MS Flat Bar/Carbon Steel Flat Bar/Chitsulo Choyaka chozinga cha Flat Bar
1. Zolemba zapadera za mankhwala.Makulidwe ake ndi 8 ~ 50mm, m'lifupi ndi 150-625mm, kutalika ndi 5-15m, ndipo mawonekedwe ake ndi ochulukirapo, omwe amatha kukwaniritsa zosowa za ogwiritsa ntchito.Itha kugwiritsidwa ntchito mwachindunji m'malo mwa mbale yapakati popanda kudula ndipo imatha kuwotcherera mwachindunji.
2. Pamwamba pa mankhwala ndi osalala.Njira yochepetsera madzi yothamanga kwambiri imagwiritsidwa ntchito kawiri poonetsetsa kuti pamwamba pazitsulo ndi zosalala komanso zoyera.
3. M'mbali mwake ndi ofukula, ndipo ma rhomboid ndi omveka.Mipiringidzo iwiri yoyimirira pomaliza kugubuduza imatsimikizira kuyimirira bwino mbali zonse, ngodya zowoneka bwino, komanso mawonekedwe abwino ambali kumbali.
4. Kukula kwa mankhwalawa ndi kolondola, kusiyana kwa mfundo zitatu, kusiyana kwa msinkhu komweko kuli bwino kuposa muyezo wachitsulo;mankhwalawo ndi owongoka ndipo mawonekedwe ake ndi abwino.Kumaliza kugubuduza kumagwiritsa ntchito kugudubuza kosalekeza komanso kuwongolera kodziwikiratu kuonetsetsa kuti palibe chitsulo chomwe chimawunjikidwa komanso palibe chitsulo chomwe chimakoka.Chogulitsacho chimakhala cholondola kwambiri.Kulekerera, kusiyana kwa mfundo zitatu, kusiyana kwa mizere komweko, kupindika kwa chikwakwa, ndi magawo ena ndizabwino kuposa mbale yapakatikati.Digiri yabwino.Kudula-kumeta ubweya wozizira, kulondola kwambiri kutalika kwake.
5. Zomwe zimapangidwira zimatengera chikhalidwe cha dziko, chomwe chili chofanana ndi mbale yachitsulo.Miyezo yaukadaulo ndiukadaulo idapangidwa molingana ndi miyezo ya YB / T4212-2010 (Q345B / Q235B imanena za GB / T1591-94 ndi GB / T700-06, motsatana)
