Environmental protection targeting on the iron and steel industry

During the period of "Thirtieth Five-year” iron and steel industry will become the environmental governance key areas, with China’s efforts to promote the excess capacity solving, many iron and steel enterprises which can't meet the requirements of environmental protection will gradually quit the market.

Director-general of the department of ministry of energy saving Gao Yunhu said on the BBS, during the period of "Thirtieth Five-year" and in the process of promoting industrialization, our country will pay more attention to ecological civilization construction at the same time, at present, our country did not get rid of the extensive pattern in energy intensive and highly polluting, such as iron and steel industry compared with the international advanced level of energy efficiency is nearly 10% of the gap, narrowing the gap to meet the requirement of ecological civilization construction.

As the energy conservation laws and regulations updated during the period of "twelfth five-year", energy-saving standard binding will be further strengthened during the period of "Thirtieth Five-year". According to the plan, the steel industry will much tighter emissions standards, sintering machine head particulate matter, iron particles sintering head main emissions standards, such as sulfur dioxide will decrease by 60%, 92% and 60% respectively. "Regardless of the size, enterprises will be run according to the standard, violate compasses to punish the illegal cost is much higher than the cost of compliance."Gao Yunhu said.

Planning institute director li xinchuang metallurgy said, the future will be subject to strict control iron and steel enterprise development scale, industry development will enter the low speed or reducing development; Raised environmental standards will lead to certain changes in energy consumption structure, forced coal use decline; To speed up the backward capacity elimination and the production structure adjustment will lead to can't meet the requirements of environmental protection enterprises gradually quit the market.

Influence of energy price fall for Nippon steel

Nippon steel, Japan's largest steelmakers expects that oil drilling industry with the demand of the seamless steel pipe is expected to decline 30%, but energy consumption reduction can offset the impact of falling demand.

Nippon steel is one of the world's major seamless steel pipe manufacturers, its main competitions are France steel pipe manufacturer tile Lu Ruike and Turner in Italy.

Nippon steel relevant personage says, the company plans to compress costs 50 billion yen this year, and will do their best to improve the overseas business profit at the same time, want to keep in the growth of the past three years.

Relevant agency predicted, this year's profits of Nippon steel will be increased by 6% up to 485 billion yen level, the contribution of the steel pipe business may be more than 20%.

Global crude oil prices achieve its lowest level in March this year for six years.

However, although energy prices fall results in a decrease of steel demand, it also lead to a lower production cost, such as the sea freight, as well as road transportation cost of the product is substantially reduced, Nippon steel hope the reduction of the cost is able to make up for the decline in profits from sales.

Thermal expansion seamless steel pipe market analysis

April is the traditional peak season of thermal expansion seamless steel pipe, but this season is not flourishing, steel market trend is still weak.

Some operators think steel market is still difficult to recover in May, however, thermal expansion seamless steel pipe price fall space is limited, or there will be a stop falling stabilization, steady rise in market and the overall better than April.

Specific reasons are as follows:

One, inventory is a steel inventories moved forward, steel plant to grow, the price war smoke rise;

Two, the thermal expansion seamless steel pipe production release production, output growth, excess supply to continue;

Three, is the downstream terminal demand situation change has yet to be observed;

Four, is the iron and steel materials such as iron ore market changes affect steel market;

Five, steel mills adjust price policy, influencing late thermal expansion seamless steel pipe market.

Considering above factors, it is expected the it’s difficult to "fire" in May, but will be somewhat better than in April, rebar, wire rod, hot-rolled coil, plate, thermal expansion seamless steel pipe price or will shake up.

Demagnetization of SSAW steel pipe

In the pipeline industry, we are often encountered with magnetic steel pipe, steel pipe with magnetic and without demagnetization operation is hard to weld, and the welding precision is not high, therefore, steel pipe with magnetic must carry out demagnetization.
Steel demagnetization is actually very simple, can be divided into simple demagnetization and complex  demagnetization:
1, simple demagnetization: demagnetization coil wound on the pipe outside, alternating current on the coil, slowly decrease the AC (the slower the better), until reduced to zero. At the end of demagnetization. Results: not change the physical properties of the steel pipe, but once met the outer magnetic field again, the steel will be magnetized.
2, complex demagnetization: the heat treatment process can completely realize demagnetization, however, after the demagnetization of degaussing, hardness and rigidity of steel pipe will change, once meet the external magnetic field, after the magnetic field disappeared, the steel pipe will basically no remanence.
According to the above two kinds of way of steel demagnetization - single demagnetization and complexde magnetization, there is a common point that it can not contact with the strong magnetic field after the demagnetization, otherwise it will be again magnetized.
At present, large diameter SSAW steel pipe generally uses DC demagnetization coil, the demagnetization coil is added into the magnetic particle inspection machine, but the demagnetizing effect does not satisfy the customer, the problem lies in the DC demagnetizing field only generates half cycle reverse magnetic field, only can offset reverse part of the internal remanent large diameter SSAW steel pipe, its remanence stays within the required range, so the effect is not very stable. It can be achieved in the field, after handling, beaten, and exceed the standard magnetic field again. The reason is that the domain of large diameter spiral pipe to demagnetization without "internal magnetic exercise" is not very stable.
Large diameter SSAW steel pipe demagnetization
Remanence national standard is below 30GS, HT30D steel demagnetization system can be stable to pipe remanence of about 10GS, to avoid rebound of the remanence in the process of transportation.
Size specifications: 400*500*600mm
Working voltage: 220V
Working current: 5-20A continuously adjustable
Working frequency: 0-50Hz continuously adjustable
Demagnetization coil diameter size: 100-250 (according to customer requirements).
