Effect of Inner Cooling Apparatus-U Shape Pipe on Flow of Molten Steel in Slab Continuous Casting Mold;

Three flow models of molten steel in mold are introduced,the influence of model on quality of billet discussed,the effect to the model is analyzed from drawing speed,nozzle shape(SEN),nozzle insert depth,argon blow quantity and casting billet width.

Fast refining process of continuous casting liquid steel;

Testingand Application of Liquid Steel Heating up using Silicon Series Alloy Exothermic Agent;

The fluctuation of liquid steel's temperature in tundish of continuous-casting when producing 45# steel is researched,the influence actors analyzed,some improving measures proposed.

Model of prediction for the terminal temperature of molten steel in LF refining;

Model of Predication for Temperature of Molten Steel in a 60 t Tundish;

Model of Prediction for End Temperature of Molten Steel in CAS Refining;

According to the requirements for steel quality of thin slab continuous casting and rolling,comparative analysis on steel qualities in some thin slab manufactories in the world and the existing state in Tangshan Iron & Steel Company is made,based on analysis and calculation of original data of industrial refining.

Characteristics of steel rolling waste water from an iron and steel plant were high water temperature,poor gas dissolving effect,containing oil and suspension,close density of oil and water and serious emulsifying degree.
