At present, the comprehensive performance of the domestic Chinese quarry wire saw is close to the international advanced level, and the cost is low, which can fully meet the needs of the domestic stone mining and board processing industry. Even the wire saw products produced by many companies have begun to be exported to Europe, America and other Western countries. nation. With the rapid promotion and use of quarry wire saw machinery and quarry wire saw cutting technology, my country's stone block mining has entered the era of quarry wire saw, and quarry wire saw manufacturing enterprises have achieved unprecedented development.
With the growth of quarry wire saw usage and the continuous expansion of applications, the production technology of quarry wire saw is also constantly improving. In order to comply with the rapid development of domestic and foreign markets and catch up with the international advanced level, some domestic companies in recent years Continuously introducing new equipment and researching and applying new technologies. While the scale of production continues to expand, product quality and production efficiency have also been greatly improved, while production costs have continued to decline.
China quarry wire saw tells you that diamond bead sintering is an important link in the production of quarry wire saw, which directly affects the cutting performance of the wire saw. Beads are cylindrical thin-walled structure, which requires high sintering density. The usual hot-pressing sintering method directly limits the sintering density of beads due to the thin wall of the upper and lower indenters and poor pressure capacity, and the loss of the indenter is large and the cost is relatively high. high. In the traditional method of cold pressing and then pressureless sintering, the sintering density of the beads is lower, which seriously affects the performance of the wire saw. China quarry wire saw tells you that the most effective sintering method is to use hot isostatic pressing (HIP) technology. The application in the production of beads is to put the sintered beads in the glass sleeve (some companies do not put the glass sleeve, directly Put it in a hot isostatic pressing sintering furnace), put it in a hot isostatic press, use inert gas Ar as the pressure transmission medium, and raise the temperature to 800℃~900℃ for isostatic pressure treatment, and then use roller treatment or spray Remove the glass cover by pill treatment. China quarry wire saw tells you that the beads produced by this technology have fewer pores and high density, which can improve the hardness, strength, wear resistance and working life of the beads, and can also improve the bonding strength between the matrix and the carcass; due to the furnace The cavity is large, thousands of beads can be installed at one time, which is conducive to mass production.
