Roll Roll
Wiwit tension sing dhuwur dibutuhake ing bagean sing adhem kanthi cepet, kudu nyedhiyakake piranti roller tension ing bagean sing metu lan mlebu ing bagean iki, sing cocog karo ketegangan ing antarane iki lan bagean liyane.
Karakteristik rollara yaiku:

Siji roller ing saben set rollers tension (roller katelu Roller lan roller pisanan Roller Roller) duwe kunci kanggo njaga ketegangan nalika unit mandheg. Kunci nyekeli dilengkapi blok / bantalan rem lan aktuator pneumatik.
Lapisan roller lan cembung
Runtungan tungku dikirim kanthi permukaan sing angel, supaya bisa njaga adhesion sing apik kanggo jalur lan kanggo nyegah skid, sing bisa ngasilake nodul lan goresan. Tujuane lapisan suhu sing dhuwur: a) nambah resistensi nyandhang rolling ing suhu dhuwur, nambah kekerasan, cr28ni48, kanthi nyuda strip, tegalan ora gampang digatekake; b) tujuan kapindho yaiku nolak nodul, nodasi amarga permukaan strip; Utawa amarga udan baja jalur ing suhu sing dhuwur.
Cara nyemprot: A), teknologi nyemprot supersonik, suhu sing digunakake<500℃, using materials: Co base alloy, good low temperature wear resistance, oxidation resistance and good corrosion resistance; working temperature <900℃, using material: NiCr alloy, good thermal corrosion resistance and wear resistance under medium and high temperature conditions, corrosion resistance, corrosion resistance, micro vibration and grinding wear, good corrosion resistance, good wear and oxidation resistance at medium and high temperature.
B), Explosion spraying technology, working temperature>900 Derajat, nggunakake bahan wesi: oksida (keramik logam), resistanance nyandhang suhu sing dhuwur, resistensi oksidasi suhu sing dhuwur, resistensi nodasi).
Gagasan desain materi tahan suhu dhuwur yaiku: Logam (wesi logam) + keramik logam (non-logam). Hardness suhu sing paling apik yaiku keramik non-metalik. Supaya bisa mesthekake yen keramik ora mati, fase logam (ikatan logam) lan keramik logam (non-logam) (barang sing ditundha) kudu ditambahake tes 17, {{7} tes pendinginan banyu.
Prinsip lapisan saka tungku suhu tungku saka supplier tungku disiapake padha, yaiku bagean pemanasan, lan bagean pendinginan sebagean ngetrapake bagean pemanasan lan lapisan resistan panas 050 derajat. Kacang roller kekurangan antara 1 lan 10 μm Ra. Ana sawetara pemasok lapisan lan merek ing saindenging jagad, kaya ing ngisor iki:
