The Protection Measures of Refractory Brick

The protection of the commonly used refractory material has several aspects:

1. Lining cooling

According to the cooling intensity, it will have effect on the life of refractory brick according to all kinds of

mechanism. Cooling system is divided into slagging layer and gradient of slagging, the work surface

temperature is decreased obviously, and has helped the water-cooling system on a certain level, the equivalent

of refractory material and erosion of the interaction of solid state and liquid state product are balance, or  cause

formation of slagging layer conditions. Gradient,  furnace temperature of refractory material is still the same,

and approximately equal to the furnace space temperature, the temperature reduction of cold face, so that the

lining increases  according to the thickness of the temperature gradient, and at a specified level, during furnace

use in a certain period for the water cooling system.

2. The gunning of refractory material lining

On many occasions, gunning can obviously increase the lining life. Develop gunning (cover) can calculate lining

with new sludge (by model) pouring used part without damage. Save raw materials.

3. Reducing erosion of eater

Refractory materials using slag erosion is one of the factors. The contact time of slag and refractory material  is

the longer, the lining damaged is the larger .Test shows that the ladle lining damage and the thickness of slag

layer actually has a linear relationship.



4. Prescribed temperature and gas system quota

Temperature and oxygen of steelmaking production, these important enhancer value, in the final analysis

depends on the economic calculation. The most suitable value of the data carries with the nature of the

compromise.

5. Reasonable refractory material masonry structure

In general, have a relationship with improving thermal shock resistance of lining, because the traditional way is

to the improvement of thermal shock resistance of individual products, often do not guarantee the thermal

shock resistance of masonry. The protection of the masonry of refractory materials is to use a variety of

approaches to prevent damage due to mechanical stress.
