The main ways of reducing expenditure for steel pouring are considered, i.e. import substitution and the opti
mum frequency of using plates for slide gates. Technical and economic analysis is provided for the use of re
fractory objects in steel-pouring systems produced by OOO NPP Vulkan-TM.
Keywords: slide gate refractories, unified slide gates, steel pouring using slide gates, steel-pouring systems,
Under conditions of an increasing economic crisis a
guarantee for the survival of Russian metallurgical enter-
prises is the possibility of a considerable reduction in pro-
duction delays. The scientific and production enterprise
Vulkan-TM proposes a reduction in losses in steel smelting
and to reduce the import dependence of domestic enterprises
by use of steel-pouring slide systems of the VTM series and
refractories consumed by them. Here with a reduction in re-
fractory consumption, the content and restoration of the
stock of slide gates, ladle logistics are optimized with a re
duction in energy consumed in warming up ladles and an in
crease in lining life, and the accident rate is reduced.
The structure of expenditure is presented in Fig. 1 di
rectly for steel pouring refractories, from which a definitive
role of plates for slide gate plates is evident.
Currently NPP Vulkan-TM in order to optimize expendi
ture has developed and introduced into series production a
range of unified sliding system constructions of the VTM se
ries, and corresponding to them, sets of consumable refrac
tory objects, and they have been supplied to more than ten
enterprises of the Russian Federation and CIS.
Gates of the VTM series (Fig. 2) have been adapted for
production conditions of contemporary electric steel smelt
ing and converter production. Slide gates within the frame
work of a single size may have small structural differences in
relation to operating conditions, refractory sets have been
unified to a maximum, and they may only differ in the con-
struction of the nesting block and delivery part of the noz-
zle-collector in relation to the presence and type of protective
Within the composition of a typical set of VTM refrac-
tories there are:
1. Plates for the slide gate in a shroud prepared from
fired billets of plates form the leading overseas producers.
Refractories are selected in relation to the specific steel pour-
ing conditions, that makes it possible to add to their optimum
life. Supply is offered to customers of plates of periclase
(1 – 2 melts), corundum-carbon (2 – 4 melts) and periclase-
carbon (1 – 2 melts) compositions. Calculations and operat
