产品简介

　　注单历史是现代炼钢和生产中*常用的脱氧剂。在炼钢中注单历史的作用主要有：镇静钢液，防止钢液凝固时产生气泡；形成弥散的AlN粒子，固定钢中的氮，控制钢再加热时的奥氏体晶粒度，提高晶粒粗化温度，降低钢的过热敏感性和淬透性，改善钢的焊接性能；抑制低碳钢的时效特性；降低钢的缺口敏感性和韧脆转变温度等。

　　Product Brief

　　Aluminum wire is the most commonly used deoxidizer in modern steelmaking and production.The role of aluminum in steel are:calm liquid steel,to prevent the occurrence of bubbles of liquid steel during solidification;the formation of AlN particles,fixed nitrogen in steel,the austenite grain size control of steel during reheating,improve the grain coarsening temperature,reduce steel overheating sensitivity and hardenability,improve the steel welding inhibition performance;aging characteristics of low carbon steel;reduce the notch sensitivity of steel and ductile brittle transition temperature.
