One. The main components of alkaline refractories
The main components of basic refractories are magnesium oxide and calcium oxide, of which the magnesium oxide content is usually greater than 70%, and the calcium oxide content is between 20% and 30%. In addition, in order to improve the melting performance of basic refractory materials, a certain amount of flux will be added, such as kaolin, silicate, etc.
In addition, in order to reduce production costs and improve product performance, basic refractory materials can also be mixed with some other materials, such as lightweight aggregate, alumina, aluminum silicate, etc. These materials can improve the physical and chemical properties of basic refractory materials, and enhance their refractory performance and mechanical strength.
It should be noted that the composition and proportion of basic refractory materials vary according to the manufacturing process and application. In the process of production and application, it is necessary to select the appropriate raw materials and proportioning scheme according to the specific process requirements and use environment to ensure that the quality and performance of the product meet the standard requirements.
Two. Main products of alkaline refractories
1. Magnesium oxide ball
Magnesia ball is a spherical granular refractory material, mainly composed of magnesium oxide and a small amount of flux, with good alkali corrosion resistance and high temperature resistance.
2. Alkaline refractory brick
Alkaline brick is a square brick-shaped refractory material, mainly composed of magnesium oxide, calcium oxide and flux, etc. It is suitable for high-temperature reaction chambers, kilns, heating furnaces and other parts. Basic refractory bricks include magnesia bricks, magnesia-chrome bricks, forsterite, magnesia-alumina bricks, white jade and limestone.
3. Basic fiber
Basic fiber is a kind of fibrous refractory material, mainly composed of magnesium oxide, silicate and flux, etc. It has excellent alkali resistance, high temperature resistance and heat insulation performance, and is suitable for various high temperature heat insulation occasions.
4. Alkaline cement
Alkaline cement is a cement-like refractory material, mainly composed of magnesium oxide, calcium oxide and flux, etc. It is used to connect alkaline refractory components.
It should be noted that different manufacturers and different applications have different requirements for basic refractory products. When selecting and using basic refractory products, it is necessary to choose according to the specific process requirements and use environment, and strictly follow the instructions of the product instructions for construction and maintenance.
