Abstract
Description
Technical Field
[0001] The utility model relates to a PS nickel converter tuyere zone length measuring device, belonging to the technical field of metallurgical equipment. Background Art
[0002] In modern nickel pyrometallurgy, the refractory bricks are lined in the tuyere of the converter to isolate the high-temperature melt from the converter body and protect the steel shell of the converter body from being burned through by the high-temperature melt. However, the tuyere is the area with the most intense reaction in the furnace, and the consumption rate of the tuyere bricks is also the fastest consumption of refractory bricks in the furnace. When the length of the refractory bricks in the tuyere is reduced to a certain extent, there will be a risk of leakage, and the furnace should be shut down for maintenance in a planned manner. Therefore, in the daily production process, the length of the refractory bricks in the tuyere must be measured in a planned manner.
[0003] The utility model patent with patent number CN2020214160488 provides a tool for measuring the length of refractory bricks in the eye area. A steel pipe with a small hook on the head is extended from the eye to the eye area. The hook clamps the refractory bricks in the furnace. The position of the steel pipe at the base of the eye is detected, and a tape measure is used to measure the distance from the hook on the head of the steel pipe to the base of the eye. The measurement data is not accurate and intuitive, and there is a risk of burns. Utility Model Content
[0004] The utility model provides a PS nickel converter tuyere zone length measuring device, which greatly simplifies the complexity of the measuring device and facilitates maintenance while ensuring the accuracy of the measuring result.
[0005] To this end, the utility model adopts the following technical solutions:
[0006] A PS nickel converter eye zone length measuring device comprises a measuring rod, one end of the measuring rod is provided with a hook head, and the other end is provided with a handle; a conical sleeve is also sleeved on the measuring rod, and the diameter of the sleeve near the handle is larger than that near the hook head.
[0007] The length of the measuring rod is 2 to 3 times the original length of the eye area, and scale lines are arranged on the measuring rod, with the hook being the zero point of the scale lines.
[0008] Compared with the prior art, the utility model has a simple structure and can realize fast and accurate measurement of the tuyere length, thus providing a reliable basis for safe shutdown of the converter, maximizing the utilization of tuyere area bricks, increasing the converter life, and reducing the converter production cost. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural schematic diagram of the utility model.
[0010] In the figure, 1-hook, 2-measuring rod, 3-sleeve, 4-scale line, 5-handle. DETAILED DESCRIPTION
[0011] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods.
[0012] like Figure 1 As shown, a device for measuring the length of the eye zone of a PS nickel converter comprises a measuring rod 2, a hook head 1 is provided at one end of the measuring rod 2, and a handle 5 is provided at the other end; a conical sleeve 3 is also sleeved on the measuring rod 2, and the diameter of the sleeve 3 near the handle 5 is larger than the diameter of the sleeve 3 near the hook head 1. The length of the measuring rod 2 is 2 to 3 times the original length of the eye zone, and a scale line 4 is provided on the measuring rod 2, and the hook head is the zero point of the scale line.
[0013] The specific dimensions of each component are as follows: the hook is 5mm long, the handle is an ellipse of 15mm×8mm, the measuring rod is 2300mm long, the measuring range is 1200mm, the hook, handle and measuring rod are integrally formed, and the diameter of the white steel rod used is 5mm. The sleeve is a 304S stainless steel tapered cylinder with a minimum outer diameter of 15mm, a maximum outer diameter of 76mm and a length of 300mm.
[0014] When in use, insert the hook 1 deep into the wind eye and hang it firmly, move the sleeve 3 so that the sleeve 3 is inserted into the wind eye and clamped with the muffler pressing piece outside the wind eye area, and record the scale line reading opposite to the outer end of the sleeve 3 at this time, which is the length of the wind eye area. Note: Since it is necessary to measure and record the change rate multiple times, the length of the sleeve 3 can be ignored.
[0015] In addition, since the sleeve 3 is half-inserted into the air eye, it is less affected by the uneven surface of the muffler pressing plate (weld scars and deformation), so the measurement is more accurate than the flat abutment method; and after being pressed tightly, a wedge-shaped force relationship is formed, and the staff can sometimes loosen the handle and record the readings, which is convenient and quick.
