Abstract

The invention relates to a super long muffle tank of a horizontal steel strip annealing furnace. The super long muffle tank includes a tank body, and the structural features lie in that: the tank bodyis a super-long structure formed by connection of several sections of shells, and the joints of adjacent shells are equipped with carrier rollers, lower reinforcing mechanisms and upper reinforcing mechanisms. Two adjacent shells are connected by a lower reinforcing structure and an upper reinforcing structure into a whole structure. The lower reinforcing structure includes a reinforcing body disposed at the shell bottom surface, and the lower reinforcing body is equipped with several lower reinforcing ribs, the upper reinforcing mechanism includes an upper reinforcing body disposed at the shell upper surface, and the upper reinforcing body is equipped with several upper reinforcing ribs, thus forming an overall reinforced connection structure. The carrier rollers are connected to the lower reinforcing body through a carrier roller reinforcing edge so as to form an annealing furnace steel strip support structure. The several sections of shells are connected by the overall reinforced connection structure into a super long muffle tank of the horizontal steel strip annealing furnace. The super long muffle tank of the horizontal steel strip annealing furnace provided by the inventioncan solve the problems of short length, narrow application range, easy deformation and the like in existing muffle tanks, and has the outstanding substantial characteristics of super-long length, widerange of application, deformation prevention and the like and significant technological progress.

Description

technical field [0001] The invention relates to a muffle tank, in particular to an ultra-long muffle tank for a horizontal steel belt annealing furnace, which is suitable for an ultra-long horizontal steel belt annealing furnace. It belongs to the technical field of metal heat treatment equipment. Background technique [0002] In the prior art, the length of the horizontal steel belt annealing furnace is generally about 12 meters due to the influence of the deformation of the muffle tank under high temperature conditions. If it exceeds this length, it will easily cause deformation or cracking of the tank body, and the other On the one hand, the tensile strength of the stainless steel strip hanging in the temperature (1000-2000°C) furnace decreases slightly, resulting in an increase in the amount of sagging, which affects the normal progress of bright annealing of the stainless steel strip. In addition, the process requirements of steel strip annealing, some steel strip anne...
