What problems are prone to occur when the glass kiln is being baked?

PART.01

The anti-corrugation tie rod breaks

Reason: Because the longitudinal expansion is greater than the lateral expansion during the large thermal expansion, the anti-corrugation tie rod is subjected to both tension and shear, which leads to the breaking phenomenon

Handling: Add graphite powder lubrication between the palm iron and the angle steel, directly use the tie rod round steel to make a hook shape, do not leave long holes for the bolts and the connecting beam holes, and replace the spare tie rod in time.

PART.02

The influence of steel structure movement

In this case, timely measures should be taken to avoid greater resistance to the refractory material during expansion.

PART.03

Insufficient expansion joints

Insufficient expansion joints cause damage to the brick structure of the glass kiln. Decisive and timely removal of the insufficient parts to avoid squeezing the gables and hooks, etc., and even the danger of burning the steel plate.

PART.04

Deformation and cracking of the large and small furnace crowns

This is caused by the inappropriate tightness of the tie rods and uneven local temperature control. The measures taken are to check and loosen the tie bars frequently and control the reasonable heating speed to solve the problem.

PART.05

Local or individual top bricks fall down

The reason is that the mud is not evenly applied during bricklaying and the size error of the bricks is large, and the control is inconsistent when driving the lock bricks, resulting in one side being too tight and the other side being too loose, so that the bricks are subjected to inconsistent forces. The measures taken are to lift the fallen bricks with flat pliers, and then clamp them with cast iron sheets, or use silicon hot patching materials to slurry and clamp them after lifting.

PART.06

Cracks in the glass kiln wall

This phenomenon mostly occurs on the side walls of the small furnace and the wall of the heat storage chamber. The solution: Tighten the tie bars of the small furnace wall and the end wall columns in time to avoid vertical cracks in the wall due to expansion. At the same time, the gaps should be filled in time.
