Abstract

The invention discloses an auxiliary mounting device for furnace rollers of annealing furnaces. The auxiliary mounting device comprises a lifting rack. A connecting portion is arranged at one end of the lifting rack, a furnace roller bracket is arranged at the other end of the lifting rack, the connecting portion is a hinge hole or a hinge nail, and a roller neck compressing device and a lifting device are further arranged on the lifting rack; the roller neck compressing device comprises a threaded rod and two clamp blocks, a through hole is formed in each clamp block, and two nuts are further connected onto the threaded rod in a threaded manner. The auxiliary mounting device has the advantages that a lifting appliance is simple in structure, the furnace rollers can be precisely positioned at mounting stations, accordingly, the possibility of collision between the furnace rollers, constructors, other equipment or components and accidental slipping of the furnace rollers in lifting and conveying procedures can be effectively reduced, and the auxiliary mounting device is favorable for lowering in-position hoisting difficulty for mounting the furnace rollers, relieving the labor intensity and improving the mounting efficiency.

Description

technical field [0001] The invention relates to the field of metal heat treatment equipment, in particular to a device for assisting the installation of rollers in an annealing furnace. Background technique [0002] In the heat treatment method of metal materials, the metal heat treatment process in which the metal is slowly heated to a certain temperature, kept for a sufficient time, and then cooled at an appropriate speed is called annealing. The purpose of annealing is to make the material or workpiece soft after casting, forging, welding or cutting, improve the shape and toughness of the material or workpiece, homogenize the chemical composition of the material or workpiece, eliminate residual stress, and obtain the desired effect. Material physical properties. Annealing in the prior art has been refined to include recrystallization annealing, isothermal annealing, homogenization annealing, spheroidizing annealing, stress relief annealing, recrystallization annealing, s...
