Gold and silver precious metal melting furnace to find Haituo mechanical and electrical equipment

Speaking of smelting furnaces, there are many on the market. The quality is different. Each has its own characteristics. We must pay attention when purchasing equipment. Which equipment quality is more reliable, and the market reputation is better? Below we Get up and get to know the relevant information about precious metal melting furnaces.
 


First, the melting furnace.

A smelting furnace is a device that melts an ingot and some scrap metal and adds necessary alloy components to smelt them into a desired alloy through slag, refining, and the like. Performance requirements, the melting furnace should try to meet the following basic requirements: the melting speed should be fast; the ratio of the surface area of ​​the molten pool to the depth of the molten pool should be as small as possible; the temperature of the metal in the molten pool should be uniform; the thermal efficiency of the furnace should be high; All processes of furnace and smelting should be operated by mechanized and automated methods as much as possible; the chemical stability of the furnace masonry and all aspects of the performance can guarantee the quality of the melt.

 


Second, the introduction of professional manufacturers.

Haituo Electromechanical Technology Co., Ltd. aims to save money by saving energy and environmentally friendly induction heating equipment for users. It focuses on R&D, production and process application of induction heating equipment. As of March 2015, Haituo Electromechanical has developed and manufactured The full-line high-frequency induction heating equipment includes: medium frequency melting furnace, super audio heating machine, ultra-high frequency heating equipment and supporting medium frequency diathermy forging furnace, numerical control quenching machine, chiller and related equipment, which are widely used in metal processing industry. For example, metal preheating, high frequency welding (brazing), diathermy forming, quenching, annealing, thermal filling and other processes, all products can be customized according to customer's process requirements.

Haitu dumping cabinet type molten gold furnace product process features:

1. The process of smelting, purifying, casting, etc. of precious metals is carried out mainly through a helium vessel.

Second, safe operation.

Before starting the furnace, check whether the electrical equipment, water cooling system, and sensor copper tubes are in good condition. Otherwise, it is forbidden to open the furnace. Furnace melt loss exceeds the regulations and should be repaired in time. It is strictly forbidden to smelt in the deep melt. Power transmission and furnace opening should be handled by a special person. It is strictly forbidden to touch the sensor and cable after power transmission. The shifter is not allowed to leave the post without permission, pay attention to the sensor and the external situation. When loading, check whether there are any inflammable and explosive materials in the charge. If it should be removed in time, it is forbidden to directly add cold and wet materials to the molten steel. After the molten liquid is filled to the upper part, it is strictly forbidden to add large blocks. Anti-caking. It is strictly forbidden to mix iron filings and iron oxides when replenishing the furnace and making the crucible, and the crucible must be dense. The pouring site and the pit in front of the furnace should be free of obstacles and no water to prevent the molten steel from falling to the ground.
Silver Gold Melting Machine's Precautions





1. Do not use the gold melting machine when the input voltage is too high. The power supply range should be 380V for three phases, and the voltage fluctuation is 380±5%.

2. The inside of the molten gold machine and the induction coil must be cooled by water, and the water source should be clean. The water temperature should not exceed 40 °C, so as to avoid blockage and scaling of the pipeline and accelerate the aging and damage of the machine.

3. Maintain a certain water flow rate. The water pressure of the cooling water source is ≥0.2MPa/≥3L/Min. Always check whether the cooling water is working normally after turning on the power.

4. Ensure that the fan path is unblocked.

5. To prevent electric shock, please make sure the chassis is grounded.

6. Do not press the heating switch when there is no metal in the crucible.

7. Pour the molten metal into the graphite tank, and press the stop heating switch to clamp the 坩埚.

8. In order to prevent the splash of metal liquid, the power should be adjusted to be small when the material is discharged for the first time. When the metal liquid fills the bottom of the cup, it will be gradually increased.

9, the molten gold machine should avoid sun exposure, rain, moisture and so on.

10. The repair of the molten gold machine should be carried out by professionals.


The above information is about the content of precious metal melting furnaces. There are many varieties of precious metal melting furnaces on the market, but not all varieties are reliable. We must pay attention to the selection when purchasing equipment.
