Product Specification

※ Product use:

Gas heat treatment furnace is suitable for metallurgy, machinery, chemical equipment, large shaft, forgings, steel castings, pressure vessels, large welding parts heat treatment.

※ Product Features:

1. The combustion medium is heated by natural gas, with full combustion, no pollution, fast heating speed, the maximum use temperature can reach 650-1200℃, and the flue gas emission is in line with the "GB9078-88 industrial kiln smoke layer discharge Put standard ";

2. The furnace lining adopts alumina ceramic fiber module structure, the furnace lining has small heat storage, low heat loss and significant energy saving

3. High speed pulse burner is used for heating, and both sides are evenly distributed. Continuous proportional adjustment of combustion, the actuator to adjust the size of the air volume, through the proportional valve to adjust the size of the gas volume. Achieve air-fuel ratio combustion

The gas and air volume are provided with a lower limit, and the gas pipe of each burner is provided with a control solenoid valve. Each burner is equipped with an independent and complete combustion controller with automatic ignition, flame detection, and fire suppression

Alarm automatically cut off gas. This fully ensures the stability and safety of the combustion temperature control system.

4. Waste heat utilization: the high-temperature flue gas in the furnace is preheated to 250-300℃ through the heat exchanger of the air pipe hot air temperature, and then sent into the furnace, saving a lot of gas consumption and saving production costs;

5. The furnace door of the gas heating furnace adopts a high-aluminum all-fiber fire-resistant wire and heat-resistant steel composite frame structure, the electric hoist is lifted, and the sealing mechanism of the furnace door adopts a long and short lever spring type automatic compression CAM machine

Structure (optional electric cylinder pressing device) and soft edge sealing device. Ensure up and down frictionless, easy, safe and reliable.

6. The truck refractory masonry adopts high aluminum shaped brick structure, which has good sealing effect with the furnace body and can withstand pressure strength. The pallet iron is used for stacking workpieces. The frame of the pallet is all made of heat-resistant steel

Certificate body deformation and durability. The sealing block of the furnace body and the furnace lining is automatically pressed by the electric push rod (or cylinder), and the opening and closing of the side and seal are interlocked with the furnace car.

7. Control system: intelligent PLC control type computer automatic control

7.1. Furnace temperature control system:

Adopt advanced intelligent digital temperature control instrument. It is composed of closed-loop control with temperature measuring element and automatic burner. The temperature controller interface is connected to the upper PC through R485(RS422) bus to form intelligent heat

Treatment furnace temperature control system. The upper PC adopts industrial control computer and high resolution LCD display, and is equipped with self-developed HMI monitoring software, so that the whole system has a good use

The user interface. Using advanced fuzzy control principle, it has high precision, high flexibility, anti-interference and high reliability. The temperature control system can automatically measure the process curve of heat treatment production

Calculation, operation, display, storage, the whole process control.

7.2. Furnace pressure automatic control system:

The furnace pressure can be set and automatically adjusted, so that the furnace pressure is controlled in the best value, to ensure the stability of the furnace and make full use of the furnace gas heat

7.3. Automatic control system of pipeline parameters

The pressure of the combustion air pipeline and fuel pipeline required by the combustion system can be set and automatically adjusted, so that the combustion air and fuel are controlled in the best ratio, ensuring a high combustion efficiency and eliminating

There was black smoke.

7.4. Reliable safety protection system:

The instrument cabinet is equipped with the operating value display of temperature, furnace pressure, each burner and each pipeline parameter, abnormal situation alarm and emergency protection measures to ensure safe operation.

8. Centralized control system

High precision Siemens PLC is used as the core unit of the whole furnace temperature control system. The control of temperature, pressure and combustion air pressure in the furnace is completed by PLC. This reduces temperature control and quantity

All kinds of instruments, such as word adjustment, hand operator and digital display instrument, greatly reduce the complexity of the whole system configuration.

The upper PC adopts industrial control computer and high resolution LCD display, with self-developed HMI monitoring software, so that the whole system has a good user interface at the same time monitoring several sets

The furnace or furnace needs to be monitored by the upper computer (two or more PCS monitor one or several furnaces at the same time, and the advantage is that the failure of a PC does not affect the normal operation of the entire system).

The software can easily meet the requirements.

※ Design and Manufacture certification:

1. The indicators are designed and manufactured according to the national standards of industrial furnaces

2. Conduct the performance test of various components and issue a report (support customer on-site pre-acceptance)
