What should the petroleum coke recarburizer manufacturer do when the casting effect is not good?

In the process of petroleum coke recarburizer, the application of recarburizer goods is very common. However, sometimes the expected effect cannot be achieved when applying recarburizers. The following is a three-point finishing method collected by Jilin Kunlang Carbon Products Co., Ltd. for your reference: Carbon fiber spun pitch


1. Purchasing recarburizers according to the forging application furnace


Recarburizer is an indispensable raw material for the concentrator during calcination. Therefore, you must carefully select the recarburizer. You should choose the recarburizer that is suitable for your common furnace during calcination to exceed the expected effect.

2. The moisture content of the recarburizer should meet the application requirements


When buying recarburizers, processing plants must first clearly specify the water content. You cannot buy semi-high purity graphitized recarburizers blindly from the crowd, but generally you should choose low-sulfur and low-nitrogen enhancers to reduce the moisture content of harmful substances in order to guarantee iron castings. quality.


Ferrosilicon 65 purifies molten steel: In the actual steelmaking process, many oxides are often seen floating on the surface of the molten steel. If it is not cleaned up, it will greatly affect the quality of the steel. Putting ferrosilicon 65 in the steelmaking process can be effective To solve this problem, the elements of ferrosilicon 65 melted in the molten steel can react with oxides and accumulate a large amount of oxides. This makes it easier to filter and purify the molten steel and improve the quality of the finished steel.


In the smelting process of anthracite recarburizer manufacturers, due to unreasonable ingredients or charging and excessive decarburization, sometimes the carbon content in the steel cannot meet the higher cycle requirements, and carbon should be added to the molten steel. . Common carburizing agents include carburizing cast iron, electrical grade powder, petroleum coke powder, carbon powder and coke powder. When smelting medium and high-carbon steel in a converter, petroleum coke with less residue is used as a recarburizer. The top-blowing converter steelmaking regulations for carburizing agents are: high carbon sequestration, low ash content, high volatile content, high content of residues such as sulfur, phosphorus, nitrogen, etc., dryness, cleaning, and moderate particle size. The fixed carbon component is: carburizing agent w(C)>96%, volatile content≤1.0%, w(S)<0.5%, w(moisture)<0.55%, particle size 1-5mm. The particle size is too fine, easy to ignite, too thick, floats on the surface of the molten steel after adding, and is not easy to be digested and absorbed by the molten steel. The grain size of the induction furnace is 0.2-6mm, in which the grain size of steel and other light metals is 1.4-9.5mm, and the high carbon steel requires low nitrogen, and the grain size is 0.5-5mm. Judgment and selection of specific types and other details.
