Description
Известна огнеупорна обмазка дл кирпичей из основных огнеупорных материалов (магнезитовых, хромомагнезитовых, магнезитохромитовых и др.), используемых дл кладки стен печей, включающа кварцевый песок и сверх 100%, воду или сульфидно-целлюлозный экстракт дл затворени .Known refractory coating for bricks of the main refractory materials (magnesite, chromium-magnesite, magnesite-chromite, etc.) used for masonry furnace walls, including silica sand and in excess of 100%, water or sulphide-cellulose extract for mixing.
Цель изобретени - повысить прочность футеровки .The purpose of the invention is to increase the strength of the lining.
Это достигаетс тем, что она содержит (в вес. %): кварцевый песок 45-50 и, кроме того, огнеупорную пластичную глину 50-55.This is achieved by the fact that it contains (in wt.%): Quartz sand 45-50 and, in addition, refractory plastic clay 50-55.
Слой описываемой обмазки сметанообразной консистенции нанос т а грани кирпича перед укладкой их в стены.A layer of the described plastering of a creamy consistency is applied to the edges of the brick before laying them into the walls.
В процессе работы при температурах сталеварени в результате химического взаимодействи полукислой массы и основного кирпича кирпичи спекаютс в цельный прочный монолит , хорошо выдерживающий механическиеIn the process of operation, at temperatures of steelmaking, as a result of the chemical interaction of the semi-acid mass and the main brick, the bricks are sintered into a solid solid monolith that can well withstand mechanical
воздействи в процессе загрузки печей и обладающий высокой химической и термической стойкостью и огнеупорностью.impact during furnace loading and possessing high chemical and thermal resistance and fire resistance.
При эксплуатации така футеровка не скалываетс , ,не оплавл етс и хорошо противостоит агрессивности шлаков и печных газов. Стойкость стен возрастает в 2-4 раза, резко снижаютс простои печей на смене и ремонте футеровки.During operation, such lining does not cleave, does not melt, and well resists the aggressiveness of slags and furnace gases. The durability of the walls increases by 2-4 times, and the stopping time of furnaces for changing and repairing lining decreases sharply.
