Description

Водоохлаждаемые своды сталеплавильных и ферросплавных печей, несмотр  на защиту их рабочей поверхности слоем огнеупорной массы , не выдерживают длительной эксплуатации и разрушаютс . Малый срок службы сводов приводит к большим трудовым затратам, повышенному расходу огнеупоров и снижению производительности печейДл  увеличени  срока службы свода используют футеровочную массу из хромомагнезитового порошка на св зке из жидкого стекла, кремнефтористого натри  и огнеупорной глины, обладаюш,ую высокой огнеупорностью и хорошо выдерживающую тепловые удары и резкие колебани  температуры.Water-cooled arches of steel-smelting and ferroalloy furnaces, despite the protection of their working surface with a layer of refractory mass, do not withstand long-term operation and are destroyed. The short service life of the vaults leads to high labor costs, increased refractory consumption and reduced furnace performance. To increase the service life of the vault, a lining mass of chromo-magnesite powder on a bond of liquid glass, sodium silicofluoride and refractory clay is used, which is highly refractory and well resistant to thermal shock and sharp temperature fluctuations.

Основу массы составл ет хромомагнезитовый порошок следующего гранулометрического состава (в %):The basis of the mass is a chromo-magnesite powder of the following granulometric composition (in%):

зерна крупностью от 10 мм - 50,grain size from 10 mm - 50,

К такому порошку добавл ют (в %):To this powder is added (in%):

кремнефтористого натри -1--3;silicon fluoride sodium -1--3;

жидкого стекла-7-10;liquid glass-7-10;

огнеупорной глины-5-6.refractory clay-5-6.

После нанесени  сло  такой массы на поверхность свода производ т ее постепенное нагревание, в рсзул,тате чего масса тер ет воду, а при температуре более 700° начинаетс  спекапие материала свода в монолит .After applying a layer of such a mass on the surface of the roof, it is gradually heated, in a crush, the mass of which loses water, and at a temperature of more than 700 ° C, the material of the arch is monolithic.

Предмет изобретени Subject invention

Свод сталеплавильных и ферросплавных печей, выполненный в виде полой водоохлаждаемой конструкции, футерованной со стоооны рабочего пространства печи огнеупорной массой, отличающийс  тем.A set of steelmaking and ferroalloy furnaces, made in the form of a hollow water-cooled structure, lined with stools of working space of the furnace with a refractory mass, characterized by that.

от 0,088 до 2 - 4 .мж - 15, от О, до 0,088 мм - 35. from 0.088 to 2 - 4 .mzh - 15, from O, to 0.088 mm - 35.

№ 137124- 2 -No. 137124- 2 -

что, с целью увеличени  срока службы свода, в состав массы ввод т хромомагнезитового порошка 100% и сверх этого кремнефтористого натри  1-3%, жидкого стекла - 7-70% и огнеупорной глины - 5-6%.that, in order to increase the service life of the vault, chromo-magnesite powder 100% is introduced into the composition of the mass and 1-3% over and above this silicofluoride sodium, 7-70% liquid glass and 5-6% refractory clay.
