Aluminium Featured
Sustainable Aluminium
- Strong, lightweight and infinitely recyclable.
- A key element of automotive fuel efficiency, green building products and sustainable packaging.
- Poised for growth in the China and global markets.
- One of the most recycled materials on the market. More than one-third of all aluminium produced globally originates from old and new scrap.
- Recycling requires as little as 5% of the energy needed to produce primary aluminium, the International Aluminium Institute says. It also produces about 5% of the greenhouse gases.

Proven expertise
The global aluminium industry has never faced greater opportunities or greater challenges than today. Aluminium demand will continue to rise as nations demand improved energy efficiency and structural performance. At the same time, overcapacity of primary aluminium drives down metal prices and forces producers to lower costs.
We can help aluminium producers meet these challenges and maximize profitability with our comprehensive range of capital equipment, consumable products, and technical and engineering services. Over 50 Huitai engineers in more than 35 countries work directly with aluminium producers to:
- Increase metal quality and energy efficiency
- Lower cost per tonne
- Reduce environmental impact
- Consolidate supply chains
- Improve value delivery to their customers
For over 30 years, we have been helping the aluminium industry improve performance.
We welcome the opportunity to do the same with you.
Smelter(melting furnace)
Modern aluminium production originates from processes invented in the late 1890s. Once alumina is extracted from the ore bauxite, aluminium is produced through an electrolytic process in the smelter that is energy-intensive and primarily continuous.
We can help customers improve their performance in aluminium production. Within the potroom and carbon bake areas, Huitai offers consumable products, equipment and engineering expertise.
Our solutions:
- Increase metal quality
- Reduce energy costs
- Improve process efficiency
- Design custom solutions

Casthouse
Aluminium is second to steel in terms of annual usage, with the majority of production going to wrought mill products such as sheet, plate, wire, extrusions, rod, bar and forgings. In the casthouse, molten aluminium can be mixed with other metals, treated and cast into billets and ingots and other forms for downstream applications, including automotive, aerospace and more. An operation’s efficiency is measured by its cost per tonne of aluminium produced.
Our solutions impact key areas within the casthouse, from the furnace to metal transfer and metal treatment.
- Furnaces - Scrap preparation, remelt and recovery systems; metal circulation equipment; refractory lining; floor tiles; lintels and sills.
- Metal Transfer - Tapping and transfer crucibles, transfer pumps and troughs and launders.
- Metal Treatment - Fluxes and refining agents, flux-injection equipment, in-line degassing and filtration systems.
- Casting - Consumables, coatings, refractory and engineered systems for slab/rolling ingot, billet, continuous rod/sheet, remelt, sow and foundry.
Huitai products and services are designed to decrease melt loss, increase metal quality and improve a casthouse operation's efficiency.

Foundry
If the smelter produces high-quality aluminium, the foundry turns that metal into a myriad of applications through several casting processes, including high-pressure, low-pressure and sand. Foundry castings include automotive wheels, transmission housings, engine blocks, heads and pistons, as well as non-automotive applications such as motor rotors, computer chassis and machine parts.
Poor metal quality results in casting defects and increases costs for aluminium foundries and die casters who are trying to meet strict requirements and gain a profitable edge. Oxides, hydrogen and dross are introduced in all stages of the process. Scrapping inferior metal makes metal treatment practices essential. Quality aluminum castings require end-to-end process solutions.
it's foundry team focuses on improving metal quality and foundry performance with integrated systems for metal melting, transfer treatment, holding and casting.
==============================
Metal Melting - Foundry
Melting furnaces convert solid aluminium into molten metal and operate at higher energy inputs than holding furnaces. Furnace efficiency varies depending on the type of furnace, controls and scrap charge. The faster the conversion into liquid metal, the less dross or melt loss occurs. Types include reverberatory, which is most widely used, side bay/well reverberatory, dry hearth and stack melter. Melting furnaces need a different refractory lining than a holding furnace due to the higher temperatures and greater mechanical abuse they withstand. They also produce more dross and suffer from corundum and spinel reactions. They must have the melt rate required to feed die casting furnaces to maintain production.
We focuse on increasing metal quality and furnace efficiency to improve performance for die casters. Solutions for melting furnaces include circulation pumps, integrated melting systems, precast refractory shapes, flux and flux-injection equipment, furnace tools, engineering services, thermocouples, heated troughs and gaskets and seals.
- Improved energy and furnace efficiency
- Reduced melt loss and increased metal quality
- Less dross
- Higher throughput
- Lower maintenance costs
Scrap Preparation & Remelting
Recycling clean aluminium requires only about 5% of the energy required to produce the equivalent amount of primary aluminium. It also produces approximately 5% of the greenhouse gases, the International Aluminium Institute says. Remelting and recycling aluminium has increased as legislation has demanded more recycled content. Good scrap management can help increase an operation's profitability.
If quickly submerged in the aluminium bath, light-gauge scrap can melt rapidly and achieve better metal yield. If continuously melted via a submergence system, it can generate improved furnace melting efficiency and thermal performance in a closed-door operation.
Huitai's integrated melting system (IMS) provides an efficient way to prepare scrap and process machining chips to convert them back into usable metal. The jet bed dryer reduces moisture on chips, while the Huitai LOTUSS vortex continuously and quickly submerges the chips and turnings into molten metal.
Benefits include:
- High metal recovery rates
- Increased metal production
- Continuous, automated operation
- Easy installation
- Low operating cost and low maintenance
Induction Heated
Induction furnaces, whether coreless or channel, use electricity to melt metal. They are commonly used in the foundry and provide a clean, energy-efficient melting process. They have excellent recovery results when melting light-gauge material, such as chips or turnings. Increasing the amount of aluminium that can be melted is key.
Huitai focuses on improving furnace efficiency and reducing energy costs through a number of solutions, including electromagnetic circulation pumps, electromagnetic stirrers, mechanical pumps, scrap melting system, flux and flux-injection equipment for dross maintenance, furnace tools, engineering services, thermocouples, moulds, refractory lining, insulation, heated troughs and gaskets and seals.
- Energy savings through improved bath circulation, better furnace practices, proper maintenance and improved refractory and insulation packages.
- Reduced consumable costs due to longer component life and reduced maintenance requirements.
