Large rolling mill

Wide range of production from general section steel to deformed section steel

Manufacturing, quality control, and progress management, from material heating to shipping, are automatically carried out by introducing state-of-the-art equipment and advanced control technology using computers. In addition, we select the most suitable manufacturing process for each product type.

1. Furnace

This is a walking beam type that automatically operates the furnace from material charging to extraction, and also saves energy.

2. BD rolling mill

The specifications are also compatible with H-section steel and deformed section steel.

3. Rough rolling mill

Rough rolling mills No. 1-2, No. 3-4 are arranged in series, and No. 3-4 in particular adopts a drawer type for efficient production according to product type.

4.Universal rolling mill

Efficiently rolls high-precision H-section steel by combining horizontal and vertical rolls.

5. Mist water cooling device

As a countermeasure against thermal bending of products, temperature control is performed in the front stage of the straightening machine to ensure high-precision quality.

6. Automatic piling device

In order to respond quickly and accurately to various needs, label issuance, affixing, bundling, etc. are fully automated.

Medium rolling mill

Producing a wide variety of products in small lots, mainly deformed section steel

Cross-country mills, high-precision finishing rolling mills, and traditional techniques are used to create deformed section steel. Furthermore, we are able to respond flexibly to high-grade and diversified needs through constant technological development, such as the realization of a controlled rolling method, and various cutting-edge equipment.

1. Furnace

Walking beam type heating furnace with many functions for small lot production.

2. BD Mill

A grip tilter suitable for manufacturing deformed section steel is used.

3.R Mill

We use 3Hi and 2Hi rolling mills according to the product type to improve efficiency.

4. Cross-country rolling mill group

A group of cross-country rolling mills capable of producing deformed section steel with high productivity.

5. High rigidity rolling mill

The length of the roll body is shortened and the closed head type suppresses the occurrence of mechanical backlash and improves the dimensional accuracy of the product.

6. Cooling bed

For multi-cutting, we have adopted a two-line arrangement for the conditioning process after the cooling bed.

7. Roll preparation area

This is the workshop where rolls of the next size to be produced and guiding devices are installed in the rolling mill. Efficiency and safety are thoroughly pursued to support small-lot production.
