SPECIAL PURPOSE VEHICLES For the Primary Aluminium Smelters Efficiency Safety Ergonomics

Mobile and stationary equipment for the aluminium industry HMR Hydeq's business idea is first and foremost to design and build special vehicles for the aluminium industry with high quality that satisfies the strongest demands regarding safety, technological solutions and working conditions in the smelter. The enterprise, which in 1989 was named Hydeq, grew out of a department of Hydro Aluminium Ardal (one of Norway's largest aluminium smelters), that had been established in 1973. It is today a private company, incorporated in the HMR Group. The holding consists of nine companies, specialised...

3 SPECIAL MOBILE AND STATIONARY EQUIPMENT HMR Hydeq designs and manufactures modern special purpose vehicles and stationary equipment for primary aluminium plants. TAPPING VEHICLE ANODE COVERING VEHICLE The equipment is carefully adapted to meet the individual needs and requirements of the customers. Maintenance, service and spare parts are the natural extension of services provided by HMR. So far the company has produced more than 300 different special purpose vehicles, including: Tapping Vehicles Anode Changers Crust Breakers Cavity Cleaners Feeders Furnace Tending Vehicles, etc. Our technical...

COMPLETE CLOSED TAPPING SYSTEM Our customers benefit from several major advantages of this tapping system: ■ Excellent safety and ergonomics for the operator and the ■ No need for overhead cranes, transporters, additional floor personnel. weighing systems, tilters, etc. ■ High operating speed, flexibility and Just in Time ■ Reducing operating costs by lower oxidation and performance. lower temperature loss. ■ Automated and self-sufficient. ■ The whole process is controlled by one operator only.

TAPPING SYSTEM IN USE Many aluminium smelters have benefited from HMR’s tapping vehicles the last 40 years. In 2009 HMR Hydeq supplied the complete tapping system to the aluminium plant in Qatar. Thirteen tapping vehicles, crucible cleaner and other stationary equipment are in operation in Qatalum. The Qatalum contract is the ultimate showroom for HMR’s products in the Middle East. At the beginning of 2012 Rio Tinto Iceland (ISAL) put into operation a complete tapping system, consisting of five tapping vehicles, one crucible cleaner and auxiliary equipment. The system delivered by HMR was chosen...

Operation philosophy ■ Maximum safety and operator comfort ■ Maximum precision on tapped and recorded weight ■ Minimum temperature loss ■ Minimum metal spill and oxidation ■ Minimum tapped and delivered dross Tapping vehicle’s features ■ All functions operated from cabin. ■ Elevation and traverse system for positioning the crucible for tapping and discharging. ■ Vehicle can release and retrieve a fully loaded crucible. ■ Regulation of vacuum to minimise bath tapping. ■ Automatic stop of tapping when ordered amount is reached, or when crucible is full. ■ Registration of tapped amount from each...

This type of the vehicle is used...

Information on the amount of molten aluminium to be delivered and cells to be tapped are directly broadcasted to the driver of the tapping vehicle. No floor personnel is required. By means of the weighing, the system stops automatically when the ordered amount of metal is tapped. When launder is applied, the MTV can discharge both metal and bath to a pot during start-up procedure. No need for a tilter in the cast house as the tapping vehicle discharges the metal by itself. The hydraulic suspension system tilts the vehicle during discharging to optimize process. Dross and bath remain in the crucible...

The cab has superb driver conditions. Visibility and ergonomic standards have our highest attention. All major components are located to give easy maintenance access. CRUCIBLE MOVEMENTS The vehicle can manoeuvre the fully loaded crucible without help from any additional equipment.

10 CRUCIBLE CLEANING STATION Crucible Cleaning Station is part of HMR’s tapping system. The cleaner, like most of the machines from HMR Hydeq, is fully automatic and can be operated by the vehicle operator. At HMR’s crucible cleaning station the crucible can be cleaned while it is still hot. It reduces the total amount of crucibles needed at the smelter and extends the lifetime of the ladles. The tapping vehicle leaves the crucible on a pallet. The crucible is picked up and tilted, in order to empty metal and dross in separate skips. A full profile mill, driven by hydraulic motor, removes dross...
