Contemporary systems are considered for pouring metal from a ladle using unified double-plate slide gates of
the BTM series produced by OOO NPP Vulkan-TM and sets of refractories appropriate for them. Attention is
drawn to the use of these systems in small metallurgical enterprises. Experience is considered of operating
slide refractory plates of domestic and imported production. A method is proposed for manufacturing refrac
tory components for slide gates by casting with subsequent vibration levelling. A device is considered for
blowing metal in a ladle with inert gas, improving its quality.
Alongside contemporary large metallurgical combines
there are a large number of engineering enterprises with dif-
ferent profiles within whose structure there are small metal-
lurgical plants and production. A typical feature of them is
the relatively ageing equipment, lack of extra-furnace metal
processing, pouring of metal from teapot ladles, or in some
cases by means of a stopper mechanism, that affect metal
quality and its cost.
The modern tendency of metallurgical production is fini
shing and processing of metal in a ladle after melting or
melting followed by pouring from a ladle with a slide gate.
Slide gates are being used more extensively since they make
it possible to improve considerably the level of automation
of the pouring process; to accelerate ladle turnover, shorten
ing their servicing time; to increase the accuracy of dispens
ing metal with the possibility of changing the size of portions
within the limits of a single melt; to reduce unplanned metal
loss. Slide gates are ergonomically inserted into a pouring
system for metal from ladles.
Currently slide gates are known from a number of over
seas firms such as Vesuvius (Belgium – USA), Voest-Alpine
(Austria), Interstop, Stopinc AG (Switzerland, Didier-Werke
(Germany), International Industrial Engineering (Belgium),
Shinigawa Refractories (Japan), Flogates (Great Britain), etc.
Undoubtedly, slide gates of overseas firms exhibit a number
of advantages, although their cost and refractories for them
significantly exceed the cost of domestic analogs; the cum
bersome nature of structures and refractories, the servicing
specifics and training of personnel also markedly hinder
mass application of imported slide gates.
There is competition with overseas firms in the domestic
market by Russian firms specializing in producing sliding
systems and refractories for them. This relates to the firms
OOO NPP Vulkan-TM, Tula, and ZAO Shiber, Moscow.
The firm OOO NPP Vulkan-TM from 1997 to present
time has developed a range of unified two-plate slide gates of
the VTM series (Table 1) and appropriate sets of refractory
components for them in metal shells and straps.
Considering the stringent requirements laid down for
slide gates during pouring of steel into CICM, in recent years
OOO NPP Vulkan-TM has developed and introduced into se
ries production a new generation of slide gates of the magazine
type VTM 60 – 80 (ladles with a capacity of 150 – 300 tons),
VTM-50 (ladle capacity 50 – 150 tons), and VTM-30 (ladles
with a capacity of up to 30 tons). The structural solutions
used have been proven and operated in series production
