    Melting and Holding Furnace supply from Huitai




    This continuous aluminum melting and holding crucible furnace is a compact furnace which makes possible to melt and hold aluminum with melting and holdingcrucible. ... In addition, because it is the crucible furnace, it is not necessary to hold the molten metal during night time, weekend, and holiday.

    We have developed the continuous aluminum melting and holding crucible furnace which is compact and it has made a continuous melting possible with a graphite crucible. It combines the features of a tower type melting furnace and stationary crucible type holding furnace. It has energy saving, high melt yield, and high quality aluminum aspect and made it possible to adjust temperature easily and eliminate periodical furnace repair. Because of its features for low-temperature melting and ideal temperature for casting and possible to melt different aluminum alloys by replacing crucible for preventing metal contamination, it is used by aluminum die-casters, sand mold and gravity casting users.  

    This continuous aluminum melting and holding crucible furnace is a compact furnace which makes possible to melt and hold aluminum with melting and holding crucible. It combines the feature of a tower type melting furnace and a stationary type crucible furnace. It has three major merits, which are energy saving, higher melt yield, and higher quality molten metal, required for this type of furnace. Time of starting up the furnace can be shortened by the light weight and higher thermal insulating furnace lining. In addition, because it is the crucible furnace, it is not necessary to hold the molten metal during night time, weekend, and holiday. As it is not necessary to operate the burner continuously, the huge amount of the energy and CO2 can be reduced during non operating period. Removing the oxide required for the conventional brick lining furnace and the periodic lining repair are not required. This crucible furnace requires only normal maintenance. By replacing the crucible, furnace returned to the brand new condition and it can be used for the high pressure die casting, gravity die casting, and sand mold casting. By replacing with a new crucible, melting of various alloys is possible and the aluminum alloys cannot be contaminated. 1.2 Structure of the furnace and the melting and holding process of the molten aluminum As shown in the Fig.1, this furnace consists of the main body, preheating tower (sliding type), combustion safety equipment, automatic thermal temperature control equipment, material charging equipment and working deck. The outside body shell has the reinforced steel plates with welding structure. High thermal insulating ceramic fiber is adopted inside the furnace in order to improve the efficiency of heat holding. We have designed a special graphite crucible for this furnace. Charged aluminum material is preheated by exhaust gas in the preheating tower, then the metal is melted in the graphite crucible. Then, molten aluminum discharged through the drain pipe that is attached to the melting crucible. Molten aluminum passes through the preheated run out tube and flows into the holding graphite crucible. The run out tube also has a role to raise the temperature that is heated by the discharged heat of the holding burner which is 800 degree Celsius. The temperature of the molten aluminum is raised rapidly to 630 degree Celsius from 600 degree Celsius. The holding molten aluminum is held in the holding crucible and is regularly held by the indirect heat. Compared with the conventional brick lining furnace that heats the molten aluminum directly, it reduces oxidation which is caused during the heating and the holding, and extremely reduces inclusion of the H2 gas and the ideal molten aluminum can be secured.
