Development of Composite grate 1. Grate strength composite materials after Shisu covers. The vehicle can carry more than 40 tons. 2. Its overall performance between Shisu covers and concrete covers, better than concrete; covers technology can be applied to situations requiring high. 3. Grate the most outstanding advantage of composite materials is not using steel skeleton reinforced, and to glass fiber reinforced composite price rainwater grate, belong GRC products. Therefore, it is in the case of continuously rising prices of steel, more benefits will not be affected. Because it does not contain iron, which is more security than Shisu and fiber reinforced concrete covers. 4. Grate composite fiber concrete curing speed several times faster than 8 hours stripping, if three shifts, 24 hours a release three times, although the amount of more than Shisu die, but only fiber reinforced concrete covers 1 / about 6, can also reduce mold investment. It covers annual million sets, 10 sets just die. 5. Grate Composite is the best, more advanced, other molds can not be compared. 6. Composite grate in continuous improvement and update of the indicators have exceeded the Ministry of Construction industry standards, basically reached the national standard. J506 milling of cast iron can be used to weld from the intensity level, the pure nickel 308 is not the best choice, considering the comprehensive strength of the crack and, in particular, the effect on cracking it can refer to the use of special cast iron WE777 cold welding electrode welding process the most insurance, after all, just a broken repair, not much of engineering, suggested a number of special safety timber repair. In addition, when the broken parts in the repair weld must be prepared to handle breakage, such as cracking or fatigue need to be polished off, so as to solve the problem fundamentally, in accordance with what WE777 some use cases ductile iron determination can be soldered, this should in some of the high-strength cast iron equipment use more, under normal circumstances be higher tensile strength ductile cast iron rainwater grate role in the weldability is worse than gray cast iron welding, cast iron equipment we repair the fact it is difficult to distinguish with the naked eye is gray cast iron or ductile iron, we usually use the versatility relatively wide WE777 special cast iron electrode welding rain grate types, but only for use in the repair service, the effect is indeed Well, reducing the risk of cracking and high strength welding rod matches to ensure the strength of the weld itself. WE777 special applications for the full range of cast iron electrode welding cold welding process, can weld almost all the cast iron base material, and easy to implement dissimilar welding of cast iron and steel, to solve such as the matrix breaks, cracks, wear, fill the hole defects, welding After completely machined, many occasions in the engine housing, the cylinder head, the machine base, casting gear teeth and other various pieces of iron. Technical data Tensile strength WE777 special cast iron welding rod: ≥70,000 PSI (≥482 N / mm2) Yield strength: general 62,000 (≥427 N / mm2) Hardness (HB): 185HB and base metal colors : similar power options: AC and DC, DC reverse current when rain grate, rain grate plant, WorldCom iron (certified merchants) are provided by Daiyue Tai'an City WorldCom iron factory.
