Use of petroleum carburant in casting process

Date:2017-08-25 Author: Click:

If the slag remover is used in the casting of petroleum carburant, it will float on the surface of the metal. The effect on the metal is to keep it warm. The main purpose of steelmaking carburizing agent is to use metal that needs to be exchanged in the middle. Then it's very simple to use it, either manually or with an airbrush. When the residue is cleaned up, the industrial slag remover is evenly spread over the surface of the solution, and then stirred. Before pouring after slag removal, adding large-scale slag removal agent in ladle or furnace can form a floating layer on the surface of metal solution, which can stick off the scattered slag dissolving, save the artificial slag stopping and improve the production efficiency. According to the need, a floating layer or a striped scum can be formed in the ladle and the furnace to efficiently block slag. Slag remover can be used in the smelting process of ferrous metal hot working industries such as blast furnace, converter, refining furnace steelmaking, iron casting and steel casting, etc. It can adjust the hard-to-treat slag formed in the smelting process and agglomerate it into a thick and plastic slag layer. Thus, the slag formed during the smelting process can be conveniently, completely and cleanly removed. Avoid casting slag, reduce casting scrap rate. The utilization ratio of smelting metal is increased, the casting quality is improved, the energy consumption is reduced, the operation period is shortened and the operation is convenient. Convenient slag smelting is the need for attention, and this work is carried out when the temperature is very high. Slag remover has obvious slag collecting function for ferrous metal. Carburizing plant

Carburizing agents such as graphite electrode or graphitized oil coke should be selected as far as possible because graphite carburizing agents have high absorption rate, fast dissolution speed, which is conducive to reducing energy consumption, and can effectively increase the nucleation core of molten iron, improve metallurgical quality, and select carburizing agents with lower impurity elements such as sulfur and nitrogen. The use of different carburizers will have different costs and effects, so consumers need to understand the classification of carburizers, choose the most suitable products.

Artificial graphite is the best quality graphite carburizer, but its price is relatively expensive, so it is often used in the production of high quality products, such as ductile iron production will use it. Petroleum coke is the most widely used carburizer, its cost is relatively low, and the output is very large, so it is favored by many consumers, especially in the aluminum industry is very much used.

Petroleum carburizing agent

Natural graphite is also a carburizing agent, it can also be divided into flake graphite and microcrystalline graphite, but the ash content of microcrystalline graphite is high, so generally not used as a carburizing agent for cast iron. There are many varieties and characteristics of flake graphite. Coke and anthracite are commonly used as carburizers in EAF steelmaking, but they have high ash content and many volatile components, so they are not used very much. There are many kinds of carburizing agents, but why should graphitization carburizing agents be used when casting electric furnaces?

Because flaky carbon atoms are the best core of graphite-shaped cores to facilitate graphitization, high-quality graphitizing carburizer sulfur content decreases as sulfur dioxide gas escapes from the original disordered arrangement of carbon atoms into flaky arrangement after high-temperature graphitization. Usually very low, generally less than 0.05%, better or even less than 0.03%, is also an indirect indicator to judge whether the graphitization is good or not after high temperature graphitization treatment. The fruit is quite different.
