Description

Technical Field

[0001] This utility model relates to the field of aluminum melting vertical furnace technology, specifically to an anti-smashing furnace section for aluminum melting vertical furnaces. Background Technology

[0002] Existing vertical shaft aluminum melting furnaces typically employ multi-section furnace bodies for assembly. These multiple sections increase the feeding height, ensuring sufficient preheating and melting of aluminum ingots within the furnace cavity. These furnaces are usually installed at the bottom of the furnace. Generally, the furnace shell is made of steel plate, while the interior is constructed with refractory bricks or castable anchoring refractory. A feeding inlet is located at the highest point of each furnace. Aluminum ingots are fed into the furnace through this inlet using a feeding device. In current technology, due to the large quantity and weight of the ingots, each feeding generates significant impact. This impact occurs at the feeding inlet, inside the refractory material of the furnace body. Because of the furnace structure, the aluminum ingots directly impact the refractory material. Under the combined effects of high temperature and impact, the refractory material quickly breaks down and falls off. As deterioration intensifies, large-scale refractory material loss leaves the outer steel plate of the furnace shell exposed to direct flame. The impact and oxidation reaction rapidly burn through the furnace shell, leading to flame leakage and rendering the furnace unusable. Utility Model Content
