Recently, Tyhen foundation’s low headroom KR300ES rotary drilling rig participated in HeBei TaiHang Iron and Steel Group restructuring relocation project. The project is conducted in the workshop with a height restriction of 11 meters and a narrow construction site. The pile diameter is 800mm with a depth of about 20-31m. Wu'An city is located at the eastern foot of TaiHang Mountain, surrounded by mountains and rolling hills, it is rich in mineral resources with geological conditions constituted by mainly backfill soil, silty clay, weathering and breeze fossil limestone. The geological condition is extremely complicated, and thereby increased the difficulties of construction. KR300ES was able to drill 4 meters deep in the breeze fossil limestone, which is a reflection of the stability and reliability of the rig, as well as the excellent judgment of the operator. With the full support of Tyhen foundation’s engineering experts, the hole was successfully formed and has won over unanimous praise from the contractor.

The restructuring and relocation project of the iron and steel Divison o HeBei TaiHang Iron and Steel Group is part of the "HeBei Province iron and Steel industry structure adjustment program" and it is the 13th five-year development plan of HeBei Province; It is also an important project for HeBei Province to promote the work of reduction of oversupply . The project adopts prolonged metallurgical manufacturing technology, with plans to build two sintering machines covering 300 square meters each, one production line of 1.2 million tons pellet grate and rotary kiln, two blast furnaces sized 1520 cubic meters, two 120 tons converters, one hot rolling line of 1780, and 1 cold rolling line of thin plate. Upon completion, the project will have a production capacity of 2.68 million tons of iron and 2.8 million tons of steel. The implementation of the project bears huge significance to HeBei Province, as it will help in steel production capacity reduction process, equipment upgrading, quality improvement and industrial upgrading; it is also an important step forward to propel HeBei Province's Iron and Steel industry from being large to be strong in production.
