Thermal Lances are commonly used in steel mills or construction sites due to their small size and proven ability to cut thick and large pieces of scrap steel by producing a high temperature of up to 3,000 o C ~ 4,000 o C.

However, a powerful cut is not everything when it comes to the characteristics of this product. 
It can also be used for other purposes in blast furnace steelworks. Do you know everything there is to know about the applications of Thermal Lances in the Steelworks of Blast Furnace?

What is Blast Furnace?

The blast furnace, often called a BF, is a type of metallurgical furnace used in the steel mill to produce pig iron from iron ore. 

As its name suggests, the blast furnace works by blasting a combination of natural resources, including iron ore, coke, or limestone, from top to bottom, using hot air at 1,200 ^o C presionado desde ambos lados del eje vertical para calentar los materiales dentro del horno en pedazos pequeños. 

Bajo el flujo de aire caliente y la reacción química dentro del horno, se creará escoria fundida y hierro fundido y se transferirá a la fábrica de fabricación de acero para la siguiente fase de fabricación de acero.

As can be seen in the image above, the Blast Furnace operation in the course of processing materials for steelmaking involves a number of time-consuming and dangerous procedures.

practical use | Eliminate Dross in Mechanical Equipment

The buildup of solidified slag trapped in mechanical equipment such as ladle cars or pouring nozzles in continuous casting equipment after the ironmaking process is complete can deteriorate operating performance over time. In the worst case, when the equipment is damaged to the point that the repair and maintenance costs are too high, we even have to buy a new one. And this is what no one would expect to experience in the steel production process. 

To take early action against uncontrollably multiplying slag formation, we can use the thermal lances to melt the slag located in all corners of the mechanical equipment by heating one end of the Thermic Lance to a temperature above the melting point of the slag of about 1,780 ^o C.
