ore hearthとは 意味・読み方・使い方

A heating plate 12 is arranged between the furnace hearth 5 and a roof 9 in the rotary hearth furnace and a burner 13 is disposed between the heating plate 12 and the roof 9 to indirectly heat the iron ore or the dust on the furnace hearth 5 with the burner 13 through the heating plate 12.例文帳に追加

回転炉床炉の炉床５と天井９との間に加熱板１２を設け、加熱板１２と天井９との間にバーナー１３を設置して、加熱板１２を通して間接的にバーナー１３で炉床５上の鉄鉱石またはダストを加熱する。 - 特許庁

To provide a discharge device of a metal reducing furnace heating an iron oxide mass comprising reducing material such as iron oxide of iron ore, iron manufacture waste, or the like, and charcoal material on a rotary hearth, and discharging a reduced iron mass to the outside of the furnace in regard to a metal reducing furnace having a rotary hearth.例文帳に追加

回転炉床を有する金属還元炉において、回転炉床上で鉄鉱石や製鉄廃棄物などの酸化鉄、炭材等の還元材からなる酸化鉄塊成物を加熱・還元した還元鉄塊成物を炉外に排出する金属還元炉の排出装置を提供する。 - 特許庁

To provide a method for producing reduced iron by which in the case of producing the reduced iron from iron ore by using a shifting-type hearth furnace, dust containing zinc content in the iron ore with the usable concentration as a zinc-refining raw material, can be recovered as high zinc-containing dust.例文帳に追加
