Industrial Kilns Carburizer for Carbon Additive ISO9001 Certified and 0.5% Max Ash Content

 High quality factory price industrial kilns Carburizer,carbon additive

Carbon additive Graphitizing carburizer: petroleum coke is a by-product of refining crude oil. Residuum and petroleum asphalt obtained by constant pressure distillation or vacuum distillation of crude oil can be used as raw materials for manufacturing petroleum coke, and then raw petroleum coke can be obtained after coking. The production of raw petroleum coke is less than 5% of the crude oil used. Raw petroleum coke has a high content of impurities, so it can not be used as a carburizer directly, but must be calcined first. Petroleum coke is calcined to remove sulfur, moisture and volatile matter. Calcining crude petroleum coke at 1200-1350 ℃ can make it a basically pure carbon. However, the content of sulfur and nitrogen can not meet the production requirements of high quality cast iron products. Therefore, it is necessary to obtain lower sulfur and nitrogen content under higher temperature. It also makes the arrangement of carbon atoms show the micro morphology of graphite. More conducive to the improvement of cast iron quality. And this high temperature treatment process is called graphitization.

Usage of Carbon additive

1. Process of adding carburizer with furnace

1) Charging sequence for cold furnace condition - add according to the mode of "scrap + ferromanganese + carburizer + scrap + recycle + scrap + pig iron + ferrosilicon";

2) Charging sequence of hot furnace situation - about 300kg of molten iron is left at the bottom of the furnace, which is added in the way of "scrap + ferromanganese + carburizer + scrap + recycle + scrap iron + pig iron + ferrosilicon";

3) If scrap is pressed with scrap, it may not be practical to add scrap directly to the bottom of the furnace at first. Therefore, according to the actual situation of the plant, it is added in the way of "recycle + ferromanganese + carburizer + scrap + recycle + ferrosilicon";

2. Application process of carburizer in fine adjustment

After the molten iron is melted, in the case of insufficient carbon content in the molten iron, fine adjustment and carburization are needed to meet the process requirements. At this time, it is generally hoped that the carburizer can quickly achieve the effect of carburization, so as to avoid the influence of too long treatment time on the metallurgical quality of molten iron. At this time, the instant graphitizing carburizer should be added to the molten iron surface, and the iron can be produced within 1-2 minutes after proper stirring.

Matters needing attention:

1. The carburizer shall avoid direct contact with the furnace bottom lining material to prevent the carburizer from eroding the furnace lining;

2. The carburizer shall be avoided to be added together with iron chips as far as possible to prevent the agglomeration of the carburizer and other materials from affecting the absorption of the carburizer;

3. If the amount of carburizing agent is too large in the production process of all scrap, it is not suitable to add all of them. It should be added gradually and layer by layer.
