Structure of Prime quality square alloy steel billet 150mm Q235

 Prime quality square alloy steel billet 150mm Q235

Description of Prime quality square alloy steel billet 150mm Q235 

1. Prepainted steel coil is coated with organic layer, which provides higher anti-corrosion property and a longer lifespan than that of galvanized or galvalume steel sheets. 

2. The base metals for prepainted steel coil consist of cold rolled, HDGI Steel, electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of prepainted steel coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

4. The color of the prepainted steel coil has a very wide selection, like orange, cream-colored, dark sky blue, sea blue, bright red, brick red, ivory white, porcelain blue, etc.

5. The prepainted steel coils can also be classified into groups by their surface textures, namely regular prepainted sheets, embossed sheets and printed sheets.

Q:Can the production of continuous casting billet be damaged by using intermediate frequency electric furnace?
No, as long as the quality of the billet is OK
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: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: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 site medium frequency furnace data
Q:Charcoal classification
Hard charcoal. By hardwood such as Fagaceae Quercus, Castanopsis trees, secondary birch and etc..Broad-leaved charcoal. Charcoal made from a mixture of hard and soft hardwood.Pine charcoal. Carbon fired from pine or other needle wood. In addition to bamboo and bamboo charcoal burning with shells, stones (coconut shell, peach stone charcoal etc.) wood raw material firing. Charcoal collected from household stoves in the cell known as carbon. If the charcoal is crushed and mixed with proper adhesive, and then pressed, formed and roasted, the deposit is made. According to the burning process of silica and carbon black.
Q:How to purchase suitable billet heating furnace
Choice can not be blind, you can not just look at the price, the choice of advice you consult more manufacturers, and then use the exclusion method to determine your final goal. Online can take a look at live video, more reference.
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?
Look at the video case, you can consult the advisory.
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.
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. The C atom separated from the functional group is called C beta atom, and alpha carbon and beta carbon are not unique
