Elevator furnace for testing spreadability of hot state repair material and testing method

The invention relates to an elevator furnace for testing spreadability of a hot state repair material and a testing method and relates to the field of testing devices. The elevator furnace for testing spreadability of the hot state repair material comprises a heating furnace with an opening the bottom, a furnace bottom plate capable of lifting to open and close the opening, a lifting device for driving the furnace bottom plate to lift, a spreading liner plate arranged on the top surface of the furnace bottom plate, a blowing device communicated with the heating surface via a blowing pipe and a tail gas treatment device communicated with the heating furnace via a smoke pipe. The elevator furnace for testing spreadability of the hot state repair material and the testing method can be used for simulating and measuring the spreadability of the hot state repair material at a high temperature accurately and reducing pollution of black smoke generated by organic matters in a test material to a test room. 一种测试热态修补料铺展
