Description
Практика работы доменных печей , а также снециальные исследоваНИ показали, что при нал .ичии в составе доменной шихты цинка неизбежно насыщение кладки его окислами, что часто приводит к разрыву кожухов и выходу иечей из стро . Насыщение происходит через поры кирт1ича. Отложение TiapOB пипка происходит тлавным образом в верхней части шахты, где температура не превышает 1000°. Предлагаетс огнеупорную кладку вьшолн ть ИЗ кирпича, имеюще1о менее высокие показатели огнеупорности, чем обычный доменный кирпич, и, в частности, предлагаетс кладку верхней части шахты доменных печей выпо.пн ть ИЗ кирпича, имеющего спекшийс черепок, водоноглондаюпта способность которого менее I.u.The practice of blast furnaces, as well as environmental research, has shown that when it comes to the bulk of the zinc blast mixture, saturation of the masonry with oxides is unavoidable, which often leads to rupture of the casings and the release of the blast. Saturation occurs through the pores of the kirt1ich. The deposition of the TiapOB piping occurs in the main way in the upper part of the mine, where the temperature does not exceed 1000 °. Refractory masonry from brick is less efficient than ordinary blast brick, and, in particular, brick from the upper part of the blast furnace shaft is produced from brick with a sintered shard whose water capacity is less than I.u.
В качестве сырь дл изготовлени кир-: ича со спекпшмс черепком используют тугоплавкие и камнедельные глины, беложгущиес огнеупорные глины, нреимуще ствен ,но с н.из«ой те.млературой спекани и.чи при услов ии введени плавней, и пирофиллиты.Refractory and stone-weekly clays, white-burning refractory clays, mostly made, but with ny ry tem.
Механические свойства кирпича со спекшимс черепком выше механических свойств до.меиного кирпича , вследствие чего применение кладки доменной печи из кирпича, имеющего спекпшйс черепок, резко сократит разрушительное действие окислов цинка.The mechanical properties of a brick with a speckled shard are higher than the mechanical properties of the brick of a brick, as a result of which the use of masonry of a blast furnace of a brick having a specimen shard will sharply reduce the destructive effect of zinc oxides.
