At present, the company has successfully developed and produced more than 10 kinds of boron-containing steel varieties such as 35MnBM, 23MnBM, quenched and tempered GL-E40 hull steel plate, 27MnTiB, 40MnB, 25CrMoTi, etc. According to the practice of Laiwu Steel's 50t electric arc furnace-50t LF-60t VD-R11 Lianzhuo-VD Royal alloying process development and production of boron-containing steel, the technical measures for precise control of the smelting of boron-containing steel are analyzed and discussed.
The weldability of quenched and tempered GL-E40 hull steel plate is good. It means that under certain process and construction conditions, quenched and tempered GL-E40 hull steel plate can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like quenched and tempered GL-E40 hull steel plate, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.
