APS steel shell furnace is safer, stronger, more efficient and more convenient to maintain.

Exclusive advantage

1. New furnace body: The steel shell furnace body adopts open structure as the German ABP.  Its basic design is an upper and lower thick-walled cylinder combined with a thick-walled seamless rectangular tube structure. The structure is reasonable and combines the advantages of steel shell and steel frame furnaces. It has higher strength, no deformation after long-term use, and more convenient maintenance. There is enough room for manoeuvre.

2. Backward tilt slag removal mechanism

The backward tilting mechanism of the furnace body realizes the backward tilting slag removal. The furnace body backward tilt mechanism can make the furnace body tilt backward, and the furnace body backward tilt angle (0-18 degrees) can be adjusted arbitrarily according to the height of the molten iron in the furnace to ensure that the molten iron and the slag removal port are at the same level, which makes the slag removal more convenient, Effortless. The slag scraper can be replaced easily and quickly. At the same time, the unique arc-shaped design of the rear platform minimizes the gap between the rear platform of the furnace body and the civil construction platform when the furnace body is tilted backward, and minimizes the debris falling from the furnace pit.

It has the following advantages: 

    1. Greatly reduces the labor intensity of the furnace operator.

    2. Improve work efficiency and make operators safer when removing slag. 3. Combined with the cyclone dust hood, it is more environmentally friendly when removing slag.

    3. Each cooling water circuit has flow temperature protection and temperature display.

3.APS new generation protective device

In addition to the anti-drop protection device, we also add a protective cover around the coil and the water-cooled cable, which can protect the coil from the damage caused by the falling or collision of metal debris, and also effectively protect the water-cooled cable from contact with metal debris and cause overheating problems. Moreover, the protective cover does not cause any trouble for maintenance, because it does not need to be dismantled during repair.

4. Each cooling water circuit has flow temperature protection and temperature display

The power cabinet adopts the GGD standard cabinet structure. The sub-cabinets are fixed on a slotted base and connected to each other through fixings to form a whole. The electrical components installed inside mainly include low-voltage vacuum circuit breakers, fast fuses, rectifiers, inverters, and various control transformers and drive components. Various display instruments and operation buttons are installed on the cabinet door. The main control board, which is the core of the control system, is also installed on the cabinet door.

Coil Technology

1. Horizontal winding

Very high electrical efficiency. The coil is wound by special horizontal winding process. The traditional water-cooled coil is canceled, and the coil is wound by an oxygen-free copper tube, without segmentation, and the coil turn gap is tight and consistent, so that the coil can obtain the maximum electrical efficiency.

2. Rodless design

Longer service life. Induction coil is design without insulating column, and it is pressed by the upper and lower steel structure, so its overall structure is much more stronger. There is no deformation problem, and the service life is longer.

3. Porcelain insulation treatment

High dielectric strength. The coil is made of first-class insulation technology. The two adjacent turns of the induction coil are strictly insulated. Insulation sheets are implanted between adjacent turns of the coil, and are pressed into a complete structure after bonding with high temperature glue. The outside of the coil is tightly wrapped with imported ceramic fiber board and high silica fiber dustproof cloth, which is completely isolated from the surrounding metal dust.

4. With furnace-leakage monitoring function, high voltage ignition and overheating protection

Low failure rate. The inner wall of the coil is evenly implanted with induction probes to monitor the leakage of the furnace and provide better protection for the permanent layer of the coil.

The coil is supplied with cooling water by multiple water channels, which are evenly distributed. The main water channel of the coil adopts dual protection of pressure and temperature to ensure that the water flow and temperature in the pipeline meet the design requirements, and have reliable protection against overheating.

5. Maintenance channel

Low maintenance cost. Scientific and reasonable coil assembly design. Provides easy access for coil maintenance and repair.

Yoke Technology

1. Wind cooling yoke

Low failure rate. The yoke is a advanced waterless yoke, which is wind cooling instead of water cooling, so it can protect it from any hidden danger of water leakage.

2. Fewer hose connections

Low maintenance cost. The yoke body requires no maintenance, and its number of hose connections is half of the conventional yoke, conducive to improve maintenance efficiency and reduce downtime.

3. Unique shock-absorbing, top-solid magnetic yoke structure.

Higher efficiency and more safer. This design eliminates the induction heating of the furnace body and the metal objects outside the furnace, which can greatly reduce the magnetic leakage, improve the melting efficiency, and saving energy. Besides, the leakage magnetic field data is maintained below an acceptable value, which also provides a safe working environment for operators.

Water Cooled Cables

The water-cooled cable adopts a hollow cable structure. Due to the structural characteristics, the water-cooled cable made of hollow conductors will not be concave or blocked at any bending angle. In addition, under the same cross-sectional area, the hollow water-cooled cable has a larger effective cross-section than the solid cable, which has a lower resistance, allowing more energy to be used for smelting.

The water-cooled cable joint adopts a detachable bolt fastening structure, which is reliable in connection and easy and quick to replace. The outer sleeve of the water-cooled cable adopts a special flame-retardant carbon-free rubber tube. This hose is not easy to burn and has good insulation strength.

Hydraulic System

The hydraulic pump station is designed for tilting full furnace load and consists of a hydraulic pump and drive motor, emergency pump, motor starting device, oil tank, oil return and oil suction filter device (and overflow prevention device).

1) One set of hydraulic pump station is used for one standby.

2) The oil tank is equipped with an oil mark and displays the liquid level.

3) The hydraulic pump station is equipped with a heat exchanger to cool the hydraulic oil and ensure the safety of the hydraulic system.

4) The tilting furnace operation table is equipped with oil pump start and stop buttons and oil pump operation indicator lights, and the furnace body (up and down) is remotely controlled; at the same time, the electrical system is equipped with an automatic pump stop function when the hydraulic pump is running but idle for 5 minutes without operation.

5) The valve body of the pump and hydraulic valve station is an imported product. The oil cylinder uses 46# hydraulic oil as the hydraulic medium.
