Pit-type aluminum ingot heating furnace

Abstract

The invention provides a pit-type aluminum ingot heating furnace which comprises a furnace body, a circulating fan, a heating system, a diversion system, a jack-up furnace door, a furnace door lifting and transferring mechanism and a furnace temperature detection device, wherein the jack-up furnace door is positioned at the top of the furnace body; the port of the furnace door is flush with the floor of a workshop; a sealing device is arranged between the furnace door and the port of the furnace door; the furnace door lifting and transferring mechanism controls the opening and the closing of the furnace door; the heating system is arranged at the bottom of the furnace; the diversion system is distributed in a hearth; furnace gas flows orderly in the furnace along the diversion system under the action of the circulating fan; and the furnace temperature detection device is arranged on the furnace body. The pit-type aluminum ingot heating furnace can be used for realizing different requirements of various alloys on the heating temperatures and meeting the small-lot production requirements of multi-alloy series, and has the characteristic of strong production flexibility; and meanwhile, the furnace door lifting and transferring mechanism and a circulating fan installation and overhaul mechanism have strong community, so that the input cost for the increase in quantity of pit-type heating furnaces is lowered.

Description

technical field [0001] The invention relates to a heating furnace suitable for heating aluminum slabs before hot rolling of aluminum and aluminum alloy slabs in the field of nonferrous metal processing, in particular to a pit-type heating furnace for small batch production of multi-alloy varieties of aluminum ingots. Background technique [0002] In the current aluminum processing industry, the most widely used types of aluminum ingot heating furnaces are vertical push type aluminum ingot heating furnace and trolley type aluminum ingot heating furnace. [0003] Among them, the vertical pushing aluminum ingot heating furnace is a semi-continuous or continuous heating furnace, which can realize continuous production, has the characteristics of small heat loss and high energy efficiency, and can realize independent temperature control in different heating zones, which can meet the heating requirements of different heating stages. Require. However, because it is produced contin...

Problems solved by technology

Due to the limitation of this furnace type, when the heated ingot is out of the furnace, it is necessary to use a trolley to take out the entire furnace of aluminum ingots, and then use a crane or an ingot transfer mechanism to transport the ingots that need to be hot-rolled to the hot rolling mill. Other ingots need to be reloaded into the furnace for heat preservation to wait for the demand of the hot rolling mill, because there are multiple ingots entering and exiting the furnace, resulting in additional energy waste and increased production and operation costs
