Description

Известен способ изготовлени  крупногабаритных угольных и графитированных блоков и изделий сложной конфигурации методом прессовани  из электродной массы с последующим обжигом и графитацией. Недостатком этого способа  вл етс  его сложность.A known method of manufacturing large-sized coal and graphitized blocks and products of complex configuration by pressing from an electrode paste, followed by firing and graphitization. The disadvantage of this method is its complexity.

Предлагаемый способ более прост и обеспечивает получение плотного , прочного и термостабильного шва между детал ми изделий.The proposed method is simpler and provides a tight, durable, and thermostable seam between the parts of the products.

Особенность способа состоит в том, что части блоков и изделий соедин ют резольной графитонаполненной фенолоформальдегидной замазкой с последующим обжигом их известным путем в восстановительной среде.The peculiarity of the method is that parts of the blocks and products are connected with a rezol graphite-filled phenol-formaldehyde putty, followed by firing in a known way in a reducing environment.

Способ осуществл ют следующим образом.The method is carried out as follows.

Части крупногабаритных угольных и графитированных блоков и изделий сложной конфигурации соедин ют клеем следующего состава в процентах:Parts of large-sized coal and graphitized blocks and products of complex configuration are connected with an adhesive of the following composition in percent:

Резольна  смола с в зкостью 10-20°Э при 35° и содержанием влаги и фенола не более 2%-65.Resole resin with a viscosity of 10–20 ° E at 35 ° and a moisture and phenol content not exceeding 2% –65.

Кислый отвердитель, например парахлорбензолсульфокислота - 2,5.Acid hardener, for example parachlorobenzenesulfonic acid - 2.5.

Активатор, например дибензотиозолидисульфид-1,5.An activator, for example, dibenzothiozolidisulfide-1.5.

Искусственный графит в виде порощка - 31.Artificial graphite in the form of powder - 31.

Склеенные между собою детали отверждаютс  при 15-20° в течение 20-30 мин., затем при 85-95° в течение 5 час. и при 120-130 в течение 2-3 час.The parts glued together are hardening at 15-20 ° for 20-30 minutes, then at 85-95 ° for 5 hours. and at 120-130 for 2-3 hours.

После отверждени  склеенные детали подвергаютс  обжигу в углеродистой засыпке при 1300° в течение 350-420 часСпособ изготовлени  крупногабаритных угольных и графитированных блоков и изделий сложной конфигурации, отличающийс  тем. Предмет изобретени After curing, the glued parts are fired in carbon bed at 1300 ° for 350-420 hours. A method of manufacturing large-sized coal and graphite blocks and products of complex configuration, characterized in that. Subject invention

№ 116653- 2 -No. 116653-2 -

что, с целью достижени  плотного, прочного, термоотабильного шва, части блоков и изделий соедин ют резольной графитонаполненной фенолоформальдегидной замазкой с последующим обжигом их известным способом в восстановительной среде.that, in order to achieve a dense, durable, thermostable seam, parts of the blocks and products are connected with a rezol graphite-filled phenol-formaldehyde putty, followed by firing in a known manner in a reducing environment.
