Q:Difference between medium frequency continuous casting billet and electric furnace continuous casting billet
3, intermediate frequency furnace can not decarburization, gas and inclusion content in steel such as H element content is high, the steel has high strength, hydrogen embrittlement characteristics, lower elongation, plastic failure, and electric arc furnace on the contrary.4, even smelting high carbon steel, alloy tool steel or casting, because of the above process defects, the quality of steel is still better than the electric steel, but sometimes the demand is not high, you can use
Q:Does anyone know how much it costs to refine a ton of steel? What are the expenses involved?
now the steel profits are not as good as before, a ton of net profit is about 100 yuan
Q:What about carbon 4 and carbon 5?
Carbon four is butane, which is made up of four carbon, divided into n-butane and isobutane.Carbon five is pentane, composed of five carbon, divided into pentane, isoamyl, and new pentane.A product of petroleum refining, usually consisting of alkanes with a greater number of carbon atoms.
Q:What is billet?
Steel billet is a product made by steel-making furnace by casting.The billet can be divided into two kinds from the manufacturing process, mould blank and continuous casting billet.
Q:Fish pole carbon cloth tcf. Vcf. Svf. Hcf. On behalf of what?
CF: is the abbreviation of Carbon Fiber in English, which means carbon fiber in ChineseCarbon fiber index for T (ton), ordinary carbon cloth is generally 20T-30T.Domestic ordinary carbon fishing rod material is generally 24T carbon fiber cloth. The higher the T value, the higher the strength and elasticity of the material.
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,
Q:Is the reaction of carbon and carbon dioxide a redox reaction?
The reaction of carbon and carbon dioxide is redox reaction.Turn left and turn right |Oxidation reduction reaction is a kind of reaction that changes the number of oxidation of elements before and after chemical reaction. The essence of redox reaction is the gain or loss of electrons or the offset of common electron pairs. The oxidation number of the element changes before and after the redox reaction.
Q:Who knows that the steel bar is always on the one side,
The rolling process of rolling mill of hot rolling and cold rolling process for the two step: a hot rolling process: from out of billet steel plant is only semi-finished products, to the rolling mill for rolling, in order to become a qualified product.
Q:What is the difference between steel and billet in the process?
Square is a square steel hollow, with iron produced; but it is a square steel billet is generally solid, forging or casting molding.
Q:How does billet caster pull out billet cracking?
If it is a surface crack, it is necessary to take slow cooling measures to the entrance and exit of the mold and minimize the harmful elements such as parathion
