1.Introduction
Induction furnace is widely applicable in steel melting, steel casting, and other metal alloy melting. It is composed of furnace body, hydraulic system, water cooling cable and furnace body changing switch, electrical panels.
We have induction melting furnace from 50kg to 70tons.
2.Working Principle
The induction furnace uses the medium frequency power source to establish the medium frequency magnetic field, which causes the internal induction eddy current to achieve the purpose of melting materials.
3.Main features:
1).Solid steel structure and durable;
2). Good magnetic isolation, safe and reliable;
3). Solid frequency conversion power supply, easy operation; Adjustable power rate, Easy operation and maintenance
4). Easy to start up with load or free of load
5).Energy saving design type.

1.Product Introduction
Furnace front manipulator is applied in the intermediate frequency induction furnace steelmaking workshop of the steel plant and is installed between the two furnace shells.
It can easily compact the large volume of steel scrap or too loose light material when feeding, which makes the volume of steel scrap shrink rapidly and the compactness increases, thus improving the energy conversion and greatly improving the smelting efficiency of induction furnace. At the same time can quickly, flexible induction furnace around the scrap and packaging block sweep into the furnace. with remote control operation to keep the operator away from the furnace opening area and reduce the hidden danger of safety.
2. Main functions
1) a large volume of scrap steel or too loose and lightweight material that can be easily compressed into the material.
2) The volume of scrap is reduced rapidly and the compactness is increased; thus, the energy conversion is improved greatly Melting efficiency.
3) can quickly and flexibly sweep the scrap and packing blocks around the induction furnace into the furnace body, and solve the manual many, low efficiency, unsafe operation problems.
4) Instead of the original manual operation, it solves the high intensity labor under the high temperature environment (about 1500�°C temperature radiation), and realizes the remote control operation, which greatly reduces the casualties of the workers.
5) Rapid pressure reduction, so that the furnace phosphorus is not easy to produce high temperature, reduce the corrosion of quartz sand, greatly lift high furnace refractory life.
3. Advantages: the equipment has high quality and high reliability, stable and continuous operation.
(1) The whole mechanism uses the hydraulic cylinder to drive the telescopic, lifting and rotating functions of the manipulator, the driving force is large and the operation is stable.
(2) The front and end lever of the inner beam is designed as a fast-mounted structure, which can be replaced quickly.
(3) The hydraulic components are concentrated in the rear of the equipment, which can keep away from the heat source and increase the reliability of the operation of the equipment.
(4) Use local and remote control (remote control) two control mode, and can switch freely. Remote control operation can be free to shut down and emergency power cut off.
(5) The equipment is small in size and takes up less space.
4.The equipment includes: manipulator body, hydraulic system, electric control system.
Product Description:
This cryogenic pulveriser uses liquid nitrogen as cooling medium. When crushed material is achieved at the brittle fractured state,it goes into mechanical pulverizing chamber and repeatedly impacts,collides,shears,mills by high speed rotation of blade and gear to reach the optimal crushing effect. The milled material has airflow grading machine to classify and collect. If the fineness of material does not meet the requirements,it will return silo to continue grinding. The liquid nitrogen mostly can be cyclic utilization.
Working principle:
Low temperature pulverizer system with liquid nitrogen as the cold source, the crushed material through
cooling embrittlement at low temperature easy to smash after entering the pulverizer cavity through the high-speed rotation of the impeller, the material and the leaf tooth plate, comprehensive effect between the material and the material are repeated impact, shear, collision, friction and so on, to reach the crushing effect. The crushed material is classified and collected by air classifier, and the material which does not reach the fineness requirement is returned to the silo to continue to smash, and most of the cold air is returned to the material bin for recycling.
HTG-250 MODEL: can grind grains, spices, plastics,PP,PE,PVC etc.
