Welcome to inquire! Contact: Simon / R. How rational use of die steel rolled plate and forging module, forgings? A: The market is well-known materials such as imported brands 1.2738,1.2311,1.2312, SP300, SP350 and other steel grades 2738, its essence is forging pre-hardened module. So, what module and plate rolling difference? Judging from the production process, will be able to glance: the production process modules: EBT EAF (to avoid oxidation slag into the ladle refining process steel slag separation method) / LF refining (use a ladle of molten steel refining) → VD vacuum degassing gas (reduce the amount of steel H reduce cracking, shrinkage, skin bubbles, central loose steel) / argon casting / slow cooling annealing / ingot finishing / ingot heating / 3150 ton hydraulic press forging / heat / four roughing / testing → both ends of the cutting / delivery. Rolled plate production process: A, furnace / secondary refining / casting / rolling; B, BF / hot metal pretreatment / converter / secondary refining / casting / rolling; for cement processing equipment covers plastic box questions and produced covers cultural workers is not high quality, low yield formation of cement covers goods imported 2738 materials, substandard quality of goods, although the state has adopted a certain standard, but in fact does not alter the substance of doubt, in the production of cement covers plastic box covers the process, because the machining precision machining quality improvement, cement covers commodity products ahead in the industry. Technical and economic function is an inductive goal imported from Germany 2738, 2738 plastic boxes economy excellent price, but also need to be considered along with the cost of equipment, the economic function, ergonomics, from the quality of personnel to use the machine, methods of operation, plastic to replace the mold box maintenance, safety and security considerations, down labor costs, reducing equipment complies with, this is the ideal situation modernization of the company to improve product quality and production environments.
