To solve the hard problem that the reduction of heat transfer efficiency on the cooling stave of blast furnace due to fouling deposition, solid particles have been added into the cooling water pipes, forming liquid-solid two-phase flow, which can change the heat transfer and anti-fouling capacities of the cooling water pipes. Under the different solid phase volume scores, the heat transfer and anti-fouling capacities of the liquid-solid two-phase flow in the cooling water pipes are studies. The results indicates that because of the perturbation and shearing effect of solid phase particles, not only can the heat transfer coefficient and heat transfer capacity of the cooling water pipes be enhanced, but also the anti-fouling capacity be increased. Thus the highly effective running time of the equipment is greatly extended, realizing the long-term highly effective running of the cooling staves. The blast furnace cooling stave as heat exchange equipment, its heat transfer effects has the very important influence to blast furnace's life. In order to enhance cools wall's cooling capacity, the domestic and foreign scholars around material quality , structure optimization [2-4], dirt cleaning of water pipe , heat-transfer property  of the cooling wall and so on to do the massive fruitful research work. At present, the fouling cleaning of blast furnace stave cooling water pipe wall is still a difficult problem. The high-pressure water washing and sand washing methods are commonly used in industrial practice, these are "doctors after the disease first" and low efficiency methods. The effect removing dirty stuff is not very ideal. The cleaning effect of on-line chemical cleaning is difficult to guarantee. Liquid-solid fluidization cleaning technology can be used in the blast furnace to cool the cooling water pipe wall. It can on-line clean fouling and strengthen heat transfer. Its anti-fouling performance has been studied experimentally.
