He ʻoʻoleʻa maikaʻi kona. Ma ka hoʻomalu pono ʻana i ka haku mele, e hoʻemi ana i ka ʻike o nā mea ʻino i loko o ka pā kila kalapona Q235D, a me ke koho ʻana i nā kūlana mālama wela kūpono, ʻo ka pā kila NM360 ka paʻakikī maikaʻi. No laila, hiki ke kūkulu ʻia nā ʻāpana kūkulu hilinaʻi kiʻekiʻe e like me ka hiki ʻole o nā ʻāpana ʻaʻahu. Hoʻohana ʻo Q235D carbon steel plate i ka ʻenehana kiʻekiʻe a me nā mea hana, i hui pū ʻia me ka hoʻokele ʻenehana kiʻekiʻe a me ka ʻepekema, i ʻano like a nani nā mea a me ke ʻano o ka huahana.
S355J2 pā kila Q235D carbon steel plate rolling process is a controlled rolling process. I ke kaʻina hana ʻōwili, ʻo 1000-1050 ° C ka mahana o ka ingot; Hoʻohana ka pae mua i kahi kaʻina hana hoʻohaʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ʻo ka pae wela kiʻekiʻe ʻo 950-1000 °C, ʻo ka wikiwiki o ka holo ʻana he 1.6-2.0m /s, ʻo ka helu hoʻemi hoʻokahi o ka pā kila kalapona Q235D. ʻO 15-20%, a ʻo ka huina hoʻemi kumulative he 40-45% e hōʻoia i ka deformation piha o ka ingot. I ka pae mua, ʻo 910-930 °C ka wela hoʻomaka ʻana, a ʻo ka wela hoʻopau ʻana ʻo ≤ 870 °C.
