The utility model content
Technical problem to be solved in the utility model is that the band coil of strip is through after rolling, band coil of strip outer ring, inner ring and middle portion are uneven, thereby when causing subsequent anneal, the problem that weighs wounded or bond with inner ring of steel coil and outer ring, and provide a kind of annealing furnace cellular convection plate for this problem.
The band coil of strip need be placed on before sending into annealing furnace on the annealing furnace cellular convection plate, and the utility model discovery improves annealing furnace cellular convection plate and helps to solve the problems of the technologies described above, and concrete scheme is:
A kind of annealing furnace cellular convection plate, comprise panel, base plate and the intermediate plate between panel and base plate, it is characterized in that the outer chamfered end of panel that described annular panel comprises the panel body, is positioned at the panel chamfered end of panel body ring one side and is positioned at panel body outer shroud one side;
And/or
The outer chamfered end of base plate that described base plate comprises the base plate body, is positioned at the base plate chamfered end of base plate body ring one side and is positioned at base plate body outer shroud one side.
Annealing furnace cellular convection plate with carry out chamfered with the corresponding part in inner ring of steel coil and outer ring, can greatly alleviate like this annealing furnace cellular convection plate to the pressure with inner ring of steel coil and outer ring, thereby greatly reduce the probability of occurrence that weighs phenomenon and bonding phenomenon wounded with coil of strip.
The utility model has also adopted following technical scheme:
The chamfer angle number average of the interior chamfered end of chamfered end and base plate is 0-6 ° in the described panel, and the internal diameter of the interior chamfered end of chamfered end and base plate and the difference of external diameter all are controlled within the 518mm in the described panel;
The chamfer angle number average of the outer chamfered end of described panel and the outer chamfered end of base plate is 0-6 °, and the outer chamfered end of described panel and the internal diameter of the outer chamfered end of base plate and the difference of external diameter all are controlled within the 570mm.
Description of drawings
Fig. 1 is the sectional view of embodiment 1 described a kind of annealing furnace cellular convection plate;
Fig. 2 is the sectional view of embodiment 2 described a kind of annealing furnace cellular convection plates.
Embodiment
The utility model is on the basis of existing annealing furnace cellular convection plate, convection-plate and band inner ring of steel coil and the contacted part in outer ring are carried out chamfered (being respectively chamfered end and the outer chamfered end of base plate in chamfered end in the panel, the outer chamfered end of panel, the base plate), thereby after will being with coil of strip to be placed on the convection-plate, convection-plate can be dispersed in each position with coil of strip more uniformly to the pressure with coil of strip.
In order further to improve the described technique effect of epimere, the utility model also in the counter plate in chamfered end and the base plate chamfered end limit, making the chamfering number of degrees of chamfered end in the interior chamfered end of panel and the base plate is 0-6 °, the internal diameter of the interior chamfered end of chamfered end and base plate and the difference of external diameter all are controlled within the 518mm in the panel, can make so the interior chamfered end of panel and the interior chamfered end of base plate cover the band inner ring of steel coil that elongates with respect to the coil of strip middle portion fully, and can offset fully by cold-rolling process cause with the coil of strip middle portion and with the difference between the inner ring of steel coil, thereby can not cause the adverse consequences that weighs wounded even bond with inner ring of steel coil.
In like manner, the utility model also outer chamfered end of counter plate and the outer chamfered end of base plate limits, making the chamfering number of degrees of the outer chamfered end of panel and the outer chamfered end of base plate is 0-6 °, the outer chamfered end of panel and the internal diameter of the outer chamfered end of base plate and the difference of external diameter all are controlled within the 570mm, can make so the outer chamfered end of panel and the outer chamfered end of base plate cover the band coil of strip outer ring of elongating with respect to the coil of strip middle portion fully, and can offset fully by cold-rolling process cause with the coil of strip middle portion and with the difference between the coil of strip outer ring, thereby can not cause the adverse consequences that weighs wounded even bond with the coil of strip outer ring.
