Abstract
The present invention relates to a wear-resistant scraper used in a disc ball making machine of a sintering machine in metallurgy industry, which is characterized in that a wear-resistant layer made of wear resistant materials is poured at the head of a round steel. The wear-resistant materials are composed of solid materials and liquid materials whose weight percentage is equal to the sum weight percentage of the added solid materials, wherein the solid materials comprise 30 to 50 parts by weight of silicon nitride, 40 to 60 parts by weight of zirconia corundum and 1 to 2 parts by weight of white carbon black, and the liquid materials comprise 1 to 2 wt% of accelerant, 0.5 to 1 wt% of coupling agent, 2 to 4 wt% of toughening agent and 6 to 8 wt % of solidifying agent. The present invention has the manufacturing method that the head of a round steel is formed by pouring and shaping the wear-resistant materials. After the solid materials, a chemical combined agent, the accelerant, the coupling agent and the toughening agent are uniformly mixed according to the proportion, the toughening agent is poured in and start to cure to discharge heat quantity at normal temperature within 30 minutes. Curing strength is increased in four hours and demoulding is carried out. The present invention has the advantages that wear-resistant effect is good, service life is more than 6 months by being increased by three to four times, efficiency can be improved by 300% and the Mohs hardness can reach 8.5 to 9.
