Fault Detection Editor 1. Temperature Loss in Casting Machine Fault Detection. In order to improve the heat preservation effect of the pouring machine, it is a pity that the lining of the furnace is only thickened. Firstly, the structure design of the casting machine is optimized, and the cover is divided into semi-fixed cover and movable cover, so as to minimize the area of movable cover and reduce the heat loss of movable cover. Because the semi-fixed cover does not need to be opened at ordinary times, it needs to be opened only when it is repaired. It can be made thicker and has better insulation effect. Secondly, the lining of pouring machine is divided into two layers, the inner layer is refractory layer, the outer layer is insulation layer, although the insulation layer is not thick, but the insulation effect is very good. Generally, the pouring machine with this structure can control the temperature loss within 2 degrees centigrade per minute. 2. The problem of drip leakage in gating machine fault detection. In fact, it is very simple to solve the problem that the bottom pouring machine often drips. Besides the plug of the pouring machine, it also rotates and tightens, which can greatly reduce the phenomenon of drip leakage of the pouring machine. Operational procedures 1. Check whether the equipment of pouring machine, electrical instruments, air passage, valves, etc. are normal, and whether the commonly used tools such as pry bars, hammers, etc. are ready. Discharge the water in the compressed air chamber. 2. When the core is laid, the hand is not allowed to close before leaving, in order to prevent crushing injury. When two people operate, they must concentrate on each other, cooperate with each other and take care of each other. Castings should be laid neatly and smoothly. The stacking height should be moderate and the pedestrian passage should be kept. 3. In case of core head, core plate is damaged or die closure is not strict, no pouring is allowed. When closing the mould, no one should stand in front of the die casting machine to avoid burning. In case of serious fire and other emergencies, the air should be deflated immediately and the power supply should be cut off. The metal liquid flowing out of the fire should be handled in time. 4. Hoisting work should comply with the safety operation rules of the hooker. Before use, the wire rope should be inspected for damage, and the hook should be hanging firmly before lifting. 5. Funnel, fast thermometer, thermocouple paint etc. should be dried before they can be used. 6. After completion, the valves should be closed, the power supply of the equipment should be cut off, and the work site should be cleaned up.

In precious metal production and processing industry, continuous casting machine is often used for casting plate, rod, pipe and other products. The continuous casting machine is integrated with melting and casting. The design of mechanization and automation makes the whole machine highly efficient, flexible and convenient to operate. It is welcomed by gold and silver jewelry manufacturers. No matter what kind of mechanical equipment, it has a service life. As an important jewelry processing and production equipment, continuous casting machine must pay attention to the maintenance and maintenance of equipment in order to prolong its service life. There are 10 maintenance measures for continuous casting machine. Let's take a look at them separately. Frequently check whether the thermocouple has a circuit break or a short circuit. 2. The observation window is often cleaned and wiped clean with cloth and paper. 3. The heating ring should be blown clean by a common air gun to ensure that the ring is 2-3 mm away from the front of the ring and that no foreign body exists. 4. Check whether the conventional pressure is up to and ensure timely replacement. 5. The flow rate of cooling water should be checked regularly and the filters at the connection of pumps should be cleaned once a month. 6. Power supply check: input 380V/three-phase AC+5%. 7. Power outage treatment: In the casting process, if there is a power outage, the standby intake valve should be opened immediately, and the main intake valve should be closed at the same time. 8. Power cut treatment: In the casting process, if water cut-off occurs, the power supply should be switched off immediately and the graphite crucible should be removed immediately in order to prevent high temperature damage to the heating sink. 9. If the rod can not be drawn after the start of the casting process, please gently clamp the rod down with a glue plier to help the discharging. 10. In the process of opening and heating, if the gas stops, the heating should be stopped immediately, and the feeding rod should be clamped to prevent the cracking of the gold rod and the leakage of the gold water. If the ten measures mentioned above can be achieved, the service life of continuous casting machine should be increased by at least 60%, and the service life of continuous casting machine will be increased, which will greatly save production costs and bring more profits to enterprises.
