What effect does the internal water jacket have on cooling and heat transfer？The water jacket in the diversion of the high-efficiency crystallizer adopts the integral water-filling inner water sleeve, which overcomes the problem of low processing precision and uneven water seam in the original welding water jacket, ensuring uniformity of the water gap between the corner and the face, and maintaining the cooling speed. Consistently, the generation of corner cracks is avoided. Due to the overall stamping and forming, the inner cavity size and the arc dimensional accuracy are high, and the water gap is accurate, so that the cooling strength of the full length of the crystallizer copper tube is uniform, thereby improving the heat of the crystallizer copper tube. Exchange rate. This structure can also promote slow and uniform cooling at the meniscus, ensuring a uniform and effective shell thickness, which plays a vital role in improving the drawing speed and ensuring the quality of the slab.
