Molten steel ladle injection mold formed by Sheng ingot solidification. The liquid steel smelting in blast furnace complete, must cast ingot or billet shape can be processed. With a die cast ingot casting process is referred to as.
Ingot casting points on the casting (Figure 2) and the lower casting (Figure 3) two. On the internal structure of cast ingot is generally good, few inclusions, operation cost is low; the next cast ingot surface quality is good, but because of the injection pipe and soup made of inclusions in steel to increase.
Ingot size depends on many factors, such as steel-making furnace capacity, blooming billet, steel dimensions and steel properties. For the production of bar and section steel ingot is generally Affirmative section (called Fang Ding); production sheet ingot is generally rectangular section (known as the flat ingot); production forging material ingot with a square, round and polygon.
Casting temperature is too low, the liquid steel into the mold after surface immediately solidification, will cause the ingot surface defect, even the molten steel in the ladle is began to solidify, resulting in loss of metal or the whole furnace steel scrap; casting temperature is too high, will delay the formation time of steel ingot, lead ingot thermal crack.
On killed steel, casting temperature control in general higher than the liquidus temperature of the steel 40 ~ 60 ℃. In order to ensure uniform whole barrel temperature of molten steel, to ladle argon stirring in liquid steel. In order to ensure uniform whole barrel temperature of molten steel, to ladle argon stirring in liquid steel. Injection speed casting method generally requires proper injection speed to ensure the liquid steel in mold rises smoothly, and adjusting the cas
