Description
Износостойкий чугун дл деталей машин, работающих в услови х гидроабразивного износа по авт. св. № 151366 имеет следующий состав, о/о: углерод 2,4-2,8; кремний 0,5- 0,7; марганец 1,8-3,5; хром 14-22; никель 1,8-3,5; сера не более 0,1 и фосфор не более 0,1. Использование такого чугуна ограничено ввиду трудности его обработки.Wear-resistant cast iron for machine parts operating under conditions of hydroabrasive wear auth. St. № 151366 has the following composition, o / o: carbon 2.4-2.8; silicon 0.5-0.7; manganese 1.8-3.5; chrome 14-22; nickel 1.8-3.5; sulfur is not more than 0.1 and phosphorus is not more than 0.1. The use of such cast iron is limited due to the difficulty of its processing.
Цель изобретени - улучшить обрабатываемость чугуна. Дл этого предложено снизить нижний предел по содерлсанию углерода до 1,6о/о, а по содержанию никел до 0,8о/о и подвергать чугун термообработке по режиму; нагрев до 850-870°С со скоростью 80- OQ°C/4ac, выдержка 1 час на 25 мм толщины издели , охлаждение с печью.The purpose of the invention is to improve the workability of cast iron. To this end, it has been proposed to lower the lower limit on carbon content to 1.6 o / o, and on nickel content to 0.8 o / o and to heat the iron according to the mode; heating to 850-870 ° С at a rate of 80- OQ ° C / 4ac, holding for 1 hour per 25 mm of the thickness of the product, cooling with an oven.
После того как издели обработаны до необходимой формы и размеров дл повышени износостойкости их подвергают термообработке . При закалке издели нагревают до 910 - 930°С со скоростью 80-100°С час, выдерживают 1 час на 25 мм толщины издели и охлаждают на воздухе. При отпуске нагрев ведетс до 230-250°С, затем выдерживают в течение одного часа и охлаждают на воздухе.After the products have been processed to the required shape and size, they are subjected to heat treatment to increase wear resistance. During quenching, the product is heated to 910 - 930 ° C at a speed of 80-100 ° C hour, kept for 1 hour per 25 mm of the product thickness and cooled in air. During tempering, the heating is conducted to 230-250 ° C, then held for one hour and cooled in air.
Твердость чугуна после термообработки составл ет 600-650 Нв.The hardness of the cast iron after heat treatment is 600-650 Hv.
