Nimbulaké lan solusi kanggo pori ing casting tliti sol silika

Porositas iku umumcasting tliticacat. Porositas nuduhake cacat bolongan Gamelan ing posisi individu casting tliti sol silika. Porositas biasane ditemokake sawise diproses. Digabungake karo pengalaman produksi bengkel pirang-pirang taun, panyebab lan cara pencegahan pori-pori ing casting presisi diringkes:

I. Penyebab pembentukan:

1. Ing kasus paling, generasi pori utamané amarga ora nyukupi roasting saka Nihan saka silika sol tliti casting crystallizer. Nalika pouring baja molten, cangkang saka crystallizer ora bisa dibuwang lancar, lan banjur invades logam Cairan kanggo mbentuk pori.

II. Amarga proses nggawe cangkang utawa materi cangkang, permeabilitas cangkang banget miskin, lan angel ngeculake gas saka rongga. Pori-pori dibentuk kanthi mlebu ing logam cair.

3. Casting pori disebabake Gagal saka online ing baja molten sak proses pouring.

II. Cara Nyegah

1. Nalika kahanan casting tliti ngidini, bolongan exhaust disetel ing titik paling dhuwur saka struktur Komplek saka casting.

2. Nalika ngrancang sistem pouring, syarat exhaust saka cangkang kudu dianggep kanthi lengkap.

3. Suhu baking lan wektu cangkang kudu cukup, lan wektu jampel kudu cukup.

4. Lilin kudu rampung dibusak sak dewaxing.

5. Appropriately shorten the distance from the pouring gate to the pouring cup to make the pouring speed uniform to ensure that the cavity in the molten steel is filled and stable, and as little air as possible is involved in the molten steel, so that the gas in the cavity and the molten steel can be discharged smoothly.
