Description
Преимуществом предлагаемой печи с электрическим обогревом по сравнению с существующими вл етс то, что в ней применены вмеаго т желых чугунных горщков весом 540 кг щики из тонкой листовой л ароупорной стали весом 25 кг, в которые вместо балластного песка засыпают коксовый щтыб, предохран ющий издели от окислени .The advantage of the proposed electric heating furnace as compared to the existing ones is that it employs heavy heavy cast-iron potals weighing 540 kg and drawers made of 25 kg thick sheet steel resistant steel, into which, instead of ballast sand, they pour coke bake that protects the product from oxidation.
Печь имеет четыре температурных зоны: предварительного подогрева деталей при низкотемпературной выдержке; окончательного нагрева изделий и первой стадии графитизации; охлаждени ; второй стадии графитизации . Максимальна температура в печи составл ет 970°. Электронагреватели размещены в первой, второй и четвертой зонах на поду и своде печи и состо т из самосто тельно регулируемых секций. При выходе из стро отдельные электронагреватели могут быть заменены новыми без прекращени работы печи.The furnace has four temperature zones: preheating parts at low temperature exposure; final heating of the products and the first stage of graphitization; cooling; second stage of graphitization. The maximum temperature in the furnace is 970 °. Electric heaters are located in the first, second, and fourth zones on the hearth and roof of the furnace and consist of independently adjustable sections. Upon breakdown, individual electric heaters can be replaced with new ones without stopping the operation of the furnace.
Применение легковесных томильных щиков обеспечивает максимально выгодное размещение изделий в печи при термообработке.The use of lightweight tomilnychikov provides the most favorable placement of products in the furnace during heat treatment.
Предлагаема печь позвол ет сократить общую длительность времени томлени до 36 час. при производительности ее 5 г ковкого чугуна Г: сутки.The proposed furnace reduces the total duration of the languor to 36 hours. with a productivity of 5 g of ductile iron G: day.
Предмет изобретени Subject invention
Электропечь дл томлени изделий из ковкого чугуна, снабженна механизмом дл передвижени щиков с издели ми вдоль печи, отличающа с тем, ЧТО, с целью сокращени продолжительности цикла томлени , применены щики, выполненные из листовой жароупорной стали и заполн емые коксовым щтыбом дл защиты изделий от окислени .An electric furnace for languishing products of ductile iron, equipped with a mechanism for moving boxes of products along the furnace, characterized in that THAT, in order to reduce the duration of the cycle of languor, applied boxes made of heat-resistant steel sheets and filled with coke bristles to protect products from oxidation .
