UTILIZATION OF ALLOY STEEL WASTES
IN ONE USSR STEEL PLANT
Stal', Vol X, No 2, Feb 40
Ia the drive for improved consumption coefficientF, the Zaporozh'ye Elec-
trometallurgical Plant is ma;r_ing extensive use of the method of resmelting waste
products in the production of a number;lof structural steels containing more then
0.25 percent carbon. The following resmelting methods are being used:
1, Otte hundred-percent resmelting of chrome-nickel and chrome-molybdenum
waste products in acid electric fin~naces; this method is called the chrome-recov-
ery process with diffusion deoxidation;
2. Resmelting without oxidation of chrome-nickel waste products is basic
furnaces; the charge consists of 70 percent waste products and 30 percent soft
iron;
3> Resmelting of chrome-molybdenum-aluminum waste products under alumina
slags ?.:~thout ..xi,Aatioa.
The quality of the steels smelted by these methods is almost as high as the
quality of the steels made from the fresh charge.

The Zaporozh'ye Electrometallurgical Plant, in testing methods of smelting
chrome-nickel steel from chrome-nickel waste products, found the duplex process
the moat successful, It was proposed to smelt the chrome-nickel waste products
i.n two furnaces: an acid furnace in which a charge of~100-percent chrome-nickel
waste products was smelted and decarbonized under chrome-reduction conditions,
and a basic furnace with refining under white lime slags. This duplex-process
.method was used in the production of chrome-nickel and chrome-nickel-tungsten
steels slated for important uses.

The experimental melts proved the value of this method. The steel was iden-
tical in quality to the chrome-nickel structural steel made in basic electric
furnaces and the coefficients for consumption of nickel, tungsten, and chromium
were reduced. The plant has begun mass production according to this method.
This process is most valuable in the use of medium-carbon chrome-nickel and mild
chrome-nickel-tungsten' waste products in smelting low-carbon chrome-nickel and
chrome-nickel-tungsten steels,
Stal,!, Vol X, No 8, Aug 40
The Moscow "Sere i molot" Plant has made three test melts of resmelting
,light-weight war,t~ products (sheet clippings and billet cuttings) of stainless
steel (18 percent Cr, 8 percent Ni) in a basic open-hearth furnace. The melts
showed the full possibility of resmelting 100 percent of -the high-chromium-
nickel waste products in a basic 25-ton open-hearth furnace with a 20-22-ton
charge. Losses of chromium during the sme'ting period amount to only 10-15
percent. Only a small quantity of chromium is added during smelting. The total
length of the melt is no longer than the length of a melt of quality alloy steel.
The innovation enables the plant to utilize light-weight alloy wastes which be-
cause of size and weight could not be used in electric furnaces.
