Description

The casting crane is the main equipment in the steelmaking and continuous casting process, which is mainly used for charging the converter and mixing molten iron across the converter; The ladle is lifted to the refining furnace at the refining span or the ladle turret at the molten steel receiving span.

From the overall structure, the casting cranes can be divided into five categories: four beam four rail double small car, four beam six rail double small car, double beam double rail single small car, double beam four rail double small car, double beam double rail sub small car.

According to the structural form of the main lifting reducer, the composition of the casting crane is mainly divided into the overall large reduction type, the independent large reduction type, the three reduction type, the double reducer double drum type, the double reducer single drum type, and the planetary reducer type (these types can also be divided into various forms).

Application

Steel plant casting cranes are essential in the heavy-duty tasks of moving molten steel, heavy castings, and other high-temperature materials in steel production environments. These cranes are specifically designed for the harsh conditions found in steel plants, where high heat and heavy loads are common. They are ideal for tasks such as lifting steel ingots, ladles, and billets, as well as transporting finished products between different stages of production.
