Japanese steel exports increased by 2.3% in July

According to statistics released by the Japan Iron and Steel Federation (JISF) on August 31, in July this year, Japanese steel products exports increased by 2.3% year-on-year to 3.03 million tons. Earlier last year, the plate product that was shrinking due to a fire accident at the Oita Works's plate production line saw a 76.8% increase in July this year, which led to an overall increase in Japanese steel exports. . However, although the plate boosted the entire steel export, the export volume of other core products such as hot-rolled steel sheets and steel strips was still less than 1 million tons, so Japan's steel exports have not yet returned to normal. Analysts believe that the main reason is that Japanese steel companies have shifted their sales focus to the domestic market. According to JISF data, Japanese steel inventories remained at 5.671 million tons in July, a decrease of 254,000 tons from June. JISF explained that the decline in steel inventories in July wa...

U.S. raises tariffs, Turkish steel exports are blessed in disguise

According to foreign media reports, after the United States doubled the tariff on Turkish steel products, Turkish steel products were basically rejected by the US market. Therefore, Turkish steel products have to be turned to other countries for export. However, from the data point of view, Turkish steel exports are blessed in disguise. The largest exporter of Turkish steel last year was the United States, with Israel and Italy ranking second and third. However, due to the high steel tariffs imposed by the United States, from January to May this year, Turkish steel exports to the United States were less than 500,000 tons, less than half of last year. On the contrary, Turkey’s steel exports to Italy and Spain have increased. Seth Rosenfeld, an analyst at Jeffries International, pointed out that due to strong demand in the world steel market, Turkish steel products that were rejected by the US could be digested by other markets. Since the beginning of this year, the export o...

150 industry associations in the United States call for not to increase taxes on Chinese goods

On September 6, 150 US industry associations jointly sent a letter to the US trade representative, calling for not to impose more tariffs on Chinese goods exports to the United States, and warned that the addition of tariffs would seriously damage the global supply chain and harm US companies and consumers. These industry associations emphasize that it is American companies and people who pay customs duties for importing Chinese goods, not Chinese companies. The US government's tariff on Chinese goods will increase US corporate and consumer spending and weaken the competitiveness of US manufacturers and service providers. They urged the US government not to take further tariff action against China and open comprehensive negotiations with China to resolve trade and investment issues and avoid further escalation of economic and trade frictions. Just the day before, Apple issued an open letter to the US Trade Representative Office, expressing its strong hope that the US gover...

What is the purpose of the oxygen converter blowing process control?

The purpose of the oxygen converter blowing process control is to stabilize the operation, shorten the smelting time, reduce various energy consumption, and improve the end point hit rate, thereby achieving "high yield, high quality, low consumption and labor saving".  In particular, the blowing control requires the formation of alkaline slag as much as possible to speed up the reduction of carbon and slagging.  Under the condition of adding as little auxiliary material as possible, ensure sufficient desulfurization and dephosphorization of molten steel; minimum splashing and slag overflowing during the blowing process, long furnace age, high metal yield, product specifications meet the requirements, energy consumption less.

What are the requirements for lime in converter steel making?

(1) The CaO content is high and the SiO2 content is low. Because the combination of SiO2 and CaO reduces the effective CaO content of lime. (2) The sulfur content is low, and the sulfur content is too high, which affects the desulfurization ability of lime and even increases sulfur. (3) The firing rate is small and the firing rate is large, indicating that a large amount of CaCO3 in the lime does not become CaO. After the furnace is added, CaCO3 decomposes and absorbs heat, which affects the thermal efficiency of the furnace and makes the slagging and temperature control difficult.  (4) The degree of entry into the furnace should be moderate.

briefly describe constant pressure gun operation

The constant flow variable gun position operation is to keep the oxygen supply flow constant during the blowing process of a furnace steel, and to control the blowing by changing the position of the gun to change the interaction between the oxygen flow and the molten pool. Most manufacturers in China use a staged constant flow variable gun position operation. Oxygen lance operation is not exactly the same due to differences in converter tonnage, nozzle structure, raw material conditions, and steel grades. There are currently two lance operation modes. 1 high-low-high-low gun position mode. The open blow gun position is higher, and the initial slag is formed early. When the second batch of rice is added, the gun is lowered at the appropriate time. When the medium-term slag is returned to the dry, the gun can be added or an appropriate amount of flux can be added to adjust the slag fluidity to shorten the blowing time and the end point. Pull carbon out of steel. 2 High-low-low g...
