Abstract

The invention discloses a preparation method of a special wear resistant plastic ramming mass for a pure low-temperature cogeneration technology. The method comprises the following steps of: (1) blending raw materials, wherein the raw materials comprise a ramming mass matrix, high-carbon asphalt powder, a surface treating agent and a composite binder, and the ramming mass matrix comprises emery, spheroidal graphite powder, Al2O3 powder, SiO2 micro powder, blue crystal powder and chromium mineral powder; (2) carrying out first-layer mixing on the components in the ramming mass matrix except the Al2O3 powder and the SiO2 micro powder with the high-carbon asphalt powder, then adding the SiO2 micro powder and silicon-aluminum oxide powder which are treated by using the surface treating agent to carry out second-layer mixing, and next, adding the composite binder to carry out a third-layer mixing; and (3) carrying out toughening treatment on the ramming mass by adopting a metal hexsteel, and then carrying out the toughening treatment by blending with steel fibers in the ramming mass. The ramming mass prepared by using the method has wear resistance, long service life and high heat utilization ratio.

Description

technical field [0001] The invention relates to a preparation method of wear-resistant plastic ramming material specially used in pure low-temperature waste heat power generation technology. Background technique [0002] The promotion of pure low-temperature waste heat power generation technology in the cement industry is not only of great significance in terms of energy saving and environmental protection, but also can bring considerable economic benefits. However, due to the erosion and corrosion of waste heat power generation system pipelines by materials and high-density dusty gases for a long time, it is easy to cause defects such as fast wear, short life and low heat utilization rate of the currently used plastic ramming material lining. The downtime caused by wear is quite long every year, which has become a technical problem that plagues pure low-temperature waste heat power generation in China. Therefore, a wear-resistant plastic ramming material dedicated to pure l...
