At present domestic and foreign steel plants are adopting repair of the working layer of the combined lining of steel teeming ladles by the method of additon of fluid concrete mixtures,In a monolithic cast lining [2] the working layer, as a rule, wears to the indicators [3] and is constantly being repaired by addition.As for guniting addition is done after cleaning the working surface of the lining of the skull of slag and metal without breaking up the remainder of the working layer refractory [4]. In contrast to guniting in addition losses of lining materials in the form of rebound, sliding off, and falling off are not formed and the design thickness of the working layer and of the whole lining is restored with the maximum accuracy.In connection with this it is desirable to characterize the length of the campaign and to evaluate the life of the lining by the number of heats teemed from the ladle with the added layer of concrete.For addition and pouring of the lining a built-up template with an unchanging volume [5] built for manual ramming of the lining [6] is used.Under the influence of the forces of molecular cohesion and surface tension of the waterglass in the capillaries in the cast lining the rule of preservation of the minimum surface energy of the system is realized.As the result of the action of this rule the layer of fluid concrete, contracting during air shrinkage and hardening, presses tightly against the template [7] and forms the gap GI ( Fig. la) with the lining of the walls or the ladle housing.The forces of cohesion with the template exceed the forces of its cohesion with the lining or the shell of the ladle, as the result of which in the layer of added and cast concrete tensil stresses occur in raising of the template.Since the tensile strength of the concrete is 0.06-0.11% of its compressive strength and template, raised upward strictly vertically, frequently ruptures the cast and specially the thinner added layer of concrete at one or more points and reduces its life.With an increase in the consumption of lumps of used concrete [8] and a decrease in the moisture content and thickness of the layer of fresh concrete the air shrinkage of it decreases and the cohesive strength with the lining of the walls and the ladle shell increases. Organic and mineral lubricants applied to the surface of the template and its removal from the ladle in individual sections in turn weakens the forces of cohesion of the concrete with the template.However, as the result of the different rate, length, and successive character of the hardening process the mechanical strength of the concrete across the thickness and height of the lining and its cohesive forces with the template are different and therefore the above measures are insufficiently effective to reliably and constantly provide removal of the template from the ladle without sharp jerks and damage to the layer of concrete.In our combine to prepare and repair ladle monolithic linings there has been developed and tested a template with a controllable volume [...
