Business Details

Targeting the steel, non-ferrous metal, cement, glass, ceramics, and environmental equipment-related furnace markets as its primary customer base, this segment manufactures and sells various refractory bricks such as Basic Bricks, High-Alumina Bricks, Clay Bricks, and Silica Bricks, as well as Monolithic Refractories. It is the flagship business accounting for approximately 82% of consolidated net sales, capturing domestic and overseas demand through a two-company structure including the consolidated subsidiary Yingkou Yaojin Refractories Import & Export Co., Ltd. (China). Tokyo Steel Manufacturing Co., Ltd. is a major customer, with sales to it in the fiscal year under review totaling ¥4,408 million (15.04% of total company sales).

Recent Overview

Increased sales and profit in FY2025 driven by higher non-steel orders; decreased in Q3 cumulative FY2026 due to lower ceramics and steel orders

In FY2025 (ending March 2025) (the fiscal year under review), net sales increased 0.9% year on year to ¥24,167 million and segment profit increased 2.5% to ¥4,723 million, driven primarily by an increase in orders for non-steel applications. On the other hand, in the cumulative nine months of FY2026 (ending March 2026) (April to December 2025), net sales declined to ¥17,912 million (down ¥562 million year on year) and segment profit declined to ¥3,412 million (down ¥158 million year on year), turning to decreased sales and profit due to a decline in orders for ceramics and steel applications. Orders received were ¥23,211 million (93.7% of the prior-year level), and the order backlog was ¥9,984 million (91.3% of the prior-year level), indicating softening in orders as well.

Key Products

product
Basic Bricks

Basic refractory bricks used in steel manufacturing equipment such as converters and electric furnaces, as well as non-ferrous metal smelting furnaces. A core product requiring durability under high-temperature, high-load conditions.

product
High-Alumina, Clay, and Silica Bricks

High-Alumina, Clay, and Silica Bricks supplied for cement kilns, glass melting furnaces, and various ceramics furnaces. A diverse product lineup is offered according to application and temperature range.

product
Monolithic Refractories

Monolithic Refractories (such as castables) that can be applied through casting or spraying methods. Widely adopted for repair and new construction of furnace bodies with complex shapes, used across steel, ceramics, and environmental equipment-related furnace applications.

Growth Drivers

  • Diversification of sales composition through increased orders for non-steel applications (ceramics, cement, glass, environmental equipment)
  • Profit improvement through price revisions
  • Proactive sales expansion through increased technical service staff and expanded sales offices
  • Strengthening of low-cost, stable supply structure through equipment rationalization (capital expenditure of ¥2,293 million)
  • Meeting customer needs through new product development

Risks

  • Decrease in orders for steel applications (ceramics and steel orders declined in the cumulative Q3 of FY2026, ending March 2026)
  • Cost pressure from rising raw material and fuel costs, primarily due to yen depreciation
  • Decrease in orders received of 6.3% year on year (¥23,211 million) and decrease in order backlog of 8.7% year on year (¥9,984 million)
  • Risk of dependence on China for raw material procurement and geopolitical risk (instability in Japan-China relations)
  • Increase in depreciation expense due to higher capital expenditure (¥1,314 million, up ¥179 million year on year)
