Q:does the electric kiln burner need to be sealed?
seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
The furnace arch and the furnace wall are all refractory bricks, and the refractory brick is a kind of thermal insulation material!
Q:how to test the high alumina refractory brick mixed alumina?
The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
Q:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
use ceramic fiber precast block
Q:Small size black brick can replace refractory bricks for wood burning fireplace?
No, because the melting point of the black brick is only more than 700 degrees, will flow. But that of refractory brick is above 1200 degrees. It mainly depends on the peak temperature, because the fire area of rural cooking range is small.
Q:How to use the winding packaging machine to pack refractory bricks
Over 150KG the most common winding machine can pack, if it is light or the goods scatter, then add capping or pre-drawn device is all right.
Q:Do refractory bricks resist corrosion and sulfur?
There are anticorrosion and acid proof refractory bricks
Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
Withstanding voltage strength is not the same, the strength of the mechine-made is higher
Q:How can refractory bricks be punched?
Electric is ok
Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
Refractory mortar
