This disquisition is about the general situation of the stuff load and distribution equipment on the blast furnace bell-less top, and expatiate on the design characteristics and the problems of the vital equipment such as sealed valve, flow control valve and stuff distribution facility in the two advanced type bell-less top equipment (parallel hopper type and series hopper type) in the world.

Adopting the comprehensive burden distribution technique in No2 BF at Zhangdian Iron & Steel Works;

A key link of burden distribution in the bell-less BF top----the formation of terrace;

Study of mathematical model for burden distribution of bell less BF;

The optimization of top distribution model for No 5 BF of Ironmaking Plant inWuhan Iron and Steel Group Co;

In the suitable distribution condition of sinter mixture , the utilization coefficient.

Study on coke size distribution in bell-type charging in CDQ shaft;

Some ideas and measures have been carried out for a year on 2000m~3 BF of New Iron -making Plant based on the variation of charging and coke rate.

Although many works have been done on fluid simulation, little attention has been paid to the staining effect on cloth.

This article has discussed how to simulate cloth with the help of computer graphics, intro- duced some fundamental theories of computer graphics.

The present paper uses the particle-based model proposed by the authors to study cloth deformations when it contacts with other articles.
