山东大鼎钢管厂Seamless steel pipes can be divided into two categories: hot rolling and cold rolling. Hot rolling can be divided into ordinary tubes, medium and low pressure boiler tubes, high pressure boiler tubes, alloy tubes, stainless steel tubes, petroleum cracking tubes, geological tubes, etc. Cold rolling can be divided into ordinary tubes, medium and low pressure boiler tubes, high pressure boiler tubes. Pressure boiler tubes, 山东大鼎金属材料有限公司alloy pipes, stainless steel pipes, etc. In addition to petroleum cracking pipes and other pipelines stainless steel thin-walled pipes and profiled pipes cold-rolled steel plate surface quality, appearance and dimensional accuracy are superior to hot-rolled steel plate, right-rolled product thickness is about 0.18mm, favored by the majority of users.冷轧钢卷作为产品深加工的基板，成为高附加值产品。如镀锌、热浸镀锌、耐指纹镀锌、彩涂钢板卷、吸振复合钢板、PVC层压钢板等，这些产品具有美观、耐腐蚀等优良品质，已得到广泛应用。冷轧卷材退火后必须进行细化，包括切割头、尾部、修边、调平、调平、复卷或纵剪板。冷轧产品广泛应用于汽车制造、家电、仪表开关、建筑、办公家具等行业。每包重量3～5吨。平板轧制的重量一般为3～10吨/体积。线圈内径610mm。
