sub-zero coolingとは 意味・読み方・使い方

To obtain sub-zero treated steel sheets having a high flattening degree by applying sub-zero treatment so that binding force is controlled in accordance with the shape before heat treatment of the materials to be heat-treated, and a uniform temperature distribution can be obtained even by cooling for a short time.例文帳に追加

被熱処理材の熱処理前形状に応じて拘束力を調整し、しかも短時間の冷却においても均一な温度分布が得られる深冷処理を行って、平坦度の高い深冷処理鋼板を得る。 - 特許庁

The steel sheets 1 to be treated are flatly straightened before the cooling by the application of the controlled facial pressure from the surface plates, the steel sheets 1 to be treated are uniformly cooled with a cooling medium filled into the metallic square pipes 3 for uniform cooling, and the whole is simultaneously transformed into martensite, thus the flat sub-zero-treated steel sheets can be obtained without the strain remaining.例文帳に追加

被処理鋼板１は定盤から調整された面圧を受けることで冷却前に平坦に矯正され、深冷時、均一冷却用金属製角パイプ３内に充満された冷媒によって被処理鋼板１は均一に冷却され、全体が同時にマルテンサイト変態するため、歪みが残存せずに平坦な深冷処理鋼板が得られる。 - 特許庁
