Monolithic lining of ladles for out-of-furnace treatment of steels

Conclusions We studied the effect of the additives (silicon carbide, boron nitride, and chromite) on the physical and mechanical properties of a high-alumina ramming body, It was established that chromite additions significantly improve the properties of the body.The optimum composition of the high-alumina body based on the ÉB-50 electrocorundum (73%) and the ShMK-77,5 mullite-corundum chamotte (27.0%) containing 10% chromite additive was developed using orthophosphoric acid as a binder. The body has the following properties: apparent density 2.4 g/cm³; open porosity 23.8%; and the ultimate compressive strength 135.5 N/mm².The developed body composition is recommended for preparing rammed lining of the ladles used for the vacuum treatment of steels.Translated from Ogneupory, No. 3, pp. 5–7, March, 1988.     

Effect of Thinning Agents on Properties of High-Alumina Ceramic Castables

The effect of thinning agents on molding mixtures for the production of high-alumina ceramic castables composed of bauxite HCBS (highly concentrated ceramic binding suspensions) and a refractory filler based on fused corundum and SiC is studied. The thinners used were sodium tripolyphosphate (STPP), SB-5-grade organic plasticizer, mixtures thereof, and liquid glass. The maximum thinning effect is observed for complex organomineral additives (10 – 33% SB-5 + 67 – 90% STPP). The optimum thinner concentration is 0.08 – 0.1 wt.%. The use of thinners makes it possible to reduce significantly the water demand of concrete mixes and leads to a decrease in porosity and an increase in strength of ceramic castables. The composition and concentration of alkali-containing thinners produce little (if any) effect on the deformation behavior of ceramic castables at high temperatures.     

Measuring the plasticity of clays: A review

Plasticity is the outstanding property of clay–water systems. It is the property a substance has when deformed continuously under a finite force. When the force is removed or reduced, the shape is maintained. Mineralogical composition, particle size distribution, organic substances and additives can affect the plasticity of clays. Several measuring techniques and devices were proposed to determine the optimal water content in a clay body required to allow this body to be plastically deformed by shaping. In this review, methods of evaluating the plasticity of clay–water systems are presented. Despite the advance in the theory of the plasticity and the methods of measurement, a common procedure for all types of materials does not exist. The most important methods are those that simulate the conditions of real processing.
