Furnace body and installation process of a low-temperature annealing well-type resistance furnace

Abstract

The invention discloses a furnace body of a low-temperature annealing pit-type resistance furnace and an installation technology thereof. The furnace body comprises a furnace shell and a furnace liner, wherein the furnace shell is a cylindrical pit-type structure, the furnace liner is connected to the furnace shell, reinforcing shape steels are supported in the furnace shell and connected into a grid shape, the furnace linear is a structure of fiber folding blocks, a layer of standard cotton is bonded to the surface of the furnace liner and each furnace liner block is fixedly connected in a grid-shaped frame through an anchor. The furnace body of the low-temperature annealing pit-type resistance furnace has the advantages that the folding fiber block structure of the furnace liner is adopted and the asbestos board structure on the furnace liner is replaced by the standard cotton structure, so that the thermal insulation property of the furnace liner is improved and thermal radiation is reduced; the mounting structure is simple and the process is easy to implement.

Description

technical field [0001] The invention relates to the technical field of resistance furnace manufacturing, in particular to a furnace body of a low-temperature annealing well-type resistance furnace and an installation process thereof. Background technique [0002] The well-type resistance furnace is used for uniform heat treatment of general metal parts at low temperature. It is a conventional annealing treatment equipment with good annealing effect for aluminum alloy cables and relatively energy-saving. [0003] At present, the structure of the existing well-type resistance furnace is the same as that of the general well-type furnace. It is composed of a furnace body, a furnace cover, a heating element, a charging basket, a hanger and a temperature control system. The outer shell of the furnace body is welded into a drum shape with steel. , 0.6g / cm3 ultra-light energy-saving refractory bricks are used to build a shaft-type furnace, and the load-bearing parts and parts prone ...

[0003] At present, the structure of the existing well-type resistance furnace is the same as that of the general well-type furnace. It is composed of a furnace body, a furnace cover, a heating element, a charging basket, a hanger and a temperature control system. The outer shell of the furnace body is welded into a drum shape with steel. , 0.6g / cm3 ultra-light energy-saving refractory bricks are used to build a shaft-type furnace, and the load-bearing parts and parts prone to collision are built with heavy refractory bricks, and an appropriate amount of water glass is mixed into the mud during the masonry to improve the structural strength of the furnace lining. , the insulation layer adopts the composite structure of aluminum silicate refractory well-type resistance furnace fiber, asbestos board, and diatomite insulation brick to improve the insulation performance of the furnace body and reduce the temperature rise of the furnace wall, while only using the composite structure of asbestos board and diatomite insulation brick It is known that the insulation performance of the furnace lining is not very good, and there is still a certain degree of inhomogeneity
