2. According to the air temperature, it can be divided into two types of hot iron ladle and cold iron ladle
3. According to the furnace shape of the molten iron ladle, it can be divided into two different types of molten iron ladle: straight furnace ladle and curved furnace ladle. The inner wall of the molten iron ladle in the curved furnace is curved, and the diameter of the furnace wall changes with the height of the furnace; The inner wall of the molten iron ladle in a straight furnace is straight and straight
4. According to the size of the tuyere of the ladle, the tuyere ratio is the ratio of the total area of the tuyere outlet to the sectional area of the furnace at the main tuyere
5. According to the way of ladle air supply, it can be divided into three different types of ladle: side air supply, bottom air supply (also called central air supply), and the combination of side and central air supply. The bottom air supply is supplied by the air section installed at the bottom of the ladle furnace, and the combustion area is concentrated in the middle of the ladle; The air supply outlet for side air supply is arranged around the bellows, and the air is supplied at the side, and the combustion area is near the furnace wall; The combination of side blowing and central air supply can make the furnace air supply uniform
6. According to the chemical composition of furnace lining materials, it can be divided into three kinds of molten iron ladle: alkaline molten iron ladle, acidic molten iron ladle and neutral molten iron ladle. The lining of the alkaline ladle is made of alkaline refractory; Acid ladle refers to the furnace lining made of acid refractory material; The furnace tree of the neutral ladle is built with neutral refractory< br/>
