INTECO PTI’s concept has promoted the most aggressive introduction of oxygen and chemical energy into the Electric Arc Furnace (EAF) resulting in dramatic efficiency and utilization improvements. To employ this concept safely, INTECO PTI invented a unique water-cooled copper box (JetBOx™) which houses the burner and injector very low inside the EAF at a steep angle. The JetBOx^TM is designed to position the burner and oxygen injection as close to the steel bath as possible for the highest injection efficiency with no fear of damage to the EAF as it provides excellent cooling protection and is capable of withstanding the impact of falling scrap and splashing of slag and molten metal. INTECO PTI is continuously improving the design and quality of the JetBOx™ product to enhance the already long life cycle.

The JetBOxes™ are situated just above the last course of refractory bricks with their front face in line with the hot face of bricks. This location provides the following advantages for the EAF operations:

• Enables better energy transfer into the scrap in the scrap melting mode
• Minimizes plugging from splashing slag and molten metal during EAF operation
• Eliminates overheating problems in adjacent panels by moving the burner further from the panels' hot face
• Promotes higher oxygen efficiency due to shorter jet length and the ability to use the optimal injection angle
• Allows carbon and lime injection to be applied closer to the molten bath promoting better foamy slag and minimizing material losses
• Significant energy savings due to closed slag door operation

The Forged PTI Copper JetBOx has the same shape as the cast JetBOx.  However, the internal water passagesw of the forged jetbox are machined and allow direct water to copper contact.  In addition the copper is forged.  The advantage of forged metal over cast metal is that during the internal grain deforms to follow the general shape if the part and as a result, the grain is continuous through out the part resulting in improved strength and heat transfer characteristics.

The miniJetBOx^TM as its bigger brother (JetBOx^TM) is designed to position the burner and oxygen injection as close to the steel bath as possible for the highest injection efficiency with no fear of damage to the EAF. The dimensions of the miniJetBOx^TM are as follows: Height (18”, 457mm), Width (29.5”, 750 mm) Depth (16”, 405mm);

The main features and advantages of INTECO PTI’s miniJetBOx^TM are:

• Enables better energy transfer into the scrap in the scrap melting mode
• minimizes plugging from splashing slag and molten metal during EAF operation
• eliminates overheating problems in adjacent panels by moving the burner further from the panels' hot face
• promotes higher oxygen efficiency due to the shorter jet length and the ability to se the optimal injection angle
• allows carbon and lime injection to be applied closer to the molten bath promoting better foamy slag and minimizing material losses
• significant energy savings due to closed slag door operation
