450耐磨板的主要熔化阶段是什么?

所属分类:常见问题 发布时间:2021-04-13 11:18:06 来源:http://www.lcnmb500.com 浏览量:

由于冶炼现场HARDOX450耐磨板时炉渣中会出现大量的MnO,为了防止炉衬被腐蚀,保证脱磷,准确控制硅含量,选择了碱性熔炼炉。电弧炉比其他熔炼炉更容易控制,并且可以返回熔炼,因此碱性电弧炉主要用于钢带熔炼。

Because a large amount of MnO will appear in the slag when smelting hardox450 wear-resistant plate, in order to prevent the lining from corrosion, ensure dephosphorization and accurately control the silicon content, the alkaline smelting furnace is selected. Compared with other smelting furnaces, EAF is easier to control and can return to smelting, so basic EAF is mainly used for steel strip smelting.

首先,熔化期的主要过程如下。

First, the main process of melting period is as follows.

电熔化:熔炉装料,大功率允许。

Electric melting: furnace charging, high power allowed.

(2)推料助熔:在熔炼后期加入适量的矿渣和矿石。当炉料熔化到60-80%时,可以吹氧来帮助熔化。

(2) Pushing material to aid melting: adding appropriate amount of slag and ore in the later stage of smelting. When the charge is melted to 60-80%, oxygen can be blown to help melt.

(3)取样和排渣:熔化时减少电源。炉料完全熔化后,充分搅拌钢水,取钢水分析碳和磷,根据磷含量去除全部或大部分炉渣,制成新的炉渣。

(3) Sampling and slag removal: reduce power supply during melting. After the burden is completely melted, the molten steel is fully stirred, the carbon and phosphorus in the molten steel are analyzed, and all or most of the slag is removed according to the phosphorus content to make a new slag.

(b)氧化阶段有以下两个主要过程。

(b) There are two main processes in the oxidation stage.

(1)氧化脱碳:钢水温度1560以上,炉渣流动性好,吹氧脱碳,吹氧压力0.6-0.5毫升

(1) Oxidation decarburization: molten steel temperature above 1560, good slag fluidity, oxygen blowing decarburization, oxygen blowing pressure 0.6-0.5ml

(2)碳估计取样:当估计钢水的碳含量降低到约0.22%时,停止吹氧。充分搅拌钢水,取钢样分析碳和磷,当磷含量不超过0.015%时,去除氧化渣。

(2) Carbon estimation sampling: when the estimated carbon content of molten steel is reduced to about 0.22%, stop oxygen blowing. When the phosphorus content is less than 0.015%, the oxide slag is removed.
