Ceramic Welding for “J” type hanging wall

The third row of hanging bricks on the nasal part of double “J” type hanging wall at the refining section of the inlet neck of the 500 T float glass furnace fell off, forming a trapezoidal gap which was approximately 4,500 ㎜long, approximately 450 ㎜wide at the lower-mouth, about 250 ㎜ wide at the upper-mouth and about 200 ㎜ thick; the hanging wall was displaced downward seriously and endangered the furnace structure. With the high temperature periscope, the company spent only 4 days in dealing with such a complex case by using the ceramic Welding without affecting the production. Positions soldered were in good operation condition for 25 months in a row.
