Problems solved by technology
The temperature at the flame outlet of the burner is very high, which can melt metal, but the flame volume of the burner is relatively small, and sometimes it cannot be fully heated for a large metal raw material block, especially when the number of metal raw material blocks is relatively small. For a long time, there will be insufficient heating and insufficient melting
At this time, block metal will remain in the molten metal, which will affect the subsequent process.

Embodiment Construction
[0015] refer to figure 1 as shown, figure 1 A structural diagram of a metal melting furnace according to an embodiment of the present invention is disclosed. Such as figure 1 As shown, the metal melting furnace 100 includes a pre-melting chamber 102 and a main melting chamber 104 .
[0016] The pre-melting chamber 102 is provided with a low-power burner 121 , and the metal raw material block 201 is put into the pre-melting chamber 102 , and the low-power burner 121 melts the metal raw material block 201 into a metal processing block 202 with a smaller diameter. exist figure 1 In the illustrated embodiment, the top of the pre-melting chamber 102 is open, the diameter of the pre-melting chamber 102 gradually decreases from the top to the bottom, and the cross section is an inverted trapezoid. Metal raw material blocks 201 are put into the pre-melting chamber 102 from the top of the pre-melting chamber 102 . exist figure 1 In the illustrated embodiment, a low power burner 1...

The invention discloses a metal melting furnace. The metal melting furnace comprises a pre-melting chamber and a main melting chamber, wherein a low-power burner nozzle is arranged in the pre-melting chamber; raw metal blocks are fed into the pre-melting chamber and molten into a metal processing blocks with smaller diameters by the low-power burner nozzle; the main melting chamber and the pre-melting chamber are communicated with each other by a filtering separating plate; a filtering hole is formed in the filtering separating plate; the diameter of the filtering hole is less than that of each raw metal block and more than that of each metal processing block; a high-power burner nozzle is arranged in the main melting chamber; the metal processing blocks are molten to reach a molten liquid state in the main melting chamber by the high-power burner nozzle; and the main melting chamber is provided with an outlet. According to the metal melting furnace, the melting is carried out in two stages, firstly, the raw metal blocks are molten into the metal processing blocks with smaller diameters by the pre-melting chamber, and then the metal processing blocks are molten to reach the molten metal state by the main melting chamber; and smaller metal processing blocks can be molten thoroughly.
Description
technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a metal melting furnace. Background technique [0002] In the field of metallurgy, melting metal is a very common and important process. The molten metal can be used to cast metal parts of various shapes. The process of melting metal is usually achieved by heating a block of metal raw material to melt the metal into a liquid after reaching the melting point of the metal. [0003] Because the volume of the metal raw material is relatively large, and the melting of the metal requires a high temperature, it is generally heated by a burner. The temperature at the flame outlet of the burner is very high, which can melt metal, but the flame volume of the burner is relatively small, and sometimes it cannot be fully heated for a large metal raw material block, especially when the number of metal raw material blocks is relatively small. For a long time, there will be insufficient...
