Mold baking heating method, heating process method and heating furnace production device

Abstract

The invention provides a heating furnace production device. The heating furnace production device comprises a box and a heating device; a cavity is formed in the box; heating space is formed in the internal space of the cavity; the end surfaces of two ends of the box in the length direction respectively form a first end surface and a second end surface; the cavity penetrates through the first endsurface and the second end surface; an inlet and an outlet are respectively formed in the first end surface and the second end surface; the heating device heats the heating space; a passing route of heated objects passes through the inlet, the heating space and the outlet in sequence; and the passing route in the heating space forms arrangement positions of multiple heated objects in the passing direction. The invention further provides a mold baking heating method and a heating process method. A heat radiation baking mode is adopted to realize uniform heating of molds, so that the failure caused by nonuniform heating of the molds due to local overheating is prevented. Meanwhile, a heating furnace has a temperature control function, so that the heating temperatures of the molds are basically consistent, and the production process requirements are met.

Description

technical field [0001] The invention relates to the field of heating, in particular to a mold baking heating method, a heating process method and a heating furnace production device. Background technique [0002] In the production and manufacturing process of lead-acid batteries, battery grid casting (hereinafter referred to as grid casting), battery electrode group busbar casting welding (hereinafter referred to as battery casting welding) connection is a key process in the battery production process, which is directly related to the battery Production quality, efficiency, production cost, environmental protection and other aspects. [0003] In the process of grid casting and battery casting and welding, lead is injected into the mold in liquid form, and must be cooled and solidified in the mold before being taken out from the mold. Therefore, every time a production is completed, the mold needs to be heated and cooled. The heating method of the mold directly affects the p...

AI Technical Summary

Problems solved by technology

In the battery casting and welding, the cooling of the mold must also be considered, so the quality of the mold is relatively large, which leads to a long heating time, a lot of heat taken away by the mold during cooling, and high energy consumption.

The second way is to use medium frequency induction heating, which has complex structure, high equipment cost, and induction heating is prone to uneven heating

The third is flame heating. Flame heating will cause the local temperature of the mold to be high, which will easily lead to mold cracking

Moreover, these types are all open and series working methods, which have large heat dissipation and high energy consumption. The series heating can only heat one mold at a time, and the work efficiency is low.
