Smelting process of KD cable laying ship steel, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.
Since it was established in 2000. Based on the domestic rich KD cable laying ship steel product resources and the great steel demand of the international market, our KD cable laying ship steel service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
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 KD cable laying ship steel 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 KD cable laying ship steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
KD cable laying ship steel, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.
Our company will accept the product quality objection registration record, pass it to the KD cable laying ship steel production unit and relevant departments, and timely coordinate the supervision of product KD cable laying ship steel quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
