连铸钢坯二冷喷嘴热态特性的实验研究
Experimental Study on Hot Characteristics of Nozzle in Slab Continuous Casting
摘要
Abstract
The experimental study is based on unsteady state heat conduction theory. The large steel samples were heated to surface temperature of actual temperature of the slab one side and conducted for water cooling the other side. Experiments were carried out to simulate the influences of nozzles on process of continuous casting billet in secondary cooling zone. The experimental results show that either form of the nozzle, the general trend indicate that heat transfer coefficient increases with pressure increasing. The impact of different kinds of steel was studied, experiments show that the level of carbon content of steel effects on the heat transfer coefficient to a certain extent,heat transfer coefficient is larger with a the higher the carbon content. The experimental results and the actual plant measurements to compare the data calculated, the error is within 5%, which meets the engineering needs.关键词
