1.After positioning the crucible mold , with pestle built fork the peripheral mould and wall lining 's junction of the exposed part of the lining material to build four times, add the wall lining material began to pestle sidewall . Note donnt damage the lining material or contamination of lining.
2. Feed materials to the sidewall with appropriate thickness , find level of the lining material and fork four times to remove air with fork and shovel.
when the material depth is greater than 0.8 m or furnace capacity is greater than 3 t , it should be adopted under the hopper feeding, so as to avoid material segregation wirh dust float in the sky.
3. Each layer after feeding, use light check carefully any entrained debris in the lining material, metal, plastic or cloth pieces, and once found, should be immediately removed.
4. According to the operating procedure charging and fork up, until the wall lining material added to the stove top.
5. After pestling and building at the top of the Electric furnace is completed, cut off the top the sidewalls of the excess length (100 mm) back.
