WIRE ROD INTRODUCTION
Wire rod: MRS mainly export steel wire rod to international market such as South East Asia, India, Europe. Beside that, we also import steel wire rod from China and other markets.
The common standards are being used such as AISI, DIN. Beside that, according to the customer’s request, we can advise and meet the best.
Manufacturing process: To improve the surface quality of wire rods, billets are descaled by shot blasting, and inspected for surface flaws by magnetic particle tester. Ginding machines are used to remove any surface flaws. In addition, continuos ultrasonic testing is conducted to guarantee the prime quality
Reheating furnace is carefully examined, to produce prime materials in customers’ desired properties. To prevent decarburization, billets are preheated at a low temperature, followed by a full heating process, to suit a right temperature for billets’ rolling procedure. The rolling speed and fuel-to-air ratio in the reheating furnaces are fully controlled. The rolling procedure must be carefully controlled, to adjust temperature, pressure and deformation rate to form customers’ desired characteristics.
Moreover, surface roughness, sizes, and deviations are subject to adjustment to prevent any flaws.
Precise control of temperature, air volume, speed, opening and closing of slow-cooling sections are all variables that affect physical properties. Uniform fastcooling
methods are used for high carbon steel wires, and slow-cooling method is applied for alloy and lowcarbon steel.
