Abstract
Wearing ring merupakan komponen yang memiliki
kontak langsung dengan shell kiln dan berfungsi untuk
melindungi tyre ring dari kerusakan yang terjadi sehingga
mengganggu aktivitas produksi. Kerusakan berupa fatigue
dikarenakan terkena beban cyclic, tegangan axial dan shear
stress yang terus menerus menyebabkan wearing ring
mengalami kegagalan. Wearing ring menggunakan material
ASTM A36. Pada pengujian OES didapatkan hasil komposisi
kimia yang sesuai dengan standar yaitu kadar karbon sebesar
0,21% dan unsur Fe sebesar 97,7%. Pada pengujian kekerasan
dilakukan pada 2 daerah menggunakan metode brinell
didapatkan hasil rata-rata yaitu jauh patahan sebesar 133 BHN
dan dekat patahan 139,8 BHN dan sesuai standar yaitu 110-149
BHN. Pada pengujian metallografi didapatkan hasil berupa fasa
yang terbentuk adalah ferit-perlit. Hasil perhitungan pada
penelitian wearing ring tyre ini didapatkan tegangan geser yang
bekerja sebesar 191,46 MPa dari yang diizikan yaitu sebesar 400
MPa dengan torsi sebesar 47,4 Nm. Dan ini disebabkan oleh
kesalahan pemasangan stopper yang berlebih sehingga wearing
ring putus yang dibuktikan juga pada simulasi menggunakan
solidwork.
============================================================
Wearing Ring is a component that has direct contact with
the kiln shell and serves to protect Tyre Ring of the damage that
occurred, disrupting production. Damage in the form of
fatigue due struck a cyclic load, axial tension and shear stress
continue to cause wear ring failure. Wearing the ring using
the material ASTM A36. On the OES testing showed that the
chemical composition according to the standards that the carbon
content of 0.21% .and at 97.7% Fe element. In hardness testing
performed on 2 areas that is far from the fracture and fracture the
close of each 6 points Brinell indentation method showed an
average that is far fracture by 133 BHN and near fault 139.8
BHN and standards compliant is 110-149 BHN. In metallografi
test results obtained in the form of a phase that is formed is a
ferrite-pearlite. The calculation in the study was obtained tire
wear ring shear working of 191.46 MPa from which denied entry
amounting to 400 MPa with a torque of 47.4 Nm. And this is
caused by faulty installation of excess stopper so that the wear
ring broke evidenced also in the simulation using solidwork..
