by the sampling piece 106 and the through groove 110, and reacts with the gaseous titanium tetrachloride to generate sponge titanium. Since the liquid magnesium is constantly tumbling, the generated sponge titanium will not adhere to the side wall of the through groove 110; after a period of time, the speed of the liquid magnesium flowing out of the magnesium adding tube 102 is reduced. At this time, there will be no new liquid magnesium added above the sampling piece 106, until the liquid magnesium above the sampling piece 106 is completely reacted, the inner valve 105 is closed, and the outer valve 109 is opened to extract the sampling piece 106 from the bottom of the sampling platform 104, so as to obtain the sponge titanium sample.

[0042] Step 4: Testing: Testing the taken out titanium sponge to detect its carbon content.

[0043] Example 2

[0044] This embodiment provides a device for rapidly measuring the carbon value of titanium sponge by reducing titanium tetrachloride, which is applicable to the point-type process for rapidly measuring the carbon value of titanium sponge by reducing titanium tetrachloride in Embodiment 1, and includes a reduction furnace 1.

[0045] A reduction chamber 103 is provided in the reduction furnace 1; a sampling platform 104 is welded and fixed at the center of the reduction chamber 103, the sampling platform 104 penetrates the bottom of the reduction furnace 1, a through groove 110 is provided inside the sampling platform 104, the through groove 110 connects the reduction chamber 103 with the outside, an inner valve 105 is fixedly connected to the inner side of the top of the through groove 110 through a flange, an outer valve 109 is fixedly connected to the bottom of the through groove 110 through a flange, a sampling piece 106 is provided between the inner valve 105 and the outer valve 109, circular holes are evenly provided on the sampling piece 106, a sampling bracket is welded and fixed to the bottom of the sampling piece 106, the sampling piece 106 is slidably matched with the through groove 110, and the sampling bracket is used to support the sampling piece 106 so that the sampling piece 106 can carry the generated sponge titanium. A vent 107 is provided in the side wall of the through groove 110, and the vent 107 is used to transport argon gas; a feeding pipe and a magnesium adding pipe 102 are respectively welded and fixed on both sides of the reduction chamber 103, and the outlets of the feeding pipe and the magnesium adding pipe 102 extend above the sampling platform 104, wherein when the initial velocity of the fluid flowing out of the feeding pipe and the magnesium adding pipe 102 is greater than the preset velocity, the fluid just falls into the sampling platform 104; a cover body 2 is fixedly connected with bolts on the top of the reduction furnace 1, and the cover body 2 is used to seal the reduction chamber 103. A vent valve 201 is fixedly connected to the cover body 2 through a flange, and the vent valve 201 is used to reduce the air pressure in the reduction chamber 103. The top of the sampling platform 104 is at a preset distance from the cover plate. The preset distance in this embodiment is based on the amount of sponge titanium generated in the reduction chamber 103, that is, the generated sponge titanium will not adhere to the magnesium adding pipe 102 and the feeding pipe 101. In this embodiment, the inner valve 105 is a high-temperature ball valve, and the outer valve 109 is a high-temperature gate valve.

[0046] A plurality of legs 3 are welded and fixed to the bottom of the reduction furnace 1 to facilitate opening the outer valve 109 from the bottom of the sampling platform 104 and taking out the sampling piece 106 .

[0047] Specific implementation process:

[0048] For example, during the normal production process of sponge titanium, the reduction furnace 1 is sealed and placed in an electric furnace for heating, gaseous titanium tetrachloride is introduced through the feed port, liquid magnesium is introduced through the magnesium adding tube 102, and argon is introduced into the reduction chamber 103 through the vent 107. The temperature in the reduction chamber 103 is adjusted to 800-1000°C, and the pressure is increased to 0.1-0.5MPa. At this time, the liquid magnesium enters the reduction chamber 103 and directly falls to the bottom of the reduction chamber 103 without flowing into the sampling platform 104. The gaseous titanium tetrachloride contacts the liquid magnesium at the bottom of the reduction chamber 103 and reacts to generate sponge titanium.

[0049] When it is necessary to temporarily detect the carbon value of sponge titanium, the flow rate of liquid magnesium is temporarily increased so that the initial speed of liquid magnesium when flowing out of the magnesium adding tube 102 is greater than the preset speed, so that part of the liquid magnesium falls into the area formed by the sampling piece 106 and the through groove 110. The preset speed in this embodiment is the horizontal initial speed of liquid magnesium flowing out of the magnesium adding tube 102 when the liquid magnesium can just fall into the through groove 110 of the sampling platform 104 after flowing out of the magnesium adding tube 102. Similarly, the flow rate of the gaseous titanium tetrachloride in the feed pipe 101 is also increased so that the intersection point of the liquid magnesium and the gaseous titanium tetrachloride is located above the through groove 110. In the process of increasing the flow rate of the liquid magnesium, the sponge titanium generated by the reaction of the liquid magnesium and the gaseous titanium tetrachloride at the intersection will fall onto the sampling piece 106 in the through groove 110 together with the magnesium liquid. At this time, the argon gas introduced into the vent 107 below the sampling piece 106 enters the reduction chamber 103 through the circular hole on the sampling piece 106, and at the same time disperses the liquid magnesium near the circular hole, so that the liquid magnesium on the sampling piece 106 is constantly churning (i.e., similar to the continuous generation of bubbles in the solution), thereby making the liquid magnesium and the gaseous titanium tetrachloride contact more fully, and at the same time preventing the sponge titanium generated in the through groove 110 from adhering to the side wall of the through groove 110 or condensing on the side wall. When the argon gas is introduced for a certain period of time, the vent valve 201 is opened to discharge the excess argon gas into the reduction chamber 103 to avoid excessive pressure in the reduction chamber 103 .

[0050] After the flow rate of the liquid magnesium returns to normal, due to the low initial velocity of the liquid magnesium, the liquid magnesium will not have enough power to fall into the through groove 110 of the sampling platform 104. At this time, the liquid magnesium falls into the bottom of the reduction chamber 103 and performs normal sponge titanium production. At this time, the continuously introduced argon gas will cool the sponge titanium generated on the sampling piece 106 to avoid excessive temperature when taking out the sponge titanium, causing safety accidents and threatening the personal safety of the staff. When sampling, close the inner valve 105, open the outer valve 109, take out the sampling bracket from the bottom of the through groove 110, and test the sponge titanium on the sampling piece 106.
