High Level Metal Silicon Barium

The continuous determination of calcium and barium in silicon-barium alloys is usually performed using EDTA titration for calcium and the gravimetric method for barium using barium sulfate. The analysis cycle is quite long and is not suitable for pre-furnace analysis. The solubility product differences caused by the precipitation from the reaction of barium and calcium with potassium dichromate are substantial.

1.A screening device for silicon-barium alloy production includes a body, and a filter mesh is movably connected inside the body. The new design utilizes a combination of the filter mesh, a fixing plate, and a limiting mechanism. The limiting mechanism allows for the fixation of the positions of the fixing plate and the filter mesh, making it easy to disassemble and install the filter mesh. This convenience helps users to replace the filter mesh after it gets damaged. It addresses the problem faced by existing screening devices for silicon-barium alloy production, where during feeding, materials directly drop onto the top of the filter mesh. Over prolonged use, impurities on the filter mesh can clog the pores, and the filter mesh may also wear severely, leading to a decrease in screening efficiency. This silicon-barium alloy production screening device has the advantage of facilitating the replacement of the filter mesh, making it worth promoting.
