摘要

The invention provides a method and.device for controlling foamed slag

fumace conditions in iron bath smelting reduction, which comprises the following steps:(l) judging

whethcr foamed slag is lencrated accolding to thc change of the following

indcxes in iron bath smelting reduction production: the sccondary combustion ratc of

coal gas, the calorific value of coal gas, semi-coke amount of flue

gas, the total heat load of water-coolcd wall, thc carbon content of molten iron, the semi-coke content of slag, the density ofslag and the FeO contcnt ofslag; and(2) conirolling the

quaternary basicity ofslag to be 0.70-1.10 by incrcasing the ratio

oithe coal injection amount to the ore injection amount based on the original production parameters, to enable the fumace conditions to fesume normal

production if foamed slag is generated;-and continuing the production according to the original

production parameters if foamed slag is not generated. The control method of the invention realizes the accurate of the foamed slag and by the change of the various

indexes, the rapid resumption of the normal production is realized and the production efliciency is judgrnent improved. The control method of the present invention quantifies

the of the. fumace conditions of the foamed slag and the resumption method in iron bath smelting reduction and fills the gap in the current production technology in the ar1. 1 judgment bases

数据来源 Data Sources

LaoBiz.com 是面向全球企业的老挝商业信息与市场研究平台，帮助企业更高效地了解老挝市场、发现商业机会并寻找潜在合作伙伴。平台商业信息主要来源于老挝政府主管机关维护的官方公开登记系统，包括工贸部 NED（企业注册）、BNED（经营许可）、eBRS（工商登记）与财政部 TaxRIS（税务登记），以及知识产权等相关官方公开渠道。LaoBiz 不创造或修改企业登记事实，而是在上述官方公开信息基础上，通过数据整理、标准化处理、多语言转换、行业分类和智能检索技术，让分散的信息更加易于查询、理解和应用。平台持续关注官方公开数据变化，并通过数据同步机制帮助用户获取企业最新公开状态。

LaoBiz.com is a Laos business-information and market-research platform for global companies—helping users understand the Lao market, discover opportunities and find potential partners more efficiently. Commercial records are drawn mainly from official public registry systems maintained by Lao competent authorities—including MoIC’s NED (enterprise registration), BNED (business licences) and eBRS (business registration), MoF’s TaxRIS (tax registration), and related official public channels such as intellectual-property filings. LaoBiz does not create or alter registry facts; on top of those official public records we organise, standardise, translate, classify by industry and index for search so fragmented filings are easier to find, understand and use. We continuously watch official public-data changes and offer sync tools so users can check an enterprise’s latest public status.

LaoBiz.com 企业详情页提供「同步最新数据」功能。用户可针对指定企业记录主动发起数据核验，平台将根据公开系统返回的信息更新页面展示内容。由于企业登记、税务状态及相关公开信息由不同主管机构维护，数据更新时间可能存在差异。对于商业决策、法律文件、政府审批等正式用途，请以主管机关最新发布的信息及正式文件为准。

Each LaoBiz.com company profile offers “Sync latest data”. Users can actively request verification for a specific enterprise; the page is then refreshed from what the public systems return. Because company registration, tax status and related public filings are maintained by different authorities, update timing may vary. For business decisions, legal documents, government approvals and other formal uses, please rely on the latest information and official documents issued by the competent authority.
