Novel annealing furnace

Abstract

The invention relates to a novel annealing furnace. The novel annealing furnace comprises a furnace body, a heat-insulation layer, a housing, and an electromagnetic heating system. The furnace body is divided to several heating chambers by several blocks of heat-insulation warming plates, a hot air circulation blower fan is arranged at top of each heating chamber, a furnace roller and an electromagnetic heating plate are arranged at the bottom of each heating chamber, the furnace roller is arranged on the electromagnetic heating plate; an air channel is arranged below a blowing port of the hot air circulation blower fan; the blowing port is arranged on the air channel, a dust cap is arranged on the blowing port, and the electromagnetic heating system comprises multi-group magnet ring wires arranged at two sides of the housing and a controller electrically connected with the magnet ring wires. The novel annealing furnace realizes uniform heating for the metal wire, increases the heat efficiency, saves the energy, and has the advantages of environmental protection, no pollution on air, and strong practicality; rapid heating and insulation effects can be realized for the annealing furnace, the furnace body is divided into several heating chambers, the heating is rapid and uniform, the production efficiency is high, the dust cap is arranged on the blowing port, cleaning in the furnace is guaranteed, and the product quality is increased.

Description

technical field [0001] The invention relates to a novel annealing furnace. Background technique [0002] Metal wire and its products are new industrial materials and high-tech and high value-added products developed in the past 20 years. It not only has the flexibility of chemical fiber, synthetic fiber and its products, but also has the excellent thermal conductivity, electrical conductivity, corrosion resistance, high temperature resistance and other characteristics of metal itself, and is widely used in textiles, machinery manufacturing, heat treatment, aerospace, household appliances and other fields , is a necessary key material in many industrial fields and defense industry, which fully embodies the intersectionality and excellence of modern material science. Metal wire is generally made by a set of special processes such as cold drawing and heat treatment. Heat treatment is a necessary process to make the drawn hard metal wire into a soft state. Among them, the annea...
