Operation skills and maintenance of fire assay ash blowing furnace

Fire assay ash blowing furnace is a traditional metal material analysis method. Operation skills and maintenance are the key to ensuring accurate analysis results and long equipment life. This article introduces the operation skills and maintenance methods of fire assay ash blowing furnace.

1. Operation skills of fire assay ash blowing furnace

1. Sample preparation: Sample preparation is the key to accurate analysis results. The sample must be dry and uniform powder, and impurities in the sample must be avoided.

2. Cleaning the furnace body: Cleaning the furnace body is the key to accurate analysis results. Before each use, the inside of the furnace body must be cleaned to avoid sample contamination and the influence of impurities inside the furnace body on the analysis results.

3. Furnace heating: Furnace heating is the key to accurate analysis results. The furnace body must be heated evenly and must not be overheated to avoid affecting the analysis results and the life of the furnace body.

4. Airflow adjustment: Airflow adjustment is the key to accurate analysis results. The airflow must be stable and must not be too large or too small to avoid oxide blowing or inaccurate analysis results.

5. Purge time: Purge time is the key to ensure accurate analysis results. Purge time must be accurately controlled. Too short or too long will affect the analysis results.

II. Maintenance of fire assay ash blowing furnace

1. Cleaning the furnace body: Regular cleaning of the furnace body is the key to ensuring accurate analysis results and long furnace life. After each use, the inside of the furnace body must be cleaned and regularly cleaned and maintained on a large scale.

2. Replacement of consumables: The consumables of the fire assay ash blowing furnace include the blowing furnace, heating wire, ceramic pad, etc., which must be replaced and maintained in accordance with the manufacturer's requirements to ensure stable operation of the equipment and accurate analysis results.

3. Maintain the heating system: The heating system of the fire assay ash blowing furnace is the key to ensuring accurate analysis results. It must be regularly inspected and maintained to ensure the service life of the heating wire and uniform heating of the furnace body.

4. Gas line maintenance: Gas line maintenance is the key to ensuring accurate analysis results. It is necessary to regularly check the gas source pipeline, pressure gauge, regulator and other equipment to ensure that the gas line is unobstructed and the pressure is stable, and replace damaged parts in time to avoid gas line failure affecting the analysis results.

5. Maintenance and leak detection: The fire assay furnace requires the use of reducing agents and gases during the analysis process. The equipment must be regularly inspected and maintained to prevent the leakage of reducing agents and gases from affecting the analysis results and the environment.

III. Safety precautions for the fire assay furnace

1. High temperature of the furnace body: When using the fire assay furnace, the furnace body will generate high temperature. Care must be taken to prevent safety accidents such as burns or fires.

2. Oxide hazard: The fire assay furnace will generate oxides during the analysis process. Care must be taken to prevent the inhalation and dispersal of oxides to avoid harm to the human body and the environment.

3. Gas leakage: The fire assay furnace uses gas as a heating source. Equipment such as gas pipelines and valves must be regularly inspected to prevent gas leakage from causing safety accidents.
