Energy-saving type aluminum concentrated dissolving crucible furnace for pressure casting

Abstract

The invention discloses an energy-saving type aluminum concentrated dissolving crucible furnace for pressure casting. The energy-saving type aluminum concentrated dissolving crucible furnace comprisesa rotary chassis and a plurality of boiler devices arranged on the top of the rotary chassis, each boiler device comprises a heat preservation boiler body and a heat exchanger arranged at the top ofthe heat preservation boiler body, each heat preservation boiler body comprises a boiler body shell, a calcium silicate board, a nanometer board, mullite bricks and a pouring inner layer which are sequentially arranged from outside to inside, and the outer wall of each heat preservation boiler body is provided with a nozzle and an air blower. The rotary chassis is controlled to work to drive the different boiler devices to feed materials in turns, the production technology can have the good consistency, the production efficiency is greatly improved, and the automatic production requirement ismet; a thread fire guide groove is formed in the inner wall of the pouring inner layer, flames can burn layer by layer upwards, the staying time of the flames in hearths is prolonged, and the longer the staying time in the hearths is, the longer the heating time is; and waste gas water heat utilization can be achieved, and the energy saving aim is achieved.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to an energy-saving aluminum centralized melting crucible furnace for die-casting. Background technique [0002] Crucible furnace is the simplest melting equipment, mainly used for melting non-ferrous metals with low melting point, such as copper, aluminum and their alloys. In this kind of melting furnace, the alloy is melted in the crucible, and the heat is transferred to the charge through the crucible. The combustion products of the charge are not in direct contact, so the chemical composition of the alloy is hardly affected by the furnace gas, and the temperature of the alloy liquid is relatively uniform. advantage. When smelting, metal is placed in a container called a crucible. The crucible is placed in the furnace and heated with diesel, heavy oil, gas or coke. According to different requirements, the crucible can be made of different materials such as graphite, r...

AI Technical Summary

Problems solved by technology

At present, the aluminum centralized melting crucible furnaces for die-casting on the market are basically single furnaces. In this way, when the temperature in the furnace body is too low or the material is insufficient, it needs to be shut down and waited, which makes the process inconsistent and leads to low production efficiency; When some crucible furnaces are in use, the hydrogen ions in the crucible furnace cannot be removed in time, so that the hydrogen ion content in the crucible furnace is relatively high, resulting in low quality of dissolved aluminum; the high-temperature waste gas produced by the existing crucible furnace is directly discharged to Air will lose more heat, which is not energy-saving and environmentally friendly
