The continuous casting technology is a new technology of continuously casting liquid metal into a casting blank with a certain section shape through a group of special cooling and supporting devices, and fundamentally changes the initial rolling technology of steel ingots. Compared with the traditional die casting steel process, the continuous casting steel has the advantages of simplified production process, high metal yield, low energy consumption, high automation degree, high production rate, good casting blank quality and the like, and becomes one of the epoch-making important technologies in the development history of the steel industry.

In the continuous casting process, if the water gap of a crystallizer copper pipe does not meet the technical standard, uneven cooling of a crystallizer can cause surface cracks of a continuous casting billet, and the continuous casting machine breakout accident can be caused by serious cracks. Therefore, the water gap between the copper pipe of the large and small square billet continuous casting machines and the cooling water jacket must be accurately adjusted to ensure the uniform cooling of the crystallizer, thereby producing continuous casting billets with excellent surface quality and ensuring the smooth production of the continuous casting process.

In the crystallizer maintenance process, the water gap of the copper pipe of the crystallizer of the large and small square billet continuous casting machines is adjusted by using the traditional method, and the water gap value is usually measured by a feeler gauge in a general range of (2 to 8 mm). The water gap value can be measured only after the measuring mode measures 4 times for many times, so that the efficiency is low, the feeler gauge is easy to damage, and the feeler gauge must be taken out when the water gap of the copper pipe is adjusted, so that the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model discloses a conticaster crystallizer water gap dipperstick, including body 1, body 1 is the triangle-shaped structure, and the acute angle edge interval at any acute angle place of body 1 is provided with a plurality of scale marks 3, and the length that 3 representatives of every scale mark do the distance on sharp angle edge of scale mark 3 place position to another sharp angle edge. It can be understood by those skilled in the art that the device is provided with a plurality of scale marks 3 at intervals on one acute angle side of the body 1, in order to ensure the accuracy of measurement, it should be further ensured that the distances between adjacent scale marks 3 are equal, and the length value represented by each scale mark 3 is not the distance from the end point of the acute angle side, but the distance from the point where each scale mark 3 is located to the other acute angle side of the acute angle. The structure arrangement enables the device to be used in practice, one acute angle end of the body 1 provided with the scale mark 3 can be directly inserted into a gap between the crystallizer copper tube 4 and the cooling water jacket 5, the other acute angle side which is not provided with the scale mark 3 is attached to the crystallizer copper tube 4, the end part of the cooling water tube can be close to one side of the scale mark 3 of the body 1 along with the extension of the body 1, and the numerical value displayed by the scale mark 3 on the body 1 is the distance from the point to the other acute angle side, namely the gap value between the copper tube 4 and the cooling water jacket 5, so that the device can rapidly detect the water gap value at one time, and the measurement efficiency is improved. And meanwhile, when the water gap is adjusted, the body 1 can be taken out without being completely taken out, so that the water gap value in the process can be read in real time.

Preferably, in the above device, the body 1 has a right triangle structure. As can be understood by those skilled in the art, in order to measure the device, it is preferable that the body 1 is a right triangle, so that when the acute angle edge provided with the scale marks 3 is in contact with the cooling water jacket 5, another acute angle can be tightly attached to the outer wall of the copper pipe 4, and the whole body 1 is perpendicular to the outer wall of the copper pipe 4, so that the measured data is more accurate.
