How does the push-rod furnace work? What should I pay attention to when using it?

Push rod furnace is currently used for heating production of a more common equipment, mainly used for wear resistant steel ball, medium and small metal parts quenching, normalizing and other heat treatment, so you know the working principle of this equipment is how? The detailed working principle will be introduced in the following article. In addition, related operators in the use of the rod furnace when the need to pay attention to what matters? For example, the new furnace must be put into use according to the specified procedure, temperature rise curve oven, and the explosion protection door must not be blocked with other objects, so as not to lose the explosion protection effect. The following small make up to understand the relevant content in detail.

One, push rod furnace working principle

Pusher-rod steel ball heat treatment production line, which is mainly used for hardening and normalizing heat treatment of wear-resisting steel ball, medium and small metal parts. The heating temperature is 1100 degrees. Pusher type steel ball heat treatment production line is composed of pusher furnace body, pusher machine, track, charging frame, turning mechanism, quenching oil tank, hydraulic station and electric control system, etc.

Push-rod type steel ball heat treatment production line, almost all mechanical action is driven by hydraulic, all hydraulic oil collected to a hydraulic station centralized control of smooth action. Make the mechanical action system of production line simple and efficient. The operation process is that the basket is filled with steel balls and placed on the working platform in front of the furnace. The hydraulic cylinder opens the front and rear furnace doors, and the cylinder pusher pushes the basket placed on the roller into the pusher furnace in turn. At this time, the furnace door before and after the closing continues to heat, so as to complete the working cycle of each basket.

Fully automatic production mode not only ensures the stability of heat treatment process, but also greatly reduces the labor intensity of operators. Combined with the current automatic program control system, the new generation of energy-saving continuous heat treatment equipment has the characteristics of safety and energy saving, stable operation, simple operation and high degree of automation.

The power of electric heater should be arranged according to the process and adjusted in the debugging process. The pushing cycle is adjustable, the furnace door, push rod and discharging platform are controlled by PC, interlock. Temperature control instrument is PID regulated table, temperature can be controlled to display, and is equipped with broken couple protection, overtemperature alarm.

The furnace door mechanism is driven by hydraulic cylinder, which completes the opening and closing action of the furnace door, and the finite position switch limits the travel of the furnace door. The pusher machine is composed of pusher table, oil cylinder and hydraulic device. The cylinder pushes the basket into the furnace workbench with rollers. The track is made of heat-resistant cast steel, and is provided with a roller and a material disk to pass on the roller. This can reduce the running resistance of the plate. The basket is made of heat-resistant cast steel.

Two, the use of the push rod furnace needs to pay attention to matters

What should I pay attention to when using the pushrod furnace? The following is the detailed introduction.

1. All pushrod furnaces must have the following components and safety facilities. Automatic outlet temperature regulating device; Automatic control device for raw oil; Temperature indicator for furnace, convection, furnace tube, radiation and flue.

2. Furnace outlet population and superheated steam pressure gauge; Adjust the damper and flue damper; Emergency vent device; Explosion door; Fire extinguishing steam line of furnace and return elbow box.

3, the new furnace operation must be in accordance with the prescribed procedures, heating curve for the oven.

4, push rod furnace before ignition, should close the manhole, flue baffle to 1/3 to 1/2, set up fuel oil system circulation and raw material circulation, ready to soak the diesel ignition rod.

5, before ignition, should first use steam to remove residual gas in the furnace, will have lit the ignition rod on the top end of the gas furnace burner, wait for people to leave the bottom of the furnace, a little steam, then open the oil line. After burning the fuel oil, adjust the oil-gas ratio to the normal state.

6, in a safe place to empty more than 15 minutes, after laboratory analysis of oxygen content less than 1%, can be put into ignition.

7. When the fire is lit, the fireman should not face the gas mouth and the window to see the fire, so as to avoid hurting people by backfiring. If the flame is extinguished, the fuel valve should be closed immediately, and the furnace can be re-ignited after steam purge.

8, normal operation of the gas furnace, the furnace should often check the burning situation, found the situation immediately report to the leadership, take measures to deal with.

9. In case of fire in the furnace caused by the burning and rupture of the furnace pipe or emergency that requires people to enter the furnace, steam shall be used for fire-extinguishing and cooling treatment. It is strictly prohibited to spray water into the furnace for fire-extinguishing and cooling.

10. When entering the push-rod furnace for maintenance, the operation procedures for entering the equipment shall be handled. The explosion-proof door should not be blocked with other objects to avoid losing the explosion-proof effect.

11, point furnace temperature rise or stop furnace temperature must be in strict accordance with the prescribed speed of temperature rise.

12. In case of emergency shutdown of the furnace, it is forbidden to close the control valve with only instrument wind, and it must be carried out in strict accordance with the operation process of the gas generator furnace.

13. If the heating medium is interrupted, immediately put out the fire and let steam into the furnace.

The above is about the working principle of the push rod furnace and the introduction of the matters needing attention, you should have a general understanding of the push rod furnace, if you have other questions you can consult us.
