摘 要
現(xiàn)如今，鎂碳磚在耐火材料中扮演著不可或缺的角色，而耐火材料又在鋼鐵行業(yè)中起著舉足輕重的地位，尤其是鎂碳質耐火材料。鋼鐵行業(yè)的快速發(fā)展帶動著耐火材料的興起，隨著鋼鐵工業(yè)的不斷發(fā)展，對鎂碳磚性能的要求也越來越高，其中鎂碳磚中碳的氧化嚴重影響其使用壽命從而制約其發(fā)展。
鎂碳磚是一種優(yōu)質的耐火材料，是以氧化鎂和碳為主成分，以方鎂石，石墨為主晶相的耐火材料。具有優(yōu)良的抗堿性渣侵蝕的能力和良好的熱震穩(wěn)定性，廣泛應用于轉爐、電爐、鋼包及精煉爐等領域。
本設計是年產50000噸轉爐煉鋼用鎂碳磚MT-14B和MT-18C生產車間設計，采用電熔鎂砂和石墨為主要原料。設計敘述了鎂碳磚的發(fā)展歷史，應用，及損毀機理。并結合物料平衡計算、生產設備的選擇和倉庫等設施的計算結果，以及生產中各環(huán)節(jié)的要求，論述了鎂碳磚生產的工藝理論基礎，詳細敘述了所設計產品的生產工藝流程，并對各工序的設備選擇和工藝布置進行了論證。本設計年產量較大，具有設計工藝過程流暢，設備工作狀況良好，在保證質量的基礎上為降低成本、合理利用不可再生資源，對生產過程中產生的廢磚坯進行回收處理再利用。

Abstract
Nowaday, MgO-C refractory to play an integral role in, and refractory materials and plays a pivotal role in the iron and steel industry, especially the rapid development of carbon refractories magnesium, iron and steel industry, driven by the rise of refractories! With the continuous development of the steel industry, on the MgO-C performance requirements are also increasing, but also seriously affect the oxidation of carbon MgO-C restricting the development of its service life.
MgO-C is a high quality refractories, magnesium oxide, and carbon-based ingredients to periclase, mainly crystalline graphite refractory phase. Has excellent resistance to alkaline slag erosion capability and good thermal shock resistance, widely used converter, electric furnace, ladle refining furnace, and other fields.
This design is to produce 50,000 tons of converter steelmaking MgO-C MT-14B and MT-18C production workshop design, using fused magnesia and graphite as main raw materials. Design describes the history of the development, application, and damage mechanism of Bricks. Combined with the mass balance calculation results and other production equipment selection and warehouse facilities, as well as various aspects of the production requirements, discusses the theoretical basis of MgO-C production process, described in detail the design of the production process, and each step of the process equipment selection and layout were demonstrated. The designed annual output is large, has a smooth design process, the equipment in good working order, on the basis of quality assurance in order to reduce costs, the rational use of non-renewable resources, waste generated during the production of brick recycling and reuse.
