Business Details

This segment manufactures and sells Graphite Crucibles, Shaped Refractories, and Unshaped Refractories, and purchases and sells Foundry Materials. Its main customers are the automotive-related industry (casting market) and the steel industry (steel market). In addition to domestic manufacturing sites (Osaka Plant and Toyota Plant), the segment also operates overseas through the consolidated subsidiary Asia Refractories Co., Ltd., the non-consolidated subsidiary Nikkodo Trading (Shanghai), and the equity-method affiliate Kyusei Nikkodo (Jiangsu). As the core business accounting for the majority of the Group's sales, this segment's sales ratio was 50.9% in FY2026 (ending March 2026).

Recent Overview

Sales and operating profit both declined significantly year on year, mainly due to lower orders for the steel industry

In FY2026 (ending March 2026), the Refractories Business posted sales of ¥5,203 million (down 4.4% year on year) and operating profit of ¥251 million (down 45.5% year on year), marking a significant decline in profit. While the casting business remained nearly flat, down 0.6% year on year, the steel business declined sharply by 16.0% year on year due to reduced orders at blast furnaces for which the company handles maintenance. The segment's share of Group sales also fell from 55.6% in the prior period to 50.9%, reflecting its relatively diminished presence amid growth in the Engineering Business.

Key Products

product
Graphite Crucibles & Shaped Refractories

Graphite Crucibles are a core product for the casting market (automotive-related industry). Shaped Refractories are supplied to the steel industry and industrial furnaces. The segment is also promoting the rollout of new energy-saving, high-value-added products such as "LITETEX" and "Elemax."

product
Unshaped Refractories

Unshaped Refractories supplied for blast furnaces, converters, and other steel industry applications. This product group is highly susceptible to declines in crude steel production in the steel industry.

product
Foundry Materials

Foundry Materials are purchased and sold to casting plants in the automotive-related industry. Sales from the casting business were ¥4,317 million in FY2026 (ending March 2026), representing 42.2% of segment sales.

product
Refractories for Steel Industry

The company supplies refractories for blast furnaces for which it is responsible for maintenance. In FY2026 (ending March 2026), sales in the steel business fell sharply to ¥955 million (down 16.0% year on year) due to a decline in orders at blast furnaces.

Growth Drivers

  • Expected increase in demand for the casting market as automotive-related production volumes recover (recently turning to year-on-year growth)
  • Expanded sales of new products "LITETEX" and "Elemax" addressing energy-saving and decarbonization needs
  • Strengthened manufacturing and sales of high-value-added products utilizing CIP (Cold Isostatic Pressing)
  • Expansion of overseas operations (contribution from the Chinese joint venture Kyusei Nikkodo (Jiangsu) New Materials Technology Co., Ltd.)
  • New expansion into the electronic devices field, metal powder melting market, and induction furnace market for EVs

Risks

  • Medium- to long-term contraction in casting demand due to declining production volumes and progress of EV adoption in the automotive-related industry, the segment's main customer
  • Decline in orders due to restructuring of steelworks, the shift from blast furnaces to electric furnaces, and the continuing downward trend in crude steel production in the steel industry
  • Rising costs due to surging raw material and fuel prices and the continued weakening of the yen
  • Deterioration of the supply-demand balance due to the slowdown in the Chinese economy and overseas market risk
  • Impact on automotive production from geopolitical risks such as U.S. trade policy and the situation in the Middle East
