1. Calcined petroleum coke recarburizer, because it has not undergone high temperature treatment, the calcining temperature is low, the time is short, and the sulfur content is high. It is impossible to draw clear marks on thin paper, and the absorption rate is about 80%. Generally, the application of castings and gray iron castings manufacturers is better. High temperature asphalt

2. High-temperature calcined petroleum coke recarburizer, the nitrogen content is lower than that of calcined petroleum coke recarburizer, and the sulfur is also much lower than that of calcined petroleum coke recarburizer. Clear marks can be left on thin paper, and the absorption rate is above 85%-90%. Generally, the application of castings and gray iron castings manufacturers is better.

3. High temperature calcined petroleum coke recarburizer, as a good quality recarburizer, the nitrogen content is 100ppm. The sulfur is lower than the previous one. The absorption rate is above 90-95%. There are more on the ductile castings

Petroleum coke recarburizer

The recarburizer does not need to be added to the furnace bottom first. Because of the high melting point of the recarburizer, it is slowly dissolved, digested and absorbed by the surrounding of molten iron. Therefore, if the furnace bottom is added immediately, it will not only increase the dissolution time of the recarburizer, but the high temperature of the accumulation can also reduce the furnace Fire the honeycomb at the bottom and burn through the bottom of the furnace. Therefore, when there is a small amount of molten iron at the bottom of the furnace, the recarburizer should be added together with the waste steel, and strive to end the addition of the calculated recarburizer when 3/5 of the refurbished waste is added. More and more customers are looking forward to finding a good graphite recarburizer manufacturer to carry out collaborative purchases, but the sales market is very large. It seems that it is not so easy for a carbon manufacturer to choose a good graphite recarburizer, and it must be all-round. Taking into account that not only the products, but also the service items, technical expertise, scale of operation and other factors, a good graphite recarburizer manufacturer not only has good product quality, but also the preparation work before the original factory is still seriously and meticulously undertaken. Such a manufacturer Let every customer feel at ease and have a sense of trust in the aspect ratio. Recarburizers are divided into recarburizers for ironmaking and recarburizers for pig iron. Other additional raw materials are also effective. They are effective for recarburizers, such as automobiles. Anticorrosives for brake pads, as wear-resistant materials, recarburizers belong to the extra recarburizing raw materials for ironmaking and steelmaking. High-quality recarburizers are auxiliary preservatives that cannot be lacked in the production of heat-resistant cast iron.

The steel manufacturing companies in China have clearly stated the technical standards for the purchase of recarburizers, which stipulate a lower sulfur content, which is actually not necessary. The liquid sulfur content is less than 0.05%, which causes poor quality of cast iron and destroys the quality of synthetic cast iron. Therefore, the sulfur-increasing processing technology has been developed along with it. Because synthetic cast iron has been developed, there are many problems in the production of cast iron. The selection of waste steel and recarburizer processing technology and sulfur processing technology, coupled with excellent quality, is an indispensable and sufficient processing technology countermeasure for the current stable production of high-quality gray iron parts.
