1. A method of forming one or more lining layers in a cathode shell of an Aluminium electrolysis cell, the method comprising:
pouring one or more layers of at least one lining material onto a bottom of the cathode shell, each layer of the one or more layers being spread and leveled over a surface of the cathode shell,
simultaneously spreading and leveling a layer comprised in the one or more layers of the at least one lining material over the surface of the cathode shell by means of a belt-roller sector gate, wherein:
the leveling is executed at a preset level measured from a plane of an upper edge of the cathode shell of the Aluminium electrolysis cell, and
one or more lining layers are formed in succession with similar or different physical and performance properties specified according to design features of the Aluminium electrolysis cell.
