The reason for the decline in the quality of refractory castables

1. Regarding the quality of refractory castable construction, there are four main points to focus on: the planning and construction quality of the anchor, the moisture content of the castable during construction, the temperature at the time of construction, the post-maintenance and the baking of the refractory castable grilled.


2. In the process of mixing the castable with water, the amount of water added is crucial. For example, if the amount of water added is too large, the castable will appear relatively thin, and the fluidity will increase, which will affect the construction strength of the castable. However, if the amount of water added is too small, it will cause the aggregate and the powder to be difficult to mix and cause accumulation, which will result in loose structure and deteriorating construction quality.


3. The important factor in the quality of the castable is the temperature. Short-term sudden changes in temperature can cause the castable to be damaged quickly, and then the quality will be seriously degraded, and even if it is not used, it will fall off. The thermal shock sta   bility of the castable is very weak before construction is completed.


4. Cement dosage, cement is an important material to determine the strength of refractory castables. Generally speaking, with the increase of cement dosage, the normal temperature compressive strength increases, the high temperature strength decreases, the refractoriness and load softening temperature decrease continuously, and the line shrinks after burning. The rate also increases. Some manufacturers will shoddy the product, causing the castables to fail to meet expectations.

Silica Ramming Mass --- Ruizhi Refractory

Silica ramming mass also known as acidic ramming mass.The raw material of silica ramming mass is high quality quartz, mixed with high quality boric acid. Silica content of its raw material is more than 99%. Generally we will add 1 % to 1.5 % to premix with quartz, but it can be changed as per customers’ requirements. Silica ramming mass is one of the most popular products in our company.

Plays a crucial role in induction furnaces during melting of steel. This substance is used to line induction furnaces and its quality decides smooth working and more efficient output from the furnace.

Our monthly production capacity is 10,000MT/month.

Advantages of Silica ramming mass:
High erosion resistance.
High bonding strength.
Free engineering services to guarantee service life.
Does not expand or shrink with temperature changes

High Alumina Brick, Alumina Brick --- Ruizhi Refractory

High alumina brick is a kind of neutral refractories. It is manufactured from bauxite or other refractory raw materials within high alumina formed by molding and calcination. High aluminum refractory bricks has high refractoriness, high load softening temperature, thermal shock stability, good slag resistance, acid, alkali, peeling resistance, erosion resistance and so on.

High alumina brick is mainly used for electric furnace top, blast furnace, hot air stove, ladle, cement kiln, glass kiln and other thermal furnace lining. High alumina brick is widely used in iron, steel, chemicals, cement and other industries.
