SMM News: OSS, whose full name is PT.Obsidian Stainless Steel, is a joint venture between Jiangsu Delong Nickel Co., Ltd. and Xiamen Xiangyu Group. It is a large-scale iron and steel enterprise integrating nickel-iron alloy production and stainless steel smelting. The steelmaking plant was officially put into production in February 2020. On August 18, 2020, the single furnace life of 100t AOD furnace in OSS steelmaking Plant reached 104furnace, which was the highest since OSS steelmaking Plant was put into operation.

AOD furnace life is an important index of stainless steel production cost control. Since the beginning of this year, OSS steelmaking Plant has vigorously carried out the key work of prolonging AOD furnace life.

In the production organization and management, not only do a good job of accurate docking of shifts, but also pay attention to the management of all links from raw materials to smelting, shorten the waiting time for AOD furnace shutdown as much as possible, and speed up thermal turnover.

Technically, the OSS steelmaking plant has carried out in-depth data statistics, furnace life analysis and other index activities to sum up experience, find gaps, analyze causes, explore laws, formulate key measures, reduce slag irrigation consumption, optimize the proportion of fluorite, shorten the smelting cycle, rationalize the mix of furnace charges, control the rhythm from steel charging to tapping, standardize the inclination angle of furnace body charging, and maximize the mother liquid of steel exchange. At the same time, do a good job of temperature control, so as to better prolong the life of the furnace.

In operation, pay close attention to the operation skills of the operators, improve the enthusiasm of the staff, and form a good working atmosphere of catching up with each other. The furnace life of AOD continues to rise. On August 5th, the furnace life of No. 2 AOD reached 101times, and then on August 18th, the furnace life of No. 1 AOD furnace reached 104times, which once again refreshed the best level of AOD furnace life since OSS steelmaking was put into production.

In order to better encourage the workshop staff, the company leaders Li Yufeng and du Yishan made a special trip to bring condolences to the AOD workshop, affirmed the efforts of the AOD workshop, and ignited everyone's confidence to achieve good results again. It promotes the improvement of the core technology of the OSS steelmaking plant, reduces the cost, improves the efficiency, and enhances the core competitiveness of the enterprise.

The emergence of new records also encourages everyone to make continuous improvement, continuous progress, sum up experience and deficiencies, and make continuous efforts. OSS steelmakers will continue to create new steelmaking records of OSS with the spirit of daring to be the first, climbing the peak forever, and challenging the impossible.

High-Grade NPI Smelters Face Profit Pressure Amid Flat Raw Material Prices and Limited Nickel Ore Decline
[SMM Nickel Flash News] Based on the cash cost of high-grade NPI calculated using nickel ore prices from 25 days earlier, profits at high-grade NPI smelters came under pressure during the week, with the sector as a whole remaining in a state of losses or marginal profitability. It is expected that next week, prices of auxiliary materials on the raw material side may remain flat, while the decline in nickel ore prices will likely be limited. High-grade NPI prices will still be under pressure amid back-and-forth negotiations between upstream and downstream, and smelter profits will be unlikely to see any significant improvement.
