Abstract

MÉTODO PARA INFLUENCIAR A COMPOSIÇçO QUÍMICA DE METAL FUNDIDO DENTRO DA CAÇAMBA, E INSTALAÇçO DE EQUIPAMENTOS PARA SUA REALIZAÇçO. A invenção refere-se à metalurgia ferrosa, e mais exatamente à fabricação de aço. O método sugere passar a corrente de aço vazada a partir do câmara de fusão para dentro da caçamba dentro do canal, e no processo de tal passagem para distribuir, para dentro da corrente de metal, agentes desoxidantes e dessulfurizadores, bem como outros elementos modificadores, mudar a composição química do metal na caçamba. A distribuição é conduzida por meio de sedimentação livre com o auxilio de uma rosca e injeção de gás. Usa-se gás inativo ou inerte em todos os exemplos. A distribuição de elementos é conduzida na entrada para o canal, incluindo em várias seções ao longo do seu perimetro. A distribuição de elementos é conduzida em várias seções na altura inteira e ao longo do perímetro do canal. Sugeriu-se suceder as seções de distribuição de elementos, e no processo desta sucessão, trocar a caçamba. Os elementos são alimentados na forma de pó fino e/ou grânulos. A instalação dos equipamentos para a realização do método, além da câmara de fusão, caçamba e sistema dosado de distribuição de elementos, inclui também um mecanismo que contém um canal cujo espaço operacional é feito de material à prova de fogo, particularmente grafite, com o que, durante o processo de vazamento do metal, o mecanismo fica posicionado entre a saída da câmara de fusão e a caçamba, e depois disso, sob o posicionamento mencionado do mecanismo, o eixo geométrico longitudinal do canal e aquele da saida são coaxiais. O mecanismo possui um acionador de deslocamento ou auto-ajuste ou pode ser montado de forma imóvel, O mecanismo contém uma construção de apoio e uma peça substituivel do canal. Esta última é feita de grafite. O canal tem uma forma cônica na entrada e a parte restante é cilíndrica, com o que o ângulo da superfície cônica a partir da linha vertical compreende no máximo 30°. I11. 14.METHOD TO INFLUENCE CHEMICAL COMPOSITION OF CAST METAL WITHIN THE HOPPER, AND INSTALLATION OF EQUIPMENT FOR PERFORMANCE. The invention relates to ferrous metallurgy, and more precisely to steel fabrication. The method suggests passing the poured steel stream from the melting chamber into the hopper within the channel, and in the process of such passage to distribute deoxidizing and desulphurizing agents as well as other modifying elements into the metal stream, Change the chemical composition of the metal in the bucket. The distribution is conducted by free sedimentation with the aid of a screw and gas injection. Inactive or inert gas is used in all examples. The distribution of elements is conducted at the entrance to the channel, including in various sections along its perimeter. Element distribution is conducted in various sections at full height and along the perimeter of the channel. It was suggested to succeed the sections of distribution of elements, and in the process of this succession, to change the bucket. The elements are fed in the form of fine powder and / or granules. The installation of the equipment for carrying out the method, in addition to the melting chamber, bucket and dosed element distribution system, also includes a mechanism containing a channel whose working space is made of fireproof material, particularly graphite, with the that during the metal casting process the mechanism is positioned between the melting chamber outlet and the hopper, and thereafter, under the mentioned positioning of the mechanism, the longitudinal axis of the channel and that of the outlet are coaxial. The mechanism has a displacement or self-adjusting actuator or can be immobile mounted. The mechanism contains a support construction and a replaceable channel part. The latter is made of graphite. The channel has a conical shape at the inlet and the remaining part is cylindrical, whereby the angle of the conical surface from the vertical line comprises a maximum of 30 °. I11. 14
