Specifications

square steel billets 
1)We procure world class quality steel billets which meets the specific requirements of the clients

The Billets produced by the company can be broadly divided into three main types i.e.

  1. M.S. Billets

  2. CRS Billets

  3. Special Alloy Billets

M.S. Billets are used for rolling of TMT Re-Bars of Fe415 and Fe500 Grade and various other structural steel products.

CRS Billets are used fro rolling of CRS TMT Re-Bars.

Special Alloy Billets are used for rolling of any special grade TMT Re-Bars like Earthquake resistant TMT Re-Bars and for special grade structural steel products.

The following are the sizes of Billets available with Shyam Steel Industries Ltd.:

  • 100 X 100

  • 120x120

  • 150 X 150

Q:How are the billets classified?
According to the specifications are divided into: billets, billets, round billet, rectangular billet and slab. According to the steel grade: Q235, Q195, GCr15 and so on........................
Q:Billet market trend
1, domestic crude steel production remains highAlthough the recent domestic steel market has been relatively low, and the loss of steel mills win less, 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.
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: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:If the casting speed is not steady, what will happen to the billet?
The instability of the casting speed leads to the unstable surface of the mould and increases the probability of slag entrapment in the mold.
Q:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
This depends on the intermediate frequency furnace voltage level and inverter efficiency, the general high voltage will save power, generally 550-700 range, details can refer to wcdlsb.net site medium frequency furnace data
Q:What is the difference between continuous casting billet and cast billet?
Mainly to see the process, general casting efficiency is low, but the quality is acceptable, with low level (open casting billet) has great advantages in surface quality; but with high-grade continuous casting line (full protection casting, electromagnetic stirring, liquid stopper control) compared both have a big difference in the crystal, oxidation, surface quality.
Q:The role of carbon content in steels
2., the formation of carbide structure, can improve the hardness and wear resistance of steel, such as cementite, or Fe3C, that is, carbide organizationTherefore, the higher the carbon content in carbon steel, the higher the strength and hardness of the steel, but the plasticity and toughness will also be reduced. On the contrary, the lower the carbon content, the higher the plasticity and toughness of the steel, and its strength and hardness will also decrease
Q:Billet heating furnace prices?
Look at the video case, you can consult the advisory.
Q:How can carbon and carbon in a fishing rod be distinguished?
When it comes to the differentiation of carbon fishing rods, first of all, what are the different kinds of fishing rods containing carbon?!Carbon rod is now sold in the market are divided into three kinds, namely: carbon, pure carbon, high carbon. These three categories.1, carbon packaging, as its name implies, two layers of material, the outside layer is carbon cloth, the inside layer is glass fiber, epoxy cloth. The price of this kind of rod is lower, because it is not necessary to buy a brand because of the lower price. With a few times you can change, for beginners.2, pure carbon refers to the overall use of 30T below carbon cloth fishing rod, general 24T, 30T based, carbon content of more than 98%. Moderate price.3, high carbon refers to the overall use of more than 30T carbon cloth fishing rod, but not the whole fishing rod is made of a carbon cloth. The tonality of a fishing rod is actually modulated by a different modulus of carbon cloth.Some fishing overall with the 30T following carbon cloth, just use a very small amount of 40T or 46T carbon cloth, called high carbon rod, is actually confuse the public practice of fishing by weighing, hand identification, high carbon rod with real light, hard, two rods in a play, a ratio is obvious.
