Long Product Technology
Modified Breakdown Mills
CISDI have developed new model breakdown mills (BDCD850, BDCD1,000, BDCD1,350). These have been successfully implemented into the Xingtai Steel quality wire and rod mill, NISCO medium section mill and NISCO Jinxing heavy section mill.
Serialization Mill with Housing
A wide range of high-rigidity housing mills are available, including HSCD700, HSCD610, HSCD560, HSCD480 and HSCD430. These six models can be used in a wide array of applications across the rolling process from acting as a roughing mill through to acting as a pre-finishing mill in either continuous rod rolling or high-speed wire rolling.
Rod & Wire Reducing & Sizing Technology
CISDI offer patented reducing and sizing mills for rods and wires equipped with front and rear water coolers. This contributes to better grain size and dimensional accuracy of medium and small sized rods and high-speed wires. CISDI has good knowledge of reducing and sizing technology for rods, wires and large coils, and is leading the field in China especially for alloy steel products.
CISDI have developed a range of FSCD flying shears for long products, which are applicable for rods as large as Ø130mm and triple-cutting ribbed bar as small as Ø8mm. The cutting speed varies from 0.5m/s to 24m/s. The flying shears can cut premium long products such as straight carbon steel, bearing steel, spring steel and mould steel. The flying shears have been successfully implemented in the premium rod rolling line in Pangang Changchen Steel.
Split Rolling and Controlled Cooling
CISDI provide equipment for double-splitting, triple-splitting and quadric-splitting with a minimum splitting size of 8mm. CISDI can provide controlled cooling technology for rods to enhance the rebar strength, which has been successfully applied in the wire and rod mill of KINSTEEL (Malaysia).
