Background
In recent years, the die casting ratio has gradually decreased, but continuous casting cannot be substituted for the smelting of steel materials with large thickness and high strength. Die casting refers to casting qualified molten steel into an ingot die to solidify the molten steel, so as to form a solid steel ingot with good surface, pure, uniform and compact interior. Die casting is classified into an upper injection method and a lower injection method, and the lower injection method is widely used at present due to simple operation and high efficiency. Molten steel slowly rises from the bottom after passing through the middle pouring pipe and the soup channel in the downward pouring smelting process and enters the ingot mould, so that the surface quality of steel is good. However, the refractory material for the middle pouring pipe and the runner is directly contacted with molten steel without baking, suffers from extremely high thermal stress at the initial stage of pouring, is extremely easily eroded by molten steel, and generates nonmetallic inclusions which enter the ingot mold to affect the cleanliness of the molten steel. Therefore, the runner bricks (including square tube bricks and tail bricks) are required to have excellent erosion resistance and thermal shock resistance.
Patent CN 217121718U discloses a cast steel brick for die casting, which realizes the effect of not polluting molten steel, but has the function of removing nonmetallic inclusions in the molten steel, and the combination mode of poor thermal shock stability and inlaying not only increases the labor cost in the preparation process, but also has low safety coefficient in the service process.
