Phosphate Bonded High Alumina Bricks Classification & Difference

Phosphate High Alumina Bricks Classification

Phosphate brick high alumina bricks are divided into phosphate bricks and phosphate wear bricks.

Phosphate High Alumina Bricks Difference

❉Phosphate brick is used as a binder for phosphate, and phosphate wear-resistant brick is a binder of diammonium phosphate.

❉Generally divided into resistant phosphate and high temperature phosphate. These two bricks are not much different because phosphates have better wear resistance.

❉High-grade phosphate bricks are high-load soft phosphate bricks. Because phosphate bricks are combined with phosphoric acid, the load is generally low. Above 1300 ℃ ~ 1450℃.

Refractory Gunning for Mixer Furnace Manufacturing Process

1. Determine the refractory raw materials used in magnesium spray coating according to the formula to ensure the quality of raw materials.

2.Calculate weighing ingredients according to the formula, control the size and proportion of aggregate and powder particles, and strictly calculate the ratio of raw materials, additives and usage.

3. Place the prepared powder and aggregate first in a blender and mix for about 5 minutes. Then add the powder to the aggregate and mix it evenly for 8-10 minutes.

5. The gunning mix refractory is equipped with additives and binders, and then stored in the warehouse.

Refractory Gunning for Mixer Furnace Installation Procedure

1. Before the construction, the concrete surface should be degreased and decontaminated.

2.Paint mixing: according to water: paint = 100:120 ratio of ingredients. First, add water to the paint and mix it evenly. The finished paint should be used up within 2 hours. Due to different construction tools and weather conditions, water can be added as appropriate.

3.Construction method: The construction should be carried out above 5 °C. The first road should be sprayed, the thickness is about 3-5mm, and the thickness of each time is about 3-5mm until the fireproof design requirements are met. The interval between each construction is not less than 24 hours.

4.Surface decoration: If refractory gunning construction, the appearance of the coating is a uniform granular surface, which has a sound-absorbing function, generally not to be smoothed. When it is necessary to smooth the treatment, it should be done after the tail spray. When there are surface decoration requirements, other decorative materials can be sprayed (brushed) on the surface of the fireproof coating.

Anhydrous Stemming Application
 
1.Refractory anhydrous mud can be used in the taphole and slag mouth of the blast furnace
 
2.Anhydrous stemming for blast furnace can also be applied to the iron mouth of the ore furnace.
 
Anhydrous Stemming Using Instructions  
 
1.Refractory material anhydrous stemming can be used in the blast furnace tap and slag mouth, and can also be applied to the iron furnace of the mine furnace.
 
2.Anhydrous stemming for blast furnace is divided into two types: one is normal waterless cannon mud, mud gun thrust greater than 12MPa can be directly preheated,the other is soft waterless cannon mud. Soft cannon is specially prepared for small thrust mud cannons.
 
3. Refractory anhydrous mud is heated and preheated properly during use, while the soft waterless cannon is heated without preheating.
 
The whole process of refractory material anhydrous stemming should be in a waterless environment.
 
Anhydrous Stemming Operation Instructions
 
1.As shown in Figure 1,refractory material stemming is placed in the iron mouth 2 hours in advance, the baking on both sides of the slag mouth is preheated to ensure that it can reach 50 ° C - 100 ° C, 70 ° C before loading. The best is left and right.
 
2.Put refractory material anhydrous stemming into refractory mud cannon before each opening, the principle is to fill it up.
 
3.the opening is normal iron, after the slag, the front end of the mud gun with the refractory mud can be displaced to the iron by 500 mm, the top of the slag mouth (about 500 mm) is naturally baked for about 5 minutes, then squeezed out slightly. stand-by.
 
4. when blocking the mouth, all the mud should be driven in, the top shot time is about 15 minutes, you can spray water around the iron, slag mouth to cool down.
 
5.Refractory bricks should be returned immediately after the return of the gun, refractory mud gun piston is loaded into the soft cannon 20 kg, and the remaining gun mud in the mud gun, and confirmed to be used.
 
6.When loading the preheated cannon mud next time, squeeze out the soft waterless cannon in front of the refractory mud cannon. Soft cannon is reusable. Please carefully grasp the residual amount of waterless cannon in the refractory mud gun for each operation, the less the better (because the soft cannon can not be used as the normal gun mud of the iron slag mouth).
 
For each operation, please check the coking condition of the gun. If coking is found, please clean it with steel brazing immediately.
