FOREHEARTHS AND W-E SUPERSTRUCTURE

Dear Customer

FOREHEARTHS AND W-E SUPERSTRUCTURE IS ONE OF IMPORTANT ISSUE TO GET A GOOD GLASS CONDITIONING.

ACCORDING TO DESIGN, SUPERSTRUCTURE CAN BE MONOLITHIC, MADE IN A FEW PCS, EVEN PLATE, OR COMPLICATE SHAPE.

OUR PRODUCTION COVERS ALL TYPE OF IT AND, IN LAST 13 YEARS, WE HAVE PRODUCED MORE THAN 40 DIFFERENT DESIGNS FOR ALL OUR CUSTOMERS AROUND THE WORD.

DIMENSION OF COVER COULD ARRIVE AT 3500 mm UP TO 2500 KG

MANLY PROBLEM OF PRODUCTION IS TO MAINTAIN A CHARACTERISTIC OF PRODUCT AS GOOD DISTRIBUTION OF MATERIALS INSIDE, HANDLING AND AS WELL GOOD FIRING.

WE ARE NOT JUDGE TO DECIDE IF ONE COVER IS BETTER THAN OTHER BUT, WE CAN SUPPORT OUR CUSTOMER TO DETERMINATE IF A DESIGN COULD BE FIT WITH REFRACTORY PRODUCTION AS WELL QUALITY OF REFRACTORY CAN BE FIT WITH GLASS QUALITY.

ACCORDING TO THE PICTURE 1 & 2 YOU CAN SEE A MONOLITHIC SUPERSTRUCTURE USED IN K48’’ W-E AFTER 12 YEARS OPERATION IN HIGH ALKALI GLASS.

WHERE IT WAS INSTALLED, PAST APPROX. 810.000 TONS OF GLASS AT ABOUT 1300-1340°C

ACCORDING TO GENERAL VIEW, WE CONSIDER A GOOD RESULT OF MATERIALS.

EACH SINGLE BLOCK OF SUPERSTRUCTURE WAS GRINDED AND, AS YOU CAN SEE IN THE PICTURE, RESULT WAS GOOD. NO PENETRATION IN THE STONE AND BETWEEN JOINT

OTHER CONSIDERATION IS ABOUT COLOR, FURNACE ON HIS LIFE PRODUCED TWO DIFFERENT COLOR AMBER AND DARK GREEN.

Many thanks for your attention.

Yours Sincerely
