6kg Ingot Weight Aluminum Ingot Casting Machine with Mechanical Hammer Demolding and Water Spray Cooling Aluminum Ingot Caster

1. Product Overview

This chain-plate type aluminum ingot continuous casting machine is specifically designed for automatic distribution of molten aluminum into ingot molds, water spray cooling and solidification, and mechanical hammer demolding – achieving continuous aluminum ingot production. Equipped with 90 coated sand ductile iron molds, chain-plate circulating casting, capacity ≥3 tons/hour, single ingot weight 6kg. Typical applications include aluminum ingot continuous production lines in centralized aluminum casting workshops, meeting 24-hour continuous production requirements.

2. Industry Challenges & Root Cause Analysis

Poor casting weight consistency:Manual or semi-automatic casting distributes molten aluminum unevenly – large single ingot weight fluctuations affect subsequent remelting batching accuracy. Root cause: lack of synchronized distribution system and stable chain speed coordination.

Short mold life and frequent replacement:Ordinary cast iron molds crack easily under repeated thermal shock of high-temperature molten aluminum – high replacement costs. Root cause: improper mold material and casting process selection.

Low cooling efficiency and difficult demolding:Uneven spray cooling causes incomplete solidification – sticking or deformation during demolding. Root cause: mismatch between cooling water distribution design and demolding mechanism.

Insufficient equipment operation stability:Large transmission system impact and fast chain wear affect continuous production cycle. Root cause: substandard material and heat treatment of transmission components.

3. Solution

3.1 Chain-Plate Synchronous Transmission Casting:Pitch 165.8mm manganese plate quenched chain (built-in wear-resistant sleeve), rollers 45# steel, wear sleeves and pin shafts 40Cr, transmission gear discs 45# steel with high-frequency quenched tooth tips. Mold and distributor move synchronously – ensuring uniform molten aluminum injection into each mold – consistent single ingot weight. Motor with K-series variable frequency reducer – stepless speed regulation – smooth operation.

3.2 Coated Sand Ductile Iron Molds:Mold inner core uses coated sand casting process – single weight 28kg – 90 pieces total. Coated sand layer improves mold thermal shock resistance and demolding performance – extends mold service life (24-month warranty). Chain-plate circulating casting – molds continuously recycled with chain.

3.3 Water Spray Cooling & Mechanical Hammer Demolding:Cast iron water distributor with 8 nozzles – uniform spray cooling on mold bottom and sides – rapid ingot solidification. Mechanical demolding hammer strikes formed ingots from molds – reliable demolding without sticking. Cooling wastewater centrally collected.

3.4 Optimized Machine Structure:Frame welded from channel steel/rectangular tube – transmission consists of motor, reducer, front/rear sprockets and coupling. Equipment dimensions 7500×1250×1100mm (height adjustable) – adapting to different workshop layouts. Casting temperature 680-720℃.

3.5 International Brand Electrical Configuration:Inverter adopts Delta brand – control cabinet integrates variable frequency speed regulation and control system. Electrical components are all international brands with reliable performance. Accessories use market standard parts – easy procurement and repair.

6. FAQ

Q1: How is single ingot weight consistency ensured?

A: Chain-plate synchronous transmission – mold and distributor move synchronously – molten aluminum uniformly injected into each mold through 8 nozzles of water distributor. Motor with variable frequency reducer stepless speed regulation – stable chain speed – ensuring consistent weight of each ingot.

Q2: What is the mold service life?

A: Mold inner core uses coated sand casting process – single weight 28kg – good thermal shock resistance. Mold warranty 24 months. Coated sand layer improves demolding performance – reducing sticking and cracking.

Q3: Is the demolding method reliable?

A: Mechanical demolding hammer – ingots struck from molds after water spray cooling and solidification. Reliable demolding without sticking. Water distributor is cast iron with 8 nozzles – uniform spray cooling on molds.

Q4: Can the equipment operate continuously for 24 hours?

A: Yes. Chain-plate circulating casting method – molds continuously recycled with chain. Transmission components use manganese plate quenched chain, 45# steel gear discs, 40Cr wear sleeves and pin shafts – good wear resistance – meeting 24-hour continuous production requirements.

Q5: Is equipment maintenance convenient?
