Continuous multi-chamber heat treatment furnace and treatment process thereof

Abstract

The heat treatment furnace comprises a heating furnace assembly composed of a plurality of heating furnace units arranged in parallel, the feeding end of the heating furnace assembly is connected with an inlet exhaust bin, and the inlet exhaust bin is connected with an inlet conveyor; the discharging end of the heating furnace assembly is sequentially connected with an air cooling unit and an outlet exhaust bin, the outlet exhaust bin is connected with an outlet conveyor, the inlet exhaust bin and the outlet exhaust bin are respectively connected with a vacuum pump through pipelines, the heating furnace assembly is connected with the vacuum pump assembly, and the multi-chamber heat treatment furnace further comprises a control system. The invention further discloses a treatment process of the heat treatment furnace. According to the scheme, the heating furnace does not need to be repeatedly cooled and heated, the energy consumption is greatly reduced, the blank heating speed is higher, and the efficiency is higher; in addition, cold air blows small batches of blanks from top to bottom, and the cooling speed is consistent; according to the invention, an automatic control technology is used, and a conveyor and a transfer mechanism are matched to realize continuous heat treatment and non-stop work.

Description

technical field [0001] The invention belongs to the technical field of heat treatment furnaces, in particular to a multi-chamber heat treatment furnace and a treatment process thereof. Background technique [0002] Existing heat treatment equipment such as figure 1 As shown, it is composed of furnace body, furnace door, return air duct, fan, air cooler, vacuum pump, control cabinet and other main parts. The process of billet heat treatment is as follows: 1. The billet (about 200Kg) is placed in the furnace body, and the furnace door is closed; 2. The air in the furnace body is evacuated by a vacuum pump to a vacuum, and then an inert protective gas is injected. The purpose is to prevent the billet from contacting with oxygen or other gases that are prone to chemical reaction of the billet during the heating process; 3. After heating to the set time, the billet is cooled by air. The fan pressurizes the hot air drawn from the return air pipe, cools it through the air cooler,...
