A method for continuous casting tundish improve the success rate of heat exchange

A method for improving the heat exchange caster tundish success rate provided by the invention, 1) Preparation of molten packet time 5-10min, internet casting ladle reaches a temperature of 1590-1600 ℃; 2) measuring, when the height 300-500mm , the tundish car start, the red-hot immersion nozzle connection, to ensure the distance from the upper opening of the bottom mold nozzle is 150-180mm; 3) after 10 tons of steel to the casting ladle, the tundish cover 150-200kg agent is added, which open pouring temperature> 1550 ℃; 4) when the ladle is poured 20 tons of steel, pouring tundish, the tundish injecting water into the mold; 5) casting speed, the casting speed is over 8min reduced to 0.3m / min, retention 1min and then added to the normal casting speed 0.9m / min, the first stop pouring tundish from the tundish to the second start time is controlled within 5min.
