A pit type gas annealing furnace

Abstract

The invention discloses a well-type gas annealing furnace. The well-type gas annealing furnace comprises: a furnace body, a furnace cover, a material rack seat, a wind guide cover, a heating system and a flue gas treatment system; the furnace body is composed of a furnace shell , Furnace lining and furnace bottom, the furnace shell is made of steel plate welding machine, the furnace lining and furnace bottom are made of lightweight refractory bricks, the material frame seat is installed on the furnace bottom, and the wind guide hood is installed on the furnace Under the cover, the heating system is composed of a gas burner and an ignition control device connected to an external gas pipeline and a combustion-supporting gas pipeline. An air manifold is also arranged on the combustion-supporting gas pipeline, and the ignition control device of the gas burner includes a furnace body Several thermometers and temperature-controlled electronic ignition controllers are installed on the furnace, and the thermometers are electrically connected to the temperature-controlled electronic ignition controller; the flue gas pipeline is arranged in the middle of the furnace bottom. Through the above method, the present invention can increase the charging amount of single annealing and increase the production efficiency on the basis of ensuring uniform heating and good heat preservation effect.

Description

technical field [0001] The invention relates to the field of annealing equipment, in particular to a pit type gas annealing furnace. Background technique [0002] The well type gas furnace is mainly used for heating steel wire in a sealed state, and can also be used for disc annealing and spheroidizing. The existing direct-fired well-type gas annealing furnace is generally small in size in order to ensure the uniform temperature of the overall atmosphere in the furnace body, which is difficult to meet the needs of large-scale production, and the commonly used large-scale heating furnace is often found to have uneven ambient temperature in actual use Phenomenon, resulting in annealing can not meet the requirements, affecting the quality of subsequent processing products. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a well-type annealing furnace, which can meet the needs of large-scale annealing. [0004] In order to...
