Electric arc furnace---how to choose the best one

To choose a good vacuum arc furnace suitable for their own use needs to start from the following aspects:  

1. Shell: vacuum electric arc furnace with high quality steel profile, plastic spray color surface, pleasing to the eye, heat resistance and corrosion prevention.  Do not choose thin sheet iron shell, that kind of electric furnace deformation and short service life.  

2. the circuit design must be reasonable.  

3. The furnace type of vacuum electric arc furnace should be light and easy to handle for convenient use. If the furnace type is too large, when buying, ask the manufacturer to install wheels to facilitate the movement of the electric furnace.  

4. When choosing vacuum electric arc furnace, we must choose a vacuum electric arc furnace with high temperature control accuracy, so as to ensure the production and experimental quality of items.  

5.the choice of vacuum arc furnace furnace material, need to choose high temperature resistance, good seismic performance, heat and cold resistant material.  

6.temperature measuring element: choose gb model thermocouple for temperature measurement, this thermocouple temperature measurement is more accurate, and the service life is long.  

7. heating element: the choice of heating element is also very important, must choose good quality, no deformation, do not drop slag heating element, otherwise affect the service life of vacuum arc furnace.  It also affects the firing quality of items.  

What kind of vacuum arc furnace is easy to use  

Vacuum arc furnace is widely used in the production and experiment of various industries, such as alloy steel products, various metal parts normalizing, quenching, annealing and other heat treatment, or diamond cutting blade, ceramic products for high temperature sintering purposes, can also be used for gold smelting ash blowing and other processes,  Related to the industry of ceramics, metallurgy, electronics, glass, chemical, machinery, refractory, new material development, special materials, building materials and other fields of production and experiment.  

Check the connection of electric furnace and controller regularly.  The furnace and controller must be operated in a place where the relative humidity does not exceed 85% and is free of conductive dust, explosive gases and corrosive gases that can destroy metal insulation and electronic components.  The operating temperature of the controller is limited to 0-50 ° C.  When the electric furnace and controller are used, the rated power shall not be exceeded, and the furnace temperature shall not exceed the service temperature. It is forbidden to load the damp workpiece into the furnace, and the heated workpiece containing ultra high moisture shall be dried in advance.
