Embodiment Construction

[0009] reference figure 1 As shown, a pit-type oxidation annealing furnace includes a furnace body 1. The furnace body 1 is composed of a baking zone 2 and a drying zone 3. The conveyor chain 4 passes through the furnace body 1 and enters the baking zone 2 and the drying zone. 3. Furnace entrance 5, heating wire 6, conveyor chain 4, sprocket 7 and drying oven connecting plate 8 constitute a drying zone; baking oven connecting plate 9, baking heating resistance rod 10, conveyor chain drive drum 11 and furnace body outlet The material opening 12 constitutes a baking zone; the baking zone 2 and the drying zone 3 are seamlessly connected through the baking oven connecting plate 9 and the drying oven connecting plate 8. The heating electric heating wire 6 and heating resistance rod 10 are both U-shaped design, the conveying chain 4 passes through the middle of the U, the heating electric heating wire 6 is close to the furnace wall in the drying zone 3, and the U-shaped upper and low...

Abstract

A shaft oxidation annealing furnace comprises a furnace body, the furnace body is composed of a baking area and a drying area, a conveying chain traverses through the furnace body and enters the drying area and the drying area, and a furnace body inlet, an electric heating wire, the conveying chain, a sprocket wheel and a drying furnace connecting plate form the drying area; a baking furnace connecting plate, a baking heating resistance rod, a conveying chain transmission roller and a furnace body discharge opening form the baking area; and the baking area is seamlessly abutted to the drying area through the baking furnace connecting plate and the drying furnace connecting plate. The baking area and the drying area are adopted to substitute heat insulation materials of fireproof bricks or common fibers of old products, so the heat loss is greatly reduced; and a furnace door outlet is sealed and locked, and a direct current blower is arranged in a hearth to realize uniform involution of heat in the furnace, so oxidation-free generation of workpieces of in the processing process is maintained to ensure the heat treatment quality.

Description

Technical field [0001] The invention relates to the technical field of furnaces for heat treatment, in particular to a well-type oxidation annealing furnace. technical background [0002] For the annealing heat treatment of metal materials, such as the annealing heat treatment of copper, stainless steel, small alloy materials, etc., the prior art mostly uses ordinary bell-type furnaces or pit-type oxidation annealing furnaces, which have poor furnace temperature uniformity and cannot guarantee the product during processing. Of non-oxidizing. Summary of the invention [0003] In view of the above-mentioned deficiencies in the aging heat treatment of metal materials, the purpose of the present invention is to provide a pit-type oxidation annealing furnace, which adopts a baking zone and a drying zone to greatly improve the energy-saving performance and the uniformity of the furnace temperature. [0004] The technical scheme of the present invention is realized in the following way: a...
