Recently, the large steel ingots of the first crankshaft of the mountain east and west special steel were successfully rolled off the line. This is the largest single-weight steel ingot currently produced by Xiwang Special Steel, with a single weight of 52.5 tons. It is mainly used for the crankshaft of large ships. The crankshaft is the power component that connects the ship's engine and propeller. The life of the crankshaft determines the life of the ship. This also marks a firm step for Xiwang Special Steel Co., Ltd. to vigorously develop high-end products in the field of marine engineering applications.
After inspection, the chemical composition, gas element and surface quality of the large steel ingot have met the technical requirements. Since Xiwang Special Steel is the first to produce large steel ingots of more than 50 tons, it has encountered many difficulties and challenges in the key process of production--release. With a total of more than 130 tons of molds, this poses a challenge to the spreader. After repeated discussions and drills, it successfully demolded once. This has also accumulated valuable experience for the production of larger steel ingots in the future.
It is reported that since the Institute of Metal Research of the Chinese Academy of Sciences and Xiwang Special Steel have fully cooperated, the ten core technologies have been used in the West King, which has enabled Xiwang Special Steel to quickly seize the technical commanding heights in the domestic special steel field and lead the deep transformation and upgrading of the steel industry. Up to now, the first special steel production line for clean and intelligent preparation of high-end equipment in China has produced more than 20 steel grades of various specifications such as slab, square ingot and round ingot, which are purely smelted and airtight in molten steel. Technological breakthroughs have been made in key process control such as pouring, and it is at the forefront of domestic steel industry.
