Problems solved by technology

[0002] As domestic iron and steel enterprises propose energy saving, emission reduction, transformation and upgrading, and product quality improvement, various domestic iron and steel enterprises have increased equipment production efficiency one after another. From the perspective of continuous casting equipment, it is to improve the utilization efficiency of continuous casting machines and increase the casting speed of casting machines , the casting speed of the slab caster is increased from the original 0.5 to 1.5m / min to 1.2 to 2.8m / min, and the casting speed of the thin plate continuous casting is increased to 4.7~6m / min; The utilization efficiency of the machine and the casting speed of the casting machine are improved, thereby reducing the production cost. This requires a higher material requirement for the mold copper plate, which is the core component of the continuous casting mold. The core is to greatly increase the use of the mold copper plate at a high casting speed. Life and high temperature creep resistance. The existing mold copper plates mainly include Ag-Cu material mold copper plates and Cu-Cr-Zr mold copper plates; Ag-Cu copper plates have low recrystallization temperature and low strength. The improvement of its performance has already shown its lack of performance. High-temperature creep of the copper plate and severe thermal cracking lead to a decrease in life; although the strength of the Cu-Cr-Zr copper plate is high, its thermal conductivity is poor and it is difficult to meet the requirements of the high-speed crystallizer. need
