3.MATHEMATICAL MODEL OF BURDEN DISTRIBUTION FOR BELL-LESS TOP OF BLAST FURNACE
4.APPLICATION OF COKE COLLAPSE THEORY IN MATHEMATIC MODEL FOR BURDEN DISTRIBUTION IN BELL TOP BLAST FURNACE
5.Through the analysis and consideration of effect factors and characters in burden distribution of bell less BF,mathematical model for burden distribution of bell less BF is established based on predecessors? achievements and computer technology.
6.al. This paper put forward the reasonable mathematical formula which simulate refered physics phenoma, develop mathematical model and develop computer program, show the burden flow trajectory, the formation process of burden layer, the ratio of ore to coke, radial distribution of size, radial distribution of gas flow velocity and establish the burden distribution mathematical model of bell top blast furnace on the basis of analyzing the basic factors and combine the real condition of bell-movable armor blast furnace.
7.The 2500 m 3 blast furnace at Maanshan Iron and Steel Co , Ltd was put into operation on April,1994 Based on the practice of simultaneous conditioning of upper and lower parts, the rule of burden distribution in bell less top, the reasonable area parameters of tuyere and distribution of gas flow were found The coke quality has great influence on the hearth condition, distribution and utilization of gas
8.The construction of reversion form of burden proof in civil procedure deepens the theoretical research and instructs the distribution and application of burden proof in lawsuit practice from theoretical height.
9.Within the revenue system of the government, the level of tax burden and the size of various fees, as well as the distribution pattern and management is important issues, involving concerns from enterprises, individuals, central government and local authorities.
10.Government finance should be based on the principle of equitable distribution of the economic burden, which means that those who have money should contribute money.
