Steel wire rod application in refrigerators

Mild steel wire rods are made through hot rolling. They are formed by passing molten steel through rollers to achieve the desired diameter and shape. These rods are characterised by their flexibility, ductility, and relatively low carbon content compared to other types of steel.

The mild steel wire rod coils of IS 7887:1992 specifications, including SAE1008, SAE1018, SAE1006, and SAE1010 grades, serve diverse applications. SAE1008 offers moderate strength and formability and is suitable for automotive parts and construction materials, and SAE1018 provides higher strength and machinability, which is ideal for precision machining applications like shafts and bolts. SAE1006, with its lower carbon content, is preferred for deep drawing in automotive and household appliances. SAE1010, akin to SAE1008, finds use across construction, automotive, and engineering sectors where moderate strength and weldability are essential.

Applications of steel wire rods in refrigerators
 

• Shelves and baskets: steel wire rods are often used to construct shelves and baskets inside the refrigerator. These shelves provide support for storing food items and containers.
• Door shelves: many refrigerators feature door shelves for storing smaller items like condiments, sauces, and beverages. Steel wire rods are used to create the framework for these shelves.
• Drawer slides: refrigerators often have drawers for storing fruits, vegetables, and other perishable items. Steel wire rods may be used to create the slides that allow these drawers to open and close smoothly.

• Freezer baskets: in freezer compartments, steel wire rods are commonly used to make baskets for organising frozen foods.
• Evaporator trays: steel wire rods can be used to construct essential refrigerator cooling system components.

Advantages of using steel wire rods
 

• Strength and durability: steel wire rods can withstand the weight of refrigerator components, such as shelves and trays, without bending or deforming easily. This durability ensures the refrigerator maintains its structural integrity over time, even when subjected to frequent door opening and closing.
• Flexibility: steel wire rods can be easily bent and formed into different shapes and configurations, allowing manufacturers to customise refrigerator components according to specific design requirements. For instance, they can be used to create adjustable shelves or door racks that can accommodate items of various sizes.
• Corrosion resistance: many steel wire rods are coated or treated to enhance their corrosion resistance. This is particularly important in refrigerators, where exposure to moisture and condensation is expected.

• Hygiene and cleanliness: steel wire rods are non-porous and easy to clean, making them suitable for use in environments where cleanliness is essential.
• Temperature resistance: steel wire rods can withstand a wide range of temperatures, from freezing temperatures inside the freezer compartment to ambient temperatures in the kitchen. This temperature resistance ensures refrigerator components remain stable and functional.
   

The slender profile of steel wire rods enables efficient use of space within appliances. They can create strong yet compact internal structures, maximising space for essential components and functionalities. Their availability in various sizes and configurations allows for efficient assembly.
