Abstract

resumo patente de invenção: "método de bloqueio/abertura para furo de rosqueamento, método de bloqueio e aparelho de bloqueio/abertura do mesmo". a presente invenção refere-se a um método de bloqueio/abertura de um furo de rosqueamento formado em uma parede de forno de um alto-forno, o método de bloqueio/abertura incluindo: uma etapa de bloqueio na qual um material de barro e um tampão de bloqueio formados substancialmente no formato de uma barra são pressionados dentro do furo de rosqueamento e despejados dentro do mesmo, e em seguida o material de barro é cozido para bloquear o furo de rosqueamento; e uma etapa de abertura na qual o tampão de bloqueio e o material de barro cozido são perfurados para recriar o furo de rosqueamento. o tampão de bloqueio tem uma parte que é formada para ser mais macia do que a substância cozida do material de barro de modo a se estender ao longo de todo o comprimento do mesmo. 20811897v1patent summary: "locking / opening method for tapping hole, locking method and locking / opening apparatus". The present invention relates to a locking / tapping method of a tapping hole formed in a blast furnace wall, the locking / tapping method including: a locking step in which a clay material and a locking caps formed substantially in the shape of a bar are pressed into the threading hole and poured into it, and then the clay material is baked to block the threading hole; and an opening step in which the blocking plug and baked clay material are drilled to recreate the threading hole. The blocking cap has a portion which is formed to be softer than the baked substance of the clay material to extend over the entire length thereof. 20811897v1
