Key smelting points to ensure the successful production of ZQS700L 1.2mm coil

High toughness and low brittleness transition temperature: with the increase of the working pressure of the ZQS700L 1.2mm coil gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor aff

High toughness and low brittleness transition temperature: with the increase of the working pressure of the ZQS700L 1.2mm coil gas pipeline, the pipe diameter becomes larger, and the pipeline fracture accidents often occur. Toughness is the key factor affecting pipeline fracture. In order to ensure ZQS700L 1.2mm coil pipeline safety, toughness and strength must be improved at the same time.

Our company's ZQS700L 1.2mm coil power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the ZQS700L 1.2mm coil utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and ZQS700L 1.2mm coil steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and ZQS700L 1.2mm coil medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.

During cladding welding of hardfacing wear-resistant steel plate, ZQS700L 1.2mm coil, preheating and slow cooling should not be adopted. Sometimes, forced cooling measures are even taken to reduce the residence time of weld in the temperature range of 400-850℃ to prevent local chromium deficiency in austenite grain boundary and σ brittle phase in the plate, resulting in 475℃ brittleness, so as to ensure that the weld metal has good mechanical properties and intergranular corrosion resistance.
