recently, the patent of “preparation method of new environmental protection high express-melting silicon content” was invented independently by harbin dongsheng metal materials co., ltd. which successfully passed review of and was granted authorization by china’s state intellectual property office.
the patent which serves as a powerful representation of ability of independent innovation is invested after taking hundreds of tests and overcoming various difficulties by r&d team led by wang chunyang, the general manager of this company. the invention mainly resolves the issues of environmental pollution which has an effect on human health in existing express-melting silicon, low recovery efficiency while oxidizing silicon with high temperature, high energy consumption or long melting. the recovery efficiency of the new express-melting silicon is more than 90%, which is easy to obtain silicon alloy with even and proper content and supplies the domestic gap in such field
in recent years, the company constantly takes measures to protect independent intellectual property, to improve management system of intellectual property, draft method for employees reporting patent reward, set up special fund to make reward, motivate the employees’ vigor in independent innovation. the intellectual property and products with patent which the titles to the company have become the competitive products and take advantage of independent intellectual property of leading products.
