Description

Technical Field

[0001] The invention relates to the technical field of furnace top pull rods, in particular to a furnace top magnetic pull rod device. Background Art

[0002] Industrial heat treatment furnaces with a span of less than 5m, such as heating furnaces, soaking furnaces, annealing furnaces, etc., account for more than 70% of existing heat treatment furnaces. Except for a small number of them that adopt flat-top structures, most of them adopt arched furnace roof structures. Traditional arched roof structures can be divided into two categories: one is a brick arch, which is built with refractory bricks and refractory mud. Due to the large number of brick joints, large heat dissipation, energy waste, and troublesome construction, as well as the poor volume stability of bricks and the fact that the quality of masonry is greatly affected by human factors, the service life is short, generally only 9 to 12 months; the other is an integral arched furnace roof made of refractory castables or plastic prefabricated or on-site, so a furnace roof tie rod device is required.

[0003] Comparative patent CN201920672463.0 is a new type of arched furnace roof structure for heating furnace in forging workshop, which has the following records inside: including an arched furnace roof, the two sides of the arched furnace roof are supported on the furnace wall, and oppositely arranged columns are distributed on both sides of the arched furnace roof along the long direction of the arched furnace roof, and a pull rod is fixedly connected between the oppositely arranged columns, and the pull rod is located above the arched furnace roof. The arched furnace roof includes a plurality of overlapping strip insulation plates, and the strip insulation plates are arranged along the long direction of the arched furnace roof; a reinforcing rod is arranged in the arched furnace roof, and the reinforcing rod is arranged along the circumference of the arched furnace roof, and the strip insulation plates are all penetrated on the reinforcing rod, and reinforcing rods are evenly distributed along the long direction of the arched furnace roof; hangers are evenly distributed on the reinforcing rods, and the two ends of the hangers are fixedly connected to the reinforcing rods and the pull rods respectively. The reinforcing rods are penetrated in the arched furnace roof, and are fixedly connected to the pull rods arranged between the columns through the hangers, so as to ensure the stability of the arched furnace roof structure and make it not easy to deform.

[0004] The existing furnace top magnetic pull rod device is difficult to quickly and stably open and close the pull rod and the frame during use, it is difficult to improve the operating efficiency, and it is not convenient to operate the position relationship between the furnace cover and the furnace body according to actual conditions.
