description	The utility model provides a draught fan at the bottom of a furnace for a vertical type cracking furnace, comprising a slag-baffling draught plate and a high temperature-resistant fragment layer, wherein the high temperature-resistant fragment layer is paved above the slag-baffling draught plate. After the technology is adopted, the contact opportunity between slag in the furnace and a draught system can be reduced, the compensation speed of combustion-supporting oxygen in the blast furnace can be accelerated, the cracking and burning efficiency can be guaranteed, the temperature in the furnace can be raised, the cracking degree and the oxidizing efficiency of a material in the furnace can be increased, the energy consumption can be reduced, the service life of the cracking furnace can be prolonged, and the maintenance period can be shortened.
