Metal Stock S690Q steel plate

Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel S690Q steel plate. The design of the flame cutting torch provides sufficient oxygen for burning iron oxide to ensure a good cutting effect. The CNC flame cutting machine is a mechanical equipment mainly suitable for the cutting of medium and thick plates. Compared with other similar thermal cutting methods, the CNC flame cutting machine has the characteristics of high cutting quality, good cutting surface perpendicularity, and large cutting thickness.

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in S690Q steel plate etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and S690Q steel plate heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported S690Q steel plate to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

In 2020, the National Development and Reform Commission and the Ministry of Justice issued the "Opinions on Accelerating the Establishment of Green Production and Consumption Regulations and Policies", which proposed the implementation of green design, strengthening of industrial clean production, development of industrial circular economy, strengthening of industrial pollution control, promotion of clean energy development, and promotion Green development of agriculture, promotion of green development of service industry, expansion of green product consumption, promotion of green lifestyle, and many other tasks.
