Description
Technical Field
The invention relates to a device for charging a heating furnace.
Background
The entrance of the existing heating furnace is provided with a rail type structure, and a steel billet is conveyed into the furnace by a speed reducer motor driving ground roller. Because the cold steel blank generally has the conditions of blank bending and blank warping, the normal furnace entering rhythm is influenced, and great operation difficulty is brought to the furnace entering work of a furnace entering operator. Meanwhile, the cold rigid blank with the downward-bent front end also frequently drills into the lower part of the ground roller to pry up or damage the whole ground roller when entering the furnace, so that the normal use of equipment is greatly influenced, and the maintenance work is greatly increased. In addition, because the ground roller of the furnace door is close to the region of the furnace door, the bearing of the ground roller often has the condition of oil shortage and blocking.
Disclosure of Invention
In view of the above, the present invention provides a feeding device for a heating furnace, which uses a ramp instead of a roller as a furnace entrance guide and is provided with a water cooling cycle to cool and dissipate heat, thereby avoiding thermal deformation.
In order to solve the technical problems, the technical scheme of the invention is as follows: a heating furnace feeding device comprises a steel pushing device and a furnace front guide device, wherein the furnace front guide device comprises a water tank, and the top surface of the water tank is an inclined plane with a lower front part and a higher rear part; the top surface of the water tank is provided with a left baffle and a right baffle which are arranged in a splayed shape; the water tank is provided with a liquid inlet and a liquid outlet, and the liquid inlet and the liquid outlet are connected with the heat dissipation device.
As an improvement, the steel pushing device is arranged in front of the furnace front guide device and comprises a plurality of conveying rollers, and a track is arranged above the conveying rollers; the trolley is arranged on the track and can move back and forth along the track; and a push rod for pushing the steel billets is arranged on the trolley. The steel pushing device is used for driving the steel billet to enter the heating furnace.
As an improvement, the front end of the push rod is provided with a push head; the push head is connected with the push rod by a pin shaft, so that the push head can be turned over up and down; and a limiting device is arranged on the push rod behind the push head. Through the effect of stop device, the pusher head can only overturn to the fire door direction. The pusher head must be movable since the newly advanced billet has to pass under the pusher rod. In the process of pushing steel, the limiting device limits the push head to turn backwards so as to bear force.
Preferably, the trolley is provided with rollers matched with the rails, and the rollers are driven by a motor.
As an improvement, the minimum gap between the left baffle plate and the right baffle plate is consistent with the width of the billet. So that the steel billet can accurately enter the furnace mouth.
Preferably, the upper top surface of the conveying roller and the initial position of the top surface of the water tank are at the same level. The billet can be smoothly transited on the conveying roller and the furnace front guide device.
As an improvement, the inclination of the top surface of the water tank is 10-15 degrees. The purpose of setting the slope is to prevent the steel billet with the downward bent front end from being clamped between the guide device and the furnace mouth to cause the damage of the furnace body. When the front end of the steel sheet is bent downwards after a certain inclination angle is formed, the problem can not be caused. The inclination angle is not too large, otherwise the slope of the water tank is impacted.
As an improvement, the outside of the baffle is provided with a reinforcing rib, so that the strength of the baffle is improved.
As an improvement, the heat dissipation device comprises a heat dissipation water tank, a water inlet pipe connected with a water outlet of the water tank, and a water outlet pipe connected with a water inlet of the water tank and the heat dissipation water tank; the part of the water inlet pipe located in the heat dissipation water pool is provided with a nozzle.
As a modification, the jetting direction of the nozzle is upward. The upward spraying of the cooling circulating water facilitates the falling of the cooling circulating water into the heat dissipation water tank, and avoids the outward sprinkling.
The invention has the advantages that: the heating furnace feeding device with the structure utilizes the water tank with the slope surface to replace the ground roller to reverse the steel billet, and the situation that the ground roller is damaged when the irregular steel billet is clamped into the lower part of the ground roller is avoided. Meanwhile, water cooling circulation is carried out in the water tank, so that the thermal deformation of the water tank is effectively avoided, and the service life of the water tank is prolonged.
