冶金部于1982年11月22—25日在包钢召开了高压水螺旋钢菪风口和锻造内芯焊接渣口鉴定会,到会代表来自52个单位,共73人。在会上,包钢有关单位向代表们详细地介绍了高压水螺旋铜管风口和锻造内芯焊接渣口的研制过程和制造工艺。包钢白云鄂博铁矿中含有较高的氟、钾、钠、稀土等元素,致使高炉风口和渣口大量破损,严重影响高炉正常生产。为了解
The Metallurgical Department held a high-pressure water spiral steel scald tuyere and a forging core welding slag mouth appraisal meeting in Baotou from November 22 to November 25, 1982, representing a total of 73 delegates from 52 units. At the meeting, relevant units of Baotou Steel introduced the development process and manufacturing process of high-pressure water spiral copper tuyere and forged core welding slag mouth to the deputies in detail. Baotou Bayanobo iron ore contains high fluorine, potassium, sodium, rare earth and other elements, resulting in a large number of blast furnace tuyere and slag mouth damage, seriously affecting the normal production of the blast furnace.
