Low-pressure casting refers to a method in which liquid metal is filled into a mold under a relatively low pressure (0.02-0.06MPa) and crystallized under pressure to form a casting Low pressure foundry. Technical features 1. The pressure and speed during pouring can be adjusted, so it can be applied to various different molds (such as metal molds, sand molds, etc.), casting various alloys and castings of various sizes; 2. The bottom injection type is adopted for filling the mold, and the metal liquid fills the mold smoothly without splashing, which can avoid the entrapment of gas and the scouring of the mold wall and core, and improve the qualified rate of castings; 3. The casting crystallizes under pressure, and the casting has a dense structure, clear contours, smooth surface, and high mechanical properties, which is particularly beneficial for the casting of large thin-walled parts; 4. The shrinkage feeder is omitted, and the metal utilization rate is increased to 90-98%; 5. The labor intensity is low, the working conditions are good, the equipment is simple, and it is easy to realize mechanization and automation. Application: mainly traditional products (cylinder heads, wheel hubs, cylinder frames, etc.)

Copper Ingot Casting 1. Equipment Introduction 2. Working Environment and Parameters 3. Brief Description of Equipment Structure 4. Equipment Installation Instructions 5. Maintenance and Safe Operation Part I Equipment Introduction The copper ingot casting line is an automated production line for continuous casting of ordinary copper ingots. Working process: The molten copper liquid comes out of the smelting furnace, is poured into the horizontal casting mold through the chute and distributor, cools and solidifies in the casting mold, and is transported to the end of the equipment and then demolded. The operator can collect the copper ingot. The copper ingot casting line has good stability, high efficiency, easy operation and simple maintenance. Part II Working Environment and Parameters (1) Ambient temperature: maximum temperature 55°C; minimum temperature: -25°C (2) Working environment: indoor. (3) Raw materials for equipment production: copper and copper alloy melt. (4) Melting copper temperature: 1100-1120℃ (5) Power supply: 380V±5%; three-phase AC: within 60Hz±1%. Part III: Brief description of equipment structure The 30kg copper ingot casting line is a fixed equipment. The molten copper from the furnace flows into the distributor through the copper chute and the casting chute, so that the molten copper is evenly injected into...
Power frequency furnace At 50/60 Hz, most inductors have a rather low power factor due to the low frequency. Values are generally 0.4 (non-ferrous metals) to 0.5 (magnetic steel heated below the Curie point). When the steel is heated to the Curie point, the impedance and voltage of the inductor are equal to those of the power supply directly to the inductor. Standard 440 volt air-cooled or water-cooled capacitors are used. For high-power industrial frequency heaters, high-voltage power supplies (3000 and 6000 volts, three-phase, 50/60 Hz) are usually used. Since the number of turns of the inductor at this voltage is very large and there are considerable insulation problems, transformers are almost always used. Power frequency furnace load sales Power factor compensation capacitors are standard models like low-voltage capacitors. The dielectric is chlorinated biphenyl or similar, and the electrodes are aluminum foil separated by resin-impregnated paper. The rating of each capacitor is standard, between 50 and 150 kvar. Recent advances in capacitors include the use of plastics instead of paper and new fluids (such as “Dielektrol”), which are safer. In smaller systems, individual capacitors are mounted in an operating cabinet or sensor cabinet. Larger systems use a separate capacitor...
Principle of Induction Melting There is no essential difference between using a pulsed magnetic field to heat a solid billet and melting metal for casting. The principle of induction heating described in this chapter still applies here. The pulsed magnetic field on the surface of the melt induces an induced electromotive force in the material, which then acts as a secondary short-circuited coil, causing current to flow in the metal and heat the metal. Except when the scrap steel is heated to the relative magnetic permeability of the Curie point, all concepts related to the skin layer depth can be used without restriction for the molten material. The advantages of induction melting are as follows 1. It can avoid the generation of undesirable metallurgical reactions such as oxidation and reduction reactions, and eliminate harmful gases and combustion products such as sulfur pollution. 2. Fast melting speed. For the same capacity, induction furnaces have a higher daily output than other types of furnaces. 3. The operating cost of the equipment is low, and its energy cost is as low as or slightly higher than that of high-efficiency fuel furnaces. 4. Improved working conditions, no large amount of heat loss and smoke...
Hongteng steel shell melting furnace have better stable and security function 2. Hongteng steel shell furnace structure is designed by computer simulation model, Furnace body tilting and hydraulic rod bearing are more reasonable. 3. Furnce energy saving 3%-5% than common furnace 4.Hongteng furnace top and bottom structure using High-temperature refractory cement integral pouring and molding, which is firm and durable. 5.The furnace mouth is made by steel, which is more durable than the traditional refractory brick and doesn’t need to replaced. 6.
