Figure 1.

Oxygen lance tip combustion

Under this condition, any steel portion of the oxygen pipe, at Fe ignition temperature

and in contact with oxygen, will react in combustion. However, as soon as the oxygen

pipe is pulled back, the heat and oxygen bounce will end; extinguishing the Fe

combustion and usually just a few sparks will remain. Many times it is hard to keep

these sparks ignited until they reach the attack point, leaving the operator with a

difficult, non-standard, and many times unsafe procedure to ignite the oxygen pipe

(see Figure 2).

. Remaining sparks when standard lance is removed from surface

The new advanced lance ignites just like a standard steel oxygen pipe, by heating its

tip and letting oxygen pass through. However, when the tip’s combustion starts it will
