Изобретение относитс  к способам защиты огнеупорных материалов от разрушени  силикатными расплавами и может быть использован на заводах силикатной промышленности, в частности дл  увеличени  срока службы огнеупорной кладки стекловаренных печей.The invention relates to methods for protecting refractory materials from destruction by silicate melts and can be used in the plants of the silicate industry, in particular to increase the service life of the refractory masonry of glass melting furnaces.

Известен способ защиты металлических нагревательных электродов плавильных печей, работак  их на посто нном токе, против испускани  ионов, в частности катионов, которые содержатс  в силикатной массе, при этом положительный полюс источника посто нного тока присоединен к нагревательным электродам и отрицательный полюс к вспомогательному электроду 11.A known method of protecting metal heating electrodes of melting furnaces, operating them on direct current, against the emission of ions, in particular cations, which are contained in the silicate mass, with the positive pole of the direct current source attached to the heating electrodes and the negative pole to the auxiliary electrode 11.

Недостатком этого способа  вл етс  то, что он не может быть применен дл  защиты огнеупорных материалов стекловаренных печей.The disadvantage of this method is that it cannot be used to protect the refractory materials of glass melting furnaces.

Наиболее близким по технической сущности и достигаемому эффекту  вл етс  способ за;диты огнеупорных материалов , в частности шамотных, от коррозии под воздействием силикатного расплава с помощью вспомогательных электродов в расплаве и провод щих элементов на поверхности огнеупорного материала, соединенных с проти2The closest in technical essence and the achieved effect is the method for refractory materials, in particular fireclay materials, from corrosion under the influence of silicate melt with the help of auxiliary electrodes in the melt and conductive elements on the surface of the refractory material connected to

вопаложными полюсами источника посто нного тока под воздействием ЭДС, характеризуетс  тем, что провод щие элементы ввод тс  в переходное глазурное покрытие на огнеупорном материгше и ЭДС регулируетс  таким образом, чтобы плотность тока на поверхности контакта расплава с огнеупорным материалом была менее 1 мА/см этой по10 верхности 2 .The poles of the DC source under the influence of EMF are characterized by the fact that the conductive elements are introduced into the transition glaze coating on the refractory material and the EMF is adjusted so that the current density on the surface of the melt contact with the refractory material is less than 1 mA / cm surface 2.

Недостатком указанного способа  вл етс  то, что защита огнеупорного материала основана на использовании электролитического процесса, протекакхцего В области контакта расплаг .а с огнеупорным материалом, при этом электрический зар д на поверхности огнеупорного материала не снимаетс , что снижает эффективность згшиты огне20 упорного материала от силикатного расплава и уменьшает срок его службы.The disadvantage of this method is that the protection of the refractory material is based on the use of an electrolytic process that proceeds to the area of contact between the raspand and the refractory material, while the electric charge on the surface of the refractory material is not removed, which reduces the efficiency of refractory material refractory material from silicate melt and reduces its service life.

Целью изобретени   вл етс  увеличение срока службы огнеупорной- кладки за счет сн ти  электрического зар да The aim of the invention is to increase the service life of the refractory masonry by removing electrical charge.
