July and August are the hottest months of the year in Chongqing, where CISDI Equipment Co. is based.

This is when our manufacturing teams remain in their workshops and immerse themselves in the many tasks required to keep projects on schedule and to our quality standards.

Good progress has been made in our manufacture of core products for Sichuan Shengquan Steel’s bar and wire-rod mill, Chengdu Chengshi Metallurgy’s rolling mill and spare parts for Chongqing Steel’s bar and wired-rod mill and Hebei Xinjin Steel.

Our equipment manufacturing base, in the Jiangjin District of Chongqing, focuses on the manufacture of pilot and core products and non-standard mechanical equipment integration.

It holds over 200 sets of modernised, high-precision numerical control machine tools and more than 100 sets of advanced measurement and metering units. 

Committed to transforming our core technologies into products, it produces more than 40,000 tonnes of precision core equipment a year.

 

✧         Heavy ladle turret – our core product for continuous casting

CISDI’s large ladle turret features a maximum loading capacity of 450 tonnes at each of its two ladle positions. 27 sets have been supplied. Its equal bearing capacity design is built for super-reliability and stability.

In July, the manufactured ladle turret for Zenith Nantong Steel passed its critical equipment inspection.

Representatives from Zenith Nantong, who attended the workshop inspection with CISDI’s manufacturing team, were impressed by the advanced process, premium quality and also the ladle turret’s eye-catching appearance. Key features include:

-       Larger operational space on the equipment for easier access to its operation and maintenance

-       Upgraded guard and thermal prevention to protect against the high-temperature radiation source and improve working conditions for critical parts, ensuring their operational reliability.

Teams meet for the joint inspection of the ladle turret before its delivery to Zenith Nantong Steel in China’s Jiangsu Province

 

✧         BDCD breakdown mill for special steels’ bar and wire-rod, sections rolling

CISDI’s standard product, the BDCD breakdown mill, is a major player in the global and Chinese long products rolling market due to its stable performance. Showcase references include China’s Shijiazhuang Steel and Hebei Yongyang Special Steel and India’s Aarti Steels.

Featuring large screw-down, high rigidity and super reliability, the BDCD breakdown mill’s highlights are:

-       Hydraulic cobble-free design

-       Hydraulic axial lock

-       Roll’s axial automatic adjustment

-       Hydraulic automatic position control

-       Reduced-labour, fully automatic rolling.

The product is a breakthrough for China’s breakdown mill tech and equipment. Chinese steel producers can now buy reliable, high-performing mills rather than rely on imports.

As an example, a CISDI-supplied breakdown mill was hot-commissioned at a Chinese steel plant in July 2021 and pilot production achieved 800-plus tonnes of output per shift. This was a rebuild project, replacing the original imported mill.

✧         NHCD short-stress path rolling mill for long products rolling

Global sales of CISDI’s NHCD short-stress path rolling mill have soared in the past decade. Over 3,000 sets have now been supplied to 100-plus production lines.

The speciality machining tools and the dedicated, streamlined assembly line at CISDI’s manufacturing shop create the ideal conditions for creating high-quality equipment.

In July, 42 NHCD CISDI-supplied mills were hot-commissioned at the Roughing and Intermediate Mill areas of the Tai’an’ special-purpose building products rolling line at Shiheng’s Special Steel Plant. Auxiliary facilities were also supplied by CISDI.

A leading Chinese producer of building steel products and very particular about its equipment’s tech and quality, Shiheng Special Steel has forged a long-term relationship with CISDI.

August marked another tough schedule for the manufacturing base. Multiple crucial manufacturing tasks began:

ü  Assembly and testing of the vertical and horizontal straighteners, edger mill and universal mill for Hebei Yongyang Steel’s rail and beam project

ü  Manufacturing of tube rolling mills for VALIN Hengyang Steel’s 3-roll cross rolling line (featuring the maximum tube’s diameter Φ720mm)

ü  Unremitting efforts are being made across the manufacturing teams to ensure all targets will be met in the second half of this year.
