Advanced Rotary Kiln Technology for Superior Industrial Heating

Product Description

Product Description

Electromagnetic heating is a non-contact heating method that uses a high-frequency electromagnetic field to generate eddy currents on a conductor and causes its interior to heat itself. It has high thermal efficiency (up to more than 90%), fast heating speed, and high temperature control accuracy. It is widely used in metallurgy, heat treatment, chemical industry, food and other fields. Unlike traditional resistance or fuel heating, electromagnetic heating avoids heat conduction losses by directly acting on the heated metal body.

Product composition

1. Feeding device

Adopt chute feeding, material: wear-resistant steel, and feed is directly input into the cylinder. (Can be selected according to the production process)

2. Cylinder

The material of the cylinder (can be selected according to the heating temperature and process) is rolled in a single cylinder in the factory, and then connected to each other, corrected, and welded to form an integrated cylinder.

Cylinder speed:0.5~5 revolutions/minute, variable frequency speed regulation.

Electromagnetic induction heating is used to heat the cylinder, and the cylinder changes from radiation passive heat absorption of traditional electric heating to active self-heating.

A certain number of copying plates are arranged inside the cylinder.

3. Electromagnetic heating device

(1)Working temperature:80-1150℃, refer to calculation and test results for the final working temperature.

(2)Heating temperature zone: The heating section of the furnace body can be divided into multiple independent temperature control zones to ensure a better step-by-step preheating effect of materials.

4. Rotating device

The rotation of the cylinder adopts gear transmission and consists of a frequency conversion motor, a speed reducer, a pinion gear, a gear cover, etc. The driving device uses frequency conversion speed regulation, the pinion gear is forged from high-quality alloy steel 42CrMo, and the large gear is made of ZG310 -570. The output speed of the motor is adjusted through the frequency converter, and the speed can be adjusted from 0.5 to 5 revolutions per minute, thus achieving the purpose of adjusting the speed of the cylinder.

5. Blocking and supporting wheel device

The blocking and supporting wheel device consists of a supporting wheel base, supporting wheel, self-aligning roller bearing, blocking wheel, base, etc. The base is made of integrally welded steel, which has high bearing capacity and integrity. The cylinder is supported by two sets of supporting wheels, which reduces the probability of bending and deformation of the cylinder due to heat and improves the service life of the cylinder. An axial blocking wheel is also equipped at the supporting wheel group at the feeding end to prevent the cylinder from moving downward.

6. Sealing device

(1)The surface of the cylinder is wrapped with aluminum silicate cotton for insulation.

(2)Seal between the head and tail seal cover of the cylinder body and the cylinder body: Seal with stainless steel fish scales.

7.Electric control system

Control cabinets are divided into temperature control cabinets and PLC program control cabinets. Temperature control cabinets and PLC program control cabinets are installed in different locations. The system is designed with two control modes: remote and local: during debugging and maintenance, the local mode is used and the control is carried out on the local control box; when the equipment is running normally, the remote mode is used.

The PLC system has an Ethernet communication interface, and the temperature control instrument has an RS485 communication interface (MODBUSRTU protocol) to realize temperature setting and data monitoring on the upper computer.

Cylinder drive control: Frequency conversion speed regulation is used to control the cylinder speed, and the cylinder rotating speed can be adjusted arbitrarily within the range of 0.5~ 5r/min.

An emergency stop switch button is arranged on the control near the cylinder, and the operation panel adopts a touch screen panel.

Working Principle

Electromagnetic rotary kiln is mainly composed of combustion system, control system, cylinder, driving device, feeding and unloading system, etc. During rotary kiln operation, materials enter the rotary kiln from the kiln tail. The main transmission machine drives the gear device through the main reducer to transmit power and drive the rotary kiln barrel to rotate. The cylinder has a certain inclination, so the material moves in all directions as the cylinder rotates. The calcined clinker enters a grate cooler for cooling.

Product Features

1. High thermal efficiency, significant energy saving

2. Intelligent temperature control system

3. No smoke pollution, green and environmentally friendly

The thermal efficiency of electromagnetic heating is as high as 90%, which can achieve directional conduction of heat energy. Compared with traditional fuel heating, it can save energy consumption by 30%-50%, and the economic benefits are obvious.

.

Through multi-point temperature sensors combined with DSP/PLC systems, segmented temperature control, constant temperature control, and temperature tracking can be realized, which is more suitable for kiln process requirements that require different temperature zones.

There is no open fire, no combustion, and no smoke during the electromagnetic heating process, which fully meets the requirements of environmental protection policies and is especially suitable for urban industrial areas and areas with strict environmental protection supervision.

4. Fast response and flexible start and stop

5. Low maintenance costs and long service life

Electromagnetic heating can heat to the set temperature in a few seconds, adapting to intermittent or variable working conditions processes, and has stronger flexible production capabilities than traditional kilns.

Special electromagnetic heater system for rotary kiln

The system consists of solid-state devices with no mechanical transmission or heating wires, which reduces failure rates and maintenance workload, and the overall life is as long as 30,000 to 50,000 hours.

Application

Baking high-purity materials (such as lithium battery cathode materials, ceramics).

Urban environmentally friendly building materials enterprise;

Heat treatment links in the metallurgical industry that require high clean environment.

Replace small gas kilns, experimental kilns, and special material reactions.
