The gas melting machine is a professional sample preparation equipment developed by Ruishenbao Analysis Technology (Shanghai) Co., Ltd. for X-ray fluorescence analyzer (XRF) - glass melting plate method analysis and testing. The process of preparing XRF test glass melt by glass melting method is as follows: the sample is assisted by a flux (borate: generally a single or certain proportion mixture of lithium tetraborate and lithium metaborate) and a release agent (mostly halide), and a platinum yellow crucible (generally a platinum/gold mass ratio of 95/5) is used as a thermal conductivity container. The glass melt is melted by high temperature heating (the melting temperature of the sample is generally between 1050 ℃ -1300 ℃), and finally cooled directly at the bottom of the pot or cast mold to form the glass melt. As one of the sample preparation methods for XRF testing, the glass melting method effectively reduces the matrix effect and mineral effect of minerals such as ore, rock, soil, refractory materials, and metallurgical raw materials during XRF analysis, greatly improving the accuracy of analysis. It can be widely used in industries such as steel, metallurgy, chemical engineering, geology, cement, ceramic refractory materials, etc. This automatic melting machine is a fully automatic 4-head gas melting machine with a compact structure. It uses gas (propane or butane) to melt the sample, with fast heating speed, automatic temperature control, good temperature control accuracy, PLC automatic control, and multiple safety protections designed to ensure safe use of gas. The whole machine has superior performance and high cost-effectiveness.

advantage

Advanced design concepts have been applied, resulting in a small size and beautiful structural appearance.

Adopting a four head fully automatic gas melting design, heated with LPG (propane/butane), the heating speed is fast, and the temperature setting range is wide (800-1600 ℃).

Each head can be independently controlled, and each heating head can display independently.

High temperature stability, good reproducibility, and can be individually set to run 1, 2, 3, or 4 heating heads.

Throughout the entire melting process, the forming mold is heated independently, greatly extending the service life of platinum.

PLC automatic control, high degree of automation, can set parameters such as rotation, swing, sample pouring, pause, time, and speed, achieving one click operation.

Set up a hierarchical authorization mechanism (for technical engineers and experts) to meet the needs of laboratory equipment hierarchical management.

The design includes safety mechanisms such as emergency shutdown, gas leak shutdown, overheat protection shutdown, flame control unit locking, temperature sensor flame control, etc. The LED displays the operating status throughout the entire process, and multiple mechanisms ensure equipment stability and personnel operation safety.

With high sample preparation efficiency and excellent melting quality and stability, it can also meet the requirements of XRF experiments, and the overall cost-effectiveness of the machine is superior.
