The demand of nodular cast iron grate is increasing constantly. We should ensure the quality of the product on the premise of improving production efficiency. In order to give full play to the better performance of the product, we should pay attention to the use of the grate. In the process of using, we must pay attention to its wear resistance and corrosion resistance. Today's edition will introduce the wear resistance of nodular cast iron grate in detail. Method:
1。 In order to protect the back of nodular cast iron grate from erosion at the bottom, the back of nodular cast iron grate is effectively protected。 The grate is thickened by 3-5mm and epoxy resin E44 is used as the anticorrosive coating。 Because E44 epoxy resin or other synthetic resins have good corrosion resistance。
2. The surface of nodular cast iron grate is wear-resisting layer. It is made of an unsaturated polyester epoxy resin with aging resistance, acid resistance, alkali resistance and ultraviolet resistance, and 80-120 mesh artificial corundum sand, iron powder or diamond sand are added into it. Using the super high wear resistance of artificial corundum sand, iron powder and diamond sand and the cementation of resin, the nodular cast iron grate has ideal wear resistance. Because diamond and corundum are materials for making grinding wheels and abrasive cloth, they are more wear-resistant than cast iron.
3. In order to improve the overall mechanical strength of the product, a 4-5 degree arch design is adopted. The bottom of the metal derrick is strengthened and combined with the casting of the cap to overcome the defects of product deformation and light weight.
4。 In the joint of nodular cast iron grate and nodular cast iron grate seat, a placement buckle was designed。 In order to prevent the accident of flying off the ground at high speed, the manufacturers of nodular cast iron grate set the edge of nodular cast iron grate symmetrically to 2-4 buckles, and the corresponding position of nodular cast iron grate seat to L-shaped buckle socket, using special tool handle。 After the manufacturer of nodular cast iron grate is placed on the nodular cast iron grate seat and rotates at a certain angle, the nodular cast iron grate is buckled together with the nodular cast iron grate seat to reduce the number of traffic accidents caused by the existing nodular cast iron grate flying off the ground。
The improvement of wear resistance of nodular cast iron grate not only improves the quality of products, but also guarantees the safety of vehicles to a certain extent. Our company pays great attention to the quality detection, strictly enforces the production requirements with higher standards, and the product quality fully meets the national quality standards.
