Q:What is the drop per minute of the billet temperature at 850?
Cold rolling is not considered. The initial rolling temperature (surface) of the billet is generally 1000-1150 degrees.
Q:What are the causes of internal cracks in continuous casting billet?
A French Research Institute of carbon, sulfur and phosphorus influence on continuous casting billet hot cracking, a total of three test groups of carbon manganese steel, carbon, sulfur and phosphorus content of each sample is different.
Q:What is carbon accumulation?
Generally refers to the polycarbonate, PC, is a kind of thermoplastic plastics, good transparency, good mechanical properties, surface hardness, common uses such as CD, plastic glasses, a fence, protective window, public places, vacuum cleaners, coffee machine, juicer barrel, refrigerator shelf, pure such as the bucket.
Q:Are billet metals within the metal range?
Two kinds of billets, ferrous, ferrous and metallic, belong to ferrous metal, copper and copper alloy, aluminium and aluminium alloy, and belong to colored metal
Q:What do you mean by adding carbon to a table tennis racket?
What a professional? I don't know what is known but with carbon carbon line take this hit the ball the more comfortable to take shape
Q:Is the reaction of carbon and carbon dioxide a redox reaction?
According to the increase or decrease of the oxidation number, the redox reaction can be split into 2.5 reactions: the half reaction of increasing oxidation number is called the oxidation reaction, and the reaction of reducing the oxidation number is called the reduction reaction.In the reaction, the oxidizing substance, called the reducing agent, forms the oxidation product. The reducing reaction substance is called the oxidant, and the reduced product is produced. The oxidation product is oxidized but weaker than the oxidant; the reducing product is reductive but weaker than the reducing agent.Whether a chemical reaction belongs to an oxidation-reduction reaction depends on whether the reaction has an increase in the number of oxidation, or whether there is an electronic gain or loss.Turn left and turn right |In this reaction, carbon dioxide carbon has a valence of +4 price, after the reaction of carbon monoxide in the carbon price is +2, the carbon dioxide is reduced to carbon monoxide; elemental carbon has a valence of 0 by the price to rise to +2 price, is oxidized to carbon monoxide; carbon is oxidized to carbon dioxide reduction.
Q:The form of carbon in carbon steels
There are three solid solutions of carbon in iron: alpha solid solution (Tie Suti), gamma solid solution (austenite) and delta solid solution (8 ferrite). The spatial distribution of iron atoms in these solid solutions is consistent with that of alpha -Fe, gamma -Fe and delta -Fe. The size of carbon atoms is much smaller than that of iron atoms.
Q:The role of carbon content in steels
Therefore, the carbon content determines the use of steel: low carbon steel (carbon content < 0.25%), commonly used as extrusion and stamping materials; carbon steel (carbon content < 0.6%), commonly used as mechanical parts; high carbon steel (carbon content > 0.7%), commonly used tools, tool and mould etc..
Q:What does the billet of the steel plant refer to?
The steel billet is the continuous casting machine by smelting steel plant casting into the blank, in the middle of products before entering the rolling process, the section size will be decided by rolling steel.
Q:Continuous casting billet has slag inclusion and air hole
In the production process of steel castings, the appearance of quality defects is unavoidable. It is essential to take reasonable measures to avoid the inclusion of slag in the cast steel. It is necessary to understand the reason why the porosity of the cast steel is caused by slag inclusion so that the quality of the cast steel can be improved.In order to solve the pinhole of slag phenomenon, the first thing to do is to understand the cause of steel casting porosity slag phenomenon, and take corresponding measures according to the original material,
