Problems solved by technology
[0003] The heating furnace system equipment is mainly composed of three parts: the front of the furnace, the main body and the rear of the furnace. The main body of the heating furnace is supplied in parts of top plate, bottom plate and side wall, and the furnace body is divided into 4-6 sections, which need to be assembled on site before installation. The overall size of the components is large, and the weight of each furnace body after assembly is about 33t~40t, and it is installed under the workshop column of the main rolling span and the heating furnace span. ;The top plate, bottom plate and side wall of the furnace body are all insulated with thermal insulation cotton. The thermal insulation cotton is generally 8 layers. The thermal insulation cotton is fixed with stainless steel anchors, which requires on-site welding. The rivet welding and thermal insulation cotton laying procedures are cumbersome and the welding workload is large

Embodiment Construction
[0025] The present invention is further illustrated below by specific examples.
[0026] A modular installation method for an aluminum ingot pusher type heating furnace, comprising
[0027] Step 1. Welding of stainless steel anchors on the top plate and side wall: set up a support frame before welding the anchors, level the furnace plate, and place it horizontally so that the thermocouple tubes will not be affected; then weld the anchors with anchor guns or stainless steel electrodes nail;
[0028] Step 2. Laying of thermal insulation cotton on the roof and side wall panels: the thermal insulation cotton of the furnace body is a multi-layer structure. In order to ensure the sealing of the thermal insulation, one layer is laid horizontally and one layer vertically, and each layer is fixed with a clip. And every 2 layers form a ladder shape, the ladder length is 50mm; after the fourth layer is laid, a layer of aluminum sheet with a thickness of 10mm needs to be laid, and the jo...

Abstract
The invention relates to the field of installation of an industrial heating furnace, in particular to a modular installation method of an aluminum ingot pusher type heating furnace; the modular installation method comprises: welding of stainless steel anchor nails of a top plate and a side wall plate; laying of heat insulating cotton on the top plate and the side wall plate; heating furnace moduleassembly and combination; module turning over; and module slipping in-place. The modular installation method effectively solves a series of technical difficulties that a heating furnace assembly place is compact, the weight of the unit is heavy after the module is assembled, and cannot be hoisted by a travelling crane, working loads of the welding of the anchor nails and laying of the heat insulating cotton are large, the process is cumbersome, and the like, the heating furnace installation project can be efficiently and orderly completed, the progress and safety of the project construction can be ensured, and the modular installation method saves the construction period, improves the work efficiency, achieves good social and economic benefits, and has wide applicability.
Description
technical field [0001] The invention relates to the field of installation of industrial heating furnaces, in particular to a modular installation method of an aluminum ingot pusher type heating furnace. Background technique [0002] With the application of aluminum more and more widely, it has gradually become an important basic material in the production process; the aluminum ingot pusher heating furnace is one of the key production processes in the aluminum strip production process; the main functions of the aluminum strip pusher heating furnace It is to heat the aluminum ingot to provide raw materials for the subsequent hot rolling process, and the control of the heating temperature of the strip directly affects the quality of the subsequent hot rolled plate. [0003] The heating furnace system equipment is mainly composed of three parts: the front of the furnace, the main body and the rear of the furnace. The main body of the heating furnace is supplied in parts of top p...
