What Are the Protection Measures of Refractory Brick ?

Date:2017-08-16 10:19 | From:Zhengzhou Sunrise Refractory | Author:admin

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 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


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.
