The heat treatment (carbolite labor

The heat treatment (carbolite laboratory electrical) furnace was pre heated for 1 hour, thereafter; the specimens were heat treated using annealing, normalizing and tempering heat treatment processes.
1
Annealing
The non-inoculated (control) and inoculated (0.2% ferrosilicon) samples were heat treated gradually from ambient temperature( 250C) to 8800C in the carbolite laboratory electrical furnace, and to ensure full austenisation, the samples were soaked for 1hour after which the furnace was turned off , and the samples were then allowed to cool gradually in the furnace.
2
Nomalizing
The non-inoculated (control) and inoculate (0.2% ferrosilicon) samples were heat treated gradually from ambient temperature ( 250C) to 8800C in the carbolite laboratory electrical furnace, and to ensure full austenisation, the samples were soaked for 1hour. The samples were removed from the furnace, and were allowed to cool in air inside the laboratory.
3
Tempering
Four samples comprising two non- inoculated (control) and two inoculated ( 0.2% ferrosilicon) were heat treated gradually from ambient temperature (250C) to a temperature of 6500C that is, below the critical temperature, and held for 1hour and 30 minutes. Thereafter, the furnace was turn off, and the first and second set of samples, one each from un-inoculated and inoculated were taken out and cooled in water and oil respectively.

Perlakuan panas (Carbolite laboratorium listrik) tungku adalah pra dipanaskan selama 1 jam, setelah itu; spesimen dipanaskan menggunakan anil, normalisasi dan tempering proses perlakuan panas.
1
Annealing
The non-diinokulasi (kontrol) dan diinokulasi (0,2% ferrosilicon) sampel dipanaskan secara bertahap dari suhu lingkungan (250C) untuk 8800C dalam tungku listrik laboratorium Carbolite , dan untuk memastikan austenisation penuh, sampel direndam selama 1 jam setelah tungku dimatikan, dan sampel kemudian dibiarkan dingin secara bertahap dalam tungku.
2
Nomalizing
The non-diinokulasi (kontrol) dan menyuntik (ferrosilicon 0,2%) sampel dipanaskan secara bertahap dari suhu lingkungan (250C) untuk 8800C di laboratorium tungku listrik Carbolite, dan untuk memastikan austenisation penuh, sampel direndam selama 1 jam. Sampel dikeluarkan dari tungku, dan dibiarkan dingin di udara di dalam laboratorium.
3
Temper
Empat sampel yang terdiri dari dua non diinokulasi (kontrol) dan dua diinokulasi (0,2% ferrosilicon) yang dipanaskan secara bertahap dari suhu lingkungan (250C) ke suhu 6500C yaitu, di bawah suhu kritis, dan ditahan selama 1 jam dan 30 menit. Setelah itu, tungku itu mematikan, dan yang pertama dan kedua set sampel, masing-masing dari un-diinokulasi dan diinokulasi dibawa keluar dan didinginkan dalam air dan minyak masing-masing.
