Kāohi ʻana a me nā ana hoʻomalu no ka Tandem Cold Rolling Mill

Hiki ke ʻano paheʻe i ka wā o ka ʻōwili ʻana, ʻo ia hoʻi, ka paheʻe pili ma waena o ke kaula a me kawili wili, ma ke ano nui, ua hoololi loa ia ka wahi deformation o ke kaula e ka mua a i ole ke kua.Hiki ke hoʻololi iki i ka maikaʻi o ka ʻili a me ka hua o ka ʻōpala, a i ʻole ke kumu i haki ʻia ai ka puʻu kila, i ka noiʻi i hala, ua maʻa ka poʻe ma mua o ke kumukūʻai paheʻe a i ʻole ka nui o ka waiwai piha o ke kihi kū ʻole. kumu no ka hoʻoholo ʻana i ka paheʻe, ʻoi aku ka liʻiliʻi o ka waiwai paheʻe mua a i ʻole ka huina kū ʻole, ʻoi aku ka nui o ka paheʻe.ʻO kaʻoiaʻiʻo, he mea ʻepekema loa kēia.No ka laʻana, no kawili anu tandem, ʻo ka huina kū ʻole o ke kū hope, ʻoi aku ka liʻiliʻi o ka waiwai paʻa o ka paheʻe mua ma mua o nā kū mua, akā ʻaʻole kēia manaʻo e paheʻe ke kū.

1. Holo ka mama

Me ka piʻi ʻana o ka wikiwiki o ka ʻōwili ʻana, piʻi ka mānoanoa o ke kiʻi lubricant, emi ka coefficient o ka friction, piʻi ka nui o ka paheʻe ʻana, a lilo ke kaʻina ʻōwili i paʻa.Akā, ma muli o ka hana 'ōwili hou, pehea e hoʻomaikaʻi ai i ka hana pono, ua lilo ka holo wikiwiki i ka pahuhopu o ka laina hana, no laila i ka pale ʻana a me ka mālama ʻana i ka slippage ʻaʻole pono e lilo i ka wikiwiki e like me ke kumukūʻai.

2. Pūnaehana lubrication

Me nā ʻano like ʻole o ka wai lubricating, ka ʻike, ka mahana, a me nā mea ʻē aʻe, pili lākou i ka mānoanoa o ka kiʻi lubricant ma o nā loli i ka viscosity.No kaTandem Cold Mill, ʻO ke koho o ka ʻōnaehana lubrication ke kuleana nui i ka pale ʻana a me ka mālama ʻana i ka paheʻe kekahi o nā kuhikuhi nui.Ma o ka nānā ʻana, hiki iā mākou ke ʻike me ka piʻi ʻana o ka viscosity wai lubricating, piʻi ka mānoanoa o ke kiʻi ʻaila lubricating, emi ka friction coefficient, a, i ka piʻi ʻana o ka hoʻonui ʻana a me ka emi ʻana o ka mahana, piʻi ka viscosity fluid lubricating.Ma keia ano, no kahale wili anuhiki iā ʻoe ke pale i ka paheʻe ʻana ma o ka hoʻohaʻahaʻa pono ʻana i ka wai lubricating a me ka hoʻomaikaʻi ʻana i ka mahana o ka wai lubricating.

3. Pūnaehana hoʻopaʻapaʻa

Me ka hoʻonui i ka post-tension, deformation zone lubrication layer mānoanoa, no laila no ka maʻalahi o ka paheʻe ʻana o ka pahu, hiki ke hoʻemi pono ʻia e ka post-tension e pale i ka paheʻe.

4. Mill Rollʻoʻoleʻa

Hoʻopili nui ka ʻōleʻa ʻōwili i ka coefficient friction, e like me ka emi ʻana o ka roughness ʻōwili, emi pū ka friction coefficient, maʻalahi ka paheʻe.ʻO ka ʻōlelo maʻamau, pili loa ka ʻōwili a me nā tonage ʻōwili i ka hoʻololi ʻana o nā ʻōwili i ka manawa e kōkua i ka pale ʻana i ka paheʻe.
