Abstract

The invention discloses a viewing port assembly structure of an anode roasting furnace, comprising a cover and a stand (4), wherein an upper cover (3) is connected with a lower cover (2) trough a bolt(3) so as to form the cover; the stand (4) is connected with a furnace chamber framework (6) through a connection plate (5), and the stand (4), the connection plate (5) and the furnace chamber framework (6) are poured into an integer through castables (7); and the cover and the stand (4) are sealed by a refractory fiber rope (8). The invention has the advantages of simple structure formation, convenient construction, low implement cost, stable using property, long service life, ensured product quality and capacity, high heat energy utility ratio and low operation and maintenance cost.

Description

technical field [0001] The invention relates to a carbon anode roasting furnace production device, in particular to an anode roasting furnace observation hole structure. Background technique [0002] At present, the production of open-type carbon anode roasting furnace requires the temperature in the fire channel to reach 1100-1300 ℃, and there are 4 observation holes on the top of each fire channel in each furnace chamber. In the prior art, the structure of the observation hole assembly generally adopts the combination of low carbon steel and refractory fiber as the cover, and the heat-resistant cast iron as the seat. The problems of this structure are: 1) Due to the manufacturing error of the cover and the expansion at high temperature, And the bonding phenomenon between the refractory fiber and the heat-resistant cast iron seat at high temperature causes the cover and the seat to be stuck and cannot be opened, which affects the normal operation of the furnace; If it is n...
