　　据和记百科网站「文艺女王!」消息，近日，高炉炼铁焦炭的作用是什么九年级，请问高炉炼铁焦炭的作用是什么？引发热议，高炉炼铁焦炭的作用是什么九年级同样引起许多争议，对此众网友各抒己见。但到底是怎么回事呢？和记百科为您解答。

高炉炼铁焦炭的作用是什么

　　1、骨架作用：在料柱上部，焦炭起煤气流分配层的作用；在料柱中部，焦炭起骨架作用，支撑着已经熔融的铁矿石，使煤气正常上升；在料柱下部，高温下仍以固态块状存在的焦炭与已经成为液态的铁水和熔渣混在一起，成为煤气上升与铁水、炉渣下降的疏松骨架。

　　2、提供热量：焦炭在焦炉风口前的回旋区内激烈燃烧，燃烧产生的热能是高炉冶炼过程中的主要热源。

　　3、还原作用：焦炭在回旋区内燃烧生成的高温煤气，在上升过程中将热能传给炉料，使之与焦炭发生吸热反应，生成CO和H2，随后CO与铁矿石中的铁氧化物发生还原反应转化为金属铁。

　　问题：【初三化学】炼铁高炉中焦炭的作用是什么?除了提供温度之外还有一个很重要的作用，是什么

　　正确答案：高炉炼铁中焦炭用作燃料（以供给炼铁所需的热量）和还原剂.

　　【英文介绍/For English】：

　　1. Skeleton function: in the upper part of the material column, the coke acts as a distribution layer for gas flow; in the middle of the material column, the coke acts as a skeleton, supporting the molten iron ore and making the gas rise normally; in the lower part of the material column, under high temperature The coke that still exists in solid lumps is mixed with molten iron and molten slag that has become liquid, and becomes a loose skeleton for the rise of gas and the fall of molten iron and slag.

　　2. Provide heat: coke burns violently in the swirl zone in front of the coke oven tuyere, and the heat generated by the combustion is the main heat source in the blast furnace smelting process.

　　3. Reduction: the high-temperature gas generated by the combustion of coke in the swirl zone transfers heat energy to the charge during the rising process, causing it to undergo an endothermic reaction with the coke to generate CO and H2, and then CO and iron in the iron ore are oxidized The material undergoes a reduction reaction and is converted into metallic iron.
