Abstract

AGENTE DE CURA RÁPIDA EM PÓ, E, MÉTODO DE PULVERIZAÇÃO PARA UM MATERIAL REFRATÁRIO NÃO MODELADO. O propósito da presente invenção é melhorar, em aplicação de pulverização de um refratário monolítico, não somente a transportabilidade de um agente de aceleração de cura que deve ser adicionado por transferência pneumática para uma composição refratária, mas também à miscibilidade do agente com a composição refratária. A presente invenção diz respeito a um agente de aceleração de cura em pó que deve ser usado em aplicação de pulverização de um refratário e que deve ser adicionado por transferência pneumática tanto em um bocal (13) quanto no agente d e aceleração de cura em pó no lado à montante do bocal (13) em uma composição refratária que é pneumaticamente transferida para o bocal (13) através de um tubo (17). Este agente de aceleração de cura em pó é caracterizado em que: o agente de aceleração de cura em pó compreende um primeiro material em pó que pode endurecer a composição refratária e um segundo material em pó que é uma matéria-prima refratária; e o segundo material em pó contém pelo menos 5 % em massa de partículas com diâmetros superiores a 0,5 mm e pelo menos 30 % em massa de partículas com diâmetros de 0,1 mm ou mais.POWDER FAST CURING AGENT AND SPRAY METHOD FOR AN UNMODELING REFRACTORY MATERIAL. The purpose of the present invention is to improve, in spray application of a monolithic refractory, not only the transportability of a cure accelerating agent that must be added by pneumatic transfer to a refractory composition, but also the miscibility of the agent with the refractory composition. . The present invention relates to a powdered curing accelerating agent which is to be used in a spray application of a refractory and which is to be added by pneumatic transfer both to a nozzle (13) and to the powdered curing accelerating agent in the upstream side of the nozzle (13) into a refractory composition which is pneumatically transferred to the nozzle (13) through a tube (17). This powdered cure accelerator is characterized in that: the powdered cure accelerator comprises a first powder material which can harden the refractory composition and a second powder material which is a refractory raw material; and the second powdered material contains at least 5% by mass of particles with diameters greater than 0.5 mm and at least 30% by mass of particles with diameters of 0.1 mm or greater.
