Abstract

The invention discloses a stepping type magnesium alloy coiled strip annealing furnace. The furnace comprises a box type furnace body, wherein furnace doors are arranged on the front portion and the rear portion of the furnace body correspondingly, a furnace wall is arranged in the furnace body, the furnace wall longitudinally divides a furnace cavity into a hearth and a flue, the hearth comprisestwo or more heating areas, a corresponding circulating fan is arranged in a position, on the top face of each heating area, of the flue, a corresponding fuel gas radiant tube heating device is arranged in each of positions, on the two side faces of each heating area, of the flue, a lower opening is formed in the bottom wall of the furnace body, supporting cross beams used for supporting a magnesium alloy coiled strip in the hearth are arranged on the left side and the right side of the lower opening correspondingly, and a stepping type lifting device used for jacking up the magnesium alloy coiled strip supported on the supporting cross beams and pushing the magnesium alloy coiled strip forwards is arranged below the furnace body. According to the furnace, the stepping type lifting deviceis high in bearing load, large in lifting range, capable of being suitable for the heat treatment process of magnesium alloy coiled strips of different weights, high in working efficiency, adjustablein temperature of each heating area and high in heat treatment quality.

Description

technical field [0001] The invention relates to heat treatment equipment, in particular to a step-by-step magnesium alloy strip annealing furnace. Background technique [0002] Magnesium alloys have the characteristics of low density, high specific strength and specific stiffness, good electrical and thermal conductivity, non-magnetic, good shielding and non-toxic, and also have excellent properties such as easy recycling, renewable utilization and environmental friendliness, so magnesium alloys The material is known as "the green structural material of the 21st century", and has broad application prospects in the fields of national defense, aerospace, transportation, mechanical electronics and 3C electronic products. Due to the excellent microstructure and mechanical properties of rolled magnesium alloy sheets and strips, the production and research of magnesium alloy sheets and strips has become the main focus of the magnesium alloy industry in recent years. The main prod...
