Description

Technical Field

[0001] This utility model relates to the field of steelmaking equipment, specifically to a device for simulating the liquid level height in a crystallizer. Background Technology

[0002] The automatic control system for casting speed in the crystallizer plays a core role in the continuous casting process. Its necessity and functions are mainly reflected in the following aspects: ensuring billet quality, optimizing production efficiency, and controlling process stability. To ensure the accuracy of the automatic control system, it is necessary to calibrate it regularly. The calibration method is to set up a radiation source and a signal probe in the crystallizer and use the signal probe to receive the signal from the radiation source. This requires using an object to shield the radiation source to simulate the liquid level. The traditional method is to operate it manually by hand, which is inaccurate and cumbersome. Therefore, it is necessary to design a crystallizer liquid level simulation device that is convenient to use and has high accuracy. Summary of the Invention

[0003] The purpose of this invention is to provide a crystallizer liquid level simulation device, which has the advantages of being easy to use and highly accurate.

[0004] The technical solution adopted is as follows:

[0005] A crystallizer liquid level simulation device includes a support plate, a metal block is disposed below the support plate, and a lifting mechanism connected to the metal block is provided on the support plate. The lifting mechanism includes a lead screw that extends vertically. A threaded hole is provided on the support plate that is threadedly connected to the lead screw. A rotating handle is connected to the upper end of the lead screw, and a scale is vertically provided on the side of the lead screw.

[0006] Preferably, the lead screw has a pitch of 4 mm.

[0007] Preferably, the metal block is a cubic block.

[0009] Preferably, a handrail is provided at the upper end of the support plate.

[0010] Preferably, there are two handrails, with the two handles distributed on both sides of the lead screw.

[0011] Compared to existing technologies, the advantages are:

[0012] 1. This utility model utilizes a lifting mechanism to control the lifting and lowering of a metal block, thereby simulating the page height inside the crystallizer. The metal block is positioned at different locations to simulate different liquid level heights, which is used to calibrate the automatic speed control system.

[0013] 2. In this utility model, a handrail is provided at the upper end of the support plate. The operator holds the handrail to limit the position of the plate and prevent the support plate from rotating with the lead screw. Attached Figure Description
