Embodiment Construction
[0015] The heat treatment roller hearth furnace of Shanxi Taigang Stainless Steel Co., Ltd. hot rolling plant has many product varieties and structures, and the variety structure is complex, and the product variety has a large difference in process temperature. During the production process, the roll diameter bricks often fall off. The original treatment of this failure Staff are required to enter the furnace for processing. When such a failure occurs, it takes at least 72 hours just to stop the furnace and cool down, which seriously affects the contract delivery date.
[0016] After adopting the process of the present invention, by operating the working handle, one piece of 40mm steel plate and one piece of 10mm steel plate are respectively transferred from the furnace mouth and furnace tail roller table to the falling position of the roller diameter brick in the furnace. The falling roll diameter bricks are pushed onto a 10mm steel plate. The roller table of the operating h...

Abstract
The present invention relates to the field of roller hearth furnaces. A method for safely and quickly dealing with the falling failure of roller diameter bricks in a roller hearth furnace without stopping the furnace. The following steps are performed. By operating the working handle, two steel plates with different thicknesses are respectively moved from the furnace mouth and the furnace tail on the roller table to move towards each other. to the drop position of the roller diameter brick in the furnace; by operating the working handle, the two steel plates with different thicknesses continue to move towards each other, and the roller diameter brick is pushed to the thinner steel plate; by operating the working handle, the two steel plates with different thickness The steel plates move in the same direction, and the two steel plates with different thicknesses and the roll diameter bricks on the thinner steel plate are transported out of the furnace. The method of the invention does not need to stop the furnace to cool down, and does not need staff to enter the furnace for processing, which greatly reduces the fault processing time and fault processing risk.
Description
technical field [0001] The invention relates to the field of roller hearth furnaces. Background technique [0002] Roller hearth furnaces are generally used for heat treatment of medium and thick plates. Due to their unique structural form, roller diameter bricks are used for support and fire sealing on the heat treatment furnace wall and the roller diameter of the transport roller table. Due to the different heating systems for the production of medium and thick plates, the furnace needs to be heated up and down frequently, and at the same time, the loss of the transmission rollers requires regular replacement of a certain number of transmission rollers; resulting in the loosening of some roller bricks, which eventually causes the roller bricks to fall and jam. Between the two roller tables, it affects the passage of the steel plate and causes a stoppage of production. [0003] In this case, after the furnace needs to be shut down to cool down, the staff enters the furnace...
