Technical Field

The invention relates to the technical field of modification of pig iron casting equipment, in particular to a monitoring type heating device of a pig iron casting box.

Background

The pig iron is an iron-carbon alloy with the carbon content of more than 2 percent, the carbon content of industrial pig iron is generally 2.11 percent to 4.3 percent, and the pig iron contains elements such as C, Si, Mn, S, P and the like, and is a product smelted by iron ore through a blast furnace; according to the different forms of carbon in pig iron, it can be divided into steel-making pig iron, cast pig iron and nodular cast iron.

In the process of pig iron processing production, as pig iron needs to be heated at a certain temperature, a continuous heating or constant temperature condition and environment are needed, a plurality of heating devices cannot rapidly heat the pig iron, and the temperature needs to be observed and regulated manually, so that a great amount of time and labor power are wasted; chinese patent publication No. CN204122705U proposes a monitoring heating device for pig iron casting box, which through temperature sensor and serpentine heating rod, carries out temperature monitoring and heating temperature rise control in the box, conveniently guarantees good processing temperature environment in the box, but because it is fixed point heating, and the air is in the state of relative rest in the box, when heating, temperature stratification phenomenon appears very easily, the temperature is uneven in different positions in the box, can influence the actual casting processing effect.
