Description

Technical Field

[0001] The present invention relates to the technical field of iron column detection, and specifically to a strength detection device and method for the reaction after replacing coke with semi-coke Background Art

[0002] In the process of blast furnace ironmaking, coke mainly serves as a heat source, reducing agent, carburizing agent, and burden column skeleton. Due to the increasing shortage of high-quality coking coal resources in China, and the fact that the role of the burden column skeleton of coke in the blast furnace cannot be replaced, finding a method to reduce the coke ratio in the blast furnace and save ironmaking costs has become an urgent problem to be solved. Semi-coke is made from high-quality Jurassic clean coal blocks rich in the Shenfu coalfield. As a new type of carbon material, semi-coke has high fixed carbon, high specific resistance, high chemical activity, low ash content, low aluminum, low sulfur, and low phosphorus. Its reactivity is very high, and the initial temperature and intense reaction temperature of its carbon solution reaction are much lower than those of metallurgical coke. Therefore, it is proposed to use semi-coke to replace coke breeze and add it to the blast furnace to reduce the loss of metallurgical coke. Mix semi-coke and iron ore into the blast furnace. Semi-coke first undergoes a carbon solution loss reaction with CO2 in the blast furnace, reducing the carbon solution loss reaction with large pieces of metallurgical coke, protecting the large pieces of metallurgical coke, enabling the large pieces of metallurgical coke to fully play the role of the skeleton, reducing the use of large pieces of coke. At the same time, it can improve the indirect reduction reaction in the lump zone and reduce the direct reduction reaction, thereby reducing coke consumption. To a certain extent, it provides a basis for reducing the coke ratio of large pieces of metallurgical coke and the requirements of the blast furnace for the thermal properties of coke, and further reducing the proportion of high-quality coking coal and fat coal in coking coal blending, alleviating the shortage of coking coal resources in China. When conducting blast furnace ironmaking experiments using semi-coke, it is necessary to conduct performance tests on the produced iron columns. Force sensors are used to detect mechanical quantities such as tension, tensile force, pressure, weight, torque, internal stress, and strain. A force sensor is a device that converts the magnitude of force into relevant electrical signals. Force is the direct cause of the movement and change of matter. When conducting a tensile strength test, due to the special nature of the iron column, it is easy for the iron column to fall off the fixture during the tensile strength test, resulting in experimental failure and easily causing injury to experimental personnel. Therefore, we propose a strength detection device and method for the reaction after replacing coke with semi-coke Summary of the Invention

9. The device for detecting the strength of semi-coke after the reaction of replacing coke according to claim 8, characterized in that: The two groups of the first connecting pieces (45) are fixedly connected to the opposite side with an insertion rod (48), and the outer sides of the two groups of the insertion rods (48) are slidably connected to a slide tube (47). The opposite ends of the insertion rods (48) are fixedly connected to a blocking piece (49), and the blocking piece (49) is located on the inner side of the slide tube (47). The outer side of the insertion rod (48) is fixedly connected to a slide plate (410), and a bayonet (411) is provided on the outer side of the slide plate (410). The upper and lower ends of the slide tube (47) are fixedly connected to a clamping piece (412), and a socket (413) is provided on the outer side of the clamping piece (412), and the socket (413) fits with the slide plate (410).

10. A method for detecting the strength of semi-coke after a reaction in which semi-coke replaces coke, applied to a device for detecting the strength of semi-coke after a reaction in which semi-coke replaces coke according to any one of claims 1 to 9, characterized in that: include: Step 1: Start the driving motor (415) to drive the rotating rod (416) to rotate, and then use the second gear (418) to drive the first gear (417) to rotate, and then drive the third threaded rod (43) to rotate on the fixed plate (42), and then use the threaded cylinder (44) to drive the second connecting plate (46) to move, so as to adjust the position of the cross plate (31); Step 2: Place the iron column to be tested between the two sets of clamps (333), then rotate the rotating cap (339) to drive the two sets of sliders (336) to slide inside the fixed shell (332), and clamp the iron column with the clamps (333); Step 3: Rotate the threaded ring (3413) to move on the first threaded rod (331), drive the sliding ring (343) to move, pull the pull rod (344) to move, use the connecting rod (345) to pull the bent rod (347) to tilt up, so that the compression shell (348) is closely attached to the surface of the iron column, and the iron column is further fixed; Step 4: Start the hydraulic rod (32) to drive the first threaded rod (331) to move upward, and perform a tensile test on the iron column. As the first threaded rod (331) moves upward, the threaded ring (3413) can be pulled upward, and the pull rod (344) can be further pulled upward, so that the compression shell (348) can further clamp the iron column.
