Lifting furnace door for thermal processing of steel plate and using method thereof

Abstract

The invention relates to the field of steel plate processing equipment, in particular to a lifting furnace door for thermal processing of steel plates and a method for using the same, including a furnace door frame, a lifting furnace door on the furnace door frame, a furnace inlet roller table on the front side of the furnace door frame, and a furnace door frame The upper side of the upper side of the furnace is provided with an avoidance mechanism one, and the side of the furnace door frame located in the furnace is provided with a buffer mechanism. The buffer mechanism is connected with the avoidance mechanism one. The avoidance mechanism one includes an avoidance plate. The outer side of the plate is fixed with a cross brace, and the side of the cross brace away from the avoidance plate is hinged with a top roller. The buffer mechanism includes a lifting plate that is slidably connected to the furnace door frame. The bottom of the lifting plate is connected to the top through a connecting rod. The rod and the ejector rod are slidingly connected and fixed in the sliding sleeve in the furnace, and a spring two is connected between the ejector rod and the sliding sleeve. The lifting furnace door for thermal processing of steel plates and its use method improve feeding efficiency and production efficiency, reduce labor intensity, and increase the service life of the furnace door frame.

Description

technical field [0001] The invention relates to the field of steel plate processing equipment, in particular to a lifting furnace door for thermal processing of steel plates and a method for using the same. Background technique [0002] After the steel plate is cast and formed, further heat treatment process is required to improve its various properties, so as to meet the requirements of use. In the heat treatment process equipment for the steel plate, the heat treatment combustion furnace is a very important part. After the steel plate is cast and formed, Pretreatment is required before entering the furnace. During this process, due to customer needs or other reasons, the edge of the cast steel plate will be uneven, such as curling. Therefore, it is very easy to get stuck in the lifting furnace door during the process of entering the furnace. It is very labor-intensive to level or re-pre-treat, which is time-consuming and inefficient. To solve this problem, application numb...

[0002] After the steel plate is cast and formed, further heat treatment process is required to improve its various properties, so as to meet the requirements of use. In the heat treatment process equipment for the steel plate, the heat treatment combustion furnace is a very important part. After the steel plate is cast and formed, Pretreatment is required before entering the furnace. During this process, due to customer needs or other reasons, the edge of the cast steel plate will be uneven, such as curling. Therefore, it is very easy to get stuck in the lifting furnace door during the process of entering the furnace. It is very labor-intensive to level or re-pre-treat, which is time-consuming and inefficient. To solve this problem, application number 201710114735.0 discloses a guide device that improves the efficiency of steel loading of buckle steel plates. An adjustable guide device is added between the roller table and the furnace, and the buckle steel plate is loaded into the furnace by the guiding function of the guide device, such as figure 1 In a, when the lowest side of the curling of the steel plate is lower than the horizontal center line of the guide wheel, the guide wheel will lose its function at this time, such as figure 1 In b, when the curling angle is large, even if the steel plate passes over the guide wheel, the curling will still be buckled on the furnace door frame due to the gap between the guide wheel and the furnace door frame, and the guide wheel needs to be adjusted several times The location is troublesome and time-consuming. When the steel plate enters the furnace, due to the uneven surface and the friction between the steel plate and the furnace door frame, the vibration impact of the steel plate on the furnace door frame is relatively large, and the damage to the furnace door frame is relatively large. After long-term impact, it is easy to cause The furnace door frame is deformed and the closing is not tight. In view of this, we propose a lifting furnace door for steel plate thermal processing and its use method
