Abstract:
Quality of steel ladles lining to a big extent determine the economic efficiency of steel-making operation. Direct costs on the refractory lining of them can reach 30–50 % of the costs of lining of a steel-making complex. Experience of utilization of refractory materials of different composition considered with the purpose of efficiency increase of refractory materials application in the steel ladles lining under conditions of steel ladle treatment. Considerable abilities shown to make the lining of steel ladle walls and bottom by both carbon-containing and carbon-free refractory materials tak

The problem of tightening of outlet channel of steel ladle still remains relevant at present. A review of scientific and technical studies, aimed at elaboration of methods to keep the channel flow section constant presented. An analysis of deposition forming mechanisms on walls of outlet channel of steel ladle was done. To prevent their formation it was proposed to apply a vibration impact on the ladle shutter. Using simulation studies and specially elaborated methodology, the degree of influence and frequency of amplitude oscillations, acting along the ladle channel, on increasing speed of la

O aumento da demanda por aços cada vez mais exigentes, em termos de composição química e limpidez interna, faz com que as condições de refino nas aciarias sejam cada vez mais severas. Ao mesmo tempo, o aumento dos tempos de tratamento do aço, aliado às outras variáveis operacionais como quantidades e tipos de adições químicas, etc. fazem com que haja um aumento no tempo de contato entre o revestimento refratário das panelas de transporte de aço e escórias com conseqüente redução do desempenho (vida) de tais revestimentos refratários.

Abstract:
In present thesis, the fundamental studies on the reaction between MgO based refractories and slag were undertaken for the development of a carbon-free bonding MgO lining material. Alumina was selected as a potential binder material. Due to MgO-Al2O3 chemical reaction, the developed refractory was bonded by MgO·Al2O3 spinel phase. To begin with, an investigation of the dissolution process of dense MgO and MgO·Al2O3 spinel in liquid slag was carried out. To obtain reliable information for dissolution study, a new experimental method was therefore developed. In this method, a cylinder was rotati

Para atender os altos níveis de produção exigidos dos Altos Fornos, a disponibilidade dos Canais de Corrida e dos Carros Torpedo torna-se um fator estratégico. Dentre as propostas de manutenção e reparo disponíveis pela indústria de refratários, a utilização de concretos refratários bombeáveis desponta como um recurso que possibilita, sinergicamente, realizar o reparo de forma localizada e em curtos tempos de parada. Utilizando esse tipo de material, existem, basicamente, dois tipos de aplicação: a realizada por \"Gunning\" e por \"Shotcrete\", cuja principal distinção para o usuário ocorre em
