Extension of new series and application of diamond wire saw

1. new series of diamond wire saw

Compared with the traditional diamond wire saw (diameter is generally 58-512 mm), a new series of diamond wire saw is formed with the application of small diameter diamond wire saw (bead diameter is generally 55.5-57.5 mm). It is mainly used in the field of strict requirements of slot size.

At the same time, the decrease of bead diameter is very important for cutting precious stones. The application of small diameter diamond wire saw in stone processing, on the one hand, saves stone resources, on the other hand, reduces processing energy consumption, making the processing means more environmentally friendly. In order to meet the market demand, some domestic companies have now produced a variety of specifications of bead string rope, the smallest diameter has been able to achieve 56.0. To reduce the size of wire saw, it is necessary to reduce the diameter of wire rope core and diamond beads. The diameter of wire rope used in wire saw is generally only 53.5-53.8 mm. Due to the reduction of cutting resistance, small diameter diamond wire saw can cut large area (4 square meters) and thin granite plate with thickness (5mm), and the cutting efficiency is increased by three times. The cutting force and energy consumption of the small diameter wire saw are about 20% - 30% less than those of the 59 mm wire saw, and the cutting time per square meter is about 25% less. The material size deviation produced by small diameter wire saw is smaller than that of large diameter diamond wire saw, so it has some special properties. At present, it is better to adopt hot isostatic pressing (hot isostatic pressing sintering after cold pressing) or brazing diamond for small diameter beads. Reducing the diameter of Diamond Beads is beneficial to increase productivity and reduce production costs, and has the advantages of low noise, less pollution and low energy consumption.

2. new application progress of reinforced concrete cutting wire saw

At present, the domestic steel coagulant wire saw technology has developed to a relatively mature stage, the actual scope of use is expanding. In addition to the traditional reinforced concrete structure cutting, it also has large-scale applications in submarine cable cutting, oil pipeline cutting, large-scale steel and other metal structure cutting, boiler and smelting furnace transformation and other fields. For example, the cutting wire saw and matching equipment for submarine oil pipeline and cable pipeline developed by Harbin Engineering University and a domestic company have been applied on a small scale, and the diamond wire saw has been widely used in the smelting furnaces of domestic large and medium-sized steel enterprises, such as Shanghai Baosteel and Guangxi Liugang. The advantages of simple operation, environmental protection, and strong cutting ability of parts can save a lot of transformation cost for enterprises.




Compared with other diamond tools, diamond wire saw is a flexible tool, which can be used not only for cutting straight plates, but also for cutting special-shaped plates; it is not limited by the shape of the object surface, the worksite requirements are simple, can be used for large-area cutting; the use of diamond wire saw can improve resource utilization and reduce environmental pollution. Because of these advantages, its market scale is bigger and bigger, and its application scope is more and more extensive. With the development of technology, the production efficiency of diamond wire saw can be greatly improved by using powder granulation technology and automatic cold pressing technology, and the comprehensive properties and properties of wire saw can be greatly improved by adopting new technologies and methods such as hot isostatic pressing technology, diamond directional arrangement technology, brazing technology, etc. The large-scale use of diamond wire saw is of great significance to improve the utilization rate of stone resources, reduce the cutting cost per unit area and protect the ecological environment.
