Fireking Large Stainless Steel Pizza Oven – Aldi UK

Aldi (stylised as ALDI) (German pronunciation: [ˈaldiː] ) is the common company brand name of two German multinational family-owned discount supermarket chains operating over 12,000 stores in 18 countries. The chain was founded by brothers Karl and Theo Albrecht in 1946, when they took over their mother's store in Essen. The business was split into two separate groups in 1960, that later became Aldi Nord (initially Northern West Germany), headquartered in Essen, and Aldi Süd (initially Southern West Germany), headquartered in neighbouring Mülheim.

In 1962, they introduced the name Aldi (a syllabic abbreviation for Albrecht Diskont). In Germany, Aldi Nord and Aldi Süd have been financially and legally separate since 1966, although both divisions' names may appear as if they were a single enterprise with certain store brands or when negotiating with contractor companies. The formal business name of Aldi Nord is Aldi Einkauf GmbH & Co., while the formal business name of Aldi Süd is ALDI SÜD Dienstleistungs-SE & Co. Each company is owned and operated independently, but they do have contractual business with one another.

Aldi's German operations consist of Aldi Nord's 35 individual regional companies with about 2,200 stores in western, northern, and eastern Germany, and Aldi Süd's 32 regional companies with 2,000 stores in western and southern Germany. Internationally, Aldi Nord operates in Belgium, Netherlands, France, Luxembourg, Poland, Portugal and Spain, while Aldi Süd operates in Australia, Austria, China, Hungary, Ireland, Italy, Slovenia, Switzerland, United Kingdom and the United States. In Austria and Slovenia, Aldi operates stores under the Hofer brand. Aldi Nord also owns the Trader Joe's grocery chain in the United States which operates separately from the group. Aldi Süd owns the Winn-Dixie and Harveys supermarket chains in the southern United States.

Aldi is the chief competitor of the German discount chain Lidl in several markets.

An oven is a tool that is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat.

Ovens are often used for cooking, usually baking, sometimes broiling; they can be used to heat food to a desired temperature. Ovens are also used in the manufacturing of ceramics and pottery; these ovens are sometimes referred to as kilns. Metallurgical furnaces are ovens used in the manufacturing of metals, while glass furnaces are ovens used to produce glass.

There are many methods by which different types of ovens produce heat. Some ovens heat materials using the combustion of a fuel, such as wood, coal, or natural gas, while many employ electricity. Microwave ovens heat materials by exposing them to microwave radiation, while electric ovens and electric furnaces heat materials using resistive heating. Some ovens use forced convection, the movement of gases inside the heating chamber, to enhance the heating process, or, in some cases, to change the properties of the material being heated, such as in the Bessemer method of steel production.

Pizza is an Italian dish typically consisting of a flat base of leavened wheat-based dough topped with tomato, cheese, and other ingredients, baked at a high temperature, traditionally in a wood-fired oven.

The term pizza was first recorded in the year 997 AD, in a Latin manuscript from the southern Italian town of Gaeta, in Lazio, on the border with Campania. Raffaele Esposito is often credited for creating the modern pizza in Naples. In 2009, Neapolitan pizza was registered with the European Union as a traditional speciality guaranteed (TSG) dish. In 2017, the art of making Neapolitan pizza was included on UNESCO's list of intangible cultural heritage.

Pizza and its variants are among the most popular foods in the world. Pizza is sold at a variety of restaurants, including pizzerias (pizza specialty restaurants), Mediterranean restaurants, via delivery, and as street food. In Italy, pizza served in a restaurant is presented unsliced, and is eaten with the use of a knife and fork. In casual settings, however, it is typically cut into slices to be eaten while held in the hand. Pizza is also sold in grocery stores in a variety of forms, including frozen or as kits for self-assembly. Store-bought pizzas are then cooked using a home oven.

In 2017, the world pizza market was US$128 billion, and in the US it was $44 billion spread over 76,000 pizzerias. Overall, 13% of the US population aged two years and over consumed pizza on any given day.

Stainless may refer to:

• Cleanliness, or the quality of being clean
• Stainless steel, a corrosion-resistant metal alloy
• Stainless Games, a British video game developer
• Stainless Broadcasting Company, a TV broadcaster based in Michigan, US
• Stainless Banner, the second national flag of the Confederate States of America

Steel is an alloy of iron and carbon with improved strength and fracture resistance compared to other forms of iron. Because of its high tensile strength and low cost, steel is one of the most commonly manufactured materials in the world. Steel is used in buildings, as concrete reinforcing rods, in bridges, infrastructure, tools, ships, trains, cars, bicycles, machines, electrical appliances, furniture, and weapons.

Iron is always the main element in steel, but many other elements may be present or added. Stainless steels, which are resistant to corrosion and oxidation, typically need an additional 11% chromium.

Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other elements, and inclusions within the iron act as hardening agents that prevent the movement of dislocations.

The carbon in typical steel alloys may contribute up to 2.14% of its weight. Varying the amount of carbon and many other alloying elements, as well as controlling their chemical and physical makeup in the final steel (either as solute elements, or as precipitated phases), impedes the movement of the dislocations that make pure iron ductile, and thus controls and enhances its qualities. These qualities include the hardness, quenching behaviour, need for annealing, tempering behaviour, yield strength, and tensile strength of the resulting steel. The increase in steel's strength compared to pure iron is possible only by reducing iron's ductility.

Steel was produced in bloomery furnaces for thousands of years, but its large-scale, industrial use began only after more efficient production methods were devised in the 17th century, with the introduction of the blast furnace and production of crucible steel. This was followed by the Bessemer process in England in the mid-19th century, and then by the open-hearth furnace. With the invention of the Bessemer process, a new era of mass-produced steel began. Mild steel replaced wrought iron. The German states were the major steel producers in Europe in the 19th century. American steel production was centred in Pittsburgh, Bethlehem, Pennsylvania, and Cleveland until the late 20th century. Currently, world steel production is centered in China, which produced 54% of the world's steel in 2023.

Further refinements in the process, such as basic oxygen steelmaking (BOS), largely replaced earlier methods by further lowering the cost of production and increasing the quality of the final product. Today more than 1.6 billion tons of steel is produced annually. Modern steel is generally identified by various grades defined by assorted standards organizations. The modern steel industry is one of the largest manufacturing industries in the world, but also one of the most energy and greenhouse gas emission intense industries, contributing 8% of global emissions. However, steel is also very reusable: it is one of the world's most-recycled materials, with a recycling rate of over 60% globally.
