NGC’s main driving gearboxes for hot plate rolling mills are applied to production lines in order to provide enough power for rough and finished rolling zones. The production line has significant rolling reduction and roll force. This is so that the driving system provides high rolling torque and the requirements needed for extreme reliability and stabilization.

These gearboxes include a main reducer with a reduction ratio and a gear housing for power allocation. The power and torque of the main motor can be transmitted to the two rollers of the hot plate after the main reducer and the gear housing are connected.

NGC’s main driving gearboxes for cold plate rolling are applied to production lines of cold plate rolling or reversible type plate rolling mill. They are utilized for transmitting and distributing the power and torque of the motor to the rollers of the rolling mill. To adapt to the demands for high rotating speed and high stabilization, NGC’s main driving gearbox for cold plate rolling is pointedly designed to assure driving requirements, high precision and high reliability, guaranteeing the production lines of the cold plate rolling and the production lines of the reversible type plate rolling mills in many projects.

NGC’s main driving gearbox technology for bar and wire rolling provides solutions for driving systems of production lines of bars, wires, and profiles. These gearboxes are designed by arranging vertical gearboxes and horizontal gearboxes to ensure the shapes and sizes of rolling products. The horizontal gearboxes are driven by parallel shafts, and the vertical gearboxes are driven by spiral bevel gears and parallel shafts. The structure is a single input double output structure or a triple output structure, which can transmit and distribute the power of the motor to two or three rollers, which then will reach the torque and speed required by rolling through reduction ratio.

NGC’s main driving gearbox also features compact structure, compact resistance and steady operation. It can be matched with closed or short stress path rolling mills when used, and can rationally customize the vertical and horizontal structured gearboxes and flat-vertical switching systems according to the requirements of rolling technology of the production lines.

Converter tilting devices are used for tilting and accurately positioning the furnace bodies in oxygen top-blown converters and steelmaking equipment, and in finishing a series of technological operations. This can include converting to add molten iron, tapping steel, adding materials, and repairing furnaces.

NGC’s converter tilting device primarily incorporates an AC variable frequency motor, a primary reducer, a secondary reducer, and a torque arm balancing device. It utilizes four-point meshed fully-suspended flexible driving type, and movement balancing mechanism is a torque arm device. The related core technology of the primary reducer of NGC’s converter tilting device has obtained national patents. The main accessories incorporate top-quality brands to ensure that the performances of the whole device are safe and reliable.

To meet the requirements of different rolling lines, NGC provides different types of flying shear designs, such as crank connecting rod type flying shears, rotary flying shears, and crank connecting rod plus rotary combined flying shears. Besides, NGC also offers various shearing speeds and shearing forces for different structures in different working conditions, even for low-temperature applications, after having cooled the bar and wire rolling products in water.

Being an important equipment in the metallurgy industry, high-speed gearboxes need to meet complex requirements concerning the working conditions, such as offered by NGC.

NGS’s high speed gearboxes for blowers are offered as modular series products. They can be customized according to specific operational environments and working conditions.
