神户制钢是世界上一流的线材生产厂.现有5套线材轧机,年总生产能力超过200万吨.生产的品种普通钢有软线、硬线、焊条钢和冷镦钢线材;特殊钢有机械结构用碳素钢、易切削钢、低合金钢、琴弦钢、弹簧钢、不锈钢以及高合金钢等.盘条的规格从φ5.5mm一直到φ50mm.对于线材质量从炼钢、开坯到线材成品轧制,以及轧后成品冷却和精整,都有严格的要求.本文只对神户制钢线材轧后成品冷却作一介绍.线材的轧后控制冷却工艺对提高线材质量极为重要.特别是对于高速线材轧机,盘重达2t左右,若在高温状态下卷取,生成二次氧化铁皮厚,晶粒异常粗大,组织和性能
Kobe Steel is the world’s first-class wire rod production plant. The existing five sets of wire rod mill, the total annual production capacity of more than 2 million tons. The production of ordinary varieties of soft wire, hard wire, electrode steel and cold heading steel wire; special steel Mechanical structure with carbon steel, free cutting steel, low alloy steel, string steel, spring steel, stainless steel and high alloy steel, etc. Wire rod specifications from φ5.5mm until φ50mm. For wire quality from steelmaking, open Billet to the wire product rolling, as well as finished product cooling and finishing, have strict requirements.This article only for Kobe steel wire rod product cooling after cooling for an introduction.Wire cooling steel wire rod control and cooling process to improve the quality of wire is extremely important Especially for high-speed wire rod mill, plate weighing about 2t, if the coiling under high temperature conditions, the formation of secondary iron oxide thick, abnormal coarse grain, texture and performance
