The invention relates to a movable carborundum 
smelting furnace. The movable carborundum 
smelting furnace comprises a furnace vehicle, a gas collecting tank and a track, wherein longitudinal bearing beams are arranged in a furnace vehicle 
chassis; bearing seats on the two sides of vehicle wheels are fixed to the bearing beams through bolts; insulation sleeves are arranged outside studs in a sleeving mode; insulation mats are arranged between the bearing seats and the bearing beams; and insulation mats are also arranged between gaskets and the bearing beam as well as between the gaskets and the bearing seats; each side seam is divided into a left part and a right part, wherein a side seam insulation mat is arranged between each 
left half part and each right half part, the shape of each side seam insulation mat is the same as the cross-sectional shape of each side seam; the 
left half parts and the right half parts are connected through bolts;, insulation sleeves are arranged outside studs in the sleeving mode; the insulation mats are also arranged between the spacers and the 
left half parts as well as between the spacers and the right half parts; and plugging board 
doors are arranged at the lower parts of the side seams. According to the movable carborundum 
smelting furnace disclosed by the invention, an insulation structure is designed, so that the problem of large electric loss of the movable carborundum smelting furnace is solved; the plugging board 
doors are designed on the lower parts of the side seams, so that the problems that the opening degree of a conventional lower 
discharge door is difficult to control, materials are liable to leak, and the smelting furnace is greatly affected due to heating deformation are solved.
