Изобретение относитс к области черной металлургии , в частности к составу масс дл кладки футеровки мартеновской печи.This invention relates to the field of ferrous metallurgy, in particular, to the composition of masses for laying the lining of an open-hearth furnace.
Известен мертель дл кладки основной футеровки мартеновской печи, содержащий магнезитовый порошок и окалину, в котором компоненты вз ты в следующем соотношении, вес. %:A mortar is known for laying the main lining of an open-hearth furnace containing magnesite powder and scale, in which the components are taken in the following ratio, weight. %:

то, что при разогреве кладки мертель вытекает из швов, что св зано с низкой температурой разм гчени смеси. В результате этого не достигаетс получение монолитной футеровки. С целью повышени монолитности огнеупорной кладки в состав предлагаемого мертел введен шлак из щлаковиков мартеновской печи при весовом соотношении окалины к шлаку 1:3. При этом компоненты мертел вз ты в следующем соотношении, вес. % The fact that during the warming up of the masonry the mortar flows out of the seams, which is associated with a low softening temperature of the mixture. As a result, a monolithic lining is not achieved. In order to increase the solidity of the refractory masonry, slag from the slag stones of an open-hearth furnace with a weight ratio of scale to slag of 1: 3 is introduced into the composition of the proposed mortar. At the same time, components are dead taken in the following ratio, weight. %
