Continuous casting billet online weight fixing system

Abstract

The invention discloses a continuous casting billet online weight fixing system. The continuous casting billet online weight fixing system comprises continuous casting billets, a flame cutting device and a weight measuring device, the flame cutting device is used for cutting the continuous casting billets, and the weight measuring device is used for measuring the weights of the continuous casting billets. The weight measuring device comprises a computer, a length measuring module, a width measuring module and a thickness measuring module, wherein the length measuring module, the width measuring module and the thickness measuring module are electrically connected with the computer and used for measuring the lengths, the widths and the thicknesses of the continuous casting billets correspondingly. The computer calculates the real-time weights of the continuous casting billets by combining the measured sizes of the continuous casting billets according to the density information, obtained in advance, of the continuous casting billets and sends the real-time weights to the flame cutting device for fixed weight cutting of the continuous casting billets. The length measuring module comprises a laser range finder used for measuring the level at which the flame cutting device arrives at an original position so as to compensate and correct the measured lengths of the continuous casting billets. The continuous casting billet online weight fixing system can accurately calculate the real-time weights of the continuous casting billets for fixed weight cutting of the continuous casting billets, and therefore the weight deviation of the cut continuous casting billets is stabilized within an allowable range, and the requirement of efficient continuous casting production can be met.

Description

technical field [0001] The invention relates to the field of steelmaking and continuous casting, in particular to an online weighing system for continuous casting slabs. Background technique [0002] In the high-efficiency continuous casting production process, due to factors such as mold wear, molten steel pressure, casting speed, density, and specific gravity changes, the same casting strand casts continuous casting slabs of the same length at different times, but there are large differences in weight. This makes the continuous casting slab affect the yield of the rolled product when the next rolling process is carried out. In order to reduce waste and improve the yield of rolled products, it is necessary to carry out fixed weight cutting. The fixed-weight cutting in the prior art mainly uses a weighing sensor to weigh the weight of the cut continuous casting slab, and then compares the weight with a set value and then feeds it back to the measuring system. The disadvant...

Problems solved by technology

The disadvantage is that the temperature of the continuous casting slab just after cutting is high (about 800°C), and the scale frame, load cell and lifting device are affected by heat radiation and water vapor, etc., the weight error of the weighed out is large and the life of the load cell Short, still can not meet the requirements of high-efficiency continuous casting production
