High Strength Ductile Iron Grate Gully Spray Paint For Sewer Outlets 20kg To 30 Kg

Overview:

The ductile iron rainwater grate is made of a circle. Using mathematical knowledge points to analyze it, it takes advantage of the fact that the diameters in the same circle are flat. Only the circular manhole cover cannot find the diagonal line. When vehicles and pedestrians pass by, its diameter will be wider than the manhole below, and the manhole cover will not fall into the manhole. This not only ensures the safety of vehicles and pedestrians, but also prevents accidents if there are construction workers at the bottom of the well. In addition, because the cylindrical shape can withstand the pressure of the surrounding land. Round objects are evenly stressed. The sewer outlet should leave enough space for one person to pass through, and the cross-section of a person climbing down the ladder is basically a round ductile iron

Production Description:

Manufacturing Process

Raw material → melting in the furnace → Refining refined iron → Refined iron into barrels Pouring → Cooling demolding → Polishing and sanding → Anti-rust paint finish→ Store

We have three advantages in the industry that peer foundries do not have or do not have:The spheroidization rate of cast iron alloy reaches more than 3 times the national standard, and can continue to increase the spheroidization rate according to user needs;
Before the product is dipped in paint, it goes through multiple processes such as vibrating sand-shaking bed and shot blasting machine to remove sand. The probability that the product needs to be returned to the furnace for remanufacturing due to unqualified sand attached to the surface is less than 8 out of 10,000;
The paint impregnated and applied to the product is high-quality and high-resistant asphalt paint, which further improves the service life and wear resistance of the product.
