Alloy steel casting process compared with carbon steel has the following characteristics:
(1) According to the needs of the cast steel, the liquid steel purity, composition and pouring temperature, especially the control of trace element content, are required to achieve the specified value. This special steel continuous casting furnace must be equipped with refining equipment.
(2) Mold should be used high-frequency, small amplitude vibration.
(3) Selection of good performance and the protection of the whole process of pouring casting to ensure the quality of slab.
(4) The best use of large capacity, deep melt pool, and build a retaining wall, the dam of the tank, give full play to the metallurgical function of the middle tank.
(5) It should use the appropriate refractory materials to reduce consumption and improve the purity of steel.
(6) The use of mold level automatic control to reduce surface fluctuations.
