Product Description:

Construction building material galvanized color prepainted cold

rolled steel coil

 

Prepainted steel sheet is coated with organic layer, which provides higher anti-corrosion property and

a longer lifespan than that of galvanized steel sheets.

 

The base metals for prepainted steel sheet consist of cold-rolled, HDG electro-galvanized and hot-dip

Alu-zinc coated. The finish coats of prepainted steel sheets can be classified into groups as follows:

polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc

Q:How do steel billets come out?
I. mining1, iron ore2 limestone mine3, coal mineTwo 、 burden preparation1. Iron ore sintering2 coking coal cokingThree, iron: in the blast furnace, sintering iron ore, limestone, coke, iron ore in the iron elements reduced to metal iron, then the product is pig iron.
Q:Billet market trend
3, Tangshan billet inventory declineIt is understood that in April, the Tangshan region began to decline in the stock of major steel warehouse, as of April 28th, Tangshan billet inventory at about 1 million 250 thousand tons, a drop of about half higher than the high point. But some vendors have revealed that some of the resources are being transferred from the warehouse to the traders. In fact, inventories are much larger than statistics, and the inventory of 1 million 250 thousand tons of steel is about 2.5 times that of the same period of last year.In addition, network analyst China industry insight believes the macroeconomic situation, the weakening of steel and steel industry more negative news of the credit crisis will be unfavorable to the billet market outlook. But considering the steel production has been at a loss, the billet has a certain resilience; and before the May Day holiday billet prices fell rapidly, it is possible to pull up the opportunity to play after the manufacturers in a certain way.
Q:The form of carbon in carbon steels
There are three solid solutions of carbon in iron: alpha solid solution (Tie Suti), gamma solid solution (austenite) and delta solid solution (8 ferrite). The spatial distribution of iron atoms in these solid solutions is consistent with that of alpha -Fe, gamma -Fe and delta -Fe. The size of carbon atoms is much smaller than that of iron atoms.
Q:What is the billet price in China today?
In the short term is still the main shock, the domestic price rise compared to the previous 10 yuan / ton, the price is not the same in each region, so you still have to carefully check the price, from the upstream iron ore, domestic ore prices stabilize, without much change, with the real estate back to temperature.
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:What is the active carbon. What is the difference with the charcoal?
This decision of the activated carbon has Good adsorption of metal ions, adsorption, wastewater and waste gas in the harmful gases, organic pollutants, such as pigment. Application of activated carbon also requires high mechanical strength, good abrasion resistance, its structure to stabilize, adsorption energy required, to facilitate the regeneration. The active carbon used for oil, beverage, food, drinking water, decolorization, deodorization, gas separation, solvent recovery and air conditioning, adsorbent is used as a catalyst carrier and a gas mask. Charcoal is made from trees and dry, is a kind of fuel. Soil general burn charcoal, is placed in a kiln inner wood, after the ignition, when he arrived a certain temperature, closed kiln inlet, let the heat get distillation of wood and charcoal. To serve the people of Zhang Side is burning charcoal, charcoal kiln collapsed when.1 died
Q:What about carbon 4 and carbon 5?
Carbon four is butane, C4H10 carbon five is pentane C5H12
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:How does billet caster pull out billet cracking?
There are many kinds of cracks. Which one are you talking about? It is related to the water radian of the crystallizer.
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
