Composite type annealing furnace

Abstract

The invention relates to a composite annealing furnace, comprising a furnace body which is internally provided with an electric heating system. The composite annealing furnace is characterized in that the furnace body is separation type; and the furnace consists of a furnace mantle, a hearth and a hydraulic lift which is matched with the furnace mantle that is internally provided with the electric heating system and a hot air circulating system; the hearth is a structure of a double-trolley, under which a walking wheel and a brake are arranged, and the walking wheel is matched with a rail arranged on the ground; the hot air circulating system consists of a side air director and a plurality of hot circulating fans which are arranged on the top of the furnace mantle; and the lifting device consists of a lift guiding device arranged around the furnace mantle and a hydraulic lifting device which is vertically arranged. The furnace realizes uniform annealing, and improves heat efficiency and product quality, thus achieving the purposes of saving energy, reducing consumption and increasing economic benefits.

Description

technical field [0001] The invention relates to metal heat treatment equipment, in particular to a trolley-type annealing furnace used in the brass calendering process. Background technique [0002] At present, most of the copper processing enterprises at home and abroad, especially the brass and lead brass rolling processing enterprises, use ordinary far-infrared trolley-type annealing furnaces for bar annealing. The internal hot gas flow is turbulent, and the air flow velocity is uneven, resulting in a large temperature difference between the upper and lower sides during annealing, and the product quality is difficult to guarantee; the bottom cannot be completely sealed due to structural reasons, and the energy utilization efficiency is low, and the furnace wall is generally made of multi-layer refractory bricks. Heavy weight, inconvenient installation, low production efficiency, more heat dissipation, not only wasting resources, but also deteriorating the surrounding work...
