Production processes of LR AH40 shipbuilding structural plate

Production processes of LR AH40 shipbuilding structural plate

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, LR AH40 shipbuilding structural plate steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and LR AH40 shipbuilding structural plate carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver LR AH40 shipbuilding structural plate goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while LR AH40 shipbuilding structural plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of LR AH40 shipbuilding structural plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

The Philiphine customer is our old customer, and they are engaged in offshore oilfield resources drilling projects. Thus they have regular steel demands. They ordered 1008 tons API 5L grade B ERW pipes and Q345B seamless pipes from us in April 2018. And told us that is a regular demand almost every two month. Since our first success cooperation, we have cooperated with each other regularly. And they also bring us new opportunities and signification in Philippians market.

Heat treatment specification and microstructure of LR AH40 shipbuilding structural plate, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling.
