To carry out state-level and ministerial-level research projects on electrochemical corrosion resistant steel, low-alloy with high durability steel metallurgy, porous irons, fero-metallurgy, metallurgy of iron ores metallization, shaped coke production for metallurgy, refining steel outside the furnace, to study the manufacture of post-tensioned steel on advanced technological lines, production of CaC2, tin, antimony, pre-treatment of phosphate in cast iron, recycling metals etc.
Scientific and technology advisor for construction steel and fero metallurgy plants.
Since 1990, research to set up the technology, deploy the construction of the first plants for ash, slag treatment of the thermal power plants of Pha Lai, Ninh Binh, Uong Bi... and put the clean fly ash products into cement production at Hoang Thach, Bim Son, Hai Phong Cement Plants... and first time using clean fly ash into making Rolling Concrete (RCC) in the construction of Son La, Ban Ve, Song Tranh 2 hydropowers… and Bai Thuong, Tan Giang… dams etc.
The author owns the “flat explosive” blasting method, capable of pushing a mountain part away to a given distance, the Moscow State University of Mining.
Explosion by “flat explosive”, large-benches stone exploitation for cement plants.
Guiding and practicing at site as required for blasting method of flat explosive and other modern explosive methods such as: Explosion in foundation pit of hydropower works; Explosion in underground water conditions; Adjust the dose of the explosives on the hole to strengthen the rock break, reduce the distance; milisecond blasting through the hole and line, tamping plug segment explosion; Explosion control in strict conditions of safety such as close to high voltage pole, cable car, luxury hotels, etc.
The author owns the technology of producing DAP (diamoniphotphate - (NH3)3PO4) for Lao Cai DAP Factory No. 3, the technology for treatment apatite ore grade II and grade IV, for the first time in chemical field, to allow the putting into use of billions of tons of grade-II and grade-IV ores, which have not been processed before so far. The technology is appraised and approved and report to the Prime Minister by the Ministry of Industry and Trade in 2011. Based on the established technology, the government has approved the policy and the Investor is allocated 250 hectares of land for project implementation.
Technology for reduction, recovery of sulfur in iron ore concentrate, reduction of S content is a harmful component in the iron ore used in steel making.
Technology of exploiting and processing copper ore to copper sulphate, copper powder.
Apply new technologies to build and renovate old mines into modern mines, improve mineral exploitation and processing norms factors so as to raise the economic and social efficiency for enterprises, mines, factories, locals.
