5.FAQ of  Continue Casting Steel Billets/Blooms Produced by  Blasting Furnace

 

We have organized several common questions for our clientsmay help you sincerely 

 

①How about your company

A world class manufacturer & supplier of castings forging in carbon steel and alloy steelis one of the large-scale professional investment casting production bases in China,consisting of both casting foundry forging and machining factory. Annually more than 8000 tons Precision casting and forging parts are exported to markets in Europe,America and Japan. OEM casting and forging service available according to customer’s requirements.

②How to guarantee the quality of the products

We have established the international advanced quality management systemevery link from raw material to final product we have strict quality testWe resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.

③Could I know the process of the producing?

Sure.Steel billet is produced by the method of through three processes: It is through the steelmaking system of continuous casting equipment, directly by the molten steel pouring into billet; The second is the steelmaking system in the production of steel ingot casting billet through system of steel rolling rolling equipment or processing of steel semi-finished products; Three is the steelmaking system production of steel ingot by forging the semi-finished product processing equipment.How to distinguish between the size of the inclusions? The size of the inclusion size, it is according to the slab is processed into finished products, whether affect the processing performance and can be divided into two micro inclusions and large inclusions.It is generally believed that inclusion particle size less than 50 microns, called micro inclusions size greater than 50 microns large inclusions.The inclusions in the continuous casting billet come from? Found in the continuous casting billet of inclusion complex, forms.Judging from the inclusion of ingredients, can be roughly know the source of inclusions. (1) the weak deoxidizing elements contained in the inclusion is more, and SiO2 + MnO content greater than 60%, the size is more than 50 microns, which can determine the inclusions are caused by air and molten steel secondary oxidation; (2) inclusion composition and refractory materials, with special shape, size is larger, can determine for refractory erosion;(3) inclusion contains such elements as potassium, sodium, is due to mould protection slag in molten steel.

Q:What is the approximate cost of billet to cold rolling?
The cost of billet to cold rolling is about 1000Galvanized to color coated sheet costs vary greatly, generally around 300, a high of 500
Q:Are billet metals within the metal range?
Ah, metal materials, ferrous metals, color metals, two kinds of billets belong to ferrous metals, copper and copper alloys, aluminum and aluminum alloys, belonging to color metal
Q:What is the active carbon. What is the difference with the charcoal?
Activated carbon activated carbon after activation of the solid carbon black porous. A general powder, granular or pellet, carbon as a main component, also containing a small amount of oxygen, hydrogen, nitrogen, sulfur and chlorine. The early production of activated carbon as raw materials for wood, hard shell or animal bone, later used by coal production method a: the steam and gas activation method. The use of water vapor or carbon dioxide at 850 ~ 900 C carbon activation.
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 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. Generally, the temperature decreases gradually during the rolling process (a small section of high speed wire has a temperature rising process), usually above 750 degrees
Q:How to calculate the cost price of billet?
The ratio of slag to billet (63% fine powder) is about 3:1, which accounts for about 60%. of billet cost
Q:Billet heating furnace prices?
The reheating furnace control mode according to the different tonnage, heating medium, price range, or recommendations according to your requirements, find good few industry units do offer the program, compared to eradicate the solution and quotation.
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:What does the billet of the steel plant refer to?And steel what is the difference?
Many species, usually by chemical composition, production process, rolling shape, supply form, diameter, and use in the structure the classification of steel bars for concrete reinforcement refers to straight or strip steel plate reinforced concrete reinforcement steel, its shape is divided into round steel bar and deformed steel two. Steel bars in concrete under tensile stress.
Q:What is alpha carbon? What is beta carbon?
The method of marking C is generally used in organic matter, and the C atom directly connected with the functional group is called alpha carbon.
