Advantages Of Monolithic Refractory Materials In Steel Making

Date:2016-07-01 18:04 From:Zhengzhou Sunrise Refractory Author:sunrise
The steel industry consumes a large amount of refractory materials and a variety of refractory mayerials are involved. 1,000,000 tons of refractory materials are required to produce 100,000,000 tons of steel. The quality of refractory materials is very important for the quality of steel and the service life of equipment. 
Monolithic Refractory Materials
Based on the shapes, refractories can be divided into shaped refractories, monolithic refractories and ceramic fiber products. Monolithic material are a type of loose mixtrue made of aggregate and powder as well as binding agents and addtives. It can be used without calcinating. According to the requirements of high temperature construction, add an appropriate amount of liquid and stir uniformly. Then finish the construction by molding, drying and firing at low temperature. It has incomparable advantages over the traditional refractory materials. 
 
1) Energy saving
Since there is no firing process and only molding, drying and baking, its energy comsumption is only 5-6% of that of the fired refractory bricks.
2) High production efficiency
Since the manufacturing process is simple, its production efficiency is 4-9 times than that of the refractory bricks. 
3) High construction efficiency
Its construction efficiency is 6-15 times than that of the refractory bricks.
4) Flaxible shaping
It can be not only made into integral shaped lining but also used for the rapid repair of kilns. It can improve the service life and work rate.
5) Wide application
It can be used in various high temperature projects. 
 
Based on the construction method, monolithic materials can be divided into castables, plastic materials, ramming mass, spray materials and refractory mortar. Since 1970s, the consumption of plastic materials and ramming mass decreases, while the consumption of castables and spray materials increases year by year. Currently, the castables account for 50% of the monolithic materials and the spray materials 20%. the reasons why the consumption of castables and spray materials increase is the simple construction and constant upgrading of materials and performance. Its properties and service life is beyond that of other refractories with the same materials. 
 
The monolithic castables can be directly used at site or made into preforms. The monolithic spray materials can be used spray gunning material and spray coating material. The spray gunning material can be used for the lining repair and the spray coating material can be used to build new linings.
