Background technology
High-temperature ring annealing furnace is master operation and the equipment that silicon steel is produced, and this lehre is made up of preheating section, heating zone, soaking zone, cooling section, and the highest furnace temperature can reach 1300 ℃.Heated material is realized the thermal treatment of coil of strip through the rotation of furnace bottom chassis.The ring annealing furnace furnace bottom is made up of 50 chassis; During lehre capital construction; The masonry way that structure of refractory all adopts refractory brick to combine with mould material in each chassis, promptly chassis is provided with the cup dolly of certain altitude, and refractory brick is built by laying bricks or stones and on cup dolly, is formed circular configuration; The refractory brick outer ring adopts refractory castable to pour into ring texture; Hot loose down to prevent refractory brick, the while is provided with the straight-through dilatation joint of certain width between ring-type mould material and refractory brick, be convenient to the expansion of internal refractory brick.
Ring annealing furnace is after operation after a while, because the difference that the difference of refractory brick and mould material performance, especially heater wire change; Cause between refractory brick and the ring-type mould material slit to increase, make the sealing silica sand that seals get in the crackle, the temperature variation when silica sand moves along with chassis and produce volume change; Cause the chassis structure of refractory unstable, in addition, the ring-type mould material is shunk big; Cause the cup dolly levelness to present low inside and high outside phenomenon; The bracing or strutting arrangement that causes being provided with its upper support coil of strip its surface finish under hot and load situation occurs making the coil of strip defective obviously increase than large deviation with levelness, can produce in a large number " impression " or " elephant pin " defective etc. as being with steel; The side cut amount of silicon steel significantly increases, rejection number increases, lumber recovery reduces, and ton steel cost significantly increases.
Summary of the invention
The utility model technical problem to be solved provides a kind of anti-equipment structure of silicon steel ring annealing furnace chassis; This anti-equipment structure has overcome the defective that traditional refractory brick combines and builds by laying bricks or stones with mould material; Guarantee the consistence of chassis refractory materials heater wire velocity of variation and the stability of structure of refractory, effectively improved silicon steel lumber recovery and chassis work-ing life.
For solving the problems of the technologies described above; The anti-equipment structure of the utility model silicon steel ring annealing furnace chassis comprises the chassis cup dolly and builds the refractory brick on said cup dolly by laying bricks or stones; Also comprise some flat wedge refractory brick, plurality of side wedge refractory brick and annular refractory fiber blanket; Said plurality of side wedge refractory brick is built by laying bricks or stones on the said cup dolly and around the refractory brick on the said cup dolly; Between the refractory brick on said plurality of side wedge refractory brick and the said cup dolly first dilatation joint is set; Said some flat wedge refractory brick is built by laying bricks or stones on said plurality of side wedge refractory brick and around the refractory brick on the said cup dolly; Between the refractory brick on said some flat wedge refractory brick and the said cup dolly second dilatation joint is set, the position of said first dilatation joint and second dilatation joint is crisscross arranged, and said refractory fiber blanket is layed in said some flat wedge refractory brick and is adjacent on the refractory brick of cup dolly and covers said second dilatation joint.
Further, above-mentioned refractory fiber blanket is to contain the chromium refractory fiber blanket, and its thickness is 25mm.
Because the anti-equipment structure of the utility model silicon steel ring annealing furnace chassis has adopted technique scheme; Be that this anti-equipment structure comprises the chassis cup dolly and builds the refractory brick on cup dolly by laying bricks or stones; Also comprise some flat wedge refractory brick, plurality of side wedge refractory brick and annular refractory fiber blanket; Plurality of side wedge refractory brick is built by laying bricks or stones on the cup dolly and around the refractory brick on the cup dolly; First dilatation joint is set between the refractory brick on plurality of side wedge refractory brick and the cup dolly; Some flat wedge refractory brick are built by laying bricks or stones on plurality of side wedge refractory brick and around the refractory brick on the cup dolly; Between the refractory brick on some flat wedge refractory brick and the cup dolly second dilatation joint is set, the position of first dilatation joint and second dilatation joint is crisscross arranged, and refractory fiber blanket is layed in some flat wedge refractory brick and is adjacent on the refractory brick of cup dolly and covers second dilatation joint.This anti-equipment structure has overcome the defective that traditional refractory brick combines and builds by laying bricks or stones with mould material, has guaranteed the consistence of chassis refractory materials heater wire velocity of variation and the stability of structure of refractory, has effectively improved silicon steel lumber recovery and chassis work-ing life.
