Background

Silicon carbide has many other uses besides abrasive materials, such as: silicon carbide powder is coated on the inner wall of the impeller or the cylinder body of the water turbine by a special process, so that the wear resistance of the water turbine impeller or the cylinder body can be improved, and the service life of the water turbine impeller or the cylinder body can be prolonged by 1-2 times; the high-grade refractory material has the advantages of heat shock resistance, small volume, light weight, high strength and good energy-saving effect. In the production of reaction sintered silicon carbide products, cutting is required according to the size of the products, and thus a cutting device is required.

Based on the above, the inventors believe that although the existing reaction-sintered silicon carbide cutting devices are diverse, the following disadvantages are found to still exist when in use:

1. most of the existing reaction sintering silicon carbide cutting devices are of single saw head cutting structures, and for reaction sintering silicon carbide products with the same length which are required to be cut in a large batch, the two ends of the products are required to be cut twice, so that the efficiency is low;

2. the saw blade of the saw head cuts the product for a long time, so that the saw blade is easy to become blunt, and the cutting effect is reduced, so that the saw blade can be continuously used after being detached for replacement or detached for polishing, and the use is inconvenient;

we have therefore proposed a cutting device for reaction sintering silicon carbide to solve the above-mentioned problems.
