来金船中的筛板是易损件。目前,我国正在服役的百艘50至100H采金船,其筛板的使用周期仅一年左右,主要损坏形式是磨损。为解决寿命低的问题,我们从筛板的热处理设备和工艺等方面进行了一些试验,研制成了采金船筛板专用井式电阻炉。能够保证筛板的热处理质量,使其使用周期达到两年以上。 Sieve to the gold ship is wearing parts. At present, China is serving a hundred 50 to 100H gold mining vessels, the sieve plate life cycle of only about one year, the main form of damage is wear and tear. In order to solve the problem of low life expectancy, we carried out some experiments on the heat treatment equipment and technology of the sieve plate, and developed a special pit type resistance furnace for the gold mining vessel sieve plate. Sieve can guarantee the quality of heat treatment, the use of the cycle to achieve more than two years.
