The utility model relates to a refractory brick cutting appliance, in particular to a refractory brick cutting machine for blast furnace masonry construction. Including a lower bracket, an upper bracket fixed on the lower bracket, a motor, a saw blade and a protective cover installed on the upper bracket, the lower bracket is provided with a water tank, a rail is arranged in the water tank, and a rail is placed on the rail. The trolley is equipped with a base plate with an adjustable inclination angle and an angle fixing plate for positioning the inclination angle of the base plate through folding pages. Two sliding grooves are fixed on the upper part of the base plate. Angle steel.

The utility model can not only ensure the dimensional accuracy of the processed bricks, but also ensure the randomness of the processing angles, thereby avoiding the negative factors brought by the inaccurate processing size of ordinary brick cutting machines to the service life of the blast furnace, and greatly increasing the service life of the blast furnace. The service life of the furnace body; its dust removal and cooling device avoids the problem of environmental pollution. In addition to ucar brick processing, this machine can also be used for similar brick processing.
