Fire Clay Runner Brick

Fire Clay Runner Brick is mainly made of calcined Scorched Gemstone and clay. It is formed by the reformed press and fired in a tunnel kiln at 1300 ℃, and it has good high temperature resistance, impact resistance, erosion resistance and corrosion resistance of molten steel. It is widely used in the casting process of molten steel and molten iron in steel plants and foundries.

Description

1. Features of Fire Clay Runner Brick:

1) Good compactness, suitable for flowing of molten steel and molten iron

2) It is suitable for the casting process of molten steel and molten iron under 1300 ℃

3) It has better erosion and erosion resistance of molten steel and molten iron

4) 1-2 times of use

2. Application of Fire Clay Runner Brick: Casting of molten steel and molten iron

Fire Clay Runner Brick is the most common steel pouring brick, which is a common refractory casting product in common casting process of steel plants and foundry plants. It is composed of funnel, round pipe, center, square pipe, elbow and tail brick type brick, so that the steel flow in the middle channel and cast into billet products. In the production of cast-in-place steel brick, it is required that the adhesive of binder is better, the particle size ratio should be scientific, and the molding performance of the mixture is good. In this way, the strength of the product after forming can be good enough. Meanwhile, the weak oxidation atmosphere shall be adopted during the firing process, and the performance of the product will be more excellent
