Description

Technical Field

[0001] The invention relates to the technical field of sampling and analysis, and in particular to a sampling and analysis device for high-carbon ferrochrome smelting. Background Art

[0002] In the production of high-carbon ferrochrome, it is necessary to analyze the molten iron smelted in the electric furnace to find out the carbon equivalent, carbon content, silicon content, etc. in the molten iron. Therefore, it is necessary to obtain molten iron samples and analyze them. The molten iron sampling location is mainly at the iron outlet ditch. At present, on-site sampling is generally carried out by scooping it out with an iron spoon, pouring it into a sample mold, and sending it for inspection after cooling. Since this method requires manual standing next to the iron ditch, the high temperature of 1500 degrees will directly radiate people and cause adverse effects on human health. At the same time, molten iron is easy to splash, which is very dangerous.

[0003] The existing sampling method is not scientific for the actual quality of pig iron, and is easy to mix with other components during operation. At the same time, there are residual components of pig iron from dozens of times stuck to the wall of the molten iron mold from the sample spoon, which is difficult to explain and distinguish the true composition of the molten iron in this furnace, directly affecting the basis and credibility of the steel plant to correctly grasp the true composition of the molten iron. Therefore, we have made improvements to this and proposed a sampling and analysis device for high-carbon ferrochrome smelting. Summary of the invention

[0028] The supporting mechanism 1 comprises a supporting frame 11, a roller 12 is installed at the bottom of the supporting frame 11, a rotating turntable 14 is installed at the upper end of the supporting frame 11, a rotating frame 13 is connected to the upper end of the rotating frame 13, a connecting shaft 15 is installed at the upper end of the rotating frame 13, cranks 16 are connected to both sides of the connecting shaft 15, a connecting box 17 is fixedly connected to the upper end of the connecting shaft 15, and a mounting groove 18 is provided in the middle of the connecting box 17. The arrangement of the supporting frame 11 and the roller 12 facilitates the transportation of the device as a whole, so that the device can be used in the iron ditch of high-carbon ferrochrome smelting, and the connecting shaft 15 is connected to the crank 16, so that when the crank 16 is shaken, the connecting box 17 and the sampling long arm 2 are driven to swing together by a lever, and the rotating frame 13 and the supporting frame 11 are rotatably connected, so as to facilitate the rotation of the overall direction of the sampling long arm 2, so that the device is more convenient to use.

[0029] The sampling long arm 2 includes a rocker arm 21, racks 22 are installed on both sides of the rocker arm 21, a movable buckle 25 is connected to the rear end of the rocker arm 21, a support plate 23 is connected between the rocker arm 21 and the movable buckle 25, a connecting groove 24 is provided in the middle of the support plate 23, and two swing grooves 26 are provided at the middle ends of the support plate 23, connecting columns 27 are installed inside the two swing grooves 26, a first swing rod 28 and a second swing rod 29 are connected inside the two swing grooves 26, and springs 210 are installed on the first swing rod 28 and the second swing rod 29, the bottom surface of the sampling spoon 4 is connected to the support plate 23, the rocker arm 21 protects the sampling spoon 4 on both sides, and the crank handle 16 is shaken to make the connection box 17 and the sampling long arm 2 move along the whole. The connecting shaft 15 is turned over to press the rear end of the sampling long arm 2 downward. Under the influence of gravity, the sampling spoon 4 moves on the support plate 23 as the support plate 23 bends and twists until it moves to the movable buckle 25. The rear end of the support plate 23 separates the first template 41 and the second template 42, the molten iron is cooled and formed, and the sample is taken out. The first swing arm 28 and the second swing arm 29 are set so that when the sampling long arm 2 is low at the front and high at the back, the sampling spoon 4 is pushed to slide to the front end of the sampling long arm 2 by the second swing arm 29. Conversely, when the sampling long arm 2 is low at the back and high at the front, the sampling spoon 4 is pushed to slide to the rear end of the sampling long arm 2 by the first swing arm 28, and the weight of the sampling spoon 4 itself provides power for the sliding of the sampling spoon 4.

[0031] The rear end of the support plate 23 is higher than the front end, and the rear end of the support plate 23 is bent into two opposite 'C' shapes. The 'C'-shaped position of the support plate 23 separates the first template 41 and the second template 42 to both sides, and separates the sampled discus from the first template 41 and the second template 42, so that the discus falls into the interior of the cooling box 3 below, and the discus is collected and stored.

[0032] The cooling box 3 includes a water tank 31 , a water outlet pipe 32 is installed on the bottom of the water tank 31 , and the interior of the water tank 31 is filled with cold water to cool and store the discus sample formed inside the sampling spoon 4 , and the cooling water is replaced through the water outlet pipe 32 .

The connecting buckle 48 is slidably installed inside the connecting groove 24, and a temperature measuring probe 47 is fixedly connected to the bottom of the connecting buckle 48. The first template 41 and the second template 42 are used to hold molten iron when they are merged, and are separated after the discus is cooled and formed, so as to facilitate the removal of molten iron samples and the analysis and detection of the molten iron. At the same time, the temperature measuring probe 47 installed at the bottom of the connecting buckle 48 detects the temperature of the molten iron.

[0034] The upper ends of the first template 41 and the second template 42 are both provided with sampling ports 45, and the bottom of the sampling port 45 is connected to a molding cavity 46. The sampling port 45 scoops up the molten iron and fills it into the molding cavity 46 to form a discus sample in the shape of a round cake, which is convenient for obtaining the molten iron sample and analyzing it.
