Structural form of refractory material for tin bath top cover

Tin tank top cover generally adopts the structure form of hanging flat top fully sealed, its role is to seal, lifting and installation of electric heating elements and pressure measuring elements, protection of gas pipeline. 
The shell of the top cover is a steel cover, which mainly plays the role of sealing. The space between the top cover and the steel cover is formed and separated into high, medium and low temperature parts, and the protective gas enters from the top of the steel cover. Preheating in this space, and then through the top cover between the combination of bricks into the tank, the combination of bricks on the one hand can pass the protective gas, on the other hand, the tank of electric heating lead wire from the combination of bricks lead out. Tin groove roof cover with protective gas inlet, power line inlet, temperature and pressure measurement components and other holes, the requirements of the material thermal vibration performance should be good, not easy to damage the flaking.

Refractory reinforced concrete roof

In the refractory concrete precast block is equipped with steel reinforcement, the lower surface of the buried heat-resistant steel hooks, used to support the electric heating wire ceramic tube, ceramic tube can be arranged horizontally along the tin groove, can also be arranged along the longitudinal direction; the top cover of the upper surface of the exposed head of bolts, in order to fix the top cover hanging, this exposed Eumenical bolts of the other end of the curved, pre-burying, curved part of the hooks should be the main reinforcement. Refractory concrete roof with three-phase silicon-carbon rods, the lower surface does not need to be pre-embedded porcelain pipe hooks, between the two rows of roof, install three-phase silicon-carbon rods.

Refractory brick roof

The roof is assembled from many small refractory bricks. In these bricks, the beam brick is load-bearing, usually with heat-resistant steel parts to hang it on the sealing cover; bridge brick is basically not load-bearing, which is set up in the two rows of beam brick above; in the gap between the beam brick and the bridge brick, placed in the roof brick or silicon-carbon rod support brick.
