Production technology of high strength steel strip packing

High strength steel strip production technology of 1 packing. Production process of blast furnace hot metal - Mixer - Converter - The ladle refining furnace - Continuous casting - Casting billet - Heat - Test - Packaging - Rolling - Test - Packaging - Cutting - Annealing - Test - Put in storage. 2. Production process of converter adopts 900 mpa steel strip steel converter smelting, with silicon, aluminum, barium deoxidization and ladle argon blowing process, the R9m casting square billet continuous casting machine, according to the hair with high tensile strength, suitable elongation requirements, the main ingredient in steel making appropriate adjustments. Mixer - process routes of the converter Converter - Stand - argon blowing 如果- - - - - - Continuous casting machine. The requirement of smelting 1. New furnace top 20 furnace, furnace lining first sleep 5 furnace, furnace body and the oxygen lance, smoke hood system leakage is not allowed smelting steel 2. Refining in the pulp are thoroughly to ensure the removal of phosphorus and sulfur. 3. Ban after blowing up. 4. To fine-tune composition adopts refined, according to the composition of molten steel, make its ingredients into the target elements of 900 mpa steel requirements. 5. 900 mpa steel strip of the liquidus temperature of 1500 degrees Celsius, the outbound LF furnace temperature is 1580 - After 1590 degrees Celsius, refining on continuous casting.
