Product Description
The copper melting furnace has uniform heating temperature, less combustion damage, uniform metal composition, good casting quality, fast melting and heating, convenient furnace temperature control, high production efficiency, sensitive, convenient, continuous and smooth power regulation, uniform temperature control, less oxidation and combustion, uniform metal composition, and the shell adopts cast aluminum alloy or steel alloy or steel shell structure with small area; The furnace body is easy to turn over, and electric, manual, hydraulic and other methods can be selected according to needs; The melting solution can be emptied directly from the cold furnace, and it is convenient to change the type of melt.
The first stage is mainly arcing. After the copper melting furnace is powered on, the electrode emits hot electrons and sends out a large number of electrons from the cathode. The high-speed electrons can dissociate neutral air molecules into ions, so that the air has the ability to conduct electricity, generate an arc and release a large amount of light and heat.
The second stage is mainly the penetration of the electrode and the melting of the stainless steel under the electrode. After the arc is passed through the copper melting furnace, the stainless steel under the electrode is heated and melted.
The third stage is mainly the melting of copper blocks around the electrode and the recovery of the electrode. With the progress of melting, the liquid level rises continuously, and the electrode rises accordingly. During the recovery process, the surrounding copper blocks gradually melt. When there is only some unmelted stainless steel left on the furnace slope and bottom in the copper melting furnace, the arc is still surrounded by cold materials for most of the time, and high power should still be transmitted to the furnace.
The fourth stage is the melting of stainless steel in the low-temperature furnace area. The electric arc is the point heat source. The temperature distribution in the furnace is uneven. The stainless steel near the furnace door and on both sides of the steel outlet melts slowly. The cold materials in these places should be pushed into the molten pool in time; And the input power and voltage should be appropriately reduced.
