The robbers, he added, had cut through the safe, using Oxygen lance
"The burglars used an oxygen lance
to open the store's safe and stole jewellery and other valuables estimated to be worth around e1/450,000.
For cooling of oxygen lance
60-70 [m.sup.3]/h water and pressure 0.7-0.9 MPa are required.
Jousting with the inferno The second part of the Sandia program opens the volcanic world inside the BOF to visual analysis via cameras built directly into the oxygen lance
that hovers just above the seething mass of molten metal.
* MMW manipulator for acceleration of the melting process and improving metal quality due to melting of metal charge in the area of the ASMF working window by gas-oxygen burner and controlled decarbonization of the melt by powerful and compact jet of oxygen (flow of oxygen in oxygen lance
is up to 3000 [m.sup.3]/h, in gas-oxygen burner of 7.3 or 10 MW power--up to 2200 m /h, flow of natural gas is up to 1100 [m.sup.3]/h) and saving of electric power due to inclusion of additional alternative power source and reduction of the furnace operation period under current;
Do not stand in front of the furnace, and under no circumstances should an oxygen lance
or burning bar be used to cut through the bridge.
In both tests, the manganese recovered from the slag after tapping had the strongest correlation to casting quality, followed by the angle of the oxygen lance
, number of heats on the ladle lining and tap rate.
Aluminum content and pinhole severity may be reduced by the use of an oxygen lance
or by plunging iron ore pellets into the melt, but, in practice, this latter technique is seldom used.
