Description

Technical Field

[0001] The utility model relates to the technical field of steel, in particular to a method suitable for detecting the appearance quality of continuous casting square billets. Background Art

[0002] De-squareness of billet refers to the tangential deformation of continuous casting square billet and rectangular billet, which causes the four corners to be not at right angles, usually a pair of acute angles and a pair of obtuse angles. It is a common quality defect in the production process of small square billet. Severe de-squareness will not only lead to steel leakage, which directly threatens production, but also cause steel pile accidents during the rolling process due to the large deformation of the billet, which cannot bite into the rollers, or cannot be rolled and healed in the initial rolling, intermediate rolling and finishing rolling sections. The crack defects caused by de-squareness will cause rolling rotten steel, which seriously affects rolling production. At the same time, the production speed is limited due to the de-squareness of the billet, which restricts the production capacity efficiency.

[0003] Therefore, the measurement of the squareness of the ingot is an important indicator for the appearance quality inspection of the ingot of the continuous casting machine. In actual production, the squareness of the ingot is mostly measured after the ingot is fired. It is necessary to wait for the ingot to cool down, manually measure the cross-section diagonals A and B, and then read the readings against the scale. The absolute value of ∣AB∣ is calculated as the measurement result, and it is judged against the quality control standard. The work is cumbersome. In addition, the process often needs to measure high-temperature ingots. The measurement personnel wear high-temperature isolation labor protection products to enter. The measurement work requires two people to complete it together, one person measures, and the other person uses the scale to assist in reading the value; for the rolling control requirements of high-quality rolled steel products, the squareness of the ingot is required to be less than 5mm. Once the measurement personnel shake their hands while holding the measuring tool, the measured value of the measuring device will have a large deviation. Therefore, this measurement method requires repeated measurement of multiple sets of data to avoid large measurement errors. This measuring tool is low-end, which affects the efficiency and accuracy of the ingot squareness measurement. In addition, in a high-temperature environment, two people working together are prone to safety accidents caused by coordination errors.

[0004] Therefore, there is an urgent need for a rapid measurement device for the de-squareness of continuous casting billets to enable a single person to quickly complete the measurement work. Utility Model Content

[0019] like Figure 1 As shown, a device for quickly measuring the de-squareness of a continuous casting billet comprises a main body, a driving slide rod 1 and an opening and closing bracket.

[0020] The main body includes two measuring arms 4 connected by a rotating shaft, and the two measuring arms 4 rotate around the rotating shaft. The ends of the measuring arms 4 have claws bent inward. The main body is provided with a guide column, and the top of the guide column is provided with a pointer 2. The guide column can be on the rotating shaft of the main body, or on the position where one side of the measuring arm is located above the rotating shaft.

[0021] The driving slide rod 1 is provided with a guide through hole, and the guide post of the rotating shaft is located in the guide through hole. The guide through hole is provided with a scale.

[0022] The opening and closing bracket includes two support rods 3, the upper ends of the support rods 3 are coaxially hinged with the lower end of the driving slide rod 1, and the lower ends of the support rods 3 are respectively hinged with the middle sections of the measuring arms 4 on the same side.

[0023] When in use, the operator pushes the driving slide rod 1 down by hand, opens the measuring arm 4 through the two support rods 3 of the opening and closing bracket, and the two claw tips are against the diagonal of the ingot. At this time, a pointer 2 is provided on the top of the guide column corresponding to the scale on the guide through hole, and the scale value is read directly.

[0024] The axis of rotation is set as the center A, the length of the measuring arm is set as the radius r, and the distance between the axis of rotation and the line connecting the two claw tips is set as d; then the length of the line connecting the two claw tips l is: The difference between the two diagonal lengths is called the squareness. Since the axis (center A) moves along the perpendicular bisector of the line connecting the two claw tips, the distance between the axis and the line connecting the two claw tips is d, which is convenient for measurement. Therefore, the length l of the line connecting the two claw tips can be quickly calculated, and then the squareness can be obtained. Squareness = |l1-l2|.

[0025] Among them, the scale value is determined by: The d value under different l values ​​is calculated in advance, and the point on the perpendicular bisector where the d value is located is marked with scale k, that is, k=l.
