The achievements of NPP Vulkan-TM in the production of basic forms of production (slide gates, vibra
tion-molded refractories, ceramics, systems for blowing metal with argon, etc.) are analyzed. Specific atten
tion is devoted to the development and introduction of a new slide gate VTM-50V, the results of testing the life
of plates of Russian and overseas production within a new generation of slide gates, and also vibration-cast
high-alumina refractories within a set of refractories for slide gates of the VTM series.

In NPP Vulkan-TM since 1997 together with leading re-
fractory enterprises of the Russian Federation (ZAO
Rosogneupor, OOO Gruppa Magnesit, OAO Kombinat
Magnesit, OAO Semiluk Refactory Plant (AOA SOZ), OOO
Ogneupor-complekt) there has been complete supply of
modern system of stopperless steel pouring for ladles with a
capacity of 2 – 200 tons and refractories for them.
Concerning conditions for pouring steel in continuous
billet casting machines (CBCM), the ladles used and the
standard sizes of refractory plates, recently NPP Vulkan-TM
has developed and introduced into series production a new gen
eration of slide gates of the magazine type models VTM-60-80
(for 130 – 300-ton ladles), VTM-50 (for 50 – 150-ton la
dles), and VTM-30 (for a ladle capacity of 30 tins).
Currently NPP Vulkan-TM is continuing introduction of
single-spring controlled gates VTM-50B for pouring steel in
CBCM. The gates have already been introduced into the
ESSW of such enterprises as ZAO OMZ (Omutinsk), ZAO
NSMMZ (Redva), OAO metallurgical Plant Élektrostal’
(Élektrostal’), OAO Novorosmetall (Novorossisk), ZAO
Azov Élektrostal’ (Mariupol), and in a number of others. Re
cently the construction of slide gate grade VTM-50V (Fig. 1)
has been developed.
The slide gates VTM-50V proposed are a development
of gates of the VTM series (used in more than ten enterprises
of the RF and the CIS), and their construction is adapted for
the production conditions of pouring steel in CBCM. The
main advantages of these gates relate to:
– the original structural layout of the clamping of refrac-
tory plates, using a modular construction, making it possible
to realize different layouts of the gate device on a ladle;
– the increased life of spring assemblies (300 melts), the
possibility of checking springs and control without removing
them from the gate (Fig. 2);
– adaptation of gate construction for steel-pouring con
ditions in CBCM (reduction in gate height, the possibility of
reducing the height of the steel-pouring channel, increased
life of friction pairs);
– possibility of servicing a slide gate both in a semi-au
tomatic regime using a hydraulic drive, and also in a manual
regime in vertical and horizontal stands for ladle servicing.
Gates of this grade have been proved successfully in the
KSP-steel Metallurgical Combine (Pavlodar,
Kazakhstan) together with refractories produced by
Dalmond (PRC). On the basis of gate VTM-50 a construc
tion has been developed for highly loaded (grade
VTM-60/80) and small ladles (VTM-30M).
Experience of operating modern slide systems of the
VTM series has shown that the elastic elements, within their
composition, did not exhibit the required life and reliability
as a result of the fact that they were not manufactured from
heat-resistant materials, but from spring steels according to
standard technology. This gave rise to the need to carry out a
series of theoretical and experimental studies with the aim of
developing special technology for producing heat-resistant
elastic elements. As a result of this springs prepared by the
