Alloyed Steel Bloom by Blast Furnace with Chromium

 

1.Structure of Alloyed Steel Bloom by Blast Furnace with Chromium

 

Steel Blooms Manufactured by Continue Casting is the raw material of all kinds of steel mill. Bloom section of square, round, flat, rectangular and abnormity, etc Several, mainly related to shape of rolled products. Simple rolled section steel, choose cross section of square Bloom or rectangular Bloom. rolling The sector products such as flat steel, Angle steel, select the rectangular Bloom or slab. Had better profiled Bloom when production beams, channels, and in rolling process Lines and improve the yield. The raw material of round Bloom is the production of seamless tube. 


2.Main Features of Alloyed Steel Bloom by Blast Furnace with Chromium.

Steel Blooms Manufactured by Continue Casting section size should meet the requirements of rolling deformation and finished product quality, but also roll strength and biting condition of restrictions. General steel Bloom section height H. And the roll diameter D The ratio of the ( namely H/D) Should be less than or equal to zero 0.5 . Length of steel Bloom by finishing temperature, Rolling time and the length of the product Or times ruler. When heated too long accident prone to bump the furnace wall of steel, too short, furnace bottom utilization rate is not high, influence the heating furnace production. For the production Choose a variety of steel and steel Bloom, should consider the affinities of Bloom, as far as possible in order to improve the productivity of the roughing mill, simplify the stock management of workshop.

      There are three shapes of the steel Bloomssquare Bloom, slab, rectangular Bloom The Chinese Bloom, rectangular Bloom is mainly suitable for rolling hot rolled strip, building reinforced bar, Ordinary wire, high speed wire rod and various small profile. Of the slab are mainly used for rolling plate and hot coil sheet.

Q:20 what is the difference between manganese silicon steel billet and Q235 billet?
In brief, the ingredients are different and the uses are different.20 manganese silicon steel billet for high strength steel,Q235 billet is almost the most common steel, requiring the lowest.
Q:Can the production of continuous casting billet be damaged by using intermediate frequency electric furnace?
If there are no other major facts of harm, it seems that there is no such mandatory legal provisions to bear criminal responsibility. Mandatory closing and fines at most.
Q:The form of carbon in carbon steels
The solubility of carbon content when the iron carbon alloy than in the iron when the excess carbon can be in the form of carbide iron or elemental state (graphite) in alloy, which can form a series of carbide, Fe3C (cementite, 6.69%C) is a metastable phase, it is a compound complex structure gap. Graphite is a stable phase of iron carbon alloy with simple six - party structure. Fe3C has the potential to break down into iron and graphite stable phases, but the process is extremely slow at room temperature.
Q:Difference between medium frequency continuous casting billet and electric furnace continuous casting billet
5, if the intermediate frequency furnace supporting a reasonable refining facilities, also can produce high quality steel, even more than the electric arc furnace steelmaking, specific processes can be used: +VOD+LF process of intermediate frequency furnace can produce very good steel.
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: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:Charcoal is how to
Now, there is a method of using sawdust and other waste materials to process the charcoal, which is formed by pressing the waste materials into the furnace and heating them indirectly. The raw materials are carbonized into charcoal.The quality of charcoal can only be raised according to different uses.
Q:Billet rolling temperature
The final rolling temperature is the rolling temperature of the last pass, and also the rolling temperature of the rolling pass at the last effective (very small level pass, not an effective rolling pass)
Q:How many tons of billets does it take to produce a ton of thread steel?
The yield was increased, consumption will be reduced.
Q:Difference between billet, slab and billet
Production process of billet is through three methods: one is through the production of steelmaking and continuous casting equipment system, the molten steel is directly cast into the billet; two of steelmaking production systems of steel ingot or billet by rolling system of steel rolling equipment processing semi-finished products; three is the production of steelmaking system by forging semi-finished steel ingot the processing equipment. Market trends 1, domestic crude steel production remains high, although the domestic steel market has been relatively sluggish in recent times, and steel losses are more, but this does not seem to affect the enthusiasm of steel production. According to the China Steel Association statistics show that: in early April, the daily output of crude steel in key enterprises in China was 1 million 697 thousand and 300 tons, and the average daily output of crude steel in China was estimated at 2 million 123 thousand and 900 tons. And in mid April, crude steel daily output of ten days, although there has been a drop back, but still at a high level. According to statistics, in mid April, the average daily output of crude steel in key enterprises nationwide was 1 million 689 thousand and 100 tons, and the average daily output of crude steel in China was estimated at 2 million 115 thousand and 800 tons. Such a large production and sluggish demand in stark contrast, which is a drag on steel prices down one of the important factors.
