Induction melting furnace debugging operation method
Before the induction melting furnace is installed, it is necessary to check the components of all the complete sets of equipment, whether the main components of the furnace are properly installed and check their condition. Some parts and defects caused by improper storage should be repaired, so that all equipment, components, and corresponding materials and parts are intact, so as to ensure the smooth installation and commissioning work.
In addition, inspection and acceptance of various civil facilities related to furnace equipment, such as checking the main layout
Is the size correct; check the basics, trenches and embedded parts required for the installation of various electrical equipment and main busbars.
Requirements, whether the furnace foundation, platform elevation, vertical axis and horizontal axis deviation, anchor screw position, etc. are within the specified size range
Within; check whether the construction quality of the foundation and platform meets the requirements. Only after the above preparations are completed can the
Installation and commissioning of the furnace.
Installation and commissioning of furnaces and electrical equipment
Installation and commissioning of induction melting furnace water cooling system
The water cooling system is an important part of the whole furnace installation, and its installation and commissioning are correct.
The normal operation of the furnace in the future. Therefore, before installation and commissioning, first check whether the various pipes, hose resistance and corresponding joint dimensions in the system meet the design requirements. It is best to use seamless steel pipes for the inlet pipe, such as the use of ordinary welded steel pipes.
The inner wall of the tube should be pickled before assembly to remove rust and oil. The part of the pipe that does not need to be disassembled can be welded.
Connection requires tight welds and no leakage during pressure test. The joint of the detachable part of the pipeline shall be constructed to prevent
Water leaks and easy maintenance. ,
After the water cooling system is installed, the water pressure resistance test is required. The method is that the water pressure reaches the highest value of T, and the well protection
For ten minutes, all welds and joints are leak-free. Then pass the test of water and drainage, observe the induction
Whether the flow rate of each cooling water channel such as a water-cooled cable is the same, and appropriate adjustment is made to meet the requirements. The backup water source and its switching system should be completed before the first test. ‘
Installation and commissioning of induction melting furnace hydraulic system
The hydraulic drive has the advantages of small size, light weight and convenient control, and most of the squat and grooved induction
The electric furnaces all use a hydraulic tilting system. The design of the pumping station should be considered reliable and easy to maintain. There are multiple melting sections of induction melting furnaces. The hydraulic systems of each furnace should be able to borrow from each other to reduce the time required to stop production due to maintenance of the hydraulic system.
The oil pumping station is generally installed on a base with a certain height to facilitate oil discharge from the fuel tank during maintenance, and at the same time, it is advantageous for safe production. Even if a serious leak accident occurs, the fuel tank can be protected from the molten iron. When placing the oil pipeline, it is also necessary to proceed from the worst conditions: avoid the high temperature and iron phase at any time to prevent the accident from expanding.
Eliminating oil spills in hydraulic systems is a difficult task, starting with improving the quality of the installation. Do not
The joints of the oil pipelines to be disassembled are preferably connected by welding. The weld should be dense and free from leakage. After welding
Clean the inner wall without leaving slag and scale. Threaded oil pipeline joints should be considered for structural seals
Leak proof. When installing, take appropriate auxiliary measures, such as adding anti-leakage paint, etc., to reduce the possibility of oil leakage during operation.
After the hydraulic system is installed, the pressure test of the entire system should be carried out. The method is to pass the oil with 1.5 times working pressure for 15 minutes, carefully check the joints of each joint, weld and each component. If there is leakage, measures should be taken to eliminate one by one.
After the furnace body, water cooling system and hydraulic system are installed, the furnace body tilt test shall be carried out to check the installation quality of the furnace.
The overall inspection, such as whether the hydraulic control system is flexible and reliable, whether the actions are correct; whether the furnace body and the furnace cover are operating normally; when the furnace body is tilted to 95 degrees, the limit position switch is insured and adjusts the hydraulic pressure. The pressure and flow of the system keep it in good working order. At the same time of tilting the furnace, check the installation quality of the joint of the water cooling system, no water leakage and obstruct the tilting of the furnace body; check the hose of the hydraulic and water cooling system, observe whether the length is appropriate when the furnace body is tilted, and make appropriate if necessary Adjustment; check whether the drainage system can work normally when the furnace body is tilted. If any deficiencies are found, corresponding measures should be taken.
Before the furnace is put into operation, it must be confirmed that all signal systems are intact, the furnace limit switch is reliable when the furnace body is tilted to the maximum position, and the power supply, measuring instrument and control protection system are in a normal state, and then the furnace is knotted and Run test of the sintering furnace lining.
