Abstract：In order to reduce the environmental pollution and consumption of fossil fuel in the production of ironmaking, subcritical hydrothermal methods were used to treat waste plastics. The obtained solid products (hydrochars) were analyzed,such as ignition temperature,explosiveness,combustion,reactivity,etc.,so as to explore the feasibility of waste plastic hydrochars for blast furnace injection. The results showed that the proximate analysis of the hydrochars HTC-1 produced by plastic pipe (PVC)was similar to bituminous coal,and the characteristics of combustion and reaction of anthracite (YJ) were improved with mixing HTC-1. However,the carbon content of hydrochars HTC-2 produced by beverages bottle (PET) was low (3.33%),the volatiles of it was 96.67%.Therefore,ensuring the security of injection,it was necessary to strictly control the amount of addition.
