Description

Регулировку нагрева образцов производ т по температуре с равномерным нагревом изделий до 60°С в течение 30 мин при переключении направлени  постО)1нного тока через каждые 10 сек с помощью автоматического переключени .The heating of the samples is adjusted according to the temperature with uniform heating of the products up to 60 ° C for 30 minutes when switching the direction of the postO 1 nn current every 10 seconds using automatic switching.

Напр жение в сети посто нного и переменного тока поддерживаетс  одинаковое.The DC and AC network voltage is maintained the same.

В камере, пропаривани  обеспечиваетс  парова  атмосфера с температурой 60°С дл  устранени  возможности высыхани  изделий.In the chamber, the steam is provided with a vapor atmosphere with a temperature of 60 ° C to eliminate the possibility of drying products.

После электропрогрева издели  распалубливают , обрабатывают в автоклаве по режиму 2-1-4+2 час при избыточном давлении 4 кгс/см.After electric heating, the products are spun, treated in an autoclave according to the mode 2-1-4 + 2 hours with an overpressure of 4 kgf / cm.

Получают силикатные издели  с пределом прочности при сжатии 200-225 кг/см. При этом цикл термообработки сокращен на 4 часSilicate products with a compressive strength of 200-225 kg / cm are obtained. The heat treatment cycle is reduced by 4 hours.

при снижении избыточного давлени  пара на 4 кгс/см.with a decrease in steam overpressure by 4 kgf / cm.

Предмет изобретени Subject invention

Claims (2)

1.Способ термообработки силикатных изделий , заключающийс  в электропрогреве свежеотформованного издели  переменным электрическим током с последующей автоклавной обработкой, отличающийс  тем, что, с целью ускорени  процесса и повышени  качества издели , электропрогрев свежеотформованного издели  осуществл ют в паровой среде при атмосферном давлении с одновременной электрообработкой издели  посто нным электрическим током.1. A heat treatment method for silicate products consisting of electrically heating a freshly molded product with an alternating electric current followed by autoclave treatment, characterized in that, in order to accelerate the process and improve the quality of the product, electrically heated the newly formed product is carried out in a vapor medium at atmospheric pressure with simultaneous electroprocessing electric shock. 2.Способ по п. 1, отличающийс  тем, что последующую автоклавную обработку осуществл ют при избыточном давлении 4 кгс/см.2. A method according to claim 1, characterized in that the subsequent autoclave treatment is carried out at an overpressure of 4 kgf / cm.
