High Alumina Refractory Ramming Mass Definition
The high aluminum refractory ramming mass is made of aluminum bauxite clinker as aggregate and powder, adding refractory clay. then adding a proportion of the unshaped refractory material prepared by the binder, refractory high alumina ramming mass is constructed by manual or mechanical beating. After the construction, heating is performed to harden it to form a lining to resist slag erosion.
High Alumina Refractory Ramming Mass Features
1. High aluminum refractory ramming mass generally require high volume stability, compactness and erosion resistance, the ramming material used for induction furnaces should also be insulating.
2. High alumina refractory ramming have strong resistance to slag erosion.
3. Refractory high alumina ramming mass have high temperature resistance.
4. High alumina refractory ramming have the load softening temperature is high.
5. High aluminum refractory ramming mass have good thermal shock resistance

High Alumina Refractory Ramming Mass Application
1. Alkaline refractory ramming mass mainly used as the inner lining of the electric furnace and the bottom of the furnace and the packing of the converter lining.
2. Acid ramming refractory mass mainly used as lining of power frequency induction furnace, lining of glass furnace kiln bottom.
3. Neutral ramming refractory mass mainly used as burner and lining for induction furnace, heating furnace and soaking furnace.
4. Containing silicon carbide, silicon nitride and carbon refractory ramming mass, refractory ramming is mainly used as the iron lining of various large, medium and small blast furnaces.
High Alumina Refractory Ramming Mass Manufacturing Process
The main raw material of high aluminum refractory ramming is high-grade high-alumina bauxite clinker. The general granule is 8mm. The base material is usually made of first-grade bauxite powder or fused corundum powder. The particle size is larger than 0.088mm and less than 4mm. In order to increase high aluminum, the plasticity of the ramming refractory mass is then added to the refractory clay, the mixture is stirred and mixed for 16 hours according to the ratio. When used, water or other liquid is added according to the situation. In the production of high-aluminum crucible, the raw material particle size ratio is: coarse, medium and fine = 20:40:40, and then 12%-14% of the binder is added.
High Alumina Refractory Ramming Mass Construction Method
1. High Alumina Ramming Mass stirring
First put the proportioned ramming material into the mixer, then add a certain amount of water or additives and stir evenly for 5 minutes.
2. High Alumina Ramming Mass Construction
The mixed ramming material is laid once and has a thickness of 80-100mm. High alumina refractory ramming is continuously and evenly beaten with a pneumatic hammer to achieve the required thickness of the lining.
